Abstract: Reed studied ecological psychology as an American philosopher of science along the mainline of the biological evolution by investigating the behavioral regulation when animals encounter the environment，based on the Gibson’s thought. First，it extends Gibson’s visual perception theory，including affordance theory，the ecological optics theory as well as ecological information theory. Second，it is combined with the thought of evolutionary psychology，such as ecological dimensions in psychology as well as the evolution of functional systems and neural regulation mechanism. Finally，it develops an ecological view of language，deepening an ecological view of cognition and interpreting the culture and systems theory of representation.This provides an important theoretical basis for evolutionary epistemology and the related fields.
