D.1 · Behavior Reduction

Functions of behavior

Compare attention, escape, access to items or activities, and automatic reinforcement through worked examples. Review how an RBT reports patterns for a supervisor’s assessment and follows the assessment conclusions.

Task D.1: Identify common functions of behavior

Useful foundations: C.1: Positive and negative reinforcement

The rule

Behavioral function describes the consequence that maintains a response over time.

Use assessment evidence to distinguish attention, escape, access to items or activities, and automatic reinforcement. An RBT reports patterns and follows the supervisor’s assessment conclusions.

Key terms
Function
The maintaining consequence or effect of a behavior.
Aversive
An event the individual acts to escape or avoid, identified through that person’s behavior.

What to look for

DistinctionLook forHow to decide
AttentionSocial interaction follows behaviorConsider attention as a hypothesis when the pattern supports it.
EscapeA demand or aversive event ends or is postponedLook for what is removed or avoided.
Tangible accessAn item or activity becomes availableIdentify the access that follows the behavior.
Automatic reinforcementThe response itself produces a reinforcing effectEstablish that the response-produced consequence maintains responding across the relevant assessment conditions.

Worked examples

Social consequences

The same call can have different outcomes

In one observation, a learner calls “Hey!” and an adult turns to chat. In another, “Hey!” is followed by the adult returning a tablet. In a third, it is followed by a pause in a difficult task.

Relevant facts

  • The spoken response looks the same.
  • The following events are interaction, item access and task removal.

These events suggest different hypotheses: attention, tangible access and escape.

Same response form → different possible maintaining consequences

Record repeated patterns and relevant context for the supervisor to assess the maintaining relation.

A response-produced effect

The sound comes from the action

In a hypothetical learning demonstration, a person repeatedly rolls a ridged wheel with a fingertip. Rolling directly produces a soft clicking sound. A controlled assessment has established that this response-produced sound maintains the rolling; no other person delivers the sound.

Relevant facts

  • Rolling itself produces the maintaining effect.
  • The scenario supplies an established functional conclusion from assessment.

This illustrates automatic reinforcement: the response directly produces its reinforcing effect.

Wheel rolling → clicking sound produced by rolling itself

Here, rolling directly produces the sound that assessment has established as the reinforcer. When an adult turns on music after a request, another person delivers the consequence. In either arrangement, evidence that the consequence maintains responding establishes its reinforcing function.

What changes the answer?

Keep a loud call; change what the assessment identifies as maintaining it.

  • The call sounds the same in both cases.

Adult conversation maintains the call.

Attention function.

The relevant outcome is social interaction.

Removal of work maintains the call.

Escape function.

The relevant outcome is task removal.

Identify the relation between the response and its maintaining consequence.

Remember

  • Ask what the behavior produces or avoids.
  • Treat a functional hypothesis as a question for assessment.
