A rat is placed in a test arena.When a two-second tone sounds, the rat must push a lever in the arena to prevent a mild footshock from being delivered.If the rat does not push the lever, the shock is delivered periodically until the lever is depressed.On early trials, the rat often fails to push the lever until the shock is delivered.These early trials are referred to as


A) escape trials.
B) punishment trials.
C) avoidance trials.
D) omission trials.

E) None of the above

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.
