社会距离与合作指数对不同年龄青少年合作行为影响的差异

本研究采用重复囚徒困境实验范式,考察了社会距离和合作指数对不同年龄青少年（初中生、高中生和大学生,且每个年龄段的被试数为40名）在博弈决策中的合作行为的影响。结果发现：（1）随着年龄的增加,青少年合作行为的总体趋势表现为下降;（2）社会距离对大学生的合作行为的正向作用显著,而中学生的合作行为却不受其影响;（3）个体合作率会受到合作指数的促进作用,但这种促进作用在大学生中表现的更为显著。即随年龄增长,个体会更少的采取合作行为,并且个体是否采取合作在更大程度上基于当前博弈中的收支情况和与博弈对象之间的社会距离。     

Body weight and weight perception among African and Caribbean university students: Correlation with depression symptoms

The aim of the study was to investigate the association between body weight, weight perception, and depressive symptoms in African and Caribbean university students. In a cross-sectional survey the total sample included 4 964 undergraduate university students (mean age 21.8, SD = 3.4, age range = 18-30 years) from five African and three Caribbean countries. Data on the students’ actual and perceived body weight, as well as depression symptoms, were collected. In logistic regression, perceived rather than measured overweight predicted depressive symptoms in male students with normal weight. For female students, perceived overweight predicted depression symptoms regardless of actual body weight. Male students who overestimated their body weight were at greater risk of depressive symptoms. Body weight self-perceptions appear to influence experience of mood disorder among African and Caribbean country students.     

风险条件下的跨期选择

跨期选择是指对发生在未来不同时间点上的结果做出权衡的决策过程。由于大部分跨期选择的情景都处于某种风险之中, 把风险变量纳入跨期选择的研究中则至为关键。针对以往研究在研究范围、理论构建、现实意义等诸方面的不足, 本研究拟采用实验室实验与纸笔测验相结合的方法, 深入揭示高、中、低三种概率水平下风险对跨期选择的影响特征, 探索其发生的机制、各类经典效应的大小。在此基础上, 根据全国不同地区的大样本调查结果, 了解各地区风险条件下跨期选择的差异及其与本地宏观经济指标(如, 消费者物价指数)的关联, 进而探讨研究的现实意义。本研究期望对风险条件下的跨期选择做出系统、全面的科学探索, 并为国家相关部门制定政策提供有价值的参考。     

Spirituality and Subjective Well-Being: Evidences for a New Domain in the Personal Well-Being Index

Subjective well-being explores the evaluations, both positive and negative, of how people experience their lives. Research in the field inquires how people perceive their well-being in different settings, including different cultures, regions and cities. A large number of different measures have been designed to capture subjective well-being. One of the most used SWB measure is the Personal Well-being Index (PWI), an evaluation of life developed by Cummins et al [(2003). Social Indicators Research, 64, 159–190] which proposes that satisfaction with life consists of seven different life-domains. Theoretical considerations of the contribution of spirituality and religiosity to life satisfaction, from a eudaimonic (from the Greek, it consists of the word "eu" (good or well-being) and the word “daemon” (spirit)) point of view, led to test the contribution of this new domain in the prediction of the Personal Well-being Index (PWI) in Bogotá, Colombia. Empirical results confirm the construct validity and reliability of the scale. The contribution of the new domain—satisfaction with spirituality and religiosity—to PWI was found significant. Based on these results the paper explores conceptually the role of spirituality contributing to satisfaction with life. The finding stresses the importance of interpreting satisfaction with life as a whole from the Aristotelian concept of eudaimonia. New questions for research in this important area are proposed     

Pylyshyn的索引理论：视觉表征方式的新解释

视觉索引理论是解释人类表征外部世界的一种新理论。首先回顾了索引理论的产生背景,在此基础上阐述索引理论的基本假设以及在不同范式下如多客体追踪、线条错觉运动、前概念选择和感数与计数分离研究所提供的证据。接着,简介其在特殊教育、人机交互和语言学领域的应用。最后,针对新近研究引发对索引理论基本假设的争论如前注意加工是否涉及注意资源、索引阶段对特征信息和时空信息加工的分离等,提出相关研究建议。     

Examining body dissatisfaction in young men within a biopsychosocial framework

This study examined biopsychosocial factors related to body dissatisfaction in young men within multivariate and moderator contexts. A female sample was included as a gender comparison. Male (n = 111) and female (n = 236) undergraduates filled out self-report questionnaires assessing body mass index (BMI), media influence, a history of weight-related teasing, and socially prescribed perfectionism, along with various indices of body dissatisfaction. Perceived pressure from the media was consistently related to body dissatisfaction in men whereas multiple biopsychosocial variables accounted for body dissatisfaction in women. Socially prescribed perfectionism and a history of weight teasing each moderated the relationship between BMI and male body dissatisfaction, identifying men low in body dissatisfaction. Findings indicate that applying a biopsychosocial framework to the study of body dissatisfaction in men is useful and suggest the need for including other factors, such as male peers and sports involvement, in understanding contributors to male body image.     

疼痛表达与中国人表达的躯体化

西方研究者认为中国人习惯用躯体化方式表达心理不适,不能区分身体疼痛和心理痛苦。通过回顾中文文本,认为在传统中国的语境中,身心互应的哲学观念使个体能够以一种隐性但自明的方式来表达自身情感。但在社会变迁的环境中,原有的社会关联多数都已崩解,个体开始使用躯体化以及疼痛作为索引,从而提供自我的某种参照。     

Perceptions of female body weight and shape among indigenous and urban Europeans

Two important cues to female physical attractiveness are body mass index (BMI) and body shape as measured by the waist-to-hip ratio (WHR). This study examined the relative contribution of both cues in three culturally distinct populations. A total of 119 Finnish, Sámi and British male observers rated a set of un-edited photographs of women with known BMI and WHR. The results showed that there were significant differences in preferences for physical attractiveness, with the indigenous Sámi preferring figures with larger BMIs and more tolerant of heavyweight figures than either Finnish participants in Helsinki or Britons in London, who were indistinguishable in their preferences for slim figures. The findings are discussed in terms of evolutionary psychological explanations of mate selection, and sociocultural theories which emphasizes the learning of preferences for body sizes in social and cultural contexts.     

Understanding the relationship between obesity and positive and negative affect: the role of psychosocial mechanisms

We examined the relationship between body mass index (BMI) and positive and negative affect, and evaluated whether this relationship is mediated (or suppressed) by physical health, intrusiveness of weight on physical functioning, and distressing interpersonal interactions. Analyses were based on a national sample of more than 3,000 adults ages 25 to 74. Class II (BMI 35–39.9) and Class III (BMI ≥ 40) obesity were associated with more frequent negative affect and less frequent positive affect, even after demographic and socioeconomic status characteristics were controlled. After the purported pathway variables were controlled, however, obese I persons reported significantly more frequent positive affect, while overweight, obese I, and obese II persons reported significantly less frequent negative affect, compared to normal weight persons. These patterns did not differ significantly by race or gender. Our findings suggest that excessive body weight is not necessarily distressing, yet the physical and interpersonal strains associated with obesity may impair one's mood. We discuss the implications for policy and practice.
