Lecture 7

Question 1

UCS

Answer 1

Unconditioned stimulus : a stimulus that elicits a reflexive or innate response (the UCR) without prior learning.

Question 2

UCR

Answer 2

Unconditioned Response : a reflexive or innate response that is elicited by a stimulus (the UCS) without prior learning.

Question 3

CS

Answer 3

Conditioned Stimulus : a stimulus that through association with a UCS, comes to elicit a conditioned response similar to the original UCR

Question 4

CR

Answer 4

Conditioned Response : a response (similar to the original UCR) elicited by the CS after learning has occured

Question 5

Behaviour involved in Classical Conditioning and Operant Conditioning

Answer 5

Classical : automatic and reflex-like in response to the UCS

Operant : voluntary and controllable

Question 6

How does learning occur in classical and operant conditioning?

Answer 6

Classical : thru learning trials, UCR becomes associated with the CS (meaning it is now a CR)
Operant : Voluntary responses lead to reinforcers (increase behaviour) or punishers (decrease behaviour)

Question 7

What is the sequence in events for classical and operant conditioning?

Answer 7

Classical : CS > behaviour (CR)

Operant : Behaviour > associated consequences (ie. food comes after button is pressed)
