Cognitive science as an interface between rational and mechanistic explanation

Abstract

Cognitive science views thought as computation; and computation, by its very nature, can be understood in both rational and mechanistic terms. In rational terms, a computation solves some information processing problem (e.g., mapping sensory information into a description of the external world; parsing a sentence; selecting among a set of possible actions). In mechanistic terms, a computation corresponds to causal chain of events in a physical device (in engineering context, a silicon chip; in biological context, the nervous system). The discipline is thus at the interface between two very different styles of explanation-as the papers in the current special issue well illustrate, it explores the interplay of rational and mechanistic forces. © 2014 Cognitive Science Society, Inc.
