探讨了再认条件下元监测判断的影响因素。以中文双字词对作为实验材料 ,安排在不同预先呈现时间、有无进行有意识记 ,以及不同识记遍数等条件下进行元监测判断。用计算机随机呈现项目 ,再认之前先让被试做元监测判断 ,判断是否是记过的项目的把握程度 ,再对有意识记过的项目做迫选再认 ,作为标准测验 ,以验证元监测判断的准确性。结果是预先呈现时间长、有意识记过的和识记遍数多的项目 ,对其再认的反应时较短 ,相应的元监测判断等级也较高 ;对只看而未有意记过的项目的判断是呈现时间长的判断等级反而低于呈现时间短的。此结果表明 ,再认条件下 ,元监测判断的等级的高低与识记项目的激活程度有关 相似文献

Associations between first-year maternal employment and mother—and youth-reported externalizing behavior at age 15 were examined paying attention to potential mediating roles of home and child care environments by 36?months, effortful control at 54?months, and externalizing behavior at 54?months and middle childhood. We used data from the NICHD Study of Early Child Care and Youth Development (n?=?922 non-Hispanic White children) which is a prospective birth cohort study that followed children from birth to age 15. Full-time first-year maternal employment was associated with higher levels of externalizing behavior at age 15 through higher maternal depressive symptoms by 36?months, lower effortful control at 54?months, and higher externalizing behavior at 54?months and middle childhood. Part-time first-year maternal employment was not associated with higher externalizing behavior at age 15. 相似文献

Attention, the mechanism by which a subset of sensory inputs is prioritized over others, operates at multiple processing stages. Specifically, attention enhances weak sensory signal at the perceptual stage, while it serves to select appropriate responses or consolidate sensory representations into short-term memory at the central stage. This study investigated the independence and interaction between perceptual and central attention. To do so, I used a dual-task paradigm, pairing a four-alternative choice task with a visual search task. The results showed that central attention for response selection was engaged in perceptual processing for visual search when the number of search items increased, thereby increasing the demand for serial allocation of focal attention. By contrast, central attention and perceptual attention remained independent as far as the demand for serial shifting of focal attention remained constant; decreasing stimulus contrast or increasing the set size of a parallel search did not evoke the involvement of central attention in visual search. These results suggest that the nature of concurrent visual search process plays a crucial role in the functional interaction between two different types of attention. 相似文献

What makes category labels different from feature labels in predictive inference? This study suggests that category labels tend to make inductive reasoning polarized and homogeneous. In two experiments, participants were shown two schematic pictures of insects side by side and predicted the value of a hidden feature of one insect on the basis of the other insect. Arbitrary verbal labels were shown above the two pictures, and the meanings of the labels were manipulated in the instructions. In one condition, the labels represented the category membership of the insects, and in the other conditions, the same labels represented attributes of the insects. When the labels represented category membership, participants’ responses became substantially polarized and homogeneous, indicating that the mere reference to category membership can modify reasoning processes. 相似文献

Data from approximately 14,000 children in the Early Childhood Longitudinal Survey--Kindergarten Cohort were analyzed to examine the associations between children's immigrant status and their academic trajectories from kindergarten to 3rd grade, with particular attention to the effects of school environments. Growth curve modeling results indicated that most children of Latin American origin improved their reading and math scores faster than non-Hispanic White children, thus narrowing their initial score gap and sometimes even surpassing White children by 3rd grade. In contrast, although they maintained higher reading and math scores, children from East Asia and India showed decreasing scores over time, which tended to narrow their initial score advantage over non-Hispanic White children. School-level factors accounted partially for these differences. Particularly in terms of the academic trajectories, children of Latin American origin responded more to school-level factors than did children of Asian origin, who responded more to child and family background, with the exception of children from Vietnam, Thailand, Cambodia, and Laos, who responded more to school-level factors. Simulation results point to the importance of school resources for the academic trajectories of children of immigrants. 相似文献

Many traditional conjoint representations of binary preferences are additively decomposable, or additive for short. An important generalization arises under rank-dependence, when additivity is restricted to cones with a fixed ranking of components from best to worst (comonotonicity), leading to configural weighting, rank-dependent utility, and rank- and sign-dependent utility (prospect theory). This paper provides a general result showing how additive representations on an arbitrary collection of comonotonic cones can be combined into one overall representation that applies to the union of all cones considered. The result is applied to a new paradigm for decision under uncertainty developed by Duncan Luce and others, which allows for violations of basic rationality properties such as the coalescing of events and other framing conditions. Through our result, a complete preference foundation of a number of new models by Luce and others can be obtained. We also show how additive representations on different full product sets can be combined into a representation on the union of these different product sets. 相似文献
