Through the use of longitudinal survey data the change of achievement goal orientations was tested in a sample of middle school students in mathematics as they moved from sixth to seventh grade. Achievement goals include task goals and performance goals, with the partitioning of performance goals into approach and avoidance components. Results indicate that all goal orientations were moderately stable over time. Task goals in sixth grade positively predicted academic efficacy in seventh grade. Performance-approach goals in sixth grade positively predicted performance-avoid goals in seventh grade. Multiple regression and multi-sample analyses revealed that the path from performance-approach goals to performance-avoid goals was significant only among students reporting high academic efficacy before the transition. The results suggest that individuals who feel efficacious in math while endorsing a performance-approach goal orientation may be particularly vulnerable to adopting maladaptive performance-avoid goals over time and with change in circumstances. 相似文献

ABSTRACT Prospective memory involves remembering to perform intended actions in the future. Previous work with the multinomial model of event-based prospective memory indicated that adult age-related differences in prospective-memory performance were due to the prospective (not the retrospective) component of the task (Smith & Bayen, 2006, Journal of Experimental Psychology: Learning, Memory, and Cognition, 32, 623). However, ongoing-task performance was also lower in older adults in that study. In the current study with young and older adults, the difficulty of the ongoing task was manipulated by varying the number of colors per trial to create easier and harder versions of the ongoing task for each age group. The easier version included 2 colors per trial for older adults and 4 colors for young adults. The harder version included 4 colors for older adults and 6 colors for young adults. By adjusting the ongoing-task difficulty, older adults were able to perform the ongoing task as well or better than the young adults. Analyses with the multinomial model revealed that making the ongoing task easier for older adults (or more difficult for young adults) did not eliminate age-related differences in prospective-memory performance and the underlying prospective component. 相似文献

The mechanisms of naltrexone's effects on urges to drink during abstinence are unclear. Naltrexone may suppress either urges to drink specifically or appetitive responses in general. The effects of naltrexone on cue reactivity to alcoholic and sweet nonalcoholic beverages were investigated. Alcohol-dependent men (N = 53) in treatment received naltrexone (50 mg) or placebo. Four hours later, they received baseline assessment, exposure to fruit juice, and exposure to their usual alcoholic beverage in 3-min trials. Naltrexone reduced urge to drink and self-reported attention to the alcohol cues, not at the initial exposure but after repeated exposures to alcohol cues. Naltrexone reduced negative affect across baseline and alcohol trials. No effects of naltrexone on responses to the nonalcoholic appetitive beverage cues were found, suggesting that general appetite suppression does not mediate the effects of naltrexone on urges. 相似文献

Category learning with minimal prior knowledge 总被引:3,自引:0,他引:3

In 6 experiments, the authors examined the use of prior knowledge in category learning. Previous studies of the effects of knowledge on category learning have used categories in which knowledge was related to all of the category's features. However, people's knowledge of real-world categories often consists of many "rote" features that are not related to their prior knowledge. Five experiments found that even minimal prior knowledge (1 knowledge-relevant feature and 5 rote features per exemplar) can facilitate category learning. Posttests revealed that although the knowledge aided learning, subjects also acquired the rote features that were not related to knowledge, contradicting predictions of an attentional explanation of the knowledge effect. The results of Experiment 6 suggested that subjects attempt to link even rote features to their knowledge. 相似文献

Dispositional traits and life narratives represent two different levels of personality that have not previously been empirically linked. The current study tested five hypotheses connecting Big-Five traits to life-narrative indices of emotional tone, theme, and structure. Students (Study 1) and adults (Study 2) completed a self-report measure of the Big-Five traits and provided extended written accounts of either ten (students) or eight (adults) key life-narrative scenes, including life high points, low points, and turning points. Content analysis of the narrative data revealed that for both samples Neuroticism was positively associated with an emotionally negative life-narrative tone, Agreeableness was correlated with narrative themes of communion (e.g., friendship, caring for others), and Openness was strongly associated with the structural complexity of life narrative accounts. Contrary to prediction, however, Conscientiousness was not consistently associated with themes of agency (e.g., achievement, self-mastery) and Extraversion was unrelated to positive narrative tone. The results are discussed in the context of contemporary research and theorizing on the narrative study of lives and the relation of narrative research in personality to more conventional, trait-based approaches. 相似文献

This study is based on interviews with four focus groups consisting of fourteen white, Latina, and black girls, ages 13 to 16 years, from diverse backgrounds. The objectives of the study are to gain insight into what forum girls use to learn about the adolescent experience and to examine teenage girls' views of their sexuality and femininity. The girls' discussion of their lives and perceptions of the teen magazine Seventeen reveal a displacement of female sexuality. The magazine's message to teenage girls of gaining self-worth through emphasized femininity seems to resonate with these girls regardless of class and race. We conclude that responsible adults need to challenge the distorted media images of adolescent development and teenage girls' sexuality. 相似文献
