Beyond the Reaction Range Concept: A Developmental, Contextual, and Situational Model of the Heredity-Environment Interplay

Abstract

Despite its popularity, the reaction range concept has several limitations that obscure the complexity of the heredity and environment interplay. This article presents a model that broadens the inherent limitations of the reaction range concept by including (a) multiple sources of variation, (b) changing contributions across development, and (c) dynamic influences of context and situation. The model is intended to expand the focus on sources of variation and to offer heuristic tools for hypothesis generation.
