Guinea pigs trained to turn head L or R to buzzer
Could reverse contingency
Behaviour change due to operant (as reward)

Answer 3

lever up or down
Punished for one response

Answer 5

supports cognitive theory as pair injection makes sick which reduces responding
Decreases desire for reinforcer so decrease in instrumental response

Question 6

Wantanabe (1996)

Answer 6

Rowe (2000)

Answer 7
