The study by Seligman and Maier (1967) investigates the effects of inescapable shock on subsequent escape/avoidance behavior in dogs. The researchers found that dogs who initially learned to escape shock by pressing panels in a harness subsequently showed normal acquisition of escape/avoidance behavior in a shuttle box. However, dogs that experienced inescapable shock in the harness exhibited interference with their ability to escape in the shuttle box. This interference was mitigated if the dogs had prior experience with escapable shock in the shuttle box. The results suggest that dogs learned that shock termination was independent of their responses, leading to a "learned helplessness" phenomenon where they failed to escape shock in the shuttle box. The study also explored the role of learned helplessness in appetitive situations and its potential transfer between aversive and appetitive contexts.The study by Seligman and Maier (1967) investigates the effects of inescapable shock on subsequent escape/avoidance behavior in dogs.
