Descripción:

Seligman is a strong promoter within the scientific community of his theories of positive psychology and of well-being. His theory of learned helplessness is popular among scientific and clinical psychologists. Seligman developed the theory further, finding learned helplessness to be a psychological condition in which a human being or an animal has learned to act or behave helplessly in a particular situation. Usually after experiencing some inability to avoid an adverse situation. Even when it actually has the power to change its unpleasant or even harmful circumstance.
