An experimental study on spontaneous recovery of conditioned reward expectancies and instrumental responding in humans.

摘要: The aim of the present study was to investigate spontaneous recovery reward-expectancies and a reward-associated response in humans assess individual factors affecting recovery. We therefore implemented an experimental procedure comprising three separate test-sessions. In first test-session, participants underwent instrumental discrimination training acquire conditioned response, second memory this tested followed by extinction training. third assessed. Our results demonstrate extinguished expectancies indicate that differential after impulsivity significantly predicted magnitude contrast, limited evidence for responding found. Given might trigger these findings underline importance developing procedures lead more complete less fragile long-term responses.
