Abstract
After 7 days’ VI training for water reinforcement, 14 rats were given six (three per day) noise-shock pairings with lever retracted. Following a recovery day, Ss received two daily noise/no-shock presentations for 6 days with lever initially present only for control Ss. After 3 days, lever was returned for experimental Ss who displayed reliably more suppression on Extinction Days 4–6.
