Chapter 9: Escape, Avoidance, and Punishment Flashcards
Why do some scientists think escape behavior is easier to understand than avoidance behavior?
It is easy to observe an organism abandon an aversive stimulus for a non-aversive stimulus and environment. With avoidance behavior, it appears as if the organism is leaving a non-aversive stimulus for another non-aversive stimulus.
Negative reinforcement is associated with which two types of behavior?
1) Escape
2) Avoidance
_________ behavior terminates the aversive stimulates while _________ behavior prevents the aversive stimulus.
Escape
avoidance
Behavior that prevents an aversive stimulus from occurring is called ________ behavior.
avoidance
Shuttle Avoidance Procedure
An animal has to shuttle back and forth in a box to avoid an aversive stimulus.
Behavior that terminates an aversive stimulus is called ________ behavior.
escape
In the shuttle avoidance procedure, a rat first learns to ________ from the shock with the ______ acting as the S^d for the behavior. The rat later learns to ______ the shock, with the _________ acting as the S^d for the behavior.
Shock: Cross barrier > Removal of shock
then
Light: Cross barrier > Avoidance of shock
escape
shock
avoid
light
Who founded the Two-Process Theory of Avoidance?
Mowrer
What is the “Two-Process Theory of Avoidance”?
The theory proposes that there are two processes that shapes the behavior.
What are the two-processes in the theory of avoidance?
1) Classical conditioning, in which a fear response is conditioned to be elicited by a CS, and
2) Operant conditioning, in which moving away from the CS is negatively reinforced by a reduction in fear
What are two problems with the “Two-Process Theory of Avoidance”?
1) Avoidance responses are often extremely persistent
2) After repeated avoidance trials, animals appeared to how no evidence of fear but continued to make the avoidance response anyway.
Why do some experts disagree that “avoidance responses are persistent”?
They believe that extinction will eventually occur and cause the behavior to disappear.
One-Process Theory of Avoidance
The act of avoidance is negatively reinforced simply by the lower rate of aversive stimulation with which is associated.
According to the anxiety conservation hypothesis, avoidance responses usually occur so (quickly/slowly) that exposures to the (CS/US) are too (long/brief) for ________ to take place.
quickly
CS
brief
extinction
According to Mineka, a limitation of applying experimental models of avoidance to phobias is that experimental avoidance conditions (more/less) readily than does phobic avoidance.
less
Experimental avoidance often requires (one/a few) conditioning trial(s), while phobic avoidance usually requires (one/a few) conditioning trial(s); additionally, (experimental/phobic) avoidance is less than 100% certain.
a few
one
experimental
A critical aspect of Stampfl’s experimental analogue of phobic conditioning is that the avoidance response can occur (early/late) in the sequence of events leading up to the feared CS, thereby (maximizing/minimizing) the amount of effort involved in making the response.
early
minimizing
Obsessive-Compulsive Disorder (OCD)
A disorder characterized by persistent thoughts, impulses or images and repetitive, stereotyped actions that are carried out in response out the obsessions.
Avoidance responses from phobic conditioning results in (little/considerable) exposure to the feared CS, thereby greatly (increasing/reducing) the likelihood that the fear response will __________.
little
reducing
extinguish
_________ are associated with an increase in anxiety where as ___________ are associated with a decrease in anxiety.
Obsessions
compulsions
In the two-process theory, the anxiety is __________ conditioned and the repairing of the anxiety is ________ conditioned.
classically
operant
What is the difference between OCD and a phobia?
Individuals with OCD will do something to reduce the anxiety and individuals with phobias will not do something to reduce anxiety (avoid).
Exposure-and-Response Prevention (ERP)
A method of treating OCD that involves prolonged exposure to the anxiety-arousing event while not engaging in the compulsive behavior patter that reduces the anxiety.
ERP combines the _________ exposure form flooding and the ________ exposure of systematic desensitization.
prolonged
graduated
How are ERPs typically carried out?
The first exposure with a therapist is generally 90 minutes or more. Clients and patients are then asked to not participate in anxiety-reducing activities and to try exposure therapy at home. Once the obsessive-compulsive pattern is eliminated, normal patterns of behavior can continue.
Selective sensitization can lead to ________ or OCD.
phobias
From the perspective of the two-process theory, the decrease in anxiety likely functions as ________ ________ for the compulsive behavior.
negative reinforcement
People with OCD are usually (able/unable) to recall a particular conditioning event that was the cause of the obsessional anxiety response. The disorder often arises, however, during times of _______. This suggests that a process of ________ may exacerbate normal concerns about cleanliness and safety.
unable
stress
sensitization
People with OCD fail to realize that intrusive thoughts are (common/uncommon) and that such thoughts are (controllable/uncontrollable). They also (take/fail to take) responsibility for highly (probable/improbable) events.
uncommon
uncontrollable
take
improbable
Approach-avoidance conflict
Events that are in some ways rewarding and in some ways punishing.
If you are far from the goal, you are more drawn to the appetitive stimulus. As you move closer to the goal, you are more drawn to the aversive stimulus.
