A. ORTEGA, Leonardo  e  R. PAPINI, Mauricio. The study of incentive contrast: the contribution of Abram Amsel. Rev. Latinoam. Psicol. [online]. 2007, vol.39, n.3, pp. 609-621. ISSN 0120-0534.

This article describes Abram Amsel's [1922-2006] contributions to the study of learning in situations involving surprising reward omissions. Emphasis is placed on recent developments in the study of consummatory successive negative contrast. Amsel's model of psychobiological research involves an integration of behavioral theory with neurobiological and developmental approaches. It is suggested that such a model is often implicit in current research programs that are advancing our understanding of some of the central phenomena in basic psychological theory, including learning, emotion, and conflict.
