ABSTRACT. Cybernetic theories of self-regulation contend that an individual's goal system may work best to the extent it is differentiated. The present investigation pioneered an assessment of goal differentiation in relation to an important feature of goals—intrinsic motivation—and quantified the extent to which intrinsic motivation systematically increased from low- to mid- to high-level goals, the resulting individual difference termed cybernetic self-determination. In Study 1 (n = 106), it was found that frustrating daily events precipitated motivations to quit at low, but not high, levels of cybernetic self-determination. In Study 2 (n = 111), it was found that negative feedback was associated with reduced goal persistence at low, but not high, levels of cybernetic self-determination. The findings therefore converge on the idea that individual differences in cybernetic self-determination are consequential in buffering reactions to obstacles in daily life. Implications for personality, motivation, and self-regulation literatures are discussed.  相似文献

Little is known about how family functioning relates to psychosocial functioning of youth with inflammatory bowel disease (IBD). The study aim was to examine family problem solving and affective involvement as moderators between adolescent disease severity and depressive symptoms. Participants were 122 adolescents with IBD and their parents. Measures included self-reported and parent-reported adolescent depressive symptoms, parent-reported family functioning, and physician-completed measures of disease severity. Disease severity was a significant predictor of adolescent-reported depressive symptoms, but not parent-reported adolescent depressive symptoms. Family affective involvement significantly predicted parent-reported adolescent depressive symptoms, while family problem-solving significantly predicted adolescent self-report of depressive symptoms. Neither affective involvement nor problem-solving served as moderators. Family affective involvement may play an important role in adolescent emotional functioning but may not moderate the effect of disease severity on depressive symptoms. Research should continue to examine effects of family functioning on youth emotional functioning and include a sample with a wider range of disease severity to determine if interventions aimed to enhance family functioning are warranted.  相似文献

Although lexical semantic deficits are postulated to play a prominent role in the anomia of Alzheimer's disease, it is unclear whether the primary disturbance is one of lexical access or one of lexical semantic loss. Response consistency on a naming task is one means of evaluating the underlying source of naming impairment. Access dysfunction usually implies variable word-finding difficulty, while a theory of lexical loss predicts that many word names would be consistently unavailable. Nineteen Alzheimer's disease patients were administered a visual confrontation naming task (the Boston Naming Test) on two occasions 6 months apart. Eighty percent of errors occurred consistently at both times; only 20% of errors occurred on only one occasion. Response consistency occurred significantly more often than expected under the assumption of no response consistency. Findings support the hypothesis that anomia in Alzheimer's disease is in part due to a loss of lexical semantic information.  相似文献
