To study learned helplessness in animals, Seligman, Majer, and Geer (1968) subjected dogs to inescapable electric shock. Four dogs were suspended in a cloth hammock and shocked for 64 trials through electrodes taped to their hind feet. A day later, they were placed in shuttle boxes from which they could escape when shocked, but because they had developed learned helplessness comma the dogs passively accepted the shock rather than escape.
