Rethinking people’s conceptions of mental life [Psychological and Cognitive Sciences]

How do people make sense of the emotions, sensations, and cognitive abilities that make up mental life? Pioneering work on the dimensions of mind perception has been interpreted as evidence that people consider mental life to have two core components—experience (e.g., hunger, joy) and agency (e.g., planning, self-control) [Gray HM, et al. (2007) Science 315:619]. We argue that this conclusion is premature: The experience–agency framework may capture people’s understanding of the differences among different beings (e.g., dogs, humans, robots, God) but not how people parse mental life itself. Inspired by Gray et al.’s bottom-up approach, we conducted four large-scale studies designed to assess people’s conceptions of mental life more directly. This led to the discovery of an organization that differs strikingly from the experience–agency framework: Instead of a broad distinction between experience and agency, our studies consistently revealed three fundamental components of mental life—suites of capacities related to the body, the heart, and the mind—with each component encompassing related aspects of both experience and agency. This body–heart–mind framework distinguishes itself from Gray et al.’s experience–agency framework by its clear and importantly different implications for dehumanization, moral reasoning, and other important social phenomena.
