Dans cette expérience de terrain, on applique la théorie de la fixation des objectifs au sentiment d’efficacité personnelle d’étudiants, à leur satisfaction envers le programme du MBA aussi bien qu’à leur performance (GPA). Immédiatement après leur avoir fixé des objectifs spécifiques élevés, nous avons mesuré le sentiment d’efficacité personnelle des étudiants en MBA. Celui des étudiants de la condition “objectifs de résultats pour la fin de l’année” (long terme) était inférieur à celui de sujets qui étaient dans la condition “faites de votre mieux” ou dans celle “but d’apprentissage”. Les sujets présentant des difficultés spécifiques en ce qui concerne les buts d’apprentissage sont plus satisfaits du programme MBA que ceux des autres conditions expérimentales. Le GPA était significativement plus élevé dans la condition “but d’apprentissage” que dans celle “but de performance”à long terme. Les sujets qui ont des objectifs à court terme et un objectif de résultat à long terme ont un GPA plus élevé que ceux qui ont seulement un objectif à long terme ou que ceux qui sont dans l’urgence de faire de leur mieux. Les implications de ces résultats pour la théorie et la pratique sont discutées. The present field experiment examined the application of goal setting theory on student self‐efficacy, satisfaction with the MBA program, as well as performance (i.e. GPA). Immediately after setting specific high goals, the self‐efficacy of MBA students who set year end (distal) outcome goals was lower than participants in either the “do your best” or the learning goal conditions. Participants who set specific difficult learning goals had higher satisfaction with the MBA program than those in other experimental conditions. GPA was significantly higher in the learning goal condition relative to the distal performance goal condition. Participants who set proximal goals, in addition to a distal outcome goal, had a higher GPA than those who only set a distal goal or those who were urged to do their best. Implications of these findings for theory and practice are discussed.  相似文献

We examined the factor structure of the Children's Depression Inventory (CDI) among a sample of 523 African American children (m age = 12.76) and a sample of 564 European American youth (m age = 12.43). Previous investigations have produced discrepant factor structures among samples of predominantly majority-culture children, but fewer investigations of the factor structure of the CDI have been conducted among non-European American samples. Confirmatory factor analyses of the original 5 factors identified by Kovacs (1983, 1991) revealed that the items had invariant measurement properties across the samples. The latent factor structure, however, revealed telling differences between the two samples. For European American youth, only one of the original five factors was meaningfully differentiated from the others, whereas for the African American youth, two of the factors clearly emerged as unique facets of depression. Consistent with other reports, between-group mean differences on the CDI and its factors were noted. We argue that further validation of the CDI among traditionally underserved populations is warranted. Predictive validation investigations, in particular, are needed to examine the relationship between CDI factor scores and clinical outcomes.  相似文献

  The clinical and psychosocial characteristics of 239 dieting and nondieting adolescents (61% female; mean age=15.3) recruited from an inpatient psychiatric setting were examined. Dieting adolescents were compared to nondieting adolescents on exercise frequency, weight control behaviors, risky behaviors, psychiatric comorbidity and distress, eating disorder symptomatology, smoking, coping, and family factors. While dieters did not statistically differ from nondieters on scores of body mass index, dieting youth reported greater levels of self-reported distress, poorer coping, greater eating disorder symptomatology, and were more likely to engage in extreme weight control behaviors. In addition, dieting was associated with higher rates of major depression (58% vs 34%) and eating disorders (14% vs 1%). Among adolescent smokers, dieters endorsed smoking as a weight control behavior. Engaging in risky behaviors or familial factors did not differentiate dieters from nondieters. Given the number of negative correlates associated with dieting in adolescents, identifying dieting and weight control behaviors in clinical settings may prove to be an effective strategy in the development of prevention and intervention efforts for youth.  相似文献

In the current paper we investigate whether gender affects the encoding of leadership behavior. In three studies we found evidence that perceivers had difficulty encoding leadership behaviors into their underlying prototypical leadership traits when the behavior implied an agentic trait and the behavior was enacted by a female. Using a lexical decision making task, in Study 1 we demonstrated that agentic leadership traits were less accessible than communal leadership traits when the leader was female. Additionally, Study 1 also demonstrated that agentic traits were less accessible when the leader was female versus male. In Studies 2a and 2b, we replicated the differences we found for agentic leadership behaviors using perceiver’s self-ratings as the dependent variable. Results are discussed both in terms of their implications for future research on gender bias in leadership and their practical implications for eliminating gender bias against females who aspire to leadership positions.  相似文献

The current study set out to examine how the presence or absence of depicted characters in visual narratives influences the degree of character-related content in improvised stories. The experiment consisted of trials of oral storytelling that were prompted by wordless comics. The degree of character content in the storylines was varied from being character-based—showing people engaging in social interactions—to being characterless, for example scenes depicting natural phenomena. An intermediate “character-implied” condition was also investigated, exemplified by the scene of a tornado passing through a town, where no people were depicted but in which their presence was strongly suggested. Linguistic content analysis of 472 stories demonstrated indistinguishable use of third-person pronouns (she/he) between character-implied and character-containing scenarios. An analysis of character presence demonstrated that storytellers inserted protagonists into the character-implied stories as vehicles for the actions taking place. This phenomenon reveals the character-driven nature of story creation.  相似文献

In Bayesian belief revision a Bayesian agent revises his prior belief by conditionalizing the prior on some evidence using Bayes’ rule. We define a hierarchy of modal logics that capture the logical features of Bayesian belief revision. Elements in the hierarchy are distinguished by the cardinality of the set of elementary propositions on which the agent’s prior is defined. Inclusions among the modal logics in the hierarchy are determined. By linking the modal logics in the hierarchy to the strongest modal companion of Medvedev’s logic of finite problems it is shown that the modal logic of belief revision determined by probabilities on a finite set of elementary propositions is not finitely axiomatizable.

Life balance is indicative of creating and sustaining a meaningful and satisfying quality of living. Contrarily, work addiction is overinvesting in work‐related behaviors, thereby truncating important life‐balance domains. Given a growing body of literature specific to life balance and the increasing incidence of work addiction and burnout among professionals, the authors evaluated life balance and work addiction among 409 professionals in high‐pressure, high‐demand careers. A strong relationship between life‐balance domains and the propensity toward work addiction was noted. Specifically, stress/anxiety and sleep disturbances were identified as work addiction indicators reducing perceptions of life balance. Counselors should assess these critical domains with clients working in high‐pressure, high‐demand careers and be prepared to support these professionals as they restructure their lives to improve life‐balance domains.  相似文献
