Theory of mind
Individuals in a current major depressive episode, a disorder characterized by social impairment, show deficits in theory of mind decoding. Theory of mind decoding is the ability to use information available in the immediate environment (e.g., facial expression, tone of voice, body posture) to accurately label the mental states of others. The opposite pattern, enhanced theory of mind, is observed in individuals vulnerable to depression, including those individuals with past major depressive disorder (MDD), dysphoric individuals, and individuals with a maternal history of MDD.
