A pigeon responds on a multiple schedule in which a VI 30-second schedule is in effect both when the response key is red and when the response key is green.Next,the schedule associated with the green key is changed to extinction.Which of the following changes in behavior would be an example of positive behavioral contrast-
A)an increase in response rate on the red key
B)a decrease in response rate on the red key
C)an increase in response rate on the green key
D)a decrease in response rate on the green key

Positive behavioral contrast occurs when there is an increase in responding in the presence of a stimulus that remains reinforced while a stimulus associated with extinction experiences a decline in responding. In this scenario, the schedule associated with the green key is changed to extinction, meaning responses on that key will no longer be reinforced. Therefore, the pigeon may show an increase in responding on the red key, which remains on a VI 30-second schedule and is still reinforced. This increase in responding on the red key would be an example of positive behavioral contrast.
