Punished behavior: Increases in responding after d -amphetamine

Punished behavior: Increases in responding after d -amphetamine 213 41 41 1 1 James W. McKearney James E. Barrett Worcester Foundation for Experimental Biology Shrewsbury Massachusetts Department of Psychology University of Maryland College Park 20742 Maryland USA Abstract Responding maintained in squirrel monkeys under a 10-min fixed-interval schedule of food presentation was suppressed by presenting a shock after every 30 th response (punishment). During alternate 10-min periods of the same experimental session, but in the presence of a different discriminative stimulus, responding either had no effect (extinction) or postponed delivery of an electric shock (avoidance). During sessions when the avoidance schedule was not in effect, d -amphetamine sulfate decreased punished responding. When the avoidance schedule was present during alternate 10-min periods, however, d -amphetamine (0.01–0.56 mg/kg, i.m.) markedly increased responding during punishment components. Increases in responding during avoidance components were also evident. The effects of d -amphetamine on punished responding depend on the context in which that responding occurs. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Psychopharmacology Springer Journals

Abstract

213 41 41 1 1 James W. McKearney James E.

During sessions when the avoidance schedule was not in effect, d -amphetamine sulfate decreased punished responding.
