Learned helplessness was a theory accidentally propounded by Martin. E.P. Seligman and Steven F. Maier, in the University of Pennsylvania. They were experimenting on dogs using classic conditioning, where if a bell is rung while giving him food, the dog salivates. Later if you just ring the bell, he would still salivate. Professor Seligman later tried experimenting by restraining a dog in a hammock and by giving him harmless shocks.
