Rare or low probability targets are detected more slowly and/ or less accurately than higher probability counterparts. Various proposals have implicated perceptual and response-based processes in this deficit. Recent evidence, however, suggests that it is attentional in nature, with low probability targets requiring more attentional resources than high probability ones to detect. This difference in attentional requirements, in turn, suggests the possibility that low and high probability targets may have different susceptibilities to attention capture, which is also known to be resource-dependent. Supporting this hypothesis, we found that, once attentional resources have begun to be engaged by detection processes, low, but not high, probability targets have a reduced susceptibility to capture. Our findings speak to several issues. First, they indicate that the likelihood of attention capture occurring when a given task-relevant stimulus is being processed is dependent, to some extent, on how said stimulus is represented within mental task sets. Second, they provide added support for the idea that the behavioural deficit associated with low probability targets is attention-based. Finally, the current data point to reduced top-down biasing of target templates as a likely mechanism underlying the attentional locus of the deficit in question.  相似文献

Fly-in fly-out work patterns have become an integral part of employment in the Australian resource sector. When attachment to parents is disrupted by a parent working away from home on a regular basis, young people’s feelings of connection to their family may be impacted, as well as their mental and emotional well-being compromised. The objective of this study was to explore the mediation of parental presence and family connectedness on the association between fly-in fly-out employment and adolescent well-being. A cross-sectional survey of over 3,000 Grades 5–10 students from 40 Perth West Australian metropolitan and rural schools identified 618 students whose parents were involved in fly-in fly-out employment. Multi-level mediation analysis showed that the negative relationship between fly-in fly-out status and adolescent depressive symptoms and emotional and behavioural difficulties was fully or partially mediated by parent presence and family connectedness, controlling for both student and school level demographics. The intermittent absence/presence of fly-in fly-out employment patterns appears to create challenges for workers and their families, not experienced by non-fly-in fly-out families.This study highlights the importance of strengthening family connections within fly-in fly-out households. Suggestions have been made to help fly-in fly-out parents to stay in touch with their families.  相似文献

African‐American adolescents exposed to neighborhood disadvantage are at increased risk for engaging in problem behavior and academic underachievement. It is critical to identify the mechanisms that reduce problem behavior and promote better academic outcomes in this population. Based on social disorganization and socioecological theories, the current prospective study examined pathways from parental monitoring to academic outcomes via externalizing behavior at different levels of neighborhood disadvantage. A moderated mediation model employing maximum likelihood was conducted on 339 African‐American students from 9th to 11th grade (49.3% females) with a mean age of 14.8 years (SD ± 0.35). The results indicated that parental monitoring predicted low externalizing behavior, and low externalizing behavior predicted better academic outcomes after controlling for externalizing behavior in 9th grade, intervention status, and gender. Mediation was supported, as the index of mediation was significant. Conversely, neighborhood disadvantage did not moderate the path from parental monitoring to externalizing behavior. Implications for intervention at both community and individual levels and study limitations are discussed.  相似文献

For Kant, Aristotle's categories are arbitrary but brilliant and they do not ultimately correspond to extramental reality. For Aquinas, however, they are rational divisions of extramental being. In this perennial and ongoing dispute, the various positions seem to dissolve upon delving into the particulars of any one category. If, however, the categories are divisions of extramental being, it should be possible to offer plausible accounts of particular categories. I offer Aquinas's unstudied derivation of quality as a test case to see how one could hold, and how Aquinas did hold, to a realism about Aristotle's categories at a highly specific level. Although Aristotle divides quality into four species and some further subspecies, unlike Aquinas, he offers no reasons for these divisions. For Aquinas each accident is a particular mode of existing, that is, it is a particular way that an accident exists in a substance. In the case of quality, this mode of existing follows substantial form and its real extramental causes or effects further divide it into four species. Aquinas's account is both compelling and original, inspired by Aristotle but also un-Aristotelian. The paper concludes by comparing Aquinas's account of quality with the best extant account of Aristotle's quality, namely, Paul Studtmann's.  相似文献

Psychological capital is a positive psychological state that influences employees’ behaviors and attitudes. Research has only recently begun to examine the phenomenon as a shared psychological team state. The purpose of this research is to examine the mediating role of team psychological capital in the relationship between learning climate and outcomes at the individual and team levels. The findings, which were carried out among 82 school management teams, indicated a positive relationship between learning climate and the team’s psychological capital, and between the team’s psychological capital and the individual’s job satisfaction and the team’s organizational citizenship behavior (OCB). It was also found that team’s psychological capital mediates the relationship between the team’s learning climate and job satisfaction, and between learning mechanisms and the team’s OCB. The findings might encourage research into psychological capital as a team phenomenon and encourage decision-makers to develop ways of reinforcing psychological capital among teams.  相似文献
