learning, behavioral, CBT, memory Flashcards
unconditioned stimulus
the stimulus that naturally elicited salivation
unconditioned response
UR
salivation
conditioned stimulus
neutral stimulus
conditioned response
salivation produced by the conditioned/neutral stimulus
classical conditioning explains ___ human responses
emotional rxns attitudes drug addiction allergies food sexual preferences and aversions psychosomatic disorders
effectiveness of classical conditioning
impacted by:
temporal relationship bt CS and US
*delay conditioning is most efficient (presenting CS so that it precedes and overlaps with US)
number of conditioning trials - the greater the # of trials the stronger and more persistent CR; however, CR is usually weaker in intensity /magnitude than the UR
pre-exposure to the CS or US- slows down acquisition of the CR
classical extintiction
gradual disappearance of CR as the result of repeated presentation of the CS alone
refresher trials are used to avoid this
spontaneous recovery
a CR rarely extinguishes all at once; CR is suppressed rather than eliminated by extinction trials
stimulus generalization
responds with a CR not only to the CS but to other stimuli that are similar
stimulus discrimination
opposite of stimulus generalization- ability to discriminate between the CS and similar stimuli and respond only to the CS with a CR
thru selective reinforcement and extinction
experimental neurosis
produced by very difficult discriminations
restlessness, agitation,
higher order conditioning
when a second neutral stimulus was repeatedly paired with a previously CS, the second neutral stimulus eventually produced a CR
e.g., dog conditioned with tone, and then flashlight presented with tone- now conditioned to flashlight
blocking
once an association has been made bt a CS and US, the presence of the CS blocks an association bt a second neutral stimulus and the US when the CS and the second neutral stimulus are presented together prior to the US
overshadowing
2 neutral stimuli are repeatedly presented together prior to the US
presentation of the 2 stimuli together produce a CR, but when the 2 stimuli are presented separately, only one produces the CR
Watson
classical conditioning - little Albert
counter conditioning
eliminate a maladaptive behavior by pairing a stimulus (CS) associated with that behavior with a stimulus (US) that naturally elicits an incompatible behavior
reciprocal inhibition
counterconditioning
weaken and eliminate anxiety reactions
systematic desensitization
hierarchically arranged anxiety evoking events are paired with relaxation to eliminate anxiety
1) relaxation training
2) construction of anxiety hierarchy
3) desensitization in imagination
4) in vivo desensitization
dismantling strategy
identify mechanisms responsible for benefits of desensitization
*extinction (repeated exposure to the CS without the US) is primary factor responsible for effects of systematic desensitization
in vivo aversion therapy
to treat substance use disorders, paraphiliac, self-injurious behavior
target bx is paired with an aversive stimulus
high relapse and poor generalizability
best when aversion is similar to target behavior
covert sensitization
client imagines engaging in maladaptive behavior and then imagines an aversive stimulus
in vivo exposure with response prevention
exposed to real life anxiety arousing stimuli for prolonged period and prohibited from avoidance or anxiety-reducing response
prolonged (mass) exposure is better than brief exposures
self-directed exposure can be as effective as therapist directed
group = individual treatment; partner assisted works for agoraphobia and OCD
interoceptive exposure (evoking bodily sensations) works for panic
flooding
exposure to most anxiety or fear arousing stimuli for prolonged period
interventions based on CC
systematic desensitization
behavioral sex therapy
in vivo aversion therapy (overt sensitization)
covert sensitization
in vivo exposure with response prevention
implosive therapy
EMDR
Thorndike
study of learning in lower animals would reveal important info about human learning
placing hungry cats in puzzle boxes
instrumental learning - learning is due to connection between response and stimuli as result of trial and error
law of effect
thorndike
response followed by satisfaction will be repeated
neg outcomes have little or no effect
Skinner
complex behaviors are voluntarily emitted as result of the way they operate in the environment = operant conditioning
positive reinforcement
stimulus applied, behavior increases
negative reinforcement
stimulus applied, behavior decreases
negative reinforcement
stimulus removed, behavior increases
negative punishment
stimulus removed, behavior decreases
extinction burst
temporary increase in responding during extinction trials
behavioral contrast
when reinforced for 2 different behaviors and reinforcement for one behavior is withdrawn, the other behavior is likely to increase
generalized secondary reinforcer
secondary reinforcers - acquire value only through repeated association with primary reinforcers (tokens, applause, gold stars)
when secondary reinforcer is paired with several different primary reinforcers (e.g., money)
continuous schedule
rate of acquisition of behavior is fastest - when reinforcement is presented after each response
best way to maintain behavior is to switch to intermittent schedule
intermittent schedules of reinforcement
Fixed interval - reinforcement after fixed amount of time
- low rates of responding
variable interval - interval of time bt reinforcement is unpredictable
-steady but low rate of responding
fixed ratio - reinforcer is delivered each time the subject makes specific # of responses
- high and steady rate of responding
variable ratio - reinforcers are provided after a variable # of responses
- highest rates of responding, most resistant to extinction (slot machine)
