心の理論
Theory of mind is the awareness that people have individual psychological states that differ from one another. Within perspective-taking literature, the term perspective-taking and theory of mind are sometimes used interchangeably and some studies use theory of mind tasks in order to test if someone is engaging in perspective-taking. Some research, however, has highlighted that the two concepts are related but different, with theory of mind being the recognition that another person has different thoughts and feelings and perspective-taking being the ability to take on that other person's point of view.
