- Differences in Extinction of an Appetitive Instrumental Response in Female Inbred Roman High- (RHA-I) and Low- (RLA-I) Avoidance Rats María J. Gómez Lourdes de la Torre José E. Callejas-Aguilera Juan M. Rosas María D. Escarabajal Ángeles Agüero Adolf Tobeña Albert Fernández-Teruel Carmen Torres Psicología An experiment was conducted with the goal of exploring strain differences between female inbred Roman High and Low Avoidance rats (RHA-I, and RLA-I, respectively) on acquisition and extinction of a food-rewarded running response in a straight alley. Acquisition proceeded faster in the less emotional RHA-I and Wistar rats (used as controls) than in the more emotional RLA-I rats. However, extinction proceeded slower in RHA-I rats than in RLA-I and Wistar rats. This strain-based asymmetry on instrumental performance between acquisition and extinction is discussed in terms of strain differences in locomotor activity, associative flexibility and emotional reactivity. 2009 artículo científico 0211-2159 https://www.redalyc.org/articulo.oa?id=16911991002 en http://www.redalyc.org/revista.oa?id=169 Psicológica application/pdf Universitat de València Psicológica (España) Num.2 Vol.30
