In this study, we examined relations between kindergartner's emotional security, task involvement and achievement and teacher's supportive presence in a cognitive training setting, in which the familiarity of the teacher was varied. Participants were 48 kindergarten children (mean age=51.65 months); 16 children were trained by their regular teacher (experimental group 1), 16 by a less familiar teacher (experimental group 2) and 16 received no training (control group). In three training sessions, children worked in pairs on a new categorization and recall task. Trained observers rated children's emotional insecurity and task involvement and teacher's supportive presence. Furthermore, spontaneous recall during the training was assessed. In addition, categorization and spontaneous recall was measured in various test sessions. Children's emotional insecurity during training negatively affected involvement. Involvement on its turn positively influenced spontaneous recall during training. In addition, emotional insecurity had a direct negative effect on spontaneous recall in a test situation. No effect of familiarity or supportive presence of the teacher on emotional security was found. Training conditions did not affect test performances. Findings suggest that children's involvement is important for learning and that experiences of emotional insecurity may negatively affect task involvement, test performance and eventually school achievement. Teachers in general seem capable of providing children with some sense of security. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

关于RB效应加工水平的研究 总被引:1,自引:1,他引:0
本研究采用正字法相似的汉字作为实验材料考察了RSVP任务中的RB效应的加工水平。研究发现:(1)RB效应不仅出现在重复字中,而且也出现在正字法相似字中,但其强度弱于重复字中的RB效应;(!)在正字法相似的汉字加工中.由于加工相似字的识别错误发生在语义加工之前的阶段.因此.RB效应的产生点可能出现在记忆加工之前的知觉阶段。 相似文献

Dzhafarov and Colonius (Psychol. Bull. Rev. 6 (1999)239; J. Math. Psychol. 45(2001)670) proposed a theory of Fechnerian scaling of the stimulus space based on the psychometric (discrimination probability) function of a human subject in a same-different comparison task. Here, we investigate a related but different paradigm, namely, referent-probe comparison task, in which the pair of stimuli (x and y) under comparison assumes substantively different psychological status, one serving as a referent and the other as a probe. The duality between a pair of psychometric functions, arising from assigning either x or y to be the fixed reference stimulus and the other to be the varying comparison stimulus, and the 1-to-1 mapping between the two stimulus spaces X and Y under either assignment are analyzed. Following Dzhafarov and Colonius, we investigate two properties characteristic of a referent-probe comparison task, namely, (i) Regular cross-minimality—for the pair of stimulus values involved in referent-probe comparison, each minimizes a discrimination probability function where the other is treated as the fixed reference stimulus; (ii) Nonconstant self-similarity—the value of the discrimination probability function at its minima is a nonconstant function of the reference stimulus value. For the particular form of psychometric functions investigated, it is shown that imposing the condition of regular cross-minimality on the pair of psychometric functions forces a consistent (but otherwise still arbitrary) mapping between X and Y, such that it is independent of the assignment of reference/comparison status to x and to y. The resulting psychometric differentials under both assignments are equal, and take an asymmetric, dualistic form reminiscent of the so-called divergence measure that appeared in the context of differential geometry of the probability manifold with dually flat connections (Differential Geometric Methods in Statistics, Lecture Notes in Statistics, Vol. 28, Springer, New York, 1985). The pair of divergence functions on X and on Y, respectively, induce a Riemannian metric in the small, with psychometric order (defined in Dzhafarov & Colonius, 1999) equal to 2. The difference between the Finsler-Riemann geometric approach to the stimulus space (Dzhafarov & Colonius, 1999) and this dually-affine Riemannian geometric approach to the dual scaling of the comparison and the reference stimuli is discussed. 相似文献

课堂情境与任务难度对学业求助之影响的研究 总被引:1,自引:0,他引:1
本实验以初二年级学生为被试,研究了课堂情境、任务难度、学业成绩以及性别对学业求助的影响。结果表明:(1)任务关注的课堂情境比自我关注的课堂情境导致更多的求助行为,求助方式上,则倾向于工具性求助。(2)完成难度适中学习任务的学生比完成高难度学习任务的学生表现出更多的求助行为,求助方式上,则倾向于工具性求助。(3)在任何条件下,成绩好的学生都比成绩差的学生更善于作工具性求助。(4)从总体来看,初二学生的求助行为不存在性别差异。但在自我关注的课堂中,男生比女生表现出更多的回避求助。 相似文献

任务转换是研究执行功能的常用范式。任务转换通常伴随着转换代价:执行转换任务比重复任务的反应时更长、错误率更高。转换代价可能反映了任务设置重构(重构理论), 也可能表明任务之间存在干扰(干扰理论)。与任务线索范式相比, 自主任务转换范式更具生态效度, 而且不仅能获得转换代价这个传统结果, 还引入了任务选择比例、任务转换率等新指标, 其结果倾向于支持重构理论。此外, 新近研究指出自主任务转换可能也包含干扰的作用。未来, 应通过进一步改进实验范式等方法, 实现两大理论的融合。 相似文献

Objects with curved contours are generally preferred to sharp‐angled ones. In this study, we aim to determine whether different presentation times influence this preference. We used images of real objects (experiment 1) and meaningless novel patterns (experiment 2). Participants had to select one of two images from a contour pair, curved and sharp‐angled versions of the same object/pattern. With real objects, the preference for curved versions was greatest when presented for 84 ms, and it faded when participants were given unlimited viewing time. Curved meaningless patterns were preferred when presented for 84 and 150 ms. However, in contrast to real objects, preference for meaningless patterns increased significantly in the unlimited viewing time condition. Participants discriminated poorly between the two versions (curved and sharp‐angled) of the meaningless patterns in the 84‐ and 150‐ms presentations (experiment 3). Therefore, in short times with meaningless patterns, participants selected mostly the curved version without being aware of the difference. In conclusion, presentation time, type of stimulus, and their interaction influence preference for curvature. 相似文献

Implicit and explicit attitudes correlate under certain conditions and researchers are interested in the moderating factors of this relationship. This paper explored the role of socially desirable responding in this relationship by testing the hypothesis that impression management (IM; i.e., deliberate response modification) and self‐deceptive enhancement (SDE; i.e., positive self‐bias) play moderating roles in the relationship of implicit–explicit attitudes toward asylum seekers in Australia. Seventy‐four students responded to a battery of measures and the results revealed that IM (but not SDE) moderated this relationship to the extent that higher IM scores weakened the correspondence between implicit and explicit attitude scores. This suggests that attitudes toward asylum seekers might be susceptible to socially desirable response tendencies and in combination with the finding that IM was negatively related to explicit attitudes, it is argued that self‐presentation concerns result in the deliberate attenuation of reported negative explicit attitudes. 相似文献

Based on positive organizational behavior, this study aimed to explore the impact of psychological capital (PsyCap) on task performance, organizational citizenship behaviors, affective commitment, and job satisfaction among army aircraft mechanics. Data was obtained from 260 aircraft mechanics working in various Turkish Army aviation units. The hypotheses were tested using a series of hierarchical regressions. The results indicated that those with higher PsyCap are more likely to depict task performance, engage in highly extra-role behaviors, be more committed to their organizations, and be highly satisfied with their jobs that are advantageous to army aviation settings. The authors concluded that promoting the levels of PsyCap could be effective in elevating aircraft mechanics’ work attitudes and behaviors. Military aviation units are encouraged to establish human resource development programs to foster the PsyCap of their soldiers, which in turn, enhances crucial work attitudes. 相似文献
