What is extinction?

Extinction is the process in which a previously reinforced behavior is no longer followed by the reinforcing consequences. It is not a punishment procedure.

Extinction provides zero _____

Probability of reinforcement.

Extinction does not require application of

a punisher

Example of behavior maintained by poisitve reinforcement

Hitting self=attention from parent
Intervention= The R+ is no longer provided..behavior decreases.

Example of behavior maintained by negative reinforcement

hitting self= espcape from chores.
Intervention= removal of the aversive stimulus no longer occures for innapropriate behavior- behavior decreases

Example of behavior maintained by auto R+

Hitting self = auto R+...intervention- dampen or removing sensory consquence. wearing helmet

Extinction burst is...

When a behavior is no longer reinforced, the behavior temporarily increases in frequency, duration, or intensity before decreasing. Novel resoponses may also occur.

Spontaneous recovery is..

The reapperance of a behavior after it was decreased through extinction

Using extinction properly means...

Withold all reinforcers mainting the problem behavior, withold reinforcement consistently , combine extinction with other procedures (dro and dro), include signficant others in intervention, use instructions.

When to not use extinction..

Sevre behaviors


The process in which a behavior is weakend by the immediate consquence that follows its occurance.
Punisher- the consequence which weakens an operant behavior.

Positive punishment-

Occurs when an aversive stimulus is presented immeditaely following the occurence of a behavior and results ina decrease in future occurrences of the behavior.

Negative punishment-

Negative punishment involves the termination or removal of an already present stimulus immediately following the occurence of a behavior that results in a decrease in the future frequency of that behavior ie. response cost

What influences the effectiveness of a potential punisher?

Immediacy, MO's

Positive punishment procedures-

Overcorrection, contingent exercise, response blocking


The student is required to engage in an effortful behavior for an extended period contingent on each instance of the problematic behavior.
1. positive practice- practice correct forms of behavior
2. resistution- must restore environment

Reinforcement procedures should always be used in conjuction with..
