Final Flashcards
three term contingency
instrumental response (R) occurs in the presence of distinctive stimuli (S) and results in the delivery of the outcome
S: environmental stimuli signaling (R-O)
R: behavior producing the outcome
O: outcome, either appetitive or aversive
S-R association
the discriminative stimulus can become directly associated with the response
key to instrumental learning
S-O association
discriminative stimulus can be associated with the outcome
R-O association
response becomes associated with the outcome
law of effect
responses that produce a satisfying effect in a particular situation become more likely to occur again in that situation
Hull’s theory
reduction of drives is primary force behind motivation
two-process theory
assumes CC mediates instrumental behavior through conditioning of positive or negative emotions depending on emotional valence or reinforcer
premack/differential probability principle
person will perform a less desirable activity to get to a more desirable activity
stimulus control
situations in which a behavior is triggered by the presence or absence of some stimulus
stimulus discrimination
differential responding to two stimuli indicates that pigeons were treating each stimulus differently
stimulus generalization
similar response to two or more stimuli
stimulus generalization gradient
graph showing how the strength of response changes with similarity
sensory capacity
sets a limit on what stimuli can control behavior
sensory orientation
variable that determines whether a particular stimulus feature controls responding
overshadowing
stimuli that get more attention and work as better cues can overshadow other cues in the situation
configural-cue approach
configural info about the entire compound enters into an association with the US
stimulus elements
treating simultaneous presentation of light and tone as conducting of separate visual and auditory cues
configural cues
assumes organisms treat a compound stimulus as an integral whole and not divided into parts/elements
stimulus discrimination training
bringing behavior under stimulus control
stimulus discrimination procedure
establishes control by stimuli that signal when reinforcement is/is not available
discriminative stimuli
once S+ and S- have gained control over behavior, S+ is discriminative stimulus for performing instrumental response and S- is discriminative stimulus for not performing the response
peak-shift effect
shift of the peak of the generalization gradient away from the original S+
