Learned helplessness is the behavior exhibited by a subject after enduring repeated aversive stimuli beyond their control. It was initially thought to be caused by the subject's acceptance of their powerlessness, by way of their discontinuing attempts to escape or avoid the aversive stimulus, even when such alternatives are unambiguously presented.
His theory of learned helplessness is popular among scientific and clinical psychologists. [2] A Review of General Psychology survey, published in 2002, ranked Seligman as the 31st most cited psychologist of the 20th century. [3] Seligman is the Zellerbach Family Professor of Psychology in the University of Pennsylvania's Department of Psychology.
Martin Seligman studies learned helplessness in dogs (1970s) Rosenhan experiment (1972). It involved the use of healthy associates or "pseudopatients", who briefly simulated auditory hallucinations in an attempt to gain admission to 12 different psychiatric hospitals. The hospital staff failed to detect a single pseudopatient.
Seligman confronted dogs with a situation accompanied by a total lack of perceived control, which ultimately lead the dogs to give into the situation. They learned passiveness, helplessness. Seligman transferred his experiments to humans, speculating that perceived control is related to the development of, for instance, depression.
The first two dogs quickly recovered from the experience, but the third dog suffered chronic symptoms of clinical depression as a result of this perceived helplessness. A further series of experiments showed that, similar to humans, under conditions of long-term intense psychological stress, around one third of dogs do not develop learned ...
Overmier has conducted various studies on animal models and physiological impacts in animals. He explored the consequences of exposing dogs to inescapable shocks, observing a reliable disruption of their subsequent escape-avoidance responses in new situations suggesting that these disruptive effects constituted a state of Learned Helplessness.

Stress models including learned helplessness, chronic mild stress, and social defeat stress simulate the impact of stressors on depression. Early life stress models, psychostimulant withdrawal models, olfactory bulbectomy, and genetically engineered mice contribute to a comprehensive understanding of depression's etiology and potential ...
