Suppose a Person Reinforces a Rat for Responding to an 800-Hz

question 89

Multiple Choice

Suppose a person reinforces a rat for responding to an 800-Hz tone and then observes that its response to a novel 750-Hz tone is about 50 percent 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-percent 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.
