Abstract

The target article provides a useful investigative model for studying social behaviors, but it falls short of establishing a more comprehensive conceptual framework for understanding complex social inter- actions. Social behaviors such as play involve a dynamic and complex interplay between two or more organisms. Even when feed-forward mechanisms are taken into account and the model is anchored to evolutionary theory, the utility of this model is still limited by the conspicuous absence of neurobiological theory and data.
