learning Flashcards
contiguity
closeness in time between the pairing of NS and US
Acquisition
phase when NS and US are presented together
Stimulus generalisation
response to a stimulus similar to original CS
Stimulus discrimination
capacity to distinguish between similar but distinct stimuli
Extinction
presentation of CS without US leads to reduction of CR
CS loses its power to elicit a CR
Spontaneous recovery
reappearance of learnt response after extinction has occurred
Higher order conditioning
a strong CS is paired with a NS
new NS becomes a CS
Vicarious classical conditioning
learning to respond emotionally to a stimulus y observing another person’s response to the stimulus
survival value
aversive learning
associating a specific sensory cue with becoming sick
avoiding that sensory cue in future
biological preparedness
tendency of animals to learn certain associations with only one or a few pairings due to survival value of learning
shaping
reinforcement of simple steps leading to the desired behaviour
successive approximation
small steps, one after another, leading to a particular goal behaviour
instinctive drift
the tendency for animal’s behaviour to revert to genetically controlled patterns
reinforcement
an event or stimulus that when following a response increases the possibility that the response will occur again
primary reinforcer
any reinforcer that is naturally reinforcing by meeting a basic biological need
food, drink, pleasure
