its pleasant

Question 3

What does unconditioned response depend on?

Answer 3

type of food
can cause
salivation, approaching, licking - but also avoidance behaviour (for aversive stimuli) can cause avoiding

Question 4

What is extinction?

Answer 4

The removal of the UCS when the CS is presented alone
reduction in behaviour of the conditioned response

(extinction paradigm or procedure)

Question 5

What is Spontaneous Recovery?

Answer 5

When there is a gap in between our UCS presentation and a gap between our extinction when presented with the same CS that has been learnt we see a re-emergence of the conditioned response

Question 6

What is spontaneous recovery?

Answer 6

CR returns after extinction
suggests the learning has not been completely erased
so extinction is new learning rather than unlearning

Question 7

What are the mechanisms behind extinction?

Answer 7

Excitatory association reinforce response

Inhibitory association prevent response

when both are equally strong, cancel each other out
