Abstract
Three groups of rats received electroconvulsive shock (ECS) 10 sec., 2 min., or 5 hr. after one-trial avoidance training. These Ss as well as additional no-ECS control Ss were tested for retention 25 hr. afterward. Three more groups received one-trial avoidance training followed by a test of retention 10 sec., 2 min., or 5 hr. later. Both the ECS gradient effect and the incubation effect were demonstrated. The close relationship between the two functions suggested a new interpretation of the ECS gradient effect.
