On a multiple FI 20-sec VI 60-sec schedule of reinforcement, the first component is changed to an FI 200-sec schedule. As a result, the rate of response on the VI 60-sec schedule will most likely:
A) remain the same.
B) decrease.
C) increase.
D) become unpredictable.

Question

Quizplus · Accepted Answer

When the first component is changed to a longer interval (FI 200-sec), the rate of reinforcement decreases, which can lead to an increase in responding in the second component (VI 60-sec) due to the contrast effect, where the organism responds more in the unchanged component when the other component becomes less reinforcing.
