Depressed and nondepressed college students received experience with solvable, unsolvable, or no discrimination problems. When later tested on a series of patterned anagrams, depressed groups performed worse than nondepressed groups, and unsolvable groups performed worse than solvable and control groups. As predicted by the learned helplessness model of depression, nondepressed subjects given unsolvable problems showed anagram deficits parallel to those found in naturally occurring depression. When depressed subjects attributed their failure to the difficulty of the problems rather than to their own incompetence, performance improved strikingly. So, failure in itself is apparently not sufficient to produce helplessness deficits in man, but failure that leads to a decreased belief in personal competence is sufficient. 相似文献

Learned helplessness in children: a longitudinal study of depression, achievement, and explanatory style 总被引:12,自引:0,他引:12

In this longitudinal study, the depressive symptoms, life events, and explanatory styles of 168 school children were measured five times during the course of 1 year. Measures of school achievement were obtained once during the year. Depressive symptoms and explanatory styles were found to be quite stable over the year. As predicted by the reformulated learned helplessness theory, explanatory style both correlated with concurrent levels of depression and school achievement and predicted later changes in depression during the year. Depression also predicted later explanatory styles. The implications of these results for intervention with children with depressive symptoms or school achievement problems are discussed. 相似文献

Correlated pessimistic explanatory style--the belief that negative events are caused by internal, stable, and global factors--with lowered immunocompetence in a sample of 26 older adults. Two measures of cell-mediated immunity--T-helper cell/T-suppressor cell ratio and T-lymphocyte response to mitogen challenge--were lower in individuals with a pessimistic style, controlling for the influence of current health, depression, medication, recent weight change, sleep, and alcohol use. A relative increase in the percentage of T-suppressor cells seemed to underlie this immunosuppression. Although the mechanism by which explanatory style might influence immune function remains unknown, we speculate that a pessimistic style might be an important psychological risk factor--at least among older people--in the early course of certain immune-mediated diseases. 相似文献
