Abstract
The present data confirm previous reports that freezing in the rat is a useful index of aversive conditioning. Forward conditioning produced reliable CS-evoked freezing in comparison with pseudoconditioning controls. When a white noise was the CS, conditioned freezing increased with shock intensity; when a localized light was the CS, freezing did not vary with shock intensity.
