The function of a behavior is the purpose it serves, meaning what the person gets or avoids as a result of it.
Example
A learner hits whenever work is presented, and the work is then removed. The likely function is escape. A learner who calls out when the adult looks away, and gets attention, is likely maintained by attention.
Key points
- Attention: the behavior gets social attention.
- Escape: the behavior removes or avoids a task or situation.
- Tangible: the behavior gets an item or activity.
- Automatic: the behavior produces its own sensory result and does not depend on other people.
Exam tip
The same-looking behavior can have different functions, so treatment follows the function, not the look of the behavior.
Common mistake
Guessing the function from how the behavior looks. Two identical behaviors can serve different functions, so use data.
Quick check
Which function is a child’s screaming that stops when a task is removed? Escape.
