Abstract
Rats were shocked, continuously or intermittently, by an electrical stimulus whose intensity increased by one step every 20 seconds. Each time the rat depressed a lever in the experimental chamber, shock intensity was decreased by one step. Lever-pressing was maintained on such a program, with both continuous and intermittent delivery of shock.Entities:
