LONG ANSWER 6

Was Pavlov an S-S or S-R theorist ?

Pavlov was an S-S theorist. He focused on the association of one stimulus to another. CS predicts US

What are the 3 stages of a US devaluation experiment including the test stage?

1. CS-US PAIRINGS: CS is paired with US to evoke CR.

2. US DEVALUATION: value of the US is reduced, leading to phase 3

3. CS ALONE- where CS paired with a new stimulus will evoke a new CR.

EXAMPLE: 1. Ringing of bell paired with food= dog will salivate. 2. If food is poisoned= an aversive reaction occurs. 3. Next time the bell is rung the dog will salivate less, because it is responding to the devalued US.

What does the US devaluation effect tell us about whether learning is S-S or S-R?

US devaluation will tell us that the learning is S-S if the evoked response reflects the devalued US, whereas if the evoked response reflects the original US, the learning is S-R.

In S-R learning the US does not affect the CR.

Which of these theories, S-S, or S-R, is confirmed?

S-S theory is confirmed.
