25
Sensory preconditioning
Two neutral stimuli are repeatedly paired together without a US. Then, one is paired with a US to become a CS -> the unpaired stimulus then creates a CR response
26
InterTRIAL interval
The gap between successive trials. Affects the rate of conditioning. Intertrial intervals -> longer is better Interstimulus intervals -> shorter is better
27
Four variables that affect the rate of conditioning are:
how the CS and US are paired; CS–US contingency; CS–US contiguity; stimulus features; prior experience with CS and US; number of CS–US pairings; intertrial interval; age; temperament; emotional state/stress.
28
Extinction
Repeated presentation of the CS alone until the CR no longer occurs CS is paired with an absence of the US. Not "forgetting"
29
Spontaneous recovery
The reoccurrence of a CR from an extinguished CS
30
Stimulus Substitution Theory
As per Pavlov, the CS is a substitution for the US. Repeated pairings cause the US-UR neural link to be established between the CS-UR. CS/US stimulate the same area of the brain.
31
According to stimulus substitution theory, the ______ substitutes for the ______.
conditional stimulus (CS) unconditional stimulus (US)
32
Preparatory response theory
Kimble proposed the UR is an innate response that deals with the US, but the CR is a response designed to prepare for the US
33
Kimble
Preparatory response theory
34
Preparatory response theory
Kimble suggested the UR is an innate response for dealing with the US, and the CR merely prepares for the CS
35
Seigel
Compensatory response theory; argued the CR prepares for the US by compensating for it's effects morphine (US) -> ↓ sensitivity to pain (UR) associated stimuli (CS) -> ↑ sensitivity to pain (CR)
36
Lightfoot
Compensatory response theory w/ college students beer 5 days in a row over 30 min. Fifth day = new space. The students in the new place were more drunk Novel setting lacked the other CS, so there was no compensatory CR, and alcohol is more effective
37
Compensatory response theory
Variation of the preparatory response theory - Seigel argues the CR preps for the US by compensation
38
Conditional Awareness theory
Proposes the CR is a result of awareness of the CS-US connection However, conditioning can occur without CS-US contingency awareness
39
Rescorla-Wagner model
There is a limit on the amount of conditioning that can occur with stimuli. Determined by nature of the US (bread vs meat), and maximum learning occurred (e.g., 100 bee stings -> fear doesn't increase)
40
The Rescorla-Wagner model recognizes that the greatest amount of learning occurs in the ______ pairings of CS and US.
first/earliest
41
In trace conditioning, the ______ begins and ends before the ______ appears.
CS US
42
In delay conditioning, the ______ ends only after the ______ begins.
CS US
43
In Pavlovian conditioning, ______ usually refers to the interval between CS and US.
contiguity
44
If one part of a compound stimulus fails to become a CS, ______ has occurred.
overshadowing
45
Wallace & Rosen
Demonstrated that rats have a UR to the odorous chemicals of fox feces. Survival advantage.
46
Watson + Rayner
Little Albert US (noise) -> UR (fear) CS (rat) + US (noise) -> UR (fear) Rat -> Fear
47
Jones
Counterconditioning which grew to exposure therapy Peter, fear of rabbits: CS (rabbit) + positive US (snacks) -> decreased dear. In vivo
48
Systemic Desentitization
Patient + therapist create a list of scenarios from comfortable -> extreme fear. Patient imagines scenarios and therapists conducts relaxation exercise to associate relaxation with the scenario. Scenario (CR) + positive US (relaxation) -> CR (decreased fear) Developed by Wolpe
49
Wolpe
systemic desensitization
50
VRET
virtual reality exposure therapy Rothbaum -> heights, flying Hoffman -> Miss Muppett's spiders
51
Parish
predujice studies; American children towards Vietnamese; could not obtain the same results with blacks.
52
Olsson
paired images with positive or negative words; increased positive feelings toward black americans
53
Aversive therapy
a sexually-arousing CS is followed by a nonsexual US to eliminate the arousal
54
Lavin
therapy w/ crossdressing man. took pics, gave him emetic and showed him pics while an audio tape describing what was happening played. Effective.
55
Maletzsky
treated exhibitionists by pairing CS (imagining exposing) with a US (foul smelling acid). Effective.
56
Garcia
conditioned rats to avoid sweet water using gamma radiation conditioned taste aversion or conditioned food avoidance
57
Conditioned taste aversion+ 2 differences w/ Pavlov
conditioned food avoidance; Garcia 1. CS + US occurs ONCE 2. ISI trial is several minutes Food -> poison can be delayed (Explains long ISI), and can result in death (one trial and done!)
58
Gorn
Paired music with a pen color. American music = preferred the corresponding pen color. Ethnic music = preferred to non-corresponding pen color
59
S**t**uar**t**
**T**oo**t**hpaste: conditioned students to prefer a fictious toothpaste brand by pairing it with positive scenes
60
Gibson
Established in a coke/pepsi experiment that people who strongly favour something are difficult to persuade.
61
Albert became fearful of the rat because the arrival of the rat regularly preceded ______.
loud noise
62
VRET stands for ______ ______ ______ ______ (4).
virtual reality exposure therapy
63
Prejudice is an example of a CER, or ______.
conditional emotional response
64
In the Garcia experiment just described, the CS is______, and the US is______.
saccharin (sugar) radiation
65
Advertisers pair their products with items that arouse ______.
positive emotions
66
Q6. Classical conditioning provides explanations for the basic phenomena of drug addiction, the high, ______ , ______, and______.
tolerance, withdrawal, relapse
67
Classical conditioning appears to be a way of helping to diagnose several medical disorders, one of which is ______.
dementia/ Alzheimer's / deafness/ autism/ OCD
68
The phenomenon of latent __________________ suggests that we are more likely to develop aversions to novel foods than to familiar ones.
inhibition
69
People used to believe that children were instinctively afraid of fire, animals, and many other things. John Watson and Rosalie ___________________ found that many such fears were not innate but were acquired through conditioning.
Rayner
70
The first person to use counterconditioning to treat a phobia was probably _______________________.
Jones (Peter + rabbit + snacks)
71
The work of Staats and Staats suggests that prejudice may be partly the result of ___________________-order conditioning.
higher
72
. Dana Bovbjerg and his colleagues found that women receiving chemotherapy in a hospital later showed decreased functioning of their ____________________ system when they returned to the hospital.
immune
73

music
74
In ______ therapy, a stimulus that elicits an inappropriate response is paired with an aversive stimulus such as shock or an emetic drug.
aversion
75
The pairing of a particular food with nausea-inducing stimuli often results in a conditioned ____________________________.
food avoidance or t**a**st**e** **a**v**e**rsion
