We examined the impact of induced goal orientation on individuals' positive‐ and negative‐activating mood when taking part in high‐ or low‐challenging assignments. Results indicated that performing a low‐challenging assignment leads to a higher positive‐activating mood with a performance‐approach orientation than with a mastery approach, or no goal orientation. In contrast, conducting a high‐challenging assignment leads to a higher positive‐activating mood with a mastery approach than with a performance approach, or no goal orientation. These findings suggest that high‐challenging assignments are best instructed with a focus on learning whereas low‐challenging assignments are best instructed with a focus on superior performance.  相似文献

People make systematic errors when matching the location of an unseen index finger with that of a visual target. These errors are consistent over time, but idiosyncratic and surprisingly task-specific. The errors that are made when moving the unseen index finger to a visual target are not consistent with the errors when moving a visual target to the unseen index finger. To test whether such inconsistencies arise because a large part of the matching errors originate during movement execution, we compared errors in moving the unseen finger to a target with biases in deciding which of two visual targets was closer to the index finger before the movement. We found that the judgment as to which is the closest target was consistent with the matching errors. This means that inconsistencies in visuo-proprioceptive matching errors are not caused by systematic errors in movement execution, but are likely to be related to biases in sensory transformations.  相似文献

The authors attempted to identify key contributing factors to school dropout among 3 categories of at‐risk students: those with low grade point averages, those who had been suspended, and those from low socioeconomic backgrounds. Logistic regression analysis of the data, which were derived from the National Longitudinal Survey of Youth‐1997 (U.S. Bureau of Labor Statistics, 2002) indicated that student dropout rates were affected differently by students' membership in the 3 at‐risk categories.  相似文献

The personality traits constraint (CN) and negative emotionality (NE) have been more (CN) or less (NE) consistently associated with alcoholism. The authors examined the association of personality at age 17 with timing of onset and with prospective prediction of nicotine, alcohol, and illicit drug disorders 3 years later in a twin sample (569 females; 432 males). Earlier onset of alcohol and drug disorders (by age 17) was related to significantly lower CN compared with later onsets (by age 20); high NE was related to either onset. NE, as well as CN, uniquely predicted new onsets of all 3 types of substance use disorders by follow-up, with preexisting substance disorders taken into account. Personality traits confer generalized risk for developing any substance disorder, though some traits are more strongly linked with some substance disorders than with others.  相似文献

Eating disorders (EDs) have become one of the biggest mental-health problems in the last decades, especially among youth and women. The present study aims to analyse the suitability of Prochaska and DiClemente’s Transtheoretical Model of Change when applied to the living experiences of people diagnosed with ED and their carers. For this purpose, we applied a narrative biographic approach to the ways in which people face their problems and vital development in the ED domain. Through the narrative analysis of these autobiographies, we aimed to study the patients’ own notions of ‘change’, ‘problem’ and ‘vital trajectory’. We focused on five autobiographic interviews of persons diagnosed as ED (four women and a man). The analysis yields three discourses which organize and give sense to our participants’ vital transitions: a discourse of functional adaptation to events and experiences; one that pays attention to random events and people entering your life; and one that has the personal initiative and agency of an individual agent at its core. It also illuminates particular ways of understanding determination, contemplation and pre-contemplation. These ways of understanding change are shown to extend the possible ways of thinking about people’s lives and ED patients’ perspectives.  相似文献

Abstract

Prolonged Grief Disorder (PGD) is a debilitating syndrome of grief. A recent cognitive behavioral model asserts that three processes are critical to this condition: (1) insufficient integration of the loss with autobiographical knowledge about the self and the lost person; (2) negative cognitions; and (3) anxious and depressive avoidance behaviors. These processes are assumed to contribute to PGD symptoms and to mediate the influence of personality-related vulnerabilities on the development and maintenance of these symptoms. The present study examined the mediational role of these three processes in the linkage between neuroticism, attachment anxiety, and attachment avoidance on the one hand and PGD symptom severity on the other hand. Self-reported data from 348 bereaved people were used. The results showed that the three personality variables were significantly associated with PGD symptom severity. Moreover, the results provided support for the mediating effects of indices of insufficient integration, negative cognitions, as well as avoidance behaviors – even after controlling for the shared variance between mediators. Theoretical and clinical implications are discussed.  相似文献

Three experiments investigated the effectiveness of presenting procedural information through different media and their combinations. Experiment 1 examined the effectiveness of text, line drawings, text and line drawings, video. and video stills for learning a first aid task. The results showed an advantage of text and line drawings and of the video presentation over the other three conditions for both bandaging performance and answering questions about the task. Experiment 2 showed that the beneficial effect of the combination of text and pictures could not be accounted for simply in terms of a dual coding explanation. Rather, the effectiveness of the media and their combinations was influenced by the extent to which they conveyed action information. Finally, Experiment 3 showed no evidence of a contiguity effect: text and pictures were as effective when presented together on the same screen as when they were presented separately.

This study examined the correlates of within-job title variance in job-analytic ratings. Q-factor analyses of SMEs' ratings for two jobs (i.e., Sales Representative [n = 26] and Felony Assistant Public Defender [n = 141]) yielded two and four factors, respectively. These factors represented shared views of the importance of the job tasks. Factor membership was related to sales performance for sales representatives. Previous professional experience and district of employment were related to factor membership for Felony Assistant Public Defenders. The implications of these studies of within-title variance in job-analytic ratings for human resource programs are discussed.  相似文献
