BCBA Test Content Outline (6th ed.)
B.1: What is behavior, response and response class?
Behavior: What living organisms say or do; implying an action and even a thought, feel, or what they are saying
(THINK ABOUT THE DEAD MANS TEST, MENTALISM TEST, & OPERATIONAL DEFINITION TEST)
Response: a single instance of a behavior (ex. behavior is hand flapping and the response is client hand flapped one time)
Response Class: a group of behaviors that result in the same function (note: responses in the same response class can look different)
Skill acquisition programs in Applied Behavior Analysis (ABA) are designed to help individuals gain essential skills that improve their independence, communication, and overall quality of life. To be truly effective, these programs must be individualized, ethically sound, and rooted in evidence-based practices.
Before teaching begins, a behavior analyst conducts assessments to identify a learner’s current abilities and areas where support is needed. These assessments might include direct observation, interviews, preference assessments, or standardized tools.
Based on the results, measurable and observable goals are created. Goals must be relevant to the individual and focused on increasing socially significant behaviors, such as communication, daily living skills, or social interactions.
A variety of instructional methods may be used, depending on the learner’s needs:
Discrete Trial Training (DTT): A structured teaching method that uses repeated trials and clear reinforcement.
Natural Environment Teaching (NET): Learning is embedded in everyday activities and driven by the learner’s motivation.
Task Analysis: Breaking down a complex skill (e.g., brushing teeth) into smaller, teachable steps.
Chaining: Teaching steps of a task in sequence using forward, backward, or total task chaining.
Prompting and Fading: Providing assistance to ensure correct responses and gradually reducing that support to encourage independence.
Each strategy is selected based on its appropriateness for the specific goal and the learner’s profile.
Every skill acquisition plan includes a data collection method. Depending on the goal, this may involve frequency counts, duration, latency, or percent correct.
Data is reviewed regularly to evaluate effectiveness, make informed decisions, and modify interventions. Visual analysis of graphed data helps determine when a skill is mastered or additional support is required.
A critical component of any skill acquisition plan is ensuring that the skill transfers to real-world situations. Behavior analysts create opportunities for the learner to:
Use the skill with different people
Perform the skill in various settings
Apply the skill across different materials or tasks
Maintenance strategies are also implemented so that skills do not fade after direct teaching ends.
Ethical responsibility is central to skill acquisition. Behavior analysts must:
Choose goals that are in the best interest of the learner (BACB Code 2.09)
Use the least intrusive, most effective teaching methods
Avoid using reinforcers that may cause harm (Code 4.08)
Ensure that teaching respects the learner’s dignity and autonomy
The overall goal is to teach meaningful skills in a respectful, person-centered manner that is grounded in scientific principles.

Behavioral Brains & Verbal Gains: Cracking the Code of Conceptual Mastery
This section includes 24 key objectives (B.1–B.24) covering foundational concepts in behavior analysis such as reinforcement and punishment contingencies, schedules of reinforcement, stimulus control, verbal operants, motivating operations, and more. For each item, I provided:
A brief 1–2 sentence summary explaining the concept in clear, accessible language
A direct link to a high-quality study resource or article (e.g., AllDayABA, Learning Behavior Analysis, Quizlet)
Coverage of both fundamental principles (like operant conditioning) and advanced concepts (like behavioral momentum and matching law)
B.1. Identify and distinguish among behavior, response, and response class.
Summary:
Behavior refers to any observable and measurable action. A response is a specific instance of behavior, and a response class is a group of responses that serve the same function.
Resource:
Quizlet Flashcards on Behavior, Response, and Response ClassQuizlet+1Stuvia+1
B.2. Identify and distinguish between stimulus and stimulus class.
Summary:
A stimulus is any event or object that can influence behavior. A stimulus class is a group of stimuli that share common elements and have the same effect on behavior.
Resource:
Learning Behavior Analysis: Stimulus and Stimulus ClassLearning Behavior Analysis, LLC
B.3. Identify and distinguish between respondent and operant conditioning.
Summary:
Respondent conditioning involves automatic responses to stimuli (e.g., Pavlov's dogs salivating to a bell), while operant conditioning involves behaviors influenced by consequences (reinforcements or punishments).
Resource:
AllDayABA: Respondent vs. Operant ConditioningAllDayABA+1Pinterest+1
B.4. Identify and distinguish between positive and negative reinforcement contingencies.
Summary:
Positive reinforcement adds a stimulus to increase behavior (e.g., giving a treat), while negative reinforcement removes an aversive stimulus to increase behavior (e.g., turning off a loud noise).
Resource:
Quizlet Flashcards on ReinforcementQuizlet+1Stuvia+1
B.5. Identify and distinguish between positive and negative punishment contingencies.
Summary:
Positive punishment introduces an aversive stimulus to decrease behavior (e.g., adding chores), while negative punishment removes a desired stimulus to decrease behavior (e.g., taking away a toy).
Resource:
Learning Behavior Analysis: Punishment ContingenciesLearning Behavior Analysis, LLC
B.6. Identify and distinguish between automatic and socially mediated contingencies.
Summary:
Automatic contingencies occur without social mediation (e.g., scratching an itch), while socially mediated contingenciesinvolve another person delivering the consequence (e.g., teacher giving praise).
Resource:
AllDayABA: Automatic vs. Socially MediatedAllDayABA+1Pinterest+1
B.7. Identify and distinguish among unconditioned, conditioned, and generalized reinforcers.
Summary:
Unconditioned reinforcers are naturally reinforcing (e.g., food), conditioned reinforcers acquire value through association (e.g., money), and generalized reinforcers are conditioned reinforcers paired with many other reinforcers (e.g., tokens).
Resource:

B.8. Identify and distinguish among unconditioned, conditioned, and generalized punishers.
Summary:
Unconditioned punishers naturally decrease behavior (e.g., pain), conditioned punishers acquire their effect through association (e.g., reprimands), and generalized punishers are conditioned punishers linked to multiple other punishers (e.g., a disapproving look).
Resource:
Learning Behavior Analysis: Types of Punishers
B.9. Identify and distinguish among simple schedules of reinforcement.
Summary:
Simple schedules include fixed ratio, variable ratio, fixed interval, and variable interval schedules, each defining how and when reinforcement is delivered.
Resource:
Helpful Professor: Reinforcement Schedule ExamplesHelpful Professor
B.10. Identify and distinguish among concurrent, multiple, mixed, and chained schedules of reinforcement.
Summary:
These are compound schedules involving combinations of simple schedules. For example, concurrent schedules involve two or more schedules operating simultaneously, while chained schedules require a sequence of responses.
Resource:
Learning Behavior Analysis: Compound SchedulesLearning Behavior Analysis, LLC
B.11. Identify and distinguish between operant and respondent extinction as operations and processes.
Summary:
Operant extinction involves withholding reinforcement for a previously reinforced behavior, leading to its decrease. Respondent extinction involves the repeated presentation of a conditioned stimulus without the unconditioned stimulus, weakening the conditioned response.
Resource:
AllDayABA: Extinction ProcessesAllDayABA+1Pinterest+1
B.12. Identify examples of stimulus control.
Summary:
Stimulus control occurs when a behavior is more likely to occur in the presence of a specific stimulus due to a history of reinforcement.
Resource:
Learning Behavior Analysis: Stimulus Control
B.13. Identify examples of stimulus discrimination.
Summary:
Stimulus discrimination involves responding differently to various stimuli based on which ones have been associated with reinforcement.
Resource:
AllDayABA: Stimulus Discrimination
B.14. Identify and distinguish between stimulus and response generalization.
Summary:
Stimulus generalization occurs when a behavior is elicited by stimuli similar to the original stimulus. Response generalization happens when different responses produce the same effect.
Resource:

B.15. Identify examples of response maintenance.
Summary:
Response maintenance refers to the continued performance of a behavior after reinforcement has been withdrawn.
Resource:
Learning Behavior Analysis: Response Maintenance
B.16. Identify examples of motivating operations.
Summary:
Motivating operations are environmental events that alter the effectiveness of a reinforcer and change the frequency of behavior associated with that reinforcer.
Resource:
AllDayABA: Motivating Operations
B.17. Distinguish between motivating operations and stimulus control.
Summary:
While both influence behavior, motivating operations affect the value of a reinforcer, whereas stimulus control involves the presence of a stimulus signaling the availability of reinforcement.
Resource:
Learning Behavior Analysis: MO vs. Stimulus ControlLearning Behavior Analysis, LLC
B.18. Identify and distinguish between rule-governed and contingency-shaped behavior.
Summary:
Rule-governed behavior is controlled by verbal statements about contingencies, while immediate consequences directly influence contingency-shaped behavior.
Resource:
AllDayABA: Rule-Governed vs. Contingency-ShapedAllDayABA+1Pinterest+1
B.19. Identify and distinguish among verbal operants.
Summary:
Verbal operants are functional units of language defined by their antecedents and consequences. The primary verbal operants include:BehaviorPREP
Mand: A request controlled by a motivating operation and reinforced by a specific consequence.
Tact: Labeling or describing the environment, evoked by a nonverbal stimulus and reinforced socially.
