认知方式与幼儿部分遮挡绘画关系的研究   总被引:2,自引:1,他引:2  
本研究考察了5—6岁儿童不同认知方式对部分遮挡绘画任务的影响。实验设定不同形式的误导情境,共有两部分组成。研究结果表明:1.儿童绘画表征水平的发展存在个别差异。2.在误导情境下,场独立儿童比场依存儿童能保持较稳定的策略选择倾向。3.画两个相同物体的遮挡要难于画两个不同物体的遮挡。4.在符号概念编码和空间编码中间存在着一些过渡形态。  相似文献

FOK判断等级及其准确性的实验研究   总被引:3,自引:1,他引:3  
通过实验集中探讨了FOK判断等级及其准确性的影响因素。实验以中文字串为学习材料,使用组内设计的实验方法研究了被激活信息的量和强度对FOK等级及准确性的影响。实验结果表明:FOK判断的等级是由被激活信息的总量决定的,和被激活信息的正确与否无关;FOK判断的准确性是由被激活信息的强度决定的;且二者之间是有内在联系的。  相似文献

It is often believed that helping behaviors benefit the recipients at the expense of the performers. However, we propose that costly helping behaviors could alleviate feelings of physical burden experienced by the performers. In support of the proposal, we found in five studies that both imaginary and real helping behaviors led the performers to perceive physically challenging tasks as less demanding (Studies 1, 2, 3, 5), such as perceiving a steep mountain road as less steep (Study 2), a heavy carton as lighter (Study 4), and a long path as shorter (Study 5). These results challenge the conventional wisdom that helping behaviors always come at the cost of the helper and corroborate a growing body of literature showing that helping others could benefit the performer.  相似文献

通过对经典四卡问题呈现方式的改进,逐一呈现与命题对应的检验证据,要求被试判断每一证据在命题检验中的作用。结果表明:(1)"证真偏向"依然存在,但从正确率来看,顺证真与顺证伪没有显著差异;(2)发现了显著的顺序效应,与逆向检验相比,顺向检验有更高的正确率与更短的反应时;(3)被试加工与命题"无关联"刺激时存在明显困难,其正确率显著较低。这些结果说明个体在判断不同证据对命题检验的作用时会受到命题内在方向性的影响,个体可能会采用一些固有推理图式以及简单的匹配策略解决问题。  相似文献

选取36名大学生被试,采用探针检测的方法和逐句阅读范式,考察被试阅读中文材料时走神对阅读正确率和阅读时间的影响。结果发现:(1)中文阅读中出现走神的时间占34.80%;(2)走神会影响阅读理解,降低阅读理解正确率;(3)走神会导致阅读时间变慢。这些发现均证实走神对中文阅读绩效有影响,降低阅读理解正确率和减缓阅读时间。  相似文献

本研究通过两个实验考察幼儿是否在博弈任务中表现出对陌生人的信任行为,同时考察可能对幼儿的信任产生影响的因素,包括个体认知因素(观点采择)和环境因素(负性反馈和代际传递)。研究对189名4~6岁幼儿及其家长进行多种任务的测量。实验一通过修订Evans和Krugger(2011)的信任博弈任务,考察幼儿在匿名信任博弈中的信任行为,结果发现与4岁幼儿相比,6岁幼儿对他人的信任更低;实验二考察了幼儿信任的影响因素,结果发现,幼儿在得到负性反馈结果后再次进行信任博弈任务时,他们对他人的信任比前次有所降低,6岁幼儿对他人返还数量的预期比4岁幼儿下降程度更大;6岁幼儿的信任行为(第一次给出意愿)与观点采择能力显著相关;6岁幼儿的信任水平与家长的信任水平显著相关。  相似文献

There is little knowledge available concerning psychopathic traits in Asian adolescents; a lack of a suitable measurement instrument for assessing psychopathy in Asian societies may account for this. This study aimed to validate a widely used scale in the West — the Antisocial Process Screening Device (APSD) — in Singaporean school-based and at-risk adolescents. Using an exploratory factor analysis (EFA) and a confirmatory factor analysis (CFA), this study examined the two-factor (i.e., grandiose-manipulative/impulsive traits and callous-unemotional traits) and three-factor (i.e., grandiose-manipulative traits, impulsivity, and callous-unemotional traits) models of the APSD in 1027 school-based and 113 at-risk adolescents. School samples are adolescents from three secondary schools, while at-risk samples are adolescents who manifest different types of delinquent behaviors and are either placed in more structured settings or need closer supervision although they have not violated the law. Gender invariance was further tested in the school-based sample by conducting a multigroup CFA. The convergent validity of the APSD was also investigated in the school-based sample. For the school-based adolescents, the APSD revealed that the three-factor model provided a superior fit over the two-factor model and the factorial invariance across gender. Significant relationships between the three dimensions of the APSD and aggression and delinquency support the convergent validity of the APSD. As for the at-risk adolescents, both the two- and three-factor models were acceptable, but the two-factor model was preferred as it was parsimonious and it aligned with the conceptualized characteristics of psychopathic traits. Findings suggest that the APSD is a reliable and sound instrument for measuring psychopathic traits in Asian school-based and at-risk adolescents.  相似文献

A sequel to the previous article “Roots of Excellence: The Releasing Effect of Individual Potentials through Educational Cultural Intervention in a Chinese School” (in press), the present study is on the unexpected reversal phenomena in the process of cultural intervention. The goal of the intervention is to construct the dynamics of Jiti (well-organized collective in Chinese) through creative activities to promote students’ development. In the intervention, the releasing effect (Wu et al. 2016) emerged as well, but the teacher’s concern about worsening discipline and academic performance evoked and reinforced his habitual notions and practices of education, turning the joint activities into a way of strengthening discipline. The energy that had been discharging at the beginning of the intervention was inhibited, so that many more problematic behaviors took shape. The whole class formed an inhibitory atmosphere, within which pupils formed self-defensive regulation strategies. By comparing with the productive collective in which intervention was effective and analyzing this unexpected reversal process, we can not only see pupils’ self-construction status in the inhibitory culture but illuminate the formation of the teacher’s resistance to educational and cultural transformation as well. Resistance is originated from teachers not being able to interpret pupils’ inner developmental needs but instead anxious about the ongoing problems.  相似文献

The purpose of this study was to assess the reliability and validity of a single-item measure of Usual Physical Activity and to assess its usefulness as a physical activity tool for perimenopausal women. 188 perimenopausal women participated (age: M = 47 yr., SD = 3; range = 40-55). Data were collected using the Women's Health Assessment Scale, the Physical Activity Questionnaire, the Perimenopause-related Quality of Life Scale, a health history and demographic questionnaire, and the rater. Scores were stable over a 2-wk. interval. Convergent validity was supported by a correlation of .66 between ratings on Usual Physical Activity and the Physical Activity Questionnaire. Concurrent validity was supported by the association of the rating of Usual Physical Activity with three parameters of Body Mass Index, psychosomatic symptoms, and perimenopause related quality of life, known to be associated with physical activity. Highly active women had a lower Body Mass Index than less active and inactive women. Active women tended to report fewer and less distressing psychosomatic symptoms and better quality of life. These findings support the use of rating of Usual Physical Activity to classify perimenopausal women into categories of physical activity.  相似文献

We investigated the regulation of sequential action using a new paradigm. Participants learned a sequence of seven stimulus categories and then monitored for them during successive displays. All displays were instances of these categories, presented in pseudorandom order. On each trial, participants monitored for an instance of Category 1, pressed a key on a computer keyboard, then monitored for an instance of Category 2, pressed a key on the keyboard, and so on for all seven categories. Thus, a perfect trial contained exactly seven responses. Intrusion errors were classified as a function of ordinal distance from the current serial position ( n ). Fewer intrusion errors were made at near serial positions than at far ones, suggesting a gradient of lateral inhibition. In addition, more intrusions were made on n + 1 categories than n − 1 categories, suggesting greater availability of intended than completed goals. In accord with current models of sequential action, the results indicate lateral and self-inhibition as important mechanisms in regulation of sequential action.  相似文献
