BIOLOGICAL BASES OF BEHAVIOR

THE HUMAN BRAIN

The influence of biology (sometimes called the neuroscience or biopsychological perspective) is growing. Some researchers predict that someday psychology will be a specialty within the field of biology. An understanding of the biological principles relevant to psychology is needed to understand current psychological thinking.

Brain Structure

Hindbrain- structures in the top part of the spinal cord, controls basic biological functions that keep us alive. Medulla- controls blood pressure, heart rate, and breathing

Pons- connects the hindbrain with the mid and forebrain, also involved in the control of facial expressions Cerebellum- portion of the lower brain that coordinates and organizes bodily movements for balance and accuracy

Midbrain-between the hind and forebrain, coordinates simple movements with sensory information,

Forebrain- controls what we think of as thought and reason

Thalamus- portion of the lower brain that functions primarily as a central relay station for incoming and outgoing messages from the body to the brain and the brain to the body

Hypothalamus- portion of the lower brain that regulates basic needs (hunger, thirst) and emotions such as pleasure, fear, rage, and sexuality

Amygdala and Hippocampus- two arms surrounding the thalamus, important in how we process and perceive memory and emotion

NOTE: The three parts above are grouped together and called the limbic system because they all deal with aspects of emotion and memory.

Ways of studying the brain

Accidents, Lesions, Electroencephalogram, Computerized axial tomography, Magnetic resonance imaging, Positron emission tomography, Functional MRI

Neuroanatomy

Neuron – a nerve cell, which transmits electrical and chemical information throughout the body

dendrite- part of the neuron that receives information from the axons of other nerve cells

Axon- part of the neuron that carries messages away from one neuron to the dendrites of another

Cell body, or soma- contains the nucleus and other parts of the cell needed to sustain its life

Myelin sheath- a fatty covering around the axon that speeds neural impulses

Terminal buttons- the branched end of the axon that contains neurotransmitters

Vesicles – bubblelike containers of neurotransmitters, located at the end of an axon

Neurotransmitters-– chemicals in the endings of nerve cells that send information across the synapse Acetylcholine – neurotransmitter that regulates basic bodily processes such as movement

Dopamine – a neurotransmitter involved in the control of bodily movements ( involved in Parkinson’s disease, and Alzheimer’s)

Endorphins – neurotransmitters that relieve pain and increase our sense of wellbeing

Serotonin- mood control

Synapse- the junction point of two or more neurons; a connection is made by neurotransmitters.

Action potential

Sympathetic nervous system- speeds things up- prepares body for fight or flight Parasympathetic nervous system-- brings the body back to normal

Cerebral cortex- covers the lower brain and controls mental processes such as thought

Frontal lobes-– contains the motor strip and frontal association area

Frontal association area – plays an important part in integrating personality and in forming complex thoughts

Motor strip- band running down the side of the frontal lobe that controls all bodily movements

Parietal lobes -– area that contains the sensory strip

Sensory strip- band running down the side of he parietal lobe that registers and provides all sensation

Occipital lobes- area that interprets visual information

Temporal lobes- area responsible for hearing and some speech functions

Lobe- major division of the brain

Amplitude – the height of the wave , determines the loudness of the sound, measured in decibels

Frequency - The number of cycles per second in a wave; in sound, the primary determinant of pitch

Hertz (Hz) - Cycles per second; unit of measurement for the frequency of waves

Pitch - Auditory experience corresponding primarily to frequency of sound vibrations, resulting in a higher or lower tone Decibel -The magnitude of a wave; in sound the primary determinant of loudness of sounds

Parts of the ear-

Ear canal – also called the auditory canal

Eardrum-

Hammer, anvil, stirrup - The three small bones in the middle ear that relay vibrations of the eardrum to the inner ear

Oval window - Membrane across the opening between the middle ear and inner ear that conducts vibrations to the cochlea

Round window - Membrane between the middle ear and inner ear that equalizes pressure in the inner ear.

Cochlea - Part of the inner ear containing fluid that vibrates which in turn causes the basilar membrane to vibrate.

Basilar membrane -Vibrating membrane in the cochlea of the inner ear; it contains sense receptors for sound

Organ of Corti -Structure on the surface of the basilar membrane that contains the receptors cells for hearing

Auditory nerve -The bundle of neurons that carries signals from each ear to the brain

PITCH THEORIES- As with color vision, two different theories describe the two processes involved in hearing pitch: place theory and frequency theory.

Place theory -Theory that pitch is determined by the location of greatest vibration of the basilar membrane Frequency theory -Theory that pitch is determined by the frequency wigh which hair cells in the cochlea fire

DEAFNESS

Hearing Loss

People can lose all or some of their ability to hear because of loud noises, infections, head injuries, brain damage and genetic diseases. Hearing loss is common in older people. There are several types of hearing loss:

• Conductive Hearing Loss: occurs when sound vibrations from the tympanic membrane to the inner ear are blocked. This may be caused by ear wax in the auditory canal, fluid buildup in the middle ear, ear infections or abnormal bone growth.
• Sensorineural Hearing Loss: occurs when there is damage to the vestibulocochlear (auditory) nerve. This type of hearing loss may be caused by head injury, birth defects, high blood pressure or stroke.
• Presbycusis: occurs because of changes in the inner ear. This is a very common type of hearing loss that happens gradually in older age.
• Tinnitus: people with tinnitus hear a constant ringing or roaring sound. The cause of this ringing cannot always be found. Some cases of tinnitus are caused by ear wax, ear infections or a reaction to antibiotics, but there are many other possible causes of this disorder.

TOUCH

When our skin is indented, pierced, or experiences a change in temperature, our sense of touch is activated by this energy.

Gate control theory - Theory that a ‘neurological gate in the spinal cord controls the transmission of pain messages to the brain

CHEMICAL SENSES

TASTE (GUSTATION)

Taste buds

Papillae-

Humans sense four different tastes: sweet, salty, sour, and bitter

SMELL (OLFACTION)

The smells of a rose, perfume, freshly baked bread and cookies...these smells are all made possible because of your nose and brain. The sense of smell, called olfaction, involves the detection and perception of chemicals floating in the air. Chemical molecules enter the nose and dissolve in mucous within a membrane called the olfactory epithelium. In humans, the olfactory epithelium is located about 7 cm up and into the nose from the nostrils.

Olfactory epithelium - Nasal membranes containing receptor cells sensitive to odors

Pheromone - Chemical that communicates information to other organisms through smell

VESTIBULAR SENSE – tells us about how our body is oriented in space.

Semicircular canals - Structure in the inner ear particularly sensitive to body roataion.

PERCEPTION

THRESHOLDS

Absolute threshold -The least amount of energy that can be detected as a stimulation 50 percent of the time

Subliminal- stimuli below our absolute threshold

Difference threshold -The smallest change in stimulation that can be detected 50 percent of the time

just-noticeable difference – the smallest amount of change needed in a stimulus before we detect a change

Weber’s Law -The principle that the just noticeable difference for any given sense is a constant proportion of the stimulation being judged.

PERCEPTUAL THEORIES

Psychologists use several theories to describe how we perceive the world.

Signal detection theory- investigates the effects of the distractions and interference we experience while perceiving the world.

Response criteria

False positive

Top-Down Processing – we perceive by filling in gaps in what we sense

Schemata

Perceptual set

STATES OF CONSCIOUSNESS

STATES OF CONSCIOUSNESS

We spend about 8 hours/day, 56 hours/week, 224 hours/month and 2,688 hours/year doing it...that's right...SLEEPING. One third of our lives we are apparently doing nothing. But is sleep really doing nothing? It looks like it...a person's eyes are closed; muscles are relaxed; breathing is regular; there is no response to sound or light. However, if you take a look at what is happening inside the brain, you will find quite a different situation - the brain is very active.

Scientists can record brain activity by attaching electrodes to the scalp and then connecting these electrodes to a machine called an electroencephalograph. The encephalogram (or EEG) is the record of brain activity recorded with this machine. The wavy lines of the EEG are what most people know as "brain waves".

Consciousness is our level of awareness about ourselves and our environment

Conscious level The information about yourself and your environment you are currently aware of. Nonconscious level Body processes controlled by your mind that we are not usually aware of

Preconscious level Information about yourself or your environment that you are not currently Thinking about but you could be.

Subconscious level Information that we are not consciously aware of but we know must exist due to behavior.

Unconscious level. Psychoanalytic psychologists believe some evens and feelings are unacceptable to our conscious mind and are repressed into the unconscious mind. Many psychologists object to this concept as difficult or impossible to prove.

Mere-exposure effect - prefer stimuli we have seen before over novel stimuli

Priming - respond more quickly and/or accurately to questions they have seen before

Blind sight - person being blind being able to grasp an object they cannot see

Abstract learning

· involves understanding concepts such as tree or same

· Skinner box pigeons picking out certain shapes

Insight learning

· Wolfgang Kohler did studies with chimpanzees

What Is Learning?

* Learning is a relatively permanent change in behavior due to experience. Learning resulting from conditioning depends on reinforcement. Reinforcement increases the probability that a particular response will occur.

• Classical (or respondent) conditioning and instrumental (or Operant) conditioning are two basic types of learning.
• In classical conditioning, a previously neutral stimulus begins to elicit a response through association with another stimulus. In operant conditioning, the frequency and pattern of voluntary responses are altered by their consequences.

How does classical conditioning occur?

• Classical conditioning, studied by Pavlov, occurs when a neutral stimulus(NS) is associated with an unconditioned stimulus (US).
• The US causes a reflex called the unconditioned response (UR). If the NS is consistently paired with the US, it becomes a conditioned stimulus (CS) capable of producing a response by itself. This response is a conditioned (learned) response (CR).
• When the conditioned stimulus is followed by the unconditioned stimulus, conditioning is reinforced (strengthened).
• From an informational view, conditioning creates expectancies, which alter response patterns. In classical conditioning the CS creates an expectancy that the US will follow.
• Higher order conditioning occurs when a well-learned conditioned stimulus is used as if it were an unconditioned stimulus, bringing about further learning.
• When the CS is repeatedly presented alone, conditioning is extinguished (weakened or inhibited). After extinction seems to be complete, a rest period may lead to the temporary reappearance of a conditioned response. This is called spontaneous recovery.
• Through stimulus generalization, stimuli similar to the conditioned stimulus will also produce a response. Generalization gives way to stimulus discrimination when an organism learns to respond to one stimulus but not to similar stimuli.

Does Conditioning affect emotions?

• Conditioning applies to visceral or emotional responses as well as simple reflexes. As a result, conditioned emotional responses (CERs) also occur.
• Irrational fears called phobias may be CERs. Conditioning of emotional responses can occur vicariously (secondhand) as well as directly.

How does operant conditioning occur?

• Operant conditioning occurs when voluntary action is followed by a reinforcer. Reinforcement in operant conditioning increases the frequency or probability of a response. This result is based on the law of effect.
• Complex operant responses can be taught by reinforcing successive approximations to a final desired response. This is called shaping. It is particularly useful in training animals.
• If an operant response is not reinforced, it may extinguish (disappear). But after extinction seems complete, it may temporarily reappear (spontaneous recovery).

Are there different kinds of operant reinforcement?

• In positive reinforcement, a reward or pleasant event follows a response. In negative reinforcement, a response that ends discomfort becomes more likely.
• Primary reinforcers are “natural”, physiologically based rewards. Intracranial stimulation of ‘pleasure centers’ in the brain can also serve as a primary reinforcer.
• Secondary reinforcers are learned. They typically gain their reinforcing value by direct association with primary reinforcers or because they can be exchanged for primary reinforcers. Tokens and money gain their reinforcing value in this way.
• Feedback, or knowledge of results, aids learning and improves performance. It is most effective when it is immediate, detailed and frequent.
• Programmed instruction breaks learning into a series of small steps, and provides immediate feedback. Computer-assisted instruction (CAT) does the same but has the added advantage of providing alternate exercises and information when needed. Four variations of CAI are drill and practice, instructional games, educational simulations, and interactive videodisk instruction.

How are we influenced by patterns of reward?

• delay of reinforcement greatly reduces its effectiveness, but long chains of responses may be built up so that a single reinforcer maintains many responses.
• Superstitious behaviors often become part of response chains because they appear to be associated with reinforcement….
• Reward or reinforcement may be given continuously (after every response) or on a schedule of partial reinforcement. Partial reinforcement produces greater resistance to extinction.
• The four most basic schedules of reinforcement are fixed ratio, variable ratio, fixed interval, and variable interval. Each produces a distinct pattern of responding.
• Stimuli that precede a reinforced response tend to control the response on future occasions (stimulus control). Two aspects of stimulus control are generalization and discrimination.
• In generalization an operant response tends to occur when stimuli similar to those preceding reinforcement are present.
• In discrimination, responses are given in the presence of discriminative stimuli associated with reinforcement (S+) and withheld in the presence of stimuli associated with nonreinforcement (S-)

What does punishment do to behavior?

• Punishment decreases responding. Punishment occurs when a response is followed by the onset of an aversive event or by the removal of a positive event (response cost)
• Punishment is most effective when it is immediate, consistent and intense. Mild punishment tends to only temporarily suppress responses that are also reinforced or were acquired by reinforcement.
• The undesirable side effects of punishment include the conditioning of fear to punishing agents and situations associated with punishment, the learning of escape and avoidance responses, and the encouragement of aggression.

What is cognitive learning?

• Cognitive learning involves higher mental processes. such as understanding, knowing, or anticipating. Even in relatively simple learning situations, animals and people seem to form cognitive maps (internal representations or relationships).
• In latent learning, learning remains hidden or unseen until a reward or incentive for performance is offered.
• Discovery learning emphasizes insight and understanding, in contrast to rote learning.

Does learning occur by imitation?

• Much human learning is achieved through observation, or modeling. Observational learning is influenced by the personal characteristics of the model and the success or failure of the model’s behavior. Studies have shown that aggression is readily learned and released by modeling.
• Television characters can act as powerful models for observational learning. Televised violence increases the likelihood of aggression by viewers.

How does conditioning apply to practical problems?

• Operant principles can be readily applied to manage behavior in everyday settings. When managing one’s own behavior, self-reinforcement, self-recording, feedback, and behavioral contracting are all helpful.
• Four strategies that can help change bad habits are reinforcing alternate responses, promoting extinction, breaking response chains, and avoiding antecedent cues.
• In school, self-regulated learners typically do all of the following: They set learning goals, plan learning strategies, use self-instruction, monitor their progress, evaluate themselves, reinforce successes, and take corrective action when required.

How does biology influence learning?

• Many animals are born with innate behavior patterns far more complex than reflexes. These are organized into fixed action patterns (FAPs), which are stereotyped, species-specific behaviors.
• Learning in animals is limited at times by various biological constraints and species-typical behaviors.
• According to prepared fear theory, some stimuli are especially effective conditioned stimuli.
• Many responses are subject to instinctive drift in operant conditioning. Human learning is subtly influenced by many such biological potentials and limits

MEMORY

Memory is any indication that learning has persisted over time

Several different models, or explanations, of how memory works have emerged from memory research. Two of the most important models: the three-box/information processing model and the levels of processing model. Neither model is perfect.

Three Box model proposes the three stages that information passes through before it is stored:

Sensory memory

- split-second holding tank

- the information your senses are processing right now is held in sensory memory

- less than a second

- George Sperling did experiments, showed iconic memory – a split-second perfect photograph of a scene

- Other experiments indicate echoic memory – split-second memory for sounds

- Most of the information in sensory memory is not encoded

- Selective attention determines which sensory messages get encoded

Short-term/Working Memory

- memories we are currently working with

- temporary, they usually fade in 10 to 30 seconds

- capacity is limited on average to around seven items

- Events are encoded as visual codes, acoustic codes, or semantic codes

- Capacity can be expanded through chunking

- Mnemonic devices- memory aids, really examples of chunking

- Rehearsal or simple repetition can hold information in short-term memory

Long-term Memory

- permanent storage

- capacity is unlimited

- memories can decay or fade

- stored in three different formats

Episodic memory – memories of specific events stored in a sequential series of events

Semantic memory – general knowledge of the world stored as facts, meanings, or categories rather than sequentially

Procedural Memory – memories of skills and how to perform them, These are sequential but might be very complicated to describe in words.

Memories can also be implicit or explicit

Explicit – also called declarative – conscious memories of facts or events

Implicit – also called nondeclarative- unintentional memories that we might not even realize we have

LEVELS OF PROCESSING MODEL

This theory explains why we remember what we do by examining how deeply the memory was processed or thought about. Memories are neither short- nor long-term. They are deeply (or elaboratively) processed or shallowly (or maintenance) processed.

According to the levels of processing theory, we remember things we spend more cognitive time and energy processing. This theory explains why we remember stories better than a simple recitation of events and why, in general, we remember questions better than statements.

RETRIEVAL

- getting information

- two different kinds: recognition and recall

There are several factors that influence why we can retrieve some memories and why we forget others.

- Primacy effect – more likely to recall items presented at the beginning of a list

- Recency effect- ability ot recall the items at the end of a list

- Context - semantic network theory

- Flashbulb memories

- Mood-congruent memory- ability to recall a memory is increased when current mood matches mood when stored

- State-dependent memory-

Constructive Memory – false memories, leading questions can easily influence us.

FORGETTING

One cause is decay, because we do not use a memory or connection to a memory for a long time. Relearning effect indicates that it isn’t entirely gone

Another factor is interference, two types

- Retroactive interference – learning new information interferes with the recall of older information

- Proactive interference – older information learned previously interferes with the recall of information learned more recently

How memories are physically stored in the brain.

- the hippocampus is important in encoding new memories. Damage can cause anterograde amnesia (can’t encode any new memories)

- long-term potentiation- studies of neurons indicate that they can strengthen connections between each other through repeated firings, this might be related to the connections we make in our long-term memory

LEARNING AND MEMORY

Learning - the process by which experience or practice results in a relatively permanent change in behavior or potential behavior

Conditioning- the acquisition of specific patterns of behavior in the presence of well-defined stimuli

Classical or Pavlovian conditioning - type of learning in which a response naturally elicited by one stimulus comes to be elicited by a different, neutral stimulus

Operant or instrumental conditioning - type of learning in which behaviors are emitted to earn rewards to avoid punishments

Unconditioned stimulus US - stimulus that invariably causes an organism to respond in a specific way

Unconditioned response (UR) -response that takes place in an organism whenever an unconditioned stimulus occurs

Conditioned response - after conditioning, the response an organism produces when only a conditioned stimulus is presented

Desensitization therapy - conditioning technique designed to gradually reduce anxiety about a particular object or situation

Taste aversion - conditioned avoidance of poisonous food

Operant behavior - behavior designed to operate on the environment in a way that will gain something desired or avoid something unpleasant

Reinforcer - a stimulus that follows a behavior and increases the likelihood that the behavior will be repeated

Punisher - a stimulus that follows a behavior and decreases the likelihood that the behavior will be repeated

Law of effect - Thorndike’s theory that behavior consistently rewarded will be ‘stamped in’ as learned behavior

Positive reinforcer - Any event whose presence increases the likelihood that ongoing behavior will recur

Negative reinforcer - Any event whose reduction or termination increases the likelihood that ongoing behavior will recur

Avoidance training - Learning a desirable behavior to prevent an unpleasant condition such as punishment from occurring

Response acquisition - ‘building phase’ of the conditioning during which the likelihood or strength of the desired response increases

Intermittent pairing - pairing the conditioned stimulus and the unconditioned stimulus on only a portion of the learning trials

Skinner box - box that is often used in operant conditioning of animals. It limits the available responses and thus increases the likelihood that the desired response will occur

Shaping - reinforcing successive approximations of a desired behavior

Extinction - decrease in the strength or frequency of a learned response due to failure to continue pairing the US and CS or the withholding of reinforcement

Spontaneous recovery - the reappearance of an extinguished response after the passage of time

Stimulus generalization - transfer of a learned response to different but similar stimuli

Stimulus discrimination - learning to respond to only one stimulus and to inhibit the response to all other stimuli

Response generalization - giving a response that is somewhat different from the response originally learned to that stimulus

Primary reinforcer - reinforcer that is rewarding in itself, such as food, water, and sex

Secondary reinforcer - reinforcer whose value is learned through association with other primary or secondary reinforcers

Contingency - a reliable ‘if-then’ relationship between two events such as a CS and US

Blocking - prior conditioning prevents conditioning to a second stimulus even when the two stimuli are presented simultaneously

Schedule of reinforcement - in partial reinforcement, the rule for determining when and how often reinforcers will be delivered

Fixed-interval schedule - reinforcement schedule that calls for reinforcement of a correct response after a fixed length of time

Variable-interval schedule - reinforcement schedule in which a correct response is reinforced after varying lengths of time after the last reinforcement

Fixed-ratio schedule - reinforcement schedule in which the correct response is reinforced after a fixed number of correct responses

Variable-ratio schedule - reinforcement schedule in which a varying number of correct responses must occur before reinforcement is presented

Cognitive learning - learning that depends on mental processes that are not directly observable

Latent learning -learning that is not immediately reflected in a behavior change

Cognitive map - a learned mental image of a spatial environment that may be called on to solve problems when stimuli in the environment change

Learning set - ability to become increasingly more effective in solving problems as more problems are solved

Negative transfer – an interference with learning due to differences between two otherwise similar tasks

Information processing – the methods by which we take in, analyze, store, and retrieve material

Schema – an organized and systematic approach to answering questions or solving problems

Elaboration – the process of attaching a maximum number of associations to a basic concept or other material to be learned so that it can be retrieved more easily

Mnemonic devices – unusual associations made to material to aid memory

Principle learning – a method of learning in which an overall view (principle) of the material to be learned is developed so that the material is better organized

Chunking – putting things into clusters or ‘chunks’ so that items learned are in groups, rather than separate

Forgetting – an increase in errors when trying to bring material back from memory

Overlearning – the process of learning something beyond one perfect recitation so that the forgetting curve will have no effect; the development of perfect retention.

Forgetting curve – graphic representation of speed and amount of forgetting that occurs

Recall – the ability to bring back and integrate many specific learned details

Recognition – the ability to pick the correct object or event from a list of choices

Interference theory – the belief that we forget because new and old material conflict with one another

Amnesia – the blocking of older memories and/or the loss of new ones

Short-term memory – the memory system that retains information for a few seconds to a few minutes

Long-term memory – the memory system that retains information for hours, days, weeks, months, decades

Sensory memory system – direct receivers of information from the environment – for example, iconic, acoustic

Iconic memory – a very brief visual memory that can be sent to the STM

Acoustic memory – a very brief sound memory that can be sent to the STM

Eidetic imagery – an iconic memory lasting a minute or so that keeps images ‘in front of the person’ so objects can be counted or analyzed, also called ‘photographic memory’

COGNITION

LANGUAGE

Language is intimately connected to cognition

Elements

-phonemes

-morphemes

-syntax

Language Acquisition-

First stage – babbling

- babbling appears to be innate

- babies in this stage are capable of producing any phoneme from any language

- babbling progresses into utterances of words as babies imitate the words they hear caregivers say

Second stage – telegraphic speech

- combine words into simple commands

- begin to learn grammar and syntax rules during this stage

Controversy in language acquisition

-Behaviorists believe it is learned through operant conditioning and shaping

-Noam Chomsky – nativist theory of language acquisition, says humans are born with a language acquisition device which allows them to learn language rapidly. There may be a critical period for learning language.

-Most psychologists now agree that there is some combination of the two

Language and Cognition

Benjamin Whorf, linguistic relativity hypothesis – the language we use might control, and in some ways limit, our thinking

THINKING AND CREATIVITY

Schemata – cognitive rules we use to interpret the world

Concepts- similar to schemats, rules that allow us to categorize and think about the objects, people, and ideas we encounter

Prototypes – the most typical example of a particular concept

Images – mental pictures

Problem Solving

Algorithms – try every possible solution,, an algorithm is a rule that guarantees the right solution by using a formula or foolproof method, may be impractical

Heuristics –a rule of thumb,it limits the possible combinations drastically

Availability heuristic- judging a situation based on examples of similar situations that come to mind initially.

Representativeness heuristic – judging a situation based on how similar the aspects are to prototypes the person holds in his or her mind.

Use of the heuristics can lead to specific problems in judgments. Overconfidence, belief bias, belief perseverance

Impediments to Problem Solving-

- rigidity (mental set) tendency to fall into established thought patterns

- functional fixedness – the inability to see a new use for an object

- not breaking the problem into parts

- confirmation bias – we tend to look for evidence that confirms our beliefs

- Framing – the way a problem is presented

Creativity

- little correlation between intelligence and creativity

- difficult to define, originality, appropriateness, novel, somehow fits the situation

- convergent thinking- thinking pointed toward one solution

- divergent thinking- thinking that searches for multiple possible answers to a question - divergent thinking is more closely associated with creativity.

MOTIVATION AND EMOTION

Darwin’s theory of natural selection caused many psychologists to try and explain all human behaviors through instincts, most agree that our behavior is motivated by other biological and psychological factors.

Drive reduction theory – behavior is motivated by biological needs. A need is one of our requirements for survival, a drive is our impulse to act in a way that satisfies this need

Homeostasis- balanced internal state

Drives are primary and secondary-

Primary- biological needs like thirst and hunger

Secondary – learned drives like money

Drive reduction theory cannot explain all our motivations.

Arousal Theory- states that we seek an optimum level of excitement or arousal, most of us perform best with an optimum level of arousal.

Yerkes-Dobson law –high level of arousal may cause us to perform well at easy tasks but poorly on difficult tasks.

Incentive Theory – sometimes behavior is pulled by a desire, incentives are stimuli that we are drawn to due to learning

Maslow’s Hierarchy of Needs – Abraham Maslow pointed out that not all needs are created equal

Hunger Motivation – Why do we become hungry

Biological Basis – There are several biological factors

- Stomach sensation of being full

- Hypothalamus, specifically the lateral and ventomedial parts if destroyed or stimulated determine hunger

- Set-point theory, says hypothalamus wants to maintain a certain optimum body weight

Psychological factors

- external cues, attractiveness or availability of food

Garcia effect, learned taste aversions -

Culture and background

Eating Disorders – different cultures have drastically different rates of eating disorders, rates are highest in the U.S. The three most common are:

Bulimia – Bulimics eat large amounts of food in a short period of time and then get rid of the food by vomiting, excessive exercise, or the use of laxatives. (Binge then Purge) Bulimics are obsessed with food and their weight, the majority of bulimics are women

Anorexia Nervosa - Anorexics starve themselves to below 85 percent of their normal body weight and refuse to eat due to their obsession with weight, the vast majority are women

Obesity – People with diagnosed obesity are severely overweight, often over 100 pounds, and the excess weight threatens their health. Obese people typically have unhealthy eating habits rather than the food obsessions of the other two disorders. Some people may also be genetically predisposed to obesity

Social Motivation –

Achievement Motivation – Humans seem to be motivated to figure out our world

and master skills, sometimes regardless of the benefits of the skills or knowledge. Studies involve looking at differences in how people set and meet personal goals and go about acquiring new knowledge or skills.

Extrinsic/Intrinsic Motivation-

Extrinsic motivators are rewards that we get for accomplishments from outside ourselves Ex. Grades, salary, etc.

Intrinsic motivators are rewards we get internally, such as enjoyment or satisfaction

Knowing what type of motivation an individual responds best to can give managers insight into what strategies will be most effective. Extrinsic motivators are effective for a short period of time but studies show that if we want a behavior to continue, intrinsic motivation is most effective.

Management Theory – studies of management styles show two basic attitudes that affect how managers do their jobs:

Theory X – managers believe that employees will work only if rewarded with benefits or threatened with punishment

Theory Y – managers believe that employees are internally motivated to do good work and policies should encourage this internal motive.

THEORIES ABOUT EMOTION –

James-Lange – They theorized that we feel emotion because of biological changes, physiological change causes emotion

Cannon-Bard – They doubted this order, they demonstrated that similar physiological changes correspond with drastically different emotional states. Biological change and the cognitive awareness of the emotional state occur simultaneously

Two Factor Theory – Stanley Schacter explains emotional experiences in a more complete way than either previous. He pointed out that both our physical responses and our cognitive labels combine to cause any particular emotional response. Emotion depends on the interaction between two factors, biology and cognition.

STRESS – stress and emotion are intimately connected concepts. The term stress can refer to either certain life events (stressors) or how we react to these changes in the environment (stress reactions)

Measuring stress – Thomas Holmes and Richard Rahe designed one of the first instruments to measure stress. Their social readjustment rating scale (SRRS) measured stress using life-change units (LCUs). Any major life change increases the score on the SRRS, a person who scored very high on the SRRS is more likely to have stress-related diseases than a person with a low score.

General Adaptation Syndrome (GAS) – Hans Seyle describes the general response in humans and animals to stressful events. There are three stages:

Alarm reaction – Heart rate increases, blood is diverted away from other body functions to muscles needed to react. The organism readies itself to meet the challenge through activation of the sympathetic nervous system.

Resistance – The body remains physiologically ready. Hormones are released to maintain this state of readiness. If the resistance stage lasts too long, te body can deplete its resources.

Exhaustion – The parasympathetic nervous system returns our physiological state to normal. We can be more vulnerable to disease in this stage especially if our resources were depleted by an extended resistance stage.

Various studies show that a perceived lack of control over events exacerbates the harmful effects of stress, control over events tends to lessen stress.

PERSONALITY

Personality is the unique attitudes, behaviors, and emotions that characterize a person.

PSYCHODYNAMIC THEORIES

Sigmund Freud- personality was essentially set in early childhood, psychosexual stages

Three parts to personality- id, ego, superego

Id contains instincts and energy. Two types of instincts:

Eros- life instinct; often evidenced as a desire for sex

Thanatos – the death instinct;; seen in aggression

Defense Mechanisms-

Carl Jung- proposed unconscious consists of two different parts

Personal unconscious- similar to Freud’s idea, contains painful memories and thoughts the person does not wish to confront, complexes

Collective unconscious- passed down through the species, explains certain similarities we see between all cultures, contains archetypes (universal concepts we all share

Shadow- the evil side of personality

Persona- people’s creation of a public image

Alfred Adler – ego psychologist, downplayed the importance of the unconscious, Thought people are motivated by the fear of failure, inferiority; and the desire to achieve, superiority. Also known for his work on the importance of birth order.

TRAIT THEORIES

Trait theorists believe we can describe people’s personalities by specifying their main characteristics or trait

Nomothetic approach. Theorists that believe that the same basic set of traits can be used to describe all people’s personalities

Hans Eyesenck- believed could classify all people along introversion-extraversion scale and a stable-unstable scale

Raymond Cattell- 16PF (personality factor) 16 basic traits in all people in varying degrees

A number of contemporary trait theorists believe that personality can be described using the big five personality traits- extraversion, agreeableness, conscientiousness, openness to experience, emotional stability

The number of traits is derived from factor analysis- a statistical technique that allows researchers to use correlations between traits.

Idiographic theorists- argue that each person should be seen in terms of the few traits that best characterize their uniqueness

Gordon Allport- created a measure to identify each person’s ‘central traits’

TESTING AND INDIVIDUAL DIFFERENCES

INTELLIGENCE

Intelligence is often defined as a measure of general mental ability. Of the standardized intelligence tests, those developed by David Wechsler are among those most widely used. Wechsler defined intelligence as “the global capacity to act purposefully, to think rationally, and to deal effectively with the environment.” While psychologists generally agree with this definition, they don’t agree on the operational definition of intelligence (that is, a statement of the procedures to be used to precisely define the variable to be measured) or how to accomplish its measurement.

Test Construction- To be useful must use established criteria of standardization, reliability, and validity

· Standardization – process of making uniform and objective both testing procedures and scoring procedures in order to obtain meaningful scores.

· Reliability – refers to the consistency of results. Different types:

- test and retest reliability – comparison of original test scores with retest scores

- alternate form reliability – comparison of scores obtained on alternate forms of a test

- split-half reliability – comparison of scores obtained on two halves of tests

· Validity – refers to the extent that a test measures what it is supposed to measure. Types include:

- content validity – the extent to which a test reflects a sample of the behavior to be measured

- predictive validity – the extent to which a test can predict a person’s behavior in another situation

- face validity – how appropriate a test ‘appears’ to be, just from the way the items read

- construct validity – how well a test assesses the construct for which it was designed

- concurrent validity – how well the results of a test agree with those of a new test or a different form of the test measuring for the same construct

Measures of Intelligence. Several individual tests have been used to test intelligence.

· The Binet-Simon intelligence scale, Developed by Frenchmean Alfred Binet, was administered to children to evaluate their performance (mental age) at a given chronological age, this measure called a mental quotient, was used to evaluate a child’s learning potential.

· Lewis Terman of Stanford University revised the Binet scale, called the Stanford-Binet intelligence scale, it introduced the concept of intelligence quotient

· David Wechsler developed the WAIS and the WISC, the revised forms of these tests are still widely used. They contain two subscales, verbal and performance.

Tests of aptitude and achievement. Group tests, like the SAT measure aptitude, or the capacity to learn and achievement, what has been learned.

Ranges of intelligence scores. The two extremes of levels of intellectual functioning are known as developmentally disabled and gifted.

· Those identified as mentally retarded or developmentally disabled have IQ scores of 70 or below. Mild (50-70), moderate (35-50), severe (20-35), profound (below 20). Causes include Down syndrome, a genetic disorder; phenylketonuria, a metabolic disorder; and developmental disability due to anoxia (lack of oxygen) during gestation.

· The gifted usually fall within the upper 2% to 3% of the IQ score distribution (between 130 and 145). Louis Terman’s study of the gifted found they possess high IQ but also superior potential in any of six areas; general intelligence, specific aptitudes, creativity, leadership, performing arts, and athletics.

Other concepts of intelligence-

· Spearman’s two-factor theory. Charles Spearman believed intelligence was made up of two components; a g-factor (general intelligence) and s-factors (a collection of specific cognitive intellectual skills)

· Thurstone’s primary mental abilities. L.L. Thurstone proposed seven categories of primary mental abilities: verbal comprehension, number, spatial relations, perceptual speed, word fluency, memory, inductive reasoning or general reasoning. Each ability could be measured separately and the sum composes intelligence.

· Guilford’s three-dimensional model. Proposed three dimensions of mental ability:

- operations- the act of thinking

- contents – the terms used in thinking

- products of thinking – ideas

Each dimension is subdivided and the combinations can lead to over 100 separate factors.

· Fluid and crystallized intelligence. Raymond Cattell and John Horn suggested that the g-factor should be divided into:

- Fluid intelligence- reasoning ability, memory capacity, and speed of information processing. Involves such skills as those requiring spatial and visual imagery and is generally believed to be much less affected by experience and education than crystallized intelligence.

- Crystallized intelligence – concerns the application of knowledge to problem solving. Includes abilities such as reasoning and verbal and numerical skills and is generally believed to be affected by experience and education.

· Vernon’s hierarchical model. Suggests that intelligence consists of factors and skills arranged hierarchically. The cognitive factor, at the top, is composed of two skills, verbal/academic and practical/mechanical

· Sternberg’s triarchic theory. Concerned with how intelligence is used, theory deals with:

- componential intelligence, includes components essential to acquisition of knowledge and use of problem-solving strategies

- experiential intelligence, reflected in creatively dealing with new situations and combining different experiences in insightful ways

- contextual intelligence, reflected in the management of day-to-day affairs

· Gardner’s seven intelligences, Howard Gardner divided intelligence into seven abilities:

- linguistic ability

- logical-mathematical

- spatial ability

- musical ability

- bodily-kinesthetic ability

- interpersonal ability

- intrapersonal ability

ABNORMAL

Defining abnormal behavior is difficult. It generally has the following characteristics.

- it is maladaptive and/or disturbing to the individual

- it is disturbing to others

- it is atypical, not shared by many members of the population

- it is irrational

Different schools of thought have different perspectives on the causes of disorders

Perspective Cause of disorder

Psychoanalytic/psychodynamic Internal, unconscious conflicts

Humanistic Failure to strive toward one’s potential or being out of touch with one’s feelings

Behavioral Reinforcement history, the environment

Cognitive Irrational, dysfunctional thoughts or ways of thinking

Sociocultural Dysfunctional society

Biomedical Organic problems, biochemical imbalances genetic predispositions

CATEGORIES OF DISORDERS

Anxiety Disorders – share the common symptom of anxiety

- phobia

- generalized anxiety disorder, often referred to as GAD (previously called anxiety state)

- obsessive-compulsive disorder

- posttraumatic stress disorder- involves flashbacks or nightmares following a person’s involvement in or observation of an extremely troubling even

Somatoform Disorders- when a person manifests a psychological problem through a physiological symptom

- hypochondriasis

- conversion disorder

Dissociative Disorders

- psychogenic amnesia

- fugue

- multiple personality disorder

Mood or Affective Disorders- involves extreme or inappropriate emotions

- Major depression also known as unipolar depression- the most common mood disorder. Key factor is the length of the depressive episode. Other symptoms- loss of appetite, fatigue, change in sleeping patterns, lack of interest in normally enjoyable activities, feelings of worthlessness

- Seasonal Affective Disorder (SAD) – experience depression only in certain parts of the year, winter, treated with light therapy

- Bipolar disorder, also know as manic depression- involves both depressed and manic episodes

Theories on causes

- Aaron Beck, cognitive theorist says comes from unreasonably negative ideas that people have about themselves, their world, and their futures- cognitive triad. Also attributional theory applies

- Has been found to correlate with feelings of learned helplessness

- Evidence suggests a biological component- low levels of serotonin

Schizophrenic Disorders – fundamental symptom is disordered, distorted thinking often demonstrated through delusions and/or hallucinations. There are four kinds

- Disorganized schizophrenia- evidence odd uses of language, make up their own words (neologisms), make clang associations, inappropriate affect or flat affect

- Paranoid schizophrenia- delusions of persecution

- Catatonic schizophrenia- engage in odd movements, stupor, move jerkily and quickly for no apparent reason, waxy flexibility. Increasingly rare

- Undifferentiated schizophrenia- exhibit disordered thinking but no symptoms of one of the other types of schizophrenia

Causes- most popular ideas is biological, dopamine hypothesis, people with schizophrenia have high dopamine levels. Also, enlarged ventricles and brain asymmetries, also seems to be genetic predisposition

Obsessive-compulsive personality disorder

How is normality defined, and what are the major psychological disorders?

• Psychopathology refers to maladaptive behavior and to the scientific study of mental, emotional, and behavioral disorders.
• Definitions of normality usually take into account the following; subjective discomfort, statistical abnormality, social nonconformity, and the cultural or situational context of behavior.
• Two key elements in judgments of disorder are that a person’s behavior must be maladaptive and it must involve a loss of control.
• Major mental disorders include psychotic disorders, dementia, substance related disorders, mood disorders, anxiety disorders, somatoform disorders, dissociative disorders, personality disorders, and sexual or gender identity disorders.
• Traditionally, the term neurosis has been used to describe milder, anxiety-related disorders. However, the term is fading from use.
• Insanity is a legal term defining whether a person may be held responsible for his or her actions. Sanity is determined in court on the basis of testimony by expert witnesses.

What is a personality disorder?

• Personality disorders are deeply ingrained maladaptive personality patterns.
• Sociopathy is a common personality disorder. Antisocial people seem to lack a conscience. They are emotionally unresponsive, manipulative, shallow, and dishonest.

What problems result when a person suffers high levels of anxiety?

• Anxiety disorders, dissociative disorders, and somatoform disorders are characterized by high levels of anxiety, rigid defense mechanisms, and self-defeating behavior patterns.
• The term nervous breakdown has no formal meaning. However, ‘emotional breakdowns’ do correspond somewhat to adjustment disorders.
• Anxiety disorders include generalized anxiety disorder, panic disorder with or without agoraphobia, agoraphobia (without panic), specific phobias, social phobia, obsessive-compulsive disorders, post-traumatic stress disorder, and acute stress disorder.
• Dissociative disorders may take the form of dissociative amnesia, dissociative fugue, or dissociative identity disorder.
• Somatoform disorders center on physical complaints that mimic disease or disability. Four examples of somatoform disorders are hypochondriasis, somatization disorder, somatoform pain disorder, and conversion disorders.

How do psychologists explain anxiety-based disorders?

• The psychodynamic approach emphasizes unconscious conflicts as the cause of disabling anxiety.
• The humanistic approach emphasizes the effects of a faulty self-image.
• The behaviorists emphasize the effects of previous learning, particularly avoidance learning.
• Cognitive theories of anxiety focus on distorted thinking, judgment, and attention.

What are the general characteristics of psychosis?

• Psychosis is a break in contact with reality that is marked by delusions, hallucinations, sensory changes, disturbed emotions, disturbed communication, and, in some cases, personality disintegration.
• An organic psychosis is based on known injuries or diseases of the brain. Other problems of unknown origin are termed functional psychoses.
• Some common causes of organic psychosis are untreated syphilis, poisoning, drug abuse, and dementia (especially Alzheimer’s disease).

How do delusional disorders differ from other forms of psychosis?

• A diagnosis of delusional disorder is almost totally based on the presence of delusions of grandeur, persecution, infidelity, romantic attraction, or physical disease.
• The most common delusional disorder is paranoid psychosis. Paranoids may be violent if they believe they are threatened.

What forms does schizophrenia take? What causes it?

• Schizophrenia involves a split between thought and emotion, delusions, hallucinations, and communication difficulties.
• Disorganized schizophrenia is marked by extreme personality disintegration and silly, bizarre, or obscene behavior. Social impairment is usually extreme.
• Catatonic schizophrenia is associated with stupor, mutism and odd postures. Sometimes violent and agitated behavior also occurs.
• In paranoid schizophrenia (the most common type), outlandish delusions of grandeur and persecution are coupled with psychotic symptoms and personality breakdown.
• Undifferentiated schizophrenia is the term used to indicate a lack of clear-cut patterns of disturbance.
• Current explanations of schizophrenia emphasize a combination or early trauma, environmental stress, inherited susceptibility, and abnormalities in the brain.
• Environmental factors that increase the risk of schizophrenia include viral infection or malnutrition during the mother’s pregnancy, birth complications, early psychological trauma and a disturbed family environment.
• Heredity is a major factor in schizophrenia.
• Recent biochemical studies have focused on the brain transmitter dopamine and its receptor sites.
• The dominant explanation of schizophrenia, and other problems as well, is the stress vulnerability model.

What are mood disorders? What causes depression?

• Mood disorders primarily involve disturbances of mood or emotion, producing manic or depressive states.
• Long-lasting, though relatively moderate, depression is called a dysthymic disorder. Chronic though moderate swings in mod between depression and elation are called a cyclothymic disorder. Reactive depressions are triggered by external events.
• Bipolar disorders combine mania and depression. In a bipolar I disorder the person alternates between mania and depression. In a bipolar II disorder, the person is mostly depressed, but also has periods of mild mania.
• The problem known as major depressive disorder involves extreme sadness and despondency but no evidence of mania.
• A major mood disorder accompanied by psychotic symptoms is called an affective psychosis.
• Seasonal affective disorder (SAD) which occurs during the winter months, is another common form of depression. SAD is typically treated with phototherapy.
• Biological, psychoanalytic, cognitive, and behavioral theories of depression have been proposed. Heredity is clearly a factor in susceptibility to mood disorders. Research on the causes and treatment of depression continues.

Why do people commit suicide? Can suicide be prevented?

• Suicide is statistically related to such factors as age, sex, and marital status.
• In individual cases, the potential for suicide is best identified by a desire to escape, unbearable psychological pain, frustrated psychological needs, and a constriction of options.
• Suicide can often be prevented by the efforts of family, friends, and mental health professionals.

What does it mean to be ‘crazy’? What should be done about it?

• In Western law, the insanity defense evolved from the McNaghten rule.
• Insanity is closely related to claims of diminished capacity or claims that a person had an irresistible impulse.
• Inconsistencies in the application of the insanity defense have fueled debate about its validity.
• Thomas Szasz has raised questions about the nature of abnormal behavior and its relationship to personal responsibility and civil rights.
• Public policies concerning treatment of the chronically mentally ill continue to evolve as authorities try to strike a balance between providing help and taking away personal freedoms.

TREATMENT OF PSYCHOLOGICAL DISORDERS

Mental illnesses are brought on by a variety of causes therefore therapists must use a variety of methods to treat them.

Research shows that about two-thirds of adults who undergo psychotherapy show marked improvement or recover however about the same number improve without treatment also.

PSYCHODYNAMIC APPROACHES

- also known as insight therapies, based on Freud’s ideas

- goal is to uncover the material in the unconscious mind

- psychoanalysis

- hypnosis

- free association

- dream analysis

- symptom substitution

- transference

HUMANISTIC THERAPY

- emphasize peoples’ positive capacities, ability to self-actualize

- Carl Rogers, client-centered therapy, Unconditional positive regard

- Gestalt therapy

- Existential therapies

COGNITIVE THERAPY

- attempts to directly manipulate the client’s thinking and reasoning processes

- Rational-emotive therapy

- Attributional style

- Beck cognitive triad

GROUP THERAPY

- family therapy

- encounter groups

- self-help groups

SOMATIC THERAPY

- The most common somatic therapy is drug therapy or psychopharmacology

- electroconvulsive therapy, shock treatment

- psychosurgery

How do psychotherapies differ? How did psychotherapy originate?

• Psychotherapies may be classified as insight, action, directive, nondirective, or supportive therapies, and combinations of these.
• Therapies may be conducted either individually or in groups, and they may be time limited.
• Primitive approaches to mental illness were often based on belief in supernatural forces.
• Trepanning involved boring a how in the skull.
• Demonology attributed mental disturbance to demonic possession and prescribed exorcism as the cure.
• In some instances, the actual cause of bizarre behavior may have been ergot poisoning.
• More humane treatment began in 1793 with the work of Philippe Pinel in Paris.

Is Freudian psychoanalysis still used?

• Freud’s psychoanalysis was the first formal psychotherapy. Psychoanalysis seeks to release repressed thoughts and emotions from the unconscious.
• The psychoanalyst uses free association, dream analysis, and analysis of resistance and transference to reveal health-producing insights.
• Some critics argue that traditional psychoanalysis receives credit for spontaneous remissions of symptoms. However, psychoanalysis has been shown to be successful for many patients.
• Brief psychodynamic therapy (which relies on psychoanalytic theory but is brief and focused) is as effective as other major therapies.

What are the major humanistic therapies?

• Client-centered (or person-centered) therapy is nondirective and is dedicated to creating an atmosphere of growth.
• Unconditional positive regard, empathy, authenticity, and reflection are combined to give the client a chance to solve his or her own problems.
• Existential therapies, such as Frankl’s logotherapy, focus on the end result of the choices one makes in life. Clients are encouraged through confrontation and encounter to exercise free will and to take responsibility for their choices.
• Gestalt therapy emphasizes immediate awareness of thought and feelings. Its goal is to rebuild thinking, feeling, and acting into connected wholes and to help clients break through emotional blockages.
• Media psychologists, telephone counselors, and cybertherapists may, on occasion, do some good. However each has serious drawbacks, and the effectiveness of telephone counseling and cybertherapy has not been established.
• Therapy by videoconferencing shows more promise as a way to provide mental health services at a distance.

What is behavior therapy?

• Behavior therapists use various behavior modification techniques that apply learning principles to change human behavior.
• In aversion therapy, classical conditioning is used to associate maladaptive behavior (such as smoking or drinking) with pain or other aversive events in order to inhibit undesirable responses.

How is behavior therapy used to treat phobias, fears, and anxieties?

• Classical conditioning also underlies systematic desensitization, a technique used to overcome fears and anxieties. In desensitization, gradual adaptation and reciprocal inhibition break the link between fear and particular situations.
• Typical steps in desensitization are: Construct a fear hierarchy, learn to produce total relaxation, and perform items on the hierarchy (from least to most disturbing).
• Desensitization may be carried out with real settings, or it may be done by vividly imagining the fear hierarchy.
• Desensitization is also effective when it is administered vicariously – that is, when clients watch models perform the feared responses.
• In some cases, virtual reality exposure can be used to present fear stimuli in a controlled manner.
• A new technique called eye movement desensitization and reprocessing (EMDR) shows promise as a treatment for traumatic memories and stress disorders. At present, however, EMDR is highly controversial.

What role does reinforcement play in behavior therapy?

• Behavior modification also makes use of operant principles, such as positive reinforcement, nonreinforcement, extinction, punishment, shaping, stimulus control, and time out. These principles are used to extinguish undesirable responses and to promote constructive behavior.
• Nonreward can extinguish troublesome behaviors. Often this is done by simply identifying and eliminating rein forcers, particularly attention and approval.
• To apply positive reinforcement and operant shaping, symbolic rewards known as tokens are often used. Tokens allow immediate reinforcement of selected target behaviors.
• Full-scale use of tokens in an institutional setting produces a token economy. Toward the end of a token economy program, patients are shifted to social rewards such as recognition and approval.

Can therapy change thoughts and emotions?

• Cognitive therapy emphasizes changing thought patterns that underlie emotional or behavioral problems. Its goals are to correct distorted thinking and/or teach improved coping skills.
• In a variation of cognitive therapy called rational-emotive behavior therapy (REBT), clients learn to recognize and challenge their own irrational beliefs.

Can psychotherapy be done with groups of people?

• Group therapy may be a simple extension of individual methods, or it may be based on techniques developed specifically for groups
• In psychodrama, individuals enact roles and incidents resembling their real-life problems. In family therapy, the family group is treated as a unit.
• Although they are not literally psychotherapies, sensitivity and encounter groups attempt to encourage positive personality change. In recent years, commercially offered large-group awareness trainings have become popular. However, the therapeutic benefits of such programs are questionable.

What do various therapies have in common?

• To alleviate personal problems, all psychotherapies offer a caring relationship, emotional rapport, a protected setting, catharsis, explanations for the client’s problems, a new perspective, and a chance to practice new behaviors.
• Many basic counseling skills underlie a variety of therapies. These include listening actively, helping to clarify the problem, focusing on feelings, avoiding the giving of unwanted advice, accepting the person’s perspective, reflecting thoughts and feelings, being patient during silences, using open questions when possible, and maintaining confidentiality.

How do psychiatrists treat psychological disorders?

• Three medical, or somatic, approaches to treatment are pharmacotherapy, electroconvulsive therapy (ECT), and psychosurgery. All three techniques are controversial to a degree because of questions about effectiveness, and side effects.
• Community mental health centers seek to avoid or minimize mental hospitalization. They also seek to prevent mental health problems through education, consultation, and crisis intervention.

How are behavioral principles applied to everyday problems?

• Cognitive techniques can be an aid to managing personal behavior.
• In covert sensitization, aversive images are used to discourage unwanted behavior.
• Thought stopping uses mild punishment to prevent upsetting thoughts.
• Covert reinforcement is a way to encourage desired responses by mental rehearsal.
• Desensitization pairs relaxation with a hierarchy of upsetting images in order to lessen fears.

How could a person find professional help?

• In most communities, a competent and reputable therapist can be located with public sources of information or through a referral.
• Practical considerations such as cost and qualifications enter into choosing a therapist. However, the therapist’s personal characteristics are of equal importance.

Do cultural differences affect counseling and psychotherapy?

• Many cultural barriers to effective counseling and therapy have been identified.
• Aware therapists are beginning to seek out the knowledge and skills needed to intervene successfully in the lives of clients from diverse cultural backgrounds.
• The culturally skilled counselor must be able to establish rapport with a person from a different cultural background and adapt traditional theories and techniques to meet the needs of clients from non-European ethnic or racial groups.

SOCIAL PSYCHOLOGY

-The scientific study of the ways in which the thoughts, feelings, and behaviors of one individual are influenced by the real, imagined, or inferred behavior or characteristics of other people.

SOCIAL PSYCHOLOGY

How does group membership affect individual behavior?

• Humans are social animals enmeshed in a complex network of social relationships. Social psychology studies how individuals behave, think, and feel in social situations.
• Culture provides a broad social context for our behavior. One’s position in groups defines a variety of roles to be played.
• Social roles, which may be achieved or ascribed, are particular behavior patterns associated with social positions. When two or more contradictory roles are held, role conflict may occur. The Stanford prison experiment showed that destructive roles may override individual motives for behavior.
• Positions within groups typically carry higher or lower levels of status. High status is associated with special privileges and respect.
• Group structure refers to the organization of roles, communication pathways, and power within a group. Group cohesiveness is basically the degree of attraction among group members.
• Norms are standards of conduct enforced (formally or informally) by groups. The autokinetic effect has been used to demonstrate that norms rapidly form even in temporary groups.

What unspoken rules govern the use of personal space?

• The study of personal space is called proxemics. Four basic spatial zones around each person’s body are intimate distance (0 to 18 inches), personal distance (1 ½ to 4 feet), social distance (4 to 12 feet), and public distance (12 feet or more).

How do we perceive the motives of others and the causes of our own behavior?

• Attribution theory is concerned with how we make inferences about behavior. A variety of factors affect attribution, including consistency, distinctiveness, situational demands, and consensus.
• The fundamental attributional error is to ascribe the actions of others to internal causes. Because of actor-observer differences, we tend to attribute our own behavior to external causes.
• Self-handicapping, involves arranging excuses for poor performance as a way to protect one’s self-image or self-esteem.

Why do people affiliate?

• The need to affiliate is tied to additional needs for approval, support, friendship, and information. Additionally, research indicates that affiliation is related to reducing anxiety and uncertainty.
• Social comparison theory holds that we affiliate to evaluate our actions, feelings, and abilities. Social comparisons are also made for purposes of self-protection and self-enhancement.

What factors influence interpersonal attraction?

• Interpersonal attraction is increased by physical proximity (nearness), frequent contact, physical attractiveness, competence, and similarity. A large degree of similarity on many dimensions is characteristic of mate selection
• Self-disclosure occurs more when two people like one another. Self-disclosure follows a reciprocity norm: Low levels of self-disclosure are met with low levels in return, whereas moderate self-disclosure elicits more personal replies. However, overdisclosure tends to inhibit self-disclosure by others.
• According to social exchange theory, we tend to maintain relationships that are profitable – that is, those for which perceived rewards exceed perceived costs.
• Romantic love has been studied as a special kind of attitude. Love can be distinguished from liking by the use of attitude scales. Dating couples like and love their partners but only like their friends. Love is also associated with greater mutual absorption between people.
• Adult love relationships tend to mirror patterns of emotional attachment observed in infancy and early childhood. Secure, avoidant, and ambivalent patterns can be defined on the basis of how a person approaches romantic and affectionate relationships with others.
• Evolutionary psychology attributes human mating patterns to the differing reproductive challenges faced by men and women since the dawn of time.

What have social psychologists learned about conformity, social power, obedience, and compliance?

• In general, social influence refers to alterations in behavior brought about by the behavior of others. Conformity to group pressure is a familiar example of social influence
• Virtually everyone conforms to a variety of broad social and cultural norms. Conformity pressures also exist within smaller groups. The famous Asch experiments demonstrated that various group sanctions encourage conformity.
• Groupthink refers to compulsive conformity in group decision making. Victims of groupthink seek to maintain each other’s approval, even at the cost of critical thinking.
• Social influence is also related to five types of social power: reward power, coercive power, legitimate power, referent power, and expert power.
• Obedience to authority has been investigated in a variety of experiments, particularly those by Milgram. Obedience in Milgram’s studies decreased when the victim was in the same room, when the victim and subject were face to face, when the authority figure was absent, and when others refused to obey.
• Compliance with direct requests is another means by which behavior is influenced. Three strategies for inducing compliance are the foot-in-the-door technique, the door-it-the-face approach, and the low-ball technique.
• Recent research suggests that, in addition to excessive obedience to authority, many people show a surprising passive compliance to unreasonable requests.

How does self-assertion differ from aggression?

• Self-assertion, as opposed to aggression, involves clearly stating one’s wants and needs to others. Learning to be assertive is accomplished by role-playing, rehearsing assertive actions, over-learning, and using specific techniques, such is the ‘broken record’.

What is a social trap?

• A social trap is a social situation in which immediately rewarded actions have undesired effects in the long run.
• One prominent social trap occurs when limited public resources are overused, a problem called the tragedy of the commons.
