Learning Your ABC's
It is important to explore the reasons “why” a difficult behaviour may be occurring. In ABA we call this the “function” of the behaviour.
4 Functions of Behaviour
ESCAPE/AVOID something or someone
The behaviour results in the removal or avoidance of something (i.e., situations, tasks, items or people).
Example 1: A child bites his brother every time he comes close to him and his brother quickly moves away. Biting resulted in escaping his brother’s presence.
Example 2: A child screams and cries when he is told to clean his room and so his mother tidies it up for him. Screaming and crying resulted in avoiding cleaning his room.
Get ATTENTION from someone
The behaviour results in a reaction or response from another person.
Example 1: A child cries when his dad is talking to another person and his dad pauses his discussion with the other person and tells his child that he needs to stop crying and that it is embarrassing. Crying resulted in getting dad to talk to him.
Example 2: A child hits his brother and his brother cries and screams at him. Hitting resulted in his brother displaying the reaction of crying and screaming.
Get something TANGIBLE
The behaviour results in access to a desired “tangible” (i.e., an item or activity)
Example 1: A child sees a chocolate bar in the store and grabs it off the shelf and opens it. His grandma buys the chocolate bar because it is open and gives it to him. Grabbing and opening the chocolate bar resulted in him getting the chocolate bar.
Example 2: A child stomps his feet and yells “I want my iPad” and his mom, who is on the phone, gives him the iPad. Screaming for the iPad resulted in her getting the ipad.
Access a SENSORY feeling
A behaviour results in a pleasurable internal feeling. Often this is described as an “automatic” function. In these situations, there are no external responses or environmental reactions as a response to the behaviour.
Example 1: A child jumps up and down and flaps her hands when she is alone in her room or when she is playing a preferred game. It may be assumed that jumping and hand flapping resulted in some pleasurable internal feeling.
Example 2: A child repeatedly picks his finger nails repeatedly throughout the day regardless of the activity he is engaged in. Nobody responds to the behaviour but it continues. It may be assumed that picking fingers resulted in some pleasurable internal feeling.
ABCs of Behaviour
A way to determine some of the reasons why a behaviour might be occurring is to use the ABC Model. This will help you examine the difficult behaviour, the triggers behind it and the impact the behaviour has on the child’s environment (essentially, what the behaviour results in).
ABC Stands for:
Antecedent
An Antecedent is anything that “triggers” the behaviour. Essentially this is any event, activity, action, etc. that occurs immediately before the behaviour is observed. It is very important to keep any personal opinions or thoughts aside when thinking about antecedents. Sometimes our personal opinions make us think a behaviour is happening for one reason, when really it is happening for another reason.
Adapted from: Cooper, Heron & Heward (2007); Buckley (2019)Examples of Antecedents:
Someone standing near the individual
A preferred item is taken away
Someone says “No” to a request
A movie the individual is watching ends
A direction is given to the individual
Someone asks the individual a question
Something in the individuals current environment changes or is altered
Preferred items are not available
No attention is being provided to the individual
Behaviour
Behaviour is anything that a living being can do. Behaviour is not necessarily something aversive or “bad” (e.g., waving at another person is a behaviour). For the purpose of problem solving difficult behaviour, the term “behaviour” is the actions or sounds that the individual is engaging in. Behaviour has to be observable and it has to be something that, if needed, can be measured.
Adapted from: Cooper, Heron & Heward (2007); Buckley (2019)Examples of Difficult Behaviour:
Spitting towards another person’s face
Hitting a sibling
Biting one’s own arm
Throwing an item onto the ground
Saying a swear word
Pinching someone’s face
Crying
Screaming
Pulling the dog’s fur
Running away from a person
It is best to describe the behaviour exactly as it is seen or observed. Example: “Bobby hit his brother in the face with a closed fist” instead of “Bobby was so angry he started to go after his brother”
Consequence
A Consequence is the “outcome” of the behaviour. Often people think of a consequence as something “negative” or “unpreferred”. A consequence can be any reaction, response, or event that happens immediately after the behaviour occurs. The consequence will determine whether or not the individual will engage in the behaviour again in the future. Sometimes the way we respond acts as a reinforcer. If the behaviour “gets” access to what the individual is seeking through behaviour, it will be reinforced and will occur again. It is important to be careful as sometimes a consequence we think will be aversive or a deterrent ends up reinforcing a behaviour.
Adapted from: Cooper, Heron & Heward (2007); Buckley (2019)Examples of Consequences:
Someone saying “No” when an individual hits someone
Giving an individual a toy when they grab at it
Giving an individual a “timeout”
Yelling in response to a difficult behaviour
Removal of a preferred item or activity
Hugging an individual when they are crying
Removal of homework tasks when an individual complains
It can be helpful to write ABC’s down so that patterns can be observed. It is difficult to determine why a behaviour may be happening based on one situation. Recording things over a few situations, even days if it is safe to do so, can be helpful in understanding why the person is engaging in the behaviour.
Recording Antecedents, Behaviours and Consequences on an ABC form will allow you to review what happened and think about things at an alternate time (when things are calm and safe to do so).

What to Do I Do Next
Use the information you have gathered or considered to determine “why” your child is engaging in the difficult behaviour. In other words, think about the function.
Consider:
What are some common triggers?
What is my child “getting” by engaging in the challenging behaviour?
Does the behaviour “work” for my child?
What are some of the common responses to the behaviour?
Is my child’s behaviour an attempt to get something they want, avoid or escape something aversive for them, gain attention or a reaction from someone, or because they feel something internal as a result of engaging in the behaviour
After you have done some problem solving around the behaviour, it is time to put some strategies into place to try and reduce the likelihood the behaviour will occur. These are considered “proactive strategies”. It is also important to respond less to the difficult behaviour and more to appropriate and functional behaviour.
