以甘肃省陇南市成县6所幼儿园301名农村幼儿及其母亲为研究对象,采用流调中心抑郁量表(CES-D)、母亲教养方式量表和Achenbach儿童行为量表(CBCL)分别考察母亲抑郁、母亲回应性和幼儿社交退缩的现状及相互关系。主要结果如下:(1)西北农村地区母亲抑郁发生率较高,父亲外出打工和贫困家庭的母亲抑郁发生率更高;(2)母亲抑郁与幼儿社交退缩行为显著正相关,母亲抑郁水平越高,幼儿社交退缩得分越高;(3)母亲敏感性和反应性与幼儿社交退缩显著负相关,母亲敏感性和反应性得分越高,幼儿社交退缩得分越低;(4)母亲反应性在母亲抑郁和幼儿社交退缩之间起部分中介作用。 相似文献

以儿童抑郁量表为研究工具,对小学3到4年级771名儿童进行了2年的追踪研究。采用潜类别增长模型和终端结局潜发展模型,分别考察了童年期儿童抑郁情绪发展的亚群组类型,以及儿童抑郁情绪的发展特征对观察期结束时抑郁情绪的预测作用。结果表明:(1)童年期儿童的抑郁情绪发展呈现出三种不同的亚类型,即抑郁高风险组、抑郁低风险组和抑郁自愈组,各类型组人数比例分别为9.6%、53.4%和36.8%;(2)童年期儿童抑郁情绪的初始水平及其发展变化率均可以显著预测观察期结束时的抑郁情绪状况。童年期儿童抑郁情绪的早期监测工作有着重要的实践意义。 相似文献

When witnesses at a trial offer testimony that is vivid, it may be more persuasive than the same testimony offered in a pallid manner. In this paper we elucidate three categories of variables (inferential, attentional/memorial, and affective) that are likely to mediate the effects of the vividness of testimony on jury judgments. These variables are then used to explain discrepant findings among mock juror experiments investigating vividness effects. Finally, we discuss the implications of vividness effects for the legal system. 相似文献

A battery of items testing oral stereognostic ability was individually presented to 168 children, 12 boys and 12 girls at each of seven age levels from 4-5 to 11-4. Age was significantly related to oral stereognostic scores; older subjects scored significantly higher than younger subjects. Sex was also significant; girls scored higher than boys. The interaction of age and sex was not significant. 相似文献

Harries and Stadler (1988) observed only a positive linear trend, with no curvilinear relationship, between heat and violence in their 1980–81 Dallas field data. When Cotton (1986) observed similar trends in his data, we noted that in fact the variance in violence increases with temperature (Bell & Fusco, 1986). We report here similar statistically significant heteroscedasticity in the Harries and Stadler data. We propose that both aggressive and escape tendencies increase with high ambient temperatures, such that in some circumstances aggression will decline under very hot and uncomfortable conditions. We conclude that the negative affect escape model of the temperature-aggression relationship is neither dead cold nor hot and bothered. 相似文献

The article explores the development of the relationship between monks and lay people within the newly established context of British Theravada Buddhism. Unlike their Asian counterparts, the British laity appear not to be interested in the traditional practice of ‘making merit’. The article draws out the implications of this feature of British Buddhism for a more general understanding of reciprocity in Theravada monk/ lay relationships. 相似文献

Discovering that participants who received therapy in a research project and were being debriefed in a therapy outcome study considered those assessment sessions therapeutic, the authors conclude that participants: (a) are aware of the research context, (b) have some idea about how it affected the treatment they got, and (c) see positive outcomes for taking part in the study. Assessment and treatment were not separated in the minds of some participants, as they had been in the mind of the researchers.This study was supported in part by National Institute on Drug Abuse grant #1R 18DA 1069232001. 相似文献

Body (ear) temperature of 14 subjects was lowered in order to examine its effect upon performance of a task requiring estimation of an interval of 60 s. Although there was some evidence that subjects counted more slowly at lower body temperatures, the inconsistency of the effect was such as to cast doubt on the hypothesis of a “biochemical clock” or “metabolic pacemaker” in the brain said to subserve human time estimation of brief intervals. 相似文献
