Theory Of Mind (ToM)
Theory of the Mind (ToM) refers to the ability humans have to recognize and attribute mental states not only in themselves but in other people, and to understand that feelings and beliefs we have may be different than others.
For example, you may view yourself as a happy, good natured person, but recognize that others may not always be exactly like you - others may be angry, hurtful, etc.
The theory also states that there are mental conditions that prevent some people from being able to recognize mental states in others. Some conditions that interfere with this include autism spectrum disorders, schizophrenia, ADHD, etc.
