身体姿势启动的内隐权力感对公平决策的影响

已有研究表明, 扩张身体姿势可启动个体的权力感。基于具身认知的视角, 实验1考察身体姿势对免惩罚游戏的提议者进行金钱分配时的影响, 实验2和实验3分别考察最后通牒游戏、免惩罚游戏的回应者在蜷缩和扩张姿势下对各种分配类型方案的拒绝率。结果表明, 与蜷缩姿势相比, 扩张姿势使个体更倾向于在免惩罚游戏提议者角色时做出更多的利己不公平分配, 同时使个体更倾向于拒绝最后通牒游戏和免惩罚游戏中的不公平分配。本研究证明了扩张姿势启动的权力感可影响个体的公平决策。     

Exploring correlations between positive psychological resources and symptoms of psychological distress among hematological cancer patients: a cross-sectional study

Hematological cancer patients experience high levels of psychological distress during diagnoses and intensive treatments. The aim of the present study is to explore the effects of positive psychological resources on depressive and anxiety symptoms in hematological cancer patients. This survey was conducted in a hospital during the period from July 2013 to April 2014. A total of 300 inpatients were recruited and finally 227 of them completed the questionnaires. Questionnaires included demographic and clinical variables, the Center for Epidemiologic Studies Depression Scale, the Self-Rating Anxiety Scale, the Life Orientation Scale-Revised, the General Perceived Self-Efficacy Scale, and the Resilience Scale-14. Results showed that the prevalence of depressive and anxiety symptoms was 66.1 and 45.8%, respectively. Both optimism (β = ?.479, p < .001) and resilience (β = ?.174, p < .05) were negatively associated with depressive symptoms, and optimism (β = ?.393, p < .001) was negatively associated with anxiety symptoms. However, resilience (β = ?.133, p > .05) was not significantly associated with anxiety symptoms, and self-efficacy was not significantly associated with depressive (β = ?.032, p > .05) or anxiety symptoms (β = ?.055, p > .05). The results suggest that hematological cancer patients who possess high levels of positive psychological resources may have fewer symptoms of psychological distress. The findings indicate that enhancing positive psychological resources can be considered in developing intervention strategies for decreasing depressive and anxiety symptoms.     

Effects of varying numbers of Likert scale points on factor structure of the Rosenberg Self‐Esteem Scale

Likert‐type rating scales are among the most widely used tools in psychological research. Different numbers of response categories would likely affect response style, data distribution, reliability, and construct validity. There is a lack of research in factor structure invariance under Likert scales with different numbers of categories. The purpose of this study is to examine the effects of varying numbers of Likert points (4–11) on scale properties such as factor structure, external validity, and latent means based on the Rosenberg Self‐Esteem Scale (M. Rosenberg, 1989 ). The sample consists of 1,807 students from secondary schools in Macau. Confirmatory factor analysis shows that the correlated two‐factor model is the most appropriate one; longitudinal invariance analysis reveals that measurement invariance across Likert scales was satisfied at the scalar level. In addition, latent mean scores on the two factors as well as observed means on the subscales are comparable across Likert scales. Moreover, the measurement model across Likert scales exhibit similar external validity. Although psychometric properties are mostly similar among a different number of points, the 4‐point Likert scale is not recommended for its higher skewness and lower loadings; the 11‐point Likert scale from 0 to 10 is slightly preferred for its higher loadings and composite reliability.

Using game theory to examine incentives in influenza vaccination behavior

The social good often depends on the altruistic behavior of specific individuals. For example, epidemiological studies of influenza indicate that elderly individuals, who face the highest mortality risk, are best protected by vaccination of young individuals, who contribute most to disease transmission. To examine the conditions under which young people would get vaccinated to protect elderly people, we conducted a game-theory experiment that mirrored real-world influenza transmission, with "young" players contributing more than "elderly" players to herd immunity. Participants could spend points to get vaccinated and reduce the risk of influenza. When players were paid according to individual point totals, more elderly than young players got vaccinated, a finding consistent with the Nash equilibrium predicting self-interested behavior. When players were paid according to group point totals, however, more young than elderly players got vaccinated-a finding consistent with the utilitarian equilibrium predicting group-optimal behavior-which resulted in higher point totals than when players were paid for their individual totals. Thus, payout structure affected whether individuals got vaccinated for self-interest or group benefit.     

孕12周～14周血小板计数及平均血小板体积对子痫前期的预测作用

幼儿语言发展中的形状偏好现象及其认知机制

形状偏好是指儿童语言发展过程中倾向于认为相同形状的物体拥有相同名称的现象。已有研究采用词汇拓展、分类和归纳推理等任务发现, 2~3岁甚至更早的幼儿就已经表现出形状偏好, 且表现受刺激物的属性、创造者的意图和功能及因果/比较关系等因素影响。然而, 形状偏好现象存在着联结观和概念观两种不同的解释。未来的研究应该采用认知神经科学的方法, 并结合发展中的其它问题, 从特殊被试和跨文化的角度来探讨这一现象的神经机制。     

Teaching Engineering Ethics using BLOCKS Game

The aim of this study was to investigate the use of a newly developed design game called BLOCKS to stimulate awareness of ethical responsibilities amongst engineering students. The design game was played by seventeen teams of chemical engineering students, with each team having to arrange pieces of colored paper to produce two letters each. Before the end of the game, additional constraints were introduced to the teams such that they faced similar ambiguity in the technical facts that the engineers involved in the Challenger disaster had faced prior to the space shuttle launch. At this stage, the teams had to decide whether to continue with their original design or to develop alternative solutions. After the teams had made their decisions, a video of the Challenger explosion was shown followed by a post-game discussion. The students’ opinion on five Statements on ethics was tracked via a Five-Item Likert survey which was administered three times, before and after the ethical scenario was introduced, and after the video and post-game discussion. The results from this study indicated that the combination of the game and the real-life incident from the video had generally strengthened the students’ opinions of the Statements.
