Module 4 Flashcards
extinction used when behavior is maintained by positive reinforcement
May involve…
witholding a consequence stimulus
extinction used if behavior is maintained by negative reinforcement
escape extinction
escape extinction
not removing an antecedent aversive stimulus
Skip scratches his arm until it bleeds. His treatment team puts a soft pad on his arm to protect his skin. Now he scratches the pad, w/o injuring himself. Is this an example of extinction?
Yes, it’s called sensory extinction
prevents the feeling of the scratching that was maintaining the behavior
Side effects of extinction(2)
there may be
- extinction burst
- other behaviors, especially emotions responses, agression or behaviors from long ago
Extinction and the RBT (4)
- it will be used in combo w/other behavior building procedures
- follow plan closely
- be prepared for extinction bursst
- be careful not to reinforce during extinction burst
Punishment
is an environmental change that:
follows a response and decreases the future frequency of that behavior
Punishment is defined by
its effect on the specific bheavior it follows, not by what it looks like (topography)
Punishment can be
- positive
- negative
Positive punishment
- a consequence
- specific stimulus is presented (added) or magnified
- as a result that type of response is less likely to happen again
what is the stimulus to positive punishment
positive punisher
appetitive
term in ABA for something pleasant
appetitive conditions and reinforcement
if it follows a response (consequence), it may be reinforcing
appetitive conditions and punishment
if it is removed following a response, it may be punishing
negative punishment
-specific stimulus is removed (terminated) or lessened
result of negative punishment
that type of response is less likely to happen again in the future
the stimulus for negative punishment
negative punisher
for negative punishment to occur…
the behaver has to have something to lose that they want to keep
Punishment and the RBT (4)
- punishment ONLY decreases behavior, that is its primary effect
- punishment has side effects
- must be used with caution
- requires significant prior approval and close oversight
Punishment can be (3)
- positive or negative
- socially mediated or automatic
- unconditioned or conditioned
antecedent
what happens in the environment immediately before the behavior
points to remember with antecedents (2)
- the behaver experiences OTHER ppls behavior as stimuli
- thus a response done by someone else can be an antecedent
precursors
responses by the behavior occurring just before the target response
evoke
an antecedent stimulus that makes a behavior more likely to happen
abate
an antecedent stimulus that makes a bheavior less likely to happen
