The 4 functions of behavior
The difference in short
Every behavior serves one of four functions: gaining attention, escaping a demand, accessing something tangible, or automatic stimulation. To identify it, ask what the behavior gets or avoids. Function — not form — determines the intervention.
Quick comparison
| Attention | Escape | Tangible | Automatic | |
|---|---|---|---|---|
| Operation | The behavior gains social attention | Avoids or postpones a demand | Accesses an object or activity | Produces stimulation on its own |
| Effect | Gets others to react | Ends or delays a task | Gets something concrete | Reinforces with no one else |
| Example | He screams and the teacher comes over. | He throws the materials and the task stops. | He cries and is given the toy. | He rocks because the sensation feels good. |
How to tell them apart
- What does the behavior GET or AVOID? Attention (social), escape (from a demand), tangible (object/activity), or automatic (stimulation).
Examples
Attention
He screams and the teacher comes over.
Escape
He throws the materials and the task stops.
Tangible
He cries and is given the toy.
Automatic
He rocks because the sensation feels good.
Frequently asked
Can a behavior have more than one function?
Yes. The same form of behavior can serve different functions in different contexts; that's why a functional assessment is done before intervening.
