Ch. 4 Flashcards
1
Q
Acquisition
A
- the process of developing and strengthening a conditioned response through repeated pairings of a CS with a US
2
Q
asymptote of conditioning
A
- the maximum amount of conditioning that can take place in a particular situation
- ex. hits a plateau
3
Q
Extinction
A
- CR is weakened or eliminated when the CS is repeatedly presented in the absence of the US
- ex. if we stop pairing the metronome with food, it will eventually go back to being a NS
- ex. exposure therapy to phobias
4
Q
is extinction final?
A
no, if a CR weakens/goes away, if you bring the CS back in, it may take only a few trials to bring it back the second time
5
Q
Spontaneous recovery
A
- the reappearance of a CR to a CS following a rest period after extinction
- each time it is recovered, the conditioning is typically weaker than the time before
6
Q
Disinhibition
A
- sudden recovery of a CR during an extinction procedure when a novel (unfamiliar) stimulus is introduced
- ex. anxiety fades while you’re giving a speech but randomly comes back after a random loud noise
- similar to dishabituation
7
Q
stimulus generalization
A
- tendency for a CR to occur in the presence of a stimulus that is similar to the CS
- ex. will still salivate to any tone but will salivate MORE to the tones that are closest to the OG tone
- when stimuli are physically similar and vary along a continuum (ex. tone)
8
Q
semantic generalization
A
- the generalization of a conditioned response to verbal stimuli that are similar in meaning to the CS
9
Q
stimulus discrimination
A
- the tendency for a response to be elicited more by one stimulus than another
- ex. only salivates to the exact tone
- can be trained by presenting one tone, food, another tone, no food (1 trial)
- helps study sensory capacities
