The present research reveals the bi-directional relationship between career-related control beliefs and strivings, and their predictive relationship with hours of gainful employment. Three waves of data of a longitudinal study of 532 graduating high school seniors from four ethnically diverse schools in the Los Angeles Unified School District were analyzed using structural equation modeling. The results show individuals?? career-related personal control beliefs in effort and social connections, but not in ability or luck, were significantly predictive of career-related control strivings 1?year later. Thus, only personal control beliefs in causal factors that are contingent on an individual??s primary control strivings to enact effects are predictive of active motivational engagement in pursuit of career-related goals. Regarding the inverse direction of influence (i.e., strivings predict beliefs), career-related control strivings were significantly predictive of career-related personal control beliefs in ability, effort, and social connections, but not luck, 1?year later. These results support the idea that active goal engagement creates an implemental mindset that optimistically biases individuals?? beliefs in their personal control over causal factors relevant to attaining a pursued career-related goal. In addition, the results show that career-related control strivings, but not career-related personal control beliefs, are significantly positively associated with the number of hours of gainful employment worked 1-year later, supporting a beliefs-strivings-outcome sequential relationship. 相似文献

Confirmational holism is central to a traditional formulation of the indispensability argument for mathematical realism (IA). I argue that recent strategies for defending scientific realism are incompatible with confirmational holism. Thus a traditional formulation of IA is incompatible with recent strategies for defending scientific realism. As a consequence a traditional formulation of IA will only have limited appeal. 相似文献

In three experiments we tested whether nostalgia bolsters meaning in life relative to two other modes of autobiographical thought: imagining a desired future experience and recalling a positive past experience. In Experiment 1 participants thought about a nostalgic or desired future experience and then completed a presence of meaning scale. Thinking about a nostalgic (compared to desired future) experience increased perceived presence of meaning. In Experiment 2 we examined whether nostalgia can additionally reduce the search for meaning. Participants thought about a nostalgic, desired future or recent positive experience, and then completed a search for meaning scale. Nostalgia, relative to both comparison conditions, decreased the search for meaning. Finally we tested whether, by virtue of its capacity to increase meaning, nostalgia can mitigate threats to meaning. In Experiment 3 participants were exposed to either absurd or representational art, under the guise that they would later have to interpret its meaning, and then thought about either a nostalgic or a recent positive experience. Meaning was subsequently measured. The absurd art interpretation condition decreased the perceived presence of meaning but nostalgic reflection attenuated this effect. 相似文献

Mandik understands color-consciousness conceptualism to be the view that one deploys in a conscious qualitative state concepts for every color consciously discriminated by that state. Some argue that the experimental evidence that we can consciously discriminate barely distinct hues that are presented together but cannot do so when those hues are presented in short succession suggests that we can consciously discriminate colors that we do not conceptualize. Mandik maintains, however, that this evidence is consistent with our deploying a variety of nondemonstrative concepts for those colors and so does not pose a threat to conceptualism. But even if Mandik has shown that we deploy such concepts in these experimental conditions, there are cases of conscious states that discriminate colors but do not involve concepts of those colors. Mandik's arguments sustain only a theory in the vicinity of conceptualism: The view that we possess concepts for every color we can discriminate consciously, but need not deploy those concepts in every conscious act of color discrimination. 相似文献

The examination of a student’s racial identity beliefs along with the extent to which being Black is a central part of his
or her self-concept provides a novel, insightful approach to understanding the relationship between racial identity and academic
achievement (Chavous et al., 2003,). Using Sellers et al. (1998a) Multi-dimensional Model of Black Identity (MMBI) as a framework,
this study investigated racial centrality, public regard and private regard beliefs in relation to the grade point average
of African–American high-school students. A total of 289 African–American students from a large urban district participated
in this study. Cluster analyses conducted on the three subscales of the MMBI on separate samples of 9th and 12th grade students
replicated three of four racial identity profile groups previously identified by Chavous et al. (2003). Additionally, among
both 9th and 12th grade students, Alienated students achieved significantly higher grade point averages than did Idealized students. 相似文献

An experimental study of the physical and psychological effects of aerobic exercise on schoolchildren 总被引:1,自引:0,他引:1
This study compared the physical and psychological effects of running to those of the normal physical education program of activities among 154 fourth, fifth, and sixth graders who were randomly assigned to conditions within a true experimental design. The running program consisted of three 30-min sessions per week for 12 weeks in lieu of attendance in regular physical education classes. Findings showed that although boys tended to run faster than girls overall and that older children run faster than younger children, running-program participants performed better on an 800-m run, had lower pulse rates, and performed better on a test of creativity than did regular physical education participants. Running boys had less body fat, and running girls had more creative involvement in class. No differences were found on 50-m dash performance or perceptual skill. On total behavior, girls were more self-controlled than boys, and self-concept tended to become less positive with increased grade level. Running performance for 800 m persisted for 5 months among boys in the treatment, but not among girls. Running was judged effective for enhancing the cardiorespiratory health and creativity of school children. 相似文献
