Suppose We Reinforce a Rat for Responding to an 800-Hz

question 82

Multiple Choice

Suppose we reinforce a rat for responding to an 800-Hz tone,and we then observe that its response to a novel 750-Hz tone is about 50% of its response to the 800-Hz tone.The lower response to the 750-Hz tone occurs because the rat:

• A)cannot tell the difference between the two tones,so it responds by guessing.
• B)expects a 50% probability that its response will lead to a reward.
• C)can hear the 750-Hz tone about half as well as the 800-Hz tone.
• D)has learned to discriminate between the tones;therefore,it makes different responses to them.
