Lecture 5 - Problems with S-R Theory: Skinner, then Associative Learning

Question 1

Three Problems for Hull-Spence S-R Theory

Answer 1

1. Learning without reinforcement - you have no motivation.
2. Reinforcement without drive reduction
3. Extinction, punishment and avoidance learning

Question 2

Kamin’s Blocking Effect

Answer 2

Variable interval schedule generates a very steady baseline response. You introduce a Pavlovian contingency (noise than shock). The noise as a predictor of shock has suppressed the conditioned response.

1. Noise -> shock
2. Light + noise -> shock
3. Test light alone
   Result: no fear of light; only noise; learning occurs only when something unexpected happens - role of surprise
