研究旨在探讨个体分类倾向的发展趋势与影响因素.实验一采用图片、文字两种方式呈现实验材料,并使用不同指导语.要求被试选择三个事物中关系更近的两个.结果表明,成人比儿童具有更显著的按照主题分类的倾向,实验材料的呈现方式对于被试分类倾向没有显著影响.实验二进一步考察了分类倾向的发展轨迹,随着年龄增长,个体按照主题划分事物的倾向增强,由倾向于按照分类学规则向按照主题分类的转变可能发生在小学低中年级之间. 相似文献

This study of 598 7th grade students of Mexican origin examined the role of traditional cultural values as a mediator of the
effects of immigrant status, Mexican cultural orientation and Anglo cultural orientation on adolescent externalizing behavior
and academic engagement. Immigrant status of adolescents and their maternal caregivers uniquely predicted increased Mexican
cultural orientation and decreased Anglo cultural orientation, and both Mexican and Anglo cultural orientation related positively
to adolescents’ endorsement of traditional cultural values. Endorsement of traditional cultural values related, in turn, to
decreased externalizing behaviors and increased academic engagement and these findings were replicated across adolescent and
teacher report of these two outcomes. Tests of mediation provided further evidence to support these pathways. Findings support
the central importance of traditional cultural values as a protective resource that explains why immigrant youth exhibit fewer
externalizing problems and increased academic engagement when compared to their second and third generation peers. 相似文献

Social relations in the workplace are one of the main sources of risk for the onset of mobbing. In this work, we analyzed, through the perceived social climate, the influence of interpersonal relations on the characterization of the processes of mobbing, in a sample of local police (N = 235). In particular, the policemen and women's opinions of the quality of the personal relations among the group members and the treatment they receive from the command posts were assessed. The results of the study show that the development of guidelines of social interaction based on discrimination and abuse of authority are predicting variables of mobbing in this group. 相似文献

为了说明学龄儿童心理理论与执行功能的关系,研究采用失言理解、威斯康星卡片分类和汉诺塔任务分别考察了90名7—9岁儿童的心理理论和执行功能。结果表明,失言理解与抑制-转换能力相关显著(r=0.34,P〈0.01),但是与计划能力相关不显著(r=0.06,P〉0.05)。在控制年龄后,失言理解与抑制-转换能力的相关仍然显著(r=0.29,P〈0.05)。研究结果说明,学龄儿童心理理论与执行功能的相关模式与学龄前儿童完全一致,提示心理理论与执行功能的相关关系从学龄前延续到了学龄阶段。 相似文献

The present research investigated the moderating role of diversity beliefs with the aim of reconciling inconsistent findings regarding the impact of group boundary permeability on attitudes toward outgroup. In Study 1, all variables were measured with self‐report scales completed by Chinese participants. In Study 2, diversity beliefs were manipulated by randomly assigning Chinese participants to a high or low diversity belief condition. In Study 3, we replicated the moderating model with American participants. Results of all three studies indicated that diversity beliefs moderated the relationship between group boundary permeability and attitudes toward outgroup. Individuals with high diversity beliefs held more positive attitudes toward the outgroup when the group boundary was permeable (vs. impermeable). Conversely, individuals with low diversity beliefs held more negative attitudes toward the outgroup when the group boundary was permeable (vs. impermeable). These findings suggest that when the inflow of the outgroup members is inevitable, attitudes toward the outgroup may be effectively improved by increasing diversity beliefs. 相似文献

The ameliorating effect of oroxylin A on scopolamine-induced memory impairment in mice 总被引:2,自引:0,他引:2

Oroxylin A is a flavonoid and was originally isolated from the root of Scutellaria baicalensis Georgi., one of the most important medicinal herbs in traditional Chinese medicine. The aim of this study was to investigate the ameliorating effects of oroxylin A on memory impairment using the passive avoidance test, the Y-maze test, and the Morris water maze test in mice. Drug-induced amnesia was induced by administering scopolamine (1 mg/kg, i.p.) or diazepam (1 mg/kg, i.p.). Oroxylin A (5 mg/kg) significantly reversed cognitive impairments in mice by passive avoidance and the Y-maze testing (P<.05). Oroxylin A also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze (P<.05). Moreover, the ameliorating effects of oroxylin A were antagonized by both muscimol and diazepam (0.25 mg/kg, i.p., respectively), which are GABA(A) receptor agonists. Furthermore, oroxylin A (100 microM) was found to inhibit GABA-induced inward Cl(-) current in a single cortical neuron. These results suggest that oroxylin A may be useful for the treatment of cognitive impairments induced by cholinergic dysfunction via the GABAergic nervous system. 相似文献

特定句法提示对3-4岁儿童错误信念理解的影响 总被引:3,自引:1,他引:2
通过在错误信念任务中,为儿童提供关于错误信念表征的特定句法,考察这种句法理解对儿童的错误信念理解成绩是否有促进作用。124名3-4岁幼儿参加实验,每个年龄组幼儿随机分配到零级提示,一级提示和二级提示等三个句法提示条件组,并完成4个错误信念任务。结果发现,一级提示条件和二级提示条件下的错误信念理解成绩显著高于零级提示条件下的错误信念理解成绩,而一级和二级两种提示条件之间没有显著差异。句法提示对不同的错误信念任务的影响是相同的,对错误信念的预测问题和解释问题的影响模式是一致的。表明对错误信念表征的特定句法提示,有效促进了儿童的错误信念成绩,提示这种句法结构可能有助于儿童的错误信念理解 相似文献

中学生适应取向的心理健康结构初探 总被引:1,自引:0,他引:1
在文献综述的基础上,建构了适应取向的中学生心理健康的理论模型,并对中学生和中学教师进行开放式问卷调查,再参考同类量表,拟定了中学生心理健康量表的题项。经对1,567名中学生进行测试,结果表明:适应取向的中学生心理健康包含生活幸福、乐于学习、人际和谐、考试镇静、情绪稳定等五个维度,本研究所编制的中学生心理健康量表具有良好的信效度。 相似文献
