摘要 为探究大学生微信成瘾的原因及其心理机制,采用自尊量表、网络人际信任量表、状态焦虑量表和微信成瘾量表对931名来自三所高校的大学生进行调查。结果表明:(1)自尊与焦虑、微信成瘾显著负相关;焦虑与网络人际信任显著负相关;网络人际信任、焦虑与微信成瘾显著正相关。(2)自尊对微信成瘾有显著的直接预测作用,而且能够通过焦虑、以及焦虑和网络人际信任的链式中介作用间接对微信成瘾产生影响。研究结果对减少大学生微信成瘾具有一定的借鉴意义。  相似文献

基于进化领域的生命史理论,采用两种实验启动的途径探讨性别比、童年经济状况和女性长短期择偶偏好间的关系。结果表明:女性在长期择偶中更为重视男性的“好爸爸”和“好资源”,在短期择偶中更为重视男性的“好基因”;性别比在女性长期择偶的“好爸爸”偏好上具有显著主效应,在“女多男少”情境下女性对“好爸爸”的偏好水平会较“男多女少”时明显提高;性别比和童年经济状况在女性长期择偶“好爸爸”偏好上的交互效应显著:童年贫穷女性在“女多”情境下会明显提高对长期择偶“好爸爸”的偏好水平,童年富裕女性在性别失衡情境下对长期“好爸爸”的偏好保持相对稳定。  相似文献

以往研究普遍从建言行为的建设性意图特征出发, 探讨其关键前因、产生机制和情境因素, 但却较少关注建言行为的工具性目的。基于资源保存理论, 本研究构建了有调节的中介模型以探讨工作压力影响员工建设型建言和防御型建言的作用机制和边界条件。通过对某建筑企业386名员工进行两阶段调查, 结果表明:工作压力与防御型建言存在正向相关关系, 与建设型建言存在负向相关关系, 自我损耗在其中起中介作用; 另外, 领导开明性正向调节自我损耗和建设型建言的负向相关关系, 并正向调节工作压力通过自我损耗影响建设型建言的间接效应。  相似文献

以往研究认为满足基本生活需求后, 消费者购买与幸福感不显著相关。近期研究发现, 购买是否能够提升幸福感, 取决于如何购买, 例如购买体验产品比物质产品更有利于提升幸福感, 但存在边界条件。文章从个人层面的享乐适应、预期利益、非对称后悔视角及社会层面的社会利益视角对这一结论进行解释, 并从个人因素、情境因素及幸福感的类型三个层面识别了物质购买在提升幸福感上表现更优异的边界条件, 同时对该领域未来可能的创新研究方向进行展望。  相似文献

Vision unfolds as an intricate pattern of information processing over time. Studying vision and visual cognition therefore requires precise manipulations of the timing of visual stimulus presentation. Although standard computer display technologies offer great accuracy and precision of visual presentation, their temporal resolution is limited. This limitation stems from the fact that the presentation of rendered stimuli has to wait until the next refresh of the computer screen. We present a novel method for presenting visual stimuli with ultrahigh temporal resolution (<1 ms) on newly available gaming monitors. The method capitalizes on the G-Sync technology, which allows for presenting stimuli as soon as they have been rendered by the computer’s graphics card, without having to wait for the next screen refresh. We provide software implementations in the three programming languages C++, Python (using PsychoPy2), and Matlab (using Psychtoolbox3). For all implementations, we confirmed the ultrahigh temporal resolution of visual presentation with external measurements by using a photodiode. Moreover, a psychophysical experiment revealed that the ultrahigh temporal resolution impacts on human visual performance. Specifically, observers’ object recognition performance improved over fine-grained increases of object presentation duration in a theoretically predicted way. Taken together, the present study shows that the G-Sync-based presentation method enables researchers to investigate visual processes whose data patterns were concealed by the low temporal resolution of previous technologies. Therefore, this new presentation method may be a valuable tool for experimental psychologists and neuroscientists studying vision and its temporal characteristics.  相似文献

The religious mobility of immigrants has rarely received a systematic investigation that separates the two mutually exclusive mechanisms: the structural shift that occurs due to an overall environment favorable to certain religions, and the exchange effect that occurs when people voluntarily flow between any pair of two religions. Chinese overseas students constitute the largest foreign student body in the US whose religious mobility pattern remains unexplored and may differ significantly from other types of immigrants in earlier generations, especially regarding the assumed growth of Christianity and changes within other religions and non-religions. Applying quasi-symmetry log-linear model to the pre- and post-immigration religious identifications in a new sample of Chinese oversea students collected from the Midwest in 2016 (n = 916), this study shows that (1) Abrahamic religions including Christianity and Islam have the biggest structural advantage; (2) Eastern religions including Buddhism, Chinese folk religions, and generic polytheism have suffered from structural disadvantages; (3) religious nones (i.e. atheists and agnostics) have remained relatively stable with little structural variation; (4) net of the structural effects, there is a higher level of mutual exchange of members between Buddhism and polytheism, between atheism and agnostic, and between Christianity and atheism.  相似文献

Two experiments were conducted to examine the effect of the mental retardation (MR) label on impression formation among retarded and nonretarded children and adolescents. The first experiment, conducted with nonretarded children in a mainstreamed school, indicated that they have pessimistic expectations of retarded children with regard to cognitive and ability-related behaviorsand, to a lesser extent, social behaviors (i.e., getting married). However, their reactions were not as pessimistic nor as “patronizing” as were those demonstrated by college students in previous research. In the second experiment, mentally retarded adolescents indicated that they also have negative behavioral expectations of retarded children, however, their self expectations were negative only for social behaviors. The results suggest that, among retarded persons, the expectations associated with the MR label are negative for social behavior, but apparently less pessimistic for cognitive and ability related tasks.  相似文献

This prospective study examined the relation between 308 adolescents' images of typical dinkers and nondrinkers and their subsequent alcohol consumption. The results indicate that both images are associated with changes in consumption between ages 16 and 18 but that they operate in different ways. Contrary to previous assumptions, drinker images do not represent goal states for adolescents in that they are more negative than their self-images and nondrinker images and are not correlated with their ideal selves. In contrast, nondrinker images do appear to represent goal states for adolescents who abstain from drinking. Implications for intervention are discussed.  相似文献
