Extinction
- extinction is confused as being the same as punishment(extinction procedures withhold reinforcement from a previously reinforced/ punishement is any change in stimuli that decreases the future frequency of behavior
- withholding reinforcement form a previoulsy reinforced to decrease its occurrence in the future or completely eliminate it.
-all stakeholders must know that with extinction, there is an initial spike in behaviors due to an extinction burst before the behaviors reduce.
- It provides zero possibility of reinforcement and is often used with differential reinforcement
- withholding reinforcement would be to block access to the tangible item.
- lead to an increase in frequency, duration and magnitude of problem of bx
- fixed ratio schedules of reinforcement are least resistant to extinction.
- intermittent schedules of reinforcement is most resistant to extinction.
Extinction Burst (초반에 behavior가 줄어 들다가 갑자기 다시 오르는것)
- initially there is an sharp increase behaviors but after the burst, the bx decreases to the point of extinction.
- is expected to occur at the beginning of an extinction procedure
Spontaneous Recovery(behavior가 완전히 없어졌다가 갑자기 한번 spike하는것)
- occurs during the implementation of extinction procedures, it involves the short-lived and limited reemergence of the previoyly reinforced problem bx after it has been extinguished even though it no longer produces reinforcement.
Planned ignoring
- the removal of socail reinforcement for a limited time.
- It is only an effective extinction procedure if the fucntions of attention is the maintaining function, if the function was comething else it will not be effective.
Resistance to Extinction
- example, girl calls and texts to ex-boy friend to get back together but ex-boy friend has new girl friend so he never responded to ex-girl frend. However, ex-girl friend keeps texting or calls -> it is resistance to extinction.
Main principles in ABA
- punishment, extinction and reinforcement.
