Classical Conditioning Flashcards
Naturally occurring stimulus that leads to reflex
Unconditioned stimulus US (food)
Classical conditioning
Learning based on the conditioning of reflexes
Involuntary response to a unconditioned stimulus
Unconditioned response UR (salivating-unlearned)
Stimulus that causes a learned reflex
Conditioned stimulus CS (bell)
Reflex response to a conditioned response; same or similar to unconditioned response
Conditioned response CR (salivating to bell-learned)
Appetitive conditioning
Learning to predict something that satisfies a desire or appetite (positive event-food)
Aversive conditioning
Learning to avoid or minimize the consequences of an expected aversive event (negative-shock)
Air puff to eye
Unconditioned stimulus
Blinking as a result to air puff
Unconditioned response
Tone before air puff
Conditioned stimulus
Blinking in response to the tone
Conditioned response
Extinction
Previously learned association is weakened by repeatedly presenting the CS in the absence of the US
Extinction =
Learning a new relationship, not unlearning.
What is delay conditioning?
The CS continues throughout the trial and only ends once the US has occurred
What is trace conditioning?
The CS is turned off before the US begins
Which kind of conditioning produces the fastest learning?
Delay conditioning
What is backwards conditioning?
The US is presented before the CS, little learning occurs
Latent inhibition
A reduction in learning about a stimulus CS to which there has been prior exposure without any consequence (no US)
Conditioned taste aversion
The taste of a food CS is paired with something unrelated such as bacteria US that makes you sick UR. In the future that taste CS will result in feelings of sickness CR
Stimulus generalization
When similar but untrained stimuli elicit the CR (little Albert)
Associative bias
Where some cues are more likely to be associated with some outcomes (food making you sick)
Two major sensory-input pathways that go to the cerebellum:
The CS input pathway
The US input pathway
There is only one CR output pathway that starts with:
The Purkinje cells and travels down to the interposition nucleus which sends info to the muscles to generate the CR
There is no UR pathway in the cerebellum
True
