What is Theory of Mind?

Theory of mind is the ability to attribute mental states — beliefs, intents, desires, emotions, and knowledge — to ourselves and others. “As humans we assume that others want, think, believe and the like, and thereby infer states that are not directly observable, using these states anticipatorily, to predict the behavior of others as well as our own. These inferences, which amount to a theory of mind, are to our knowledge, universal in human adults” (Premack & Woodruff, 1978). Having a theory of mind allows us to understand that others have unique beliefs and desires that are different from our own, enabling us to engage in daily social interaction as we interpret the mental states and infer the behaviors of those around us (Premack & Woodruff, 1978).
