We used meta-analysis to obtain a comprehensive perspective on the construct validity of achievement goals, focusing on the most recent addition to the achievement goal framework, mastery-avoidance (Elliot & McGregor, 2001). Mastery-avoidance achievement goals positively correlated with need for achievement, perceived competence, competitiveness, interest, negative affect, and other achievement goals (mastery-approach, performance-approach, performance-avoidance) and negatively correlated with cognitive ability, help seeking, and performance. The correlations between mastery-avoidance and the other achievement goals were moderate. Thus, we conclude that mastery-avoidance is a conceptually and empirically distinct construct with unique antecedents and consequences and should be included in future studies on achievement goals. 相似文献

The purpose of this study was to evaluate whether the training and experience of assessors to record behaviors as part of an actual organizational assessment center (AC) would transfer to another context: performance appraisals. Specifically, we examined the effects of transfer of training on managers' behavioral specificity in comments on performance evaluations. Performance appraisal comments from managers who had received training and participated as an assessor and from managers who had not were compared. Analyses revealed significant differences between managers who were trained as assessors compared with managers who were not, suggesting transfer of training effects. Results provide the first empirical evidence for an added benefit of AC assessor participation and training. 相似文献

Online social networking is vastly popular and permits its members to post their thoughts as microblogs, an opportunity that people exploit, on Facebook alone, over 30 million times an hour. Such trivial ephemera, one might think, should vanish quickly from memory; conversely, they may comprise the sort of information that our memories are tuned to recognize, if that which we readily generate, we also readily store. In the first two experiments, participants’ memory for Facebook posts was found to be strikingly stronger than their memory for human faces or sentences from books—a magnitude comparable to the difference in memory strength between amnesics and healthy controls. The second experiment suggested that this difference is not due to Facebook posts spontaneously generating social elaboration, because memory for posts is enhanced as much by adding social elaboration as is memory for book sentences. Our final experiment, using headlines, sentences, and reader comments from articles, suggested that the remarkable memory for microblogs is also not due to their completeness or simply their topic, but may be a more general phenomenon of their being the largely spontaneous and natural emanations of the human mind. 相似文献

In this study, we investigated the interaction between givenness and complexity on the choice of syntactic structure, via two experiments using speeded acceptability judgments. Experiment 1 showed that for the Danish dative alternation, given–new orders are only easier to process for double-object or NP constructions, whereas PP constructions are unaffected. This replicates previous findings for the English dative alternation. Experiment 2 revealed that when a long NP precedes a short NP—a suboptimal complexity relation—the effect of givenness is neutralized, whereas givenness remains influential when the complexity relation between the NPs in the sentence is optimal. This is consistent with the view that in online parsing, the actual syntactic structure-building process is primary, whereas any higher-order computations such as discourse linking are secondary. The relative complexity of the NPs in the double-object construction directly affects the structure-building process, whereas the decoding of the discourse structure is a later and less crucial phenomenon, resulting in neutralization of the givenness effect in cases in which the complexity relation is suboptimal. 相似文献

This multi-method study examines tensions in the practice of youth-led participatory research (YPAR) in urban high schools among 15 semester-cohorts. Student participants in the present study were 77 ethnically diverse youth from four high schools in a major metropolitan school district. Data were gathered using systematic classroom observations, interviews with teachers and students involved in the projects, and participant observation. The two most commonly-constrained phases of the YPAR project were issue selection and action steps. A central tension in the issue selection phase for projects enacted across multiple semester cohorts was the tension between original inquiry and “traction:” Sticking with the same topic enabled sustained building of strategic alliances and expertise for making change, but limited the incoming cohort’s power to define the problem to be addressed. In further analyses, we identified processes that promoted student power despite continuity-related constraints—teachers’ framing and buy-in strategies, “micro-power” compensation, and alignment of students’ interests with the prior cohort—as well as constraints in other phases of the projects. This study’s findings regarding the promotion of youth power in the face of constraints advance the integration of theory and practice in youth-led research and have implications for participatory research more broadly. 相似文献

This study examines the impact of changes in the influence of several individual-level constructs (e.g., risk-seeking, family, peers, attitudes) on involvement in substance use and delinquent behavior during mid to late adolescence. Data were drawn from the longitudinal evaluation of the Gang Resistance, Education, and Training (G.R.E.A.T.) program. The final pooled time series samples used in the analyses were n = 2,515 in the delinquency model (original sample: n = 847) and n = 2,250 in the substance use model (original sample: n = 849). Fixed effects negative binomial modeling indicated that: (1) changes in risk-seeking, parental and peer influences, and attitudes are significantly related to the frequency of self-reported delinquency and substance use and (2) similar risk factors, drawn from multiple domains, influence the likelihood of greater involvement in both delinquency and substance use during mid to late adolescence. Findings highlight the importance of considering a variety of dynamic processes during adolescence and their potential changing influence on deviant behaviors. 相似文献

Smoking in many Western societies has become a both moral aand health issue in recent years, but little is known about how smokers position themselves and regulate their behaviour in this context. In this article, we report the findings from a study investigating how smokers from an economically disadvantaged community in the East Midlands (UK) respond to concerns about the health impact of smoking on others. We conducted ten focus group (FG) discussions with mixed groups (by smoking status and gender; N?=?58 participants) covering a range of topics, including smoking norms, self-regulation, and smoking in diverse contexts. We transcribed all FG discussions before analysing the data using techniques from discourse anlysis. Smokers in general positioned themselves as socially responsible smokers and morally upstanding citizens. This position was bolstered in two main ways: ‘everyday accommodation’, whereby everyday efforts to accommodate the needs of non-smokers were referenced, and ‘taking a stand’, whereby proactive interventions to prevent smoking in (young) others were cited. We suggest that smoking cessation campaigns could usefully be informed by this ethic of care for others. 相似文献

Past measurement of vitality has included both emotional and physical components. Since aspects of physical vitality such as fatigue can be indicative of physical illness, the usefulness of existing measures of vitality to predict health is limited. This research was designed to examine the psychometric properties of a new Mental Vitality Scale and to test its associations with measures of cardiovascular health over the course of 2 years. The measure of mental vitality was administered in a two-part study using three different samples. In part 1, the reliability and validity of the scale was assessed with a student and a clinic sample. In part 2, medical data on mental and physical health were abstracted over a two-year period from 1041 patient records from a multi-specialty medical practice, and mental vitality assessed through a mailed questionnaire. The findings indicate that the Mental Vitality Scale is a valid and reliable questionnaire for measuring this construct. Mental vitality was also associated with reduced odds of several cardiovascular outcomes and prospective analyses suggest that mental vitality may serve a protective function in the development of cardiovascular disease. The results lend support for the importance of mental vitality as a construct that may be relevant for considering resilience in relation to cardiovascular disease. 相似文献

This study tested the potential to elicit a broadened attentional focus through writing about a positive life experience and to derive health benefits from such writing. Participants (n = 38) wrote for 20 min each day for 3 consecutive days about either a positive life experience or a control topic. Writing about positive experiences led to improved physical health (measured 4–6 weeks after writing) compared to control and higher levels of global cognitive focus after writing mediated this effect. Notably, while the positive writing condition was more broadened than control, positive affect was not responsible for this difference. Implications for disclosive writing and the broaden and build model are discussed. 相似文献

Abstract Two studies examined the association of gender and occupational group (nursing versus non-nursing) with perceived risk of abuse (sexual harassment and verbal and physical abuse) as well as the relationship of perceived abuse risk with burnout and sense of community. Study 1, comprising of two settings (tertiary care hospital, N = 3,062; psychiatric hospital, N = 383), found gender and occupational group associated with perceived risk of abuse (women felt greater risk than men; nurses felt greater risk than non-nurses). It also found a gender/occupational group interaction. Study 2, conducted at an Irish tertiary care hospital (N = 892), found nurses felt at greater risk for all three types of abuse than did non-nurses. Further, women perceived themselves at greater risk for sexual harassment and verbal abuse than did men; the study found no gender difference regarding physical abuse. The analysis identified a gender/occupational group interaction for sexual harassment. The study considers methods of reducing perceived risk in regard to the research literature on abuse at work. 相似文献
