MSH: Learned expectation that one's responses are independent of reward and, hence, do not predict or control the occurrence of rewards. Learned helplessness derives from a history, experimentally induced or naturally occurring, of having received punishment/aversive stimulation regardless of responses made. Such circumstances result in an impaired ability to learn. Used for human or animal populations. (APA, Thesaurus of Psychological Index Terms, 1994),CSP: exposure to adverse and uncontrollable events often causes the reaction of helplessness; symptoms include: difficulty in learning behavior patterns in reaction to controllable adversities, reduced motivation in initiating coping responses, and emotional reactions of sadness or depression.
