Abstract
Conditioned suppression is often regarded as an ideal procedure for studying the interaction between operant and Pavlovian conditioning. The present paper surveys the results of 103 conditioned suppression experiments with regard to differences in a number of key procedural and parametric variables (e.g., on- vs. off-baseline training, number of sessions, CS duration, US duration, and intensity). It was concluded that, despite extensive differences in the stimulus arrangements that are in use, the results of the conditioned suppression procedure are remarkably stable: A positively reinforced operant baseline is suppressed during exposure to a signal which precedes an unavoidable aversive event.
