其他摘要：The possibility of modifying the electrodennal activity using pu· nishment procedures was experimentally investigated. Subjects were given aversíve stímulation, contingent or non-contingento to the eIDlission of electrodermal activity. The influence of awareness and punishment expectancy was experímentally controlled. Results indicate a diminishing of response frequency in all the experimental condítíons, Probably results are due to habituation and not to conditioning. Contingeney and punishment awareness are considered irrevelant. On the other hand, expectation is considered an important variable very relevant to the rate of emission of an electrodermal response previously punished
