Abstract
Rats, barpressing for sucrose solution, were divided into three groups, each of which was exposed to a different VI schedule. During each session, four long tone CSs and four short light CSs were followed by a food pellet for half of each group. For the other half, the long CS was a tone and the short CS was light. Response rate increased during long CSs and decreased during short CSs regardless of the type of stimulus. It was concluded that conditioned enhancement and positive conditioned suppression could be brought under stimulus control and that the different phenomena were a function of CS duration.
