| contents | The role of ambiguous expectancy in differential inhibition: a different role for context from direct US association Víctor García Hoz Felisa González Reyes Psicología Ambiguous Expectancy Differential Inhibition Expectancy of Reinforcement Two experiments using the conditioned suppression procedure were carriedout in order to test the role of direct context -US association in differentialinhibition. In Experiment 1, experimental groups differed in inter-trial interval(ITI) and shock density. The results showed that only the short ITI group(higher density shock) passed both retardation and summation tests.Experiment 2 was designed to test whether differences in several kind of ITIsand type of trial presentation could explain differences among groupsundergoing the summation test. Results indicated that ITI is the criticalvariable implicated, but its contribution to inhibitory control of response ismodulated by the type of trial presentation. Only the group with short ITIsand random presentation of trials passed both tests. The critical result wasthat there were no differences in contextual conditioning compared with itsyoked group (trials in alternation). The results are discussed within theframework of the ambiguous expectancy hypothesis for differential inhibitionproposed in this paper. 2000 artículo científico 0211-2159 https://www.redalyc.org/articulo.oa?id=16921201 en http://www.redalyc.org/revista.oa?id=169 Psicológica application/pdf Universitat de València Psicológica (España) Num.2 Vol.21 |
