社会认知复杂性是描述个体社会认知结构特点的个体差异变量,作为社会认知领域的研究热点,当前却鲜有研究关注它与同伴交往的关系。本研究选取初一至高二234名中学生考察了社会认知复杂性与同伴交往之间的关系,并辅以人际交往能力、学业成就通过结构方程模型进一步探讨了二者之间关联的路径。结果表明:(1)青少年社会认知复杂性与同伴接受、同伴拒绝、人际交往能力、学业成就之间存在显著相关。社会认知复杂性高的学生获得了较多的同伴接纳、较少的同伴拒绝,并具有较高的人际交往能力和学业成就。(2)青少年社会认知复杂性以人际交往能力和学业成就为中介变量间接影响同伴的受欢迎程度。 相似文献

The aim of this study was to examine the prevalence of Internet addiction in a nationally representative sample of college students and to identify any associated psychosocial risk factors. The present study was constructed using a cross-sectional design with 3,616 participants. Participants were surveyed during the middle of the spring and fall semesters and recruited from colleges around Taiwan using stratified and cluster random sampling methods. Associations between Internet addiction and psychosocial risk factors were examined using stepwise logistic regression analysis. The prevalence of Internet addiction was found to be 15.3 percent (95 percent confidence interval, 14.1 percent to 16.5 percent). More depressive symptoms, higher positive outcome expectancy of Internet use, higher Internet usage time, lower refusal self-efficacy of Internet use, higher impulsivity, lower satisfaction with academic performance, being male, and insecure attachment style were positively correlated with Internet addiction. The prevalence of Internet addiction among college students in Taiwan was high, and the variables mentioned were independently predictive in the logistic regression analysis. This study can be used as a reference for policy making regarding the design of Internet addiction prevention programs and can also aid in the development of strategies designed to help Internet-addicted college students. 相似文献

This article reports a meta-analysis of energy expenditure (EE) of playing active video games (AVGs). In particular, heart rate (HR), oxygen consumption (VO2), and EE were assessed and three moderators for the effects of AVGs--types of AVG, player age, and player weight status--were analyzed. The results show that playing AVGs significantly increased HR, VO2, and EE from resting. The effect sizes of playing AVGs on HR, VO2, and EE were similar to traditional physical activities. AVG type and player age were significant moderators for the effects of AVGs. The finding suggests that AVGs are effective technologies that may facilitate light- to moderate-intensity physical activity promotion. 相似文献

Social network sites enable users to express themselves, establish ties, and develop and maintain social relationships. Recently, many companies have begun using social media identity (e.g., Facebook fan pages) to enhance brand attractiveness, and social network sites have evolved into social utility networks, thereby creating a number of promising business opportunities. To this end, the operators of fan pages need to be aware of the factors motivating users to continue their patronization of such pages. This study set out to identify these motivating factors from the point of view of social capital. This study employed structural equation modeling to investigate a research model based on a survey of 327 fan pages users. This study discovered that ties related to social interaction (structural dimension), shared values (cognitive dimension), and trust (relational dimension) play important roles in users' continued intention to use Facebook fan pages. Finally, this study discusses the implications of these findings and offers directions for future research. 相似文献

In a field study involving university students from Canada and Japan, we tested hypotheses from the theory of uncertainty
orientation (Sorrentino and Roney in The uncertain mind: Individual differences in facing the unknown. Psychology Press, Philadelphia 2000). Consistent with previous research, those possessing an uncertainty orientation that matched their culture’s predominant
style of uncertainty regulation perceived a better student-classroom fit than those who did not match their culture’s predominant
style of uncertainty regulation. More importantly, we predicted and found that actual course grades varied as a function of
the culture’s style of uncertainty regulation in interaction with the participant’s uncertainty orientation and achievement-related
motives. Implications of these findings and applied relevance are discussed. 相似文献

This study constructed the image quality models for a small mobile display under different ambient illumination levels using Group Method and Data Handling (GMDH) and described the relationship between perceived image quality and physical measurements. 33 college students took part in this experiment and were asked to evaluate the image quality under 1500 lux (typical indoor office illumination) and 7000 lux (simulated outdoor environment) in Stage One and Stage Two, respectively. In each stage, the participants had to evaluate 21 images. 17 sets of the data as a training set were used to build the model and four sets of the data as a testing set were used to verify the model. The results indicated that the effects of luminance, contrast, correlated color temperature (CCT), and resolution were significant on perceived image quality under 1500 lux. However, color temperature was not a significant physical characteristic, and an interaction between luminance and contrast was found below 7000 lux. From the results of the experiment, it is considered that the outdoor environment (7000 lux) is not suitable for using mobile displays. Finally, once a valid image quality model is built, the subjective image quality can be established when the measurements of significant physical characteristics are provided. The results of subjective ratings can also be provided for mobile display manufacturers to improve the product quality so that their products can meet customers' requirements. 相似文献

Some evidence suggests that acceptance-based approaches such as Acceptance and Commitment Therapy (ACT) may be well-suited to geriatric generalized anxiety disorder (GAD). The primary goal of this project was to determine whether ACT was feasible for this population. Seven older primary-care patients with GAD received 12 individual sessions of ACT; another 9 were treated with cognitive-behavioral therapy. No patients dropped out of ACT, and worry and depression improved. Findings suggest that ACT may warrant a large-scale investigation with anxious older adults. 相似文献
