AbstractWe propose a novel characterization of the core of cognitive science as the study of how agents perform tasks, where agents and tasks are both broadly construed. We motivate the focus on agents and tasks through a discussion of their prevalence in cognitive science, their utility in identifying topics close to and distant from cognitive science, and their applicability to prominent issues in the field. We argue that our proposal clearly and succinctly highlights the distinctive characteristics of cognitive science and simultaneously motivates its interdisciplinary approach without losing sight of its roots in the study of information processing and cognitive representations.
