The similarity of behavior between helpless subjects and depressed individuals provides support for Seligman's model of learned helplessness.

Learned Helplessness

A condition in which an individual learns to feel powerless and stops trying to change their situation, often a result of repeated failures or lack of control.

Seligman's Model

Refers to the learned helplessness theory, proposing that individuals may learn to perceive themselves as powerless in situations of repeated failure or discomfort.

Depressed Individuals

Refers to persons who are experiencing a state of low mood and aversion to activity, significantly affecting their thoughts, behavior, feelings, and sense of well-being.
