文化常模和目标调节模型:两种幸福感文化观

随着世界经济的发展,人们物资生活水平的提高,如何提高生活质量这一问题引起了越来越多的关注。20世纪60年代后期,主观幸福感(SWB)的研究逐步在全世界范围内形成热潮。近年来,幸福感属性中的文化差异引起了跨文化研究者的极大兴趣。文章通过比较SWB跨文化研究中新近出现的两个理论模型——文化常模模型和目标调节模型,探讨了文化在SWB产生过程中的作用,并在此基础上分析了情绪性幸福感和生活意义之间的关系。

Psychometric Properties of the Bullying Participant Behaviors Questionnaire (BPBQ) among Chinese Middle School Students

The Bullying Participant Behaviors Questionnaire (BPBQ) is an efficient self-report measure for investigating bullying participant role behaviors. The present study evaluated the psychometric properties of the BPBQ in a Chinese middle school sample. A total of 516 middle school students (47.7% girls; age range?=?12–14 years) were recruited from an urban middle school in China. Results revealed that a five-factor model fit the data best. Correlations between the BPBQ subscale scores and the external criterion variables, including empathy and sympathy, moral disengagement, and trait anger, provided evidence of criterion validity. Furthermore, the BPBQ had good alpha reliability and moderate to good test-retest reliability. In conclusion, the BPBQ is a promising assessment tool to measure bullying participant behaviors among Chinese middle school students.

     

中英文Stroop干扰效应的脑机制

以中国大学生为被试,采用事件相关电位对比研究中英文Stroop干扰效应的脑内时程动态变化。结果发现：两种文字材料都存在反应时的Stroop干扰效应,汉字的干扰效应明显强于英文;被试在完成不同文字材料的字词颜色命名任务时所诱发的ERP成分存在差异,具体为中文Stroop干扰效应表现为在350—550ms内,不一致条件比一致条件诱发一个更负的ERP成分（N450）,主要分布于额中部电极。英文Stroop干扰效应表现为不一致条件比一致条件在250—450ms内诱发一个更正的ERP成分（P300）,主要分布于左侧额顶叶;在450—550ms内诱发一个更负的ERP成分（N500）,主要分布于中后部。研究结果表明语言类型会影响Stroop干扰效应的脑内时程变化。

You are what you tweet: Personality expression and perception on Twitter

Microblogging services such as Twitter have become increasingly popular in recent years. However, little is known about how personality is manifested and perceived in microblogs. In this study, we measured the Big Five personality traits of 142 participants and collected their tweets over a 1-month period. Extraversion, agreeableness, openness, and neuroticism were associated with specific linguistic markers, suggesting that personality manifests in microblogs. Meanwhile, eight observers rated the participants’ personality on the basis of their tweets. Results showed that observers relied on specific linguistic cues when making judgments, and could only judge agreeableness and neuroticism accurately. This study provides new empirical evidence of personality expression in naturalistic settings, and points to the potential of utilizing social media for personality research.     

Different brain mechanisms between stereotype activation and application: evidence from an ERP study

Stereotyping involves two processes in which first, social stereotypes are activated (stereotype activation), and then, stereotypes are applied to given targets (stereotype application). Previous behavioral studies have suggested that these two processes are independent of each other and may have different mechanisms. As few psychophysiological studies have given an integrated account of these stages in stereotyping so far, this study utilized a trait categorization task in which event-related potentials (ERPs) were used to explore the brain mechanisms associated with the processes of stereotype activation and its application. The behavioral (reaction time) and electrophysiological data showed that stereotype activation and application were elicited respectively in an affective valence identification subtask and in a semantic content judgment subtask. The electrophysiological results indicated that the categorization processes involved in stereotype activation to quickly identify stereotypic and nonstereotypic information were quite different from those involved in the application. During the process of stereotype activation, a P2 and N2 effect was observed, indicating that stereotype activation might be facilitated by an early attentional bias. Also, a late positive potential (LPP) was elicited, suggesting that social expectancy violation might be involved. During the process of the stereotype application, electrophysiological data showed a P2 and P3 effect, indicating that stereotype application might be related to the rapid social knowledge identification in semantic representation and thus may be associated with an updating of existing stereotypic contents or a motivation to resolve the inconsistent information. This research strongly suggested that different mechanisms are involved in the stereotype activation and application processes.

Category-selective attention modulates unconscious processes in the middle occipital gyrus

Many studies have revealed the top-down modulation (spatial attention, attentional load, etc.) on unconscious processing. However, there is little research about how category-selective attention could modulate the unconscious processing. In the present study, using functional magnetic resonance imaging (fMRI), the results showed that category-selective attention modulated unconscious face/tool processing in the middle occipital gyrus (MOG). Interestingly, MOG effects were of opposed direction for face and tool processes. During unconscious face processing, activation in MOG decreased under the face-selective attention compared with tool-selective attention. This result was in line with the predictive coding theory. During unconscious tool processing, however, activation in MOG increased under the tool-selective attention compared with face-selective attention. The different effects might be ascribed to an interaction between top-down category-selective processes and bottom-up processes in the partial awareness level as proposed by Kouider, De Gardelle, Sackur, and Dupoux (2010). Specifically, we suppose an “excessive activation” hypothesis.
