Abstract

This article suggests that, in prehistoric man, the results of competition magnified the effect of small genetic differences between competing individuals, thereby increasing the differential in their relative reproductive success (difference amplification). This had the effect of accelerating the evolution of early man. The differential effect of success and failure on competing individuals led to "difference amplification". These mechanisms can still be observed today. This model is relevant to psychotherapy with depressed clients. (PsycINFO Database Record (c) 2010 APA, all rights reserved) (journal abstract)
