互联网内容偏好与大学生人格特质关系的研究 总被引:4,自引:1,他引:4
本研究对2034名在校大学生的上网情况和人格特质进行测试,探讨大学生网络内容偏好程度与接触频率的关系以及不同人格特质的大学生在互联网内容的偏好上是否有显著性差异。结果表明:(1)接触频率最高的是聊天内容,最低的是网上购物,男生显著高于女生的是游戏类内容,女生显著高于男生的是聊天类内容。(2)不同人格特质的大学生在内容偏好上存在显著差异。 相似文献

采用经典的A:B:C:D范式,设计两类难度不同的图片任务,依据关系-表征复杂性模型从等级复杂性和水平复杂性角度分析任务难度.在此基础上,选取5~9岁115名儿童探讨两类任务上类比推理的特点和发展趋势.表明:(1)儿童类比推理呈现多样化特点,主要有:充分意义上掌握了类比推理、部分完成了类比推理、位置关系类比推理、不能类比推理和不确定情况类比推理,其中部分完成了类比推理是复杂任务上所特有的.(2)简单、复杂两类任务上,随着年龄增长,5-9岁儿童充分意义上掌握类比推理的人次比例不断上升,不能类比推理的人次比例不断下降.此外,复杂任务上,随年龄增长,部分完成类比任务的人次比例降低.结果表明,在简单任务上,前运算阶段儿童已具备了类比推理能力;但在复杂任务上,儿童到了具体运算阶段才具备类比推理能力. 相似文献

传统依恋理论认为个体依恋心理和行为模式具有相对稳定性, 但无论在信息加工还是个体发展过程中, 个体依恋模式均表现出二重性, 即既具有相对稳定性, 又具有情境敏感性。个体在情境中所表现出的依恋模式是个体相对稳定的特质性依恋和情境特征相互作用的结果。依恋启动研究中特质性依恋特征与依恋启动效应之间的交互作用模式为理解依恋二重特征及其关系提供了窗口。依恋系统激活的两阶段模型为整合和解释这些相互作用模式提供了框架。未来研究应优化依恋二重特征关系研究中启动效应的操作检验, 考虑依恋焦虑和回避维度的交互作用, 关注高焦虑群体内的依恋差异, 以理析依恋二重特征之间的相互作用方式, 同时关注依恋策略影响依恋启动效应的时间进程, 探究依恋二重特征相互作用的机制。 相似文献

Findings on the effect of power on corruption are mixed. To make sense of these mixed results, three studies were conducted to examine the moderating role of status on this effect. In Study 1, corrupt intent was measured using a corruption scenario that contained manipulations of power and status. In Study 2, corrupt behaviour was measured in a corruption game that contained manipulations of power and status. Study 3 was conducted in real organisational settings, and aimed to expand the external validity of Studies 1 and 2. The results of all three studies consistently indicated that the effect of power was moderated by status. Specifically, power increased corruption when status was low, whereas this effect disappeared when status was high. The implications of reducing the facilitating effect of power on corruption by considering status from the perspective of social hierarchy are discussed. 相似文献

皮锡瑞以“借事明义”概括《春秋》大旨,是一项错误而又有待辨析的学术主张。承认“事”的次要性、工具性和可阙性,不意味必须接受“事”的可伪性。皮氏的举证不能证明孔子和《公羊》作者同样允许“事”的假托,论证欠缺说服力。此外,“借事明义”的观点不见得符合经传的内容,掩盖了《公》《穀》二传也有强调史实的一面,因此不宜把它视作指导经传解读的有效原则。 相似文献

Limited research has been conducted on dispositional mindfulness, posttraumatic stress disorder (PTSD) symptoms and academic burnout in Chinese adolescents following a tornado. The present study investigated the ways in which dispositional mindfulness is related to PTSD symptoms and academic burnout in Chinese adolescents following a tornado by considering the role of regulatory emotional self-efficacy. A total of 431 Chinese adolescents (mean age: 14.75 years) who had experienced a severe tornado 9 months prior to this study were recruited for this study. The results indicated that our model fit the data well [χ2/df = 2.774, CFI = 0.952, TLI = 0.934, RMSEA (90% CI) = 0.064 (0.051–0.077)], and revealed that regulatory emotional self-efficacy partially mediates the relationships between dispositional mindfulness and PTSD symptoms and academic burnout, respectively. The clinical implications and limitations of our research, and recommendations for future research, are discussed in this paper. 相似文献

Presentation of two kinds of materials in working memory (visual and acoustic), with the requirement to attend to one or both modalities, poses an interesting case for working memory development because competing predictions can be formulated. In two experiments, we assessed such predictions with children 7–13 years old and adults. With development, the ability to hold more information in the focus of attention could lead to an increase in the size of the trade‐off between modalities; if attention can hold A items during unimodal‐attention trials, then on average attention should hold A/2 of those same items during bimodal‐attention trials. If A increases with age, so would the dual‐task cost, A/2. The results clearly ruled out that possibility. It was the modality‐ or code‐specific components of working memory that improved with age and not the central component. We discuss various mechanisms that could have produced these results, including alternative attention‐based mechanisms. The findings point to a rich field for continued research. 相似文献

Using facial muscular movements to understand young children's emotion regulation and concurrent neural activation 下载免费PDF全文

Individual differences in young children's frustration responses set the stage for myriad developmental outcomes and represent an area of intense empirical interest. Emotion regulation is hypothesized to comprise the interplay of complex behaviors, such as facial expressions, and activation of concurrent underlying neural systems. At present, however, the literature has mostly examined children's observed emotion regulation behaviors and assumed underlying brain activation through separate investigations, resulting in theoretical gaps in our understanding of how children regulate emotion in vivo. Our goal was to elucidate links between young children's emotion regulation‐related neural activation, facial muscular movements, and parent‐rated temperamental emotion regulation. Sixty‐five children (age 3–7) completed a frustration‐inducing computer task while lateral prefrontal cortex (LPFC) activation and concurrent facial expressions were recorded. Negative facial expressions with eye constriction were inversely associated with both parent‐rated temperamental emotion regulation and concurrent LPFC activation. Moreover, we found evidence that positive expressions with eye constriction during frustration may be associated with stronger LPFC activation. Results suggest a correspondence between facial expressions and LPFC activation that may explicate how children regulate emotion in real time. 相似文献
