数学学习不良的研究及趋势 总被引:12,自引:0,他引:12
认知心理学、神经心理学的研究发现了数学学习不良(MD)儿童的3种基本算术技能障碍:语义记忆型MD、程序型MD、视觉空间型MD,并对它们的机制和特征做了考察.近年来对MD儿童较高级数学问题解决的研究呈现如下特点:参与到该研究的领域很多;研究所涉及的认知和非认知因素增多;教学干预研究大量出现.目前MD研究在辨别MD儿童、缺陷的概念以及神经心理学解释上面临挑战.因此该研究领域的趋势是从发展的、整体的视角来考察影响MD的各种因素,并注意各种方法的革新和结合. 相似文献

This study explored whether a source-monitoring training (SMT) procedure, in which children distinguished between events they recently witnessed versus events they only heard described, would help 3- to 8-year-olds to report only experienced events during a target interview. Children (N = 132) who witnessed science demonstrations and subsequently heard their parents describe nonexperienced events received SMT before or after a forensic-style interview. SMT reduced the number of false reports that 7- and 8-year-old children reported in response to direct questions but had no impact on the performance of younger children. Combined with earlier results, these data suggest a transition between 3 and 8 years of age in the strategic use of source-monitoring information to support verbal reports, such that only 7- and 8-year-olds generalize training to a difficult memory task that does not include mention of specific alternative sources. 相似文献

A series of experiments examined children's recognition of animals by their features (Parts) and by the relative scale of the parts (Wholes). They were asked to identify the correct picture of an animal they could name from the original plus two computer-generated alternatives. We examined the developmental trends associated with upright (Studies 1 and 3) and inverted presentations (Study 3). Both experiments confirmed children's superior ability in dealing with the recognition of animal Parts over animal Wholes, especially for the younger ages tested (6- and 10-year-olds). It was not until the ages of 15-16 that children demonstrated equal performance on Whole and Part items. The late acquisition of animal Whole recognition is compared to the late acquired configural skills proposed for face recognition. 相似文献

The present paper examines test anxiety from a cross-cultural perspective with specific reference to the Indian and American cultures. The construct of test anxiety has been examined in many cultures all over the world. In this review, the importance of understanding and incorporating contextual factors in cross-cultural research is emphasized. Moreover, some of the methodological issues related to investigating culture-behavior relationship are discussed. Specifically, the derived-etic approach for conducting cross-cultural research is espoused. Then, research findings from western, cross-cultural, and Indian studies on test anxiety are reviewed. Consistent with the individualistic orientation of the western society, much of the research in the western world has adopted a de-contextualized approach. Inasmuch as many of the cross-cultural and Indian studies on test anxiety have their roots in western research, they have ignored the cultural context as well. To address this void, contextual variables relevant to test anxiety in the Indian setting are examined and hypotheses regarding the nature of test anxiety in Indian children are proposed. Finally, a research agenda is presented to examine these hypotheses using a derived-etic approach. 相似文献

The hypothesis that parental alcoholism and co-occurring antisocial behavior would be indirectly linked to child externalizing behavior problems through child lack of control, current levels of parent depression, family conflict, and parent–child conflict was tested using manifest variable regression analysis. Participants were a community sample of 125 families with an alcoholic father and 83 ecologically matched but nonsubstance abusing families involved in the first 2 waves of an ongoing longitudinal study (with 3 years between each wave). All families had a biological son who was 3–5 years old at study onset. Results revealed that child lack of control mediated the relation between paternal alcoholism and the son's subsequent externalizing behavior problems. Family conflict was a significant mediator of maternal and paternal lifetime antisocial behavior effects and father–son conflict mediated paternal lifetime antisocial behavior effects. Study implications are discussed within the context of parental socialization of antisocial behavior. 相似文献

Anger in children has received a lot of attention. This article is a review of several rational-emotive behavioral interventions for children struggling with anger problems. The first step discussed in this article involves helping children learn to recognize their internal signals that they are becoming angry. Children can be taught that there are certain physiological events that occur immediately preceding anger. Another important component of anger management involves the use of distraction, in which children are encouraged to substitute a happy or funny mental image to interrupt the anger producing thoughts. Finally, a detailed analysis of rational-emotive imagery is provided for children needing more extensive interventions with their anger problems. 相似文献

This paper aims to investigate the syntactic comprehension of reversible relative clauses in a group of eight Greek children with specific language impairment (SLI) and two control groups of normally developing children matched on chronological and language age, respectively. An experiment using an acting out procedure was undertaken. Group analysis revealed that SLI children's performance is qualitatively different than that of both control groups. Interpreting the data, processes involved in syntactic comprehension are taken into consideration. It is claimed that processing demands impede SLI children's performance due to a deficit in their competence grammar. 相似文献

The Children's Attributional Style Interview: Developmental Tests of Cognitive Diathesis-Stress Theories of Depression 总被引:5,自引:0,他引:5

This paper presents an initial assessment of the Children's Attributional Style Interview (CASI), a newly designed measure for assessing attributional style in young children (age 5 and up). The CASI was used to conduct prospective tests of the reformulated helplessness (L. Y. Abramson, M. Seligman, & J. Teasdale, 1978) and the integrated hopelessness/self-esteem (G. I. Metalsky, T. E. Joiner, Jr., T. S. Hardin, & L. Y. Abramson, 1993) theories of depression in a sample of 147 5–10-year-old children. For comparison, the same tests were also conducted with the Children's Attributional Style Questionnaire-Revised (CASQ-R; N. J. Kaslow & S. Nolen-Hoeksema, 1991), a commonly used measure for assessing attributional style in older children (age 8 and up). The CASI evidenced support of the reformulated helplessness theory and partial support of the integrated hopelessness/self-esteem theory. The CASI also demonstrated good internal consistency. Thus, our findings provide initial support for the CASI as a methodologically sound measure of attributional style for children as young as 5 years old. Although preliminary, our findings also suggest possible developmental differences in how attributional style interacts with self-esteem and negative life stress. The CASI should prove to be a useful tool in furthering the understanding of the origins and development of attributional style in childhood, as well as its contribution to the understanding of the development and prevention of depressive symptomatology in children. 相似文献

言语产生中的词长效应 总被引:9,自引:5,他引:4
采用图片命名方法考察言语产生中的词长效应,并进而分析语音计划的单位和序列性。选取能同时用单音节(如“羊”)和双音节(“山羊”)命名的图片作刺激材料,发现双音节命名明显慢于单音节命名,这种效应既表现在首音节型(如“花”与“花朵”),也表现在尾音节型(如“羊”与“山羊”)刺激材料上。研究结果支持语音编码从左到右、系列提取和双音节词的词音计划单位大于单音节词的观点。该文还对图片命名中的频率效应进行了事后分析。 相似文献
