Two Failures to Prevent Avoidance Decrement
Norman Henry Anderson, Howard A. Rollins · Psychological Reports · 1966
Two experiments were performed in attempts to prevent avoidance decrement (disappearance of an initially learned avoidance response with continued acquisition training). In Exp. 1, widely distributed practice appeared to lower initial performance but did not otherwise prevent the decrement. In Exp. 2, the decrement was found with weak shock, strong shock, and with pulsed strong shock.
