Theory of mind (often abbreviated ToM) is the ability to attribute mental states— beliefs, intents, desires, pretending, knowledge, etc.—to oneself and others and to understand that others have beliefs, desires, intentions, and perspectives that are different from one's own. Deficits can occur in people with autism spectrum disorders, schizophrenia, attention deficit hyperactivity disorder, as well as alcoholics who have suffered brain damage due to alcohol's neurotoxicity. Although philosophical approaches to this exist, the theory of mind as such is distinct from the philosophy of mind.
