A guinea pig can prevent mild footshock by turning a running wheel during a brief tone CS.Early in training,the guinea pig receives several shocks because it fails to spin the wheel in time.However,over several trials the guinea pig successfully learns to prevent the shock.These later successful trials are most correctly referred to as


A) escape trials.
B) avoidance trials.
C) omission trials.
D) acquired drive trials.

One group (Classical Conditioning) of guinea pigs was placed in a running wheel,a tone CS was presented,and 2 seconds later a brief shock was administered.Another group (Avoidance) also was placed in a running wheel,a tone CS was presented,and a brief shock was administered only if the subjects did not move the wheel during the CS presentation.After several trials,what do you suspect was the response to the CS?


A) The classical conditioning group ran more than the avoidance group.
B) The avoidance group ran more than the classical conditioning group.
C) The two groups ran approximately the same amount.
D) Neither group ran much in response to the CS.
