自我旋转面孔识别的ERPs研究

本研究采用事件相关电位技术考察平面旋转角度对自我面孔识别影响的时间进程。实验采用面孔异同匹配范式(same-different judgment), 首先呈现一张正立的自我或他人内特征的探测面孔, 然后再呈现一张旋转至某个角度(0°、90°、180°)的自我或他人的目标面孔, 要求被试判断两张面孔是否属于同一个人, 并记录其判断的反应时和ERP成分。实验发现, 在N170 (180~240 ms)和N2 (240~300 ms)成分上, 旋转至90°、180°的面孔刺激比正立条件下的面孔刺激分别在枕颞叶和额区诱发了更大的平均波幅。在LPP (400~500 ms)成分上, 对于自我面孔, 正立条件、旋转至90°、旋转至180°所诱发的波幅差异显著。而对于他人面孔, 3个角度所诱发的波幅无显著差异。结果表明, 面孔识别早期阶段是自动化的结构编码, 旋转角度增加了面孔结构编码的难度; 在面孔识别晚期阶段, 大脑对面孔的特异性信息进行精细加工, 自我面孔会占用个体有限认知资源进行下一步精细的心理旋转加工, 因此平面旋转角度会调节晚期个体对自我面孔的加工过程, 并且其影响时间约为100 ms。     

健康的贫富差距及其内在机制

健康的贫富差距是指不同社会经济地位的群体在各种健康指标上的系统差异。在过去30余年间, 国外研究揭示了社会经济地位与各种健康指标的负向关系, 并从环境特征和个人特征两个层面对健康的贫富差距做出了解释。以实证证据为基础, 研究者提出了社会文化自我模型、储备能力模型和生物−心理−社会整合模型等理论模型, 尝试从综合的视角理解健康的贫富差距。未来研究应该从多学科跨领域的视角, 使用多样化的研究方法和统计技术深化对健康的贫富差距内在机制的理解, 充分考虑社会文化背景的影响和个体差异的存在, 为促进我国的健康公平实践工作提供切实有效的理论指导。     

Not myself and the connected self: cases of youth depression and recovery in Malaysia

This study aims to explore the subjective experience of depressed young people in Malaysia. Twelve participants aged 20–24, who were diagnosed as suffering from depression but who had recovered, were interviewed. An adapted grounded theory approach guided our data collection and data analysis process. Two themes emerged which revealed the importance of the connectedness of individuals within their social environment. Coping with cultural norms and with rejection were found to be the most stressful precursors to depression. Depression is described as an alienating and involuntary experience. The recovery process requires a pivotal moment which enables reconnection with others. Implication of study will be discussed against the backdrop of the Malaysian context.     

Source Credibility in Consumer-Generated Advertising in Youtube: The Moderating Role of Personality

This research investigates the effects of the big five consumer personality traits on perceptions of source credibility related to consumer-generated advertising (CGA). An online experiment with 175 participants was conducted with viewing of a YouTube video in which source credibility (as firm-generated or consumer-generated) was manipulated. Findings show participants viewed CGA as more credible than firm-generated advertising. CGA positively influenced attitudes toward the ad and brand for consumers with low openness, and positively influenced opinion giving for consumers with high extraversion and low neuroticism. Also, a significant main effect of neuroticism was found. Theoretical and practical implications, and suggestions for future research are discussed.     

Empathy‐Related Responding in Chinese Toddlers: Factorial Structure and Cognitive Contributors

The critical role of the second year of life in the development of empathy is well accepted by psychologists. However, the developmental trends of the different components of empathy and the potential factors underlying these components during this critical period remain unclear. Eighty‐four Chinese toddlers in the second year of life participated in the present study. Empathy‐related responses were observed during three simulated procedures performed by each child's primary caregiver, the experimenter and a baby doll. An exploratory factor analysis was used to identify the different components of empathy. The shared representation of the self and others was measured using the Tasks for the Observation of Self‐Concept, self/other awareness was measured with a series of mirror tests and inhibitory control was measured using the Cylinder Inhibitory Control Task. The results showed that the empathy of Chinese toddlers contains three factors: sympathy, personal distress and orientation. Potential cognitive factors contribute to the different components of empathy through both independent and joint effects. © 2016 The Authors Infant and Child Development Published by John Wiley & Sons, Ltd.     

Partner effects of Mexican cultural values: the couple and parenting relationships

In this investigation, the authors explored the impact of individuals' cultural values on their partners' relationship adjustment and perceptions of their parenting relationship. The authors examined Mexican cultural values of simpatía (i.e., harmonious interpersonal relationships) and respeto (i.e., respect for authority figures) using a sample of 50 Mexican-origin couples in southern Arizona. Congruent with their hypotheses, results supported the proposition that fathers' simpatía is positively associated with both relationship adjustment and the parenting relationship as reported by mothers, whereas fathers' respeto is negatively associated with both relationship adjustment and the parenting relationship as reported by mothers. However, the authors found little evidence of a contribution of mothers' cultural values to fathers' perceptions of either relationship adjustment or the parenting relationship. They interpret these findings to suggest that mothers' relationship adjustment and parenting relationship are more sensitive to and dependent on fathers' degree of traditional cultural values among Mexican-origin families.     

Culture, emotion regulation, and adjustment

This article reports differences across 23 countries on 2 processes of emotion regulation--reappraisal and suppression. Cultural dimensions were correlated with country means on both and the relationship between them. Cultures that emphasized the maintenance of social order--that is, those that were long-term oriented and valued embeddedness and hierarchy--tended to have higher scores on suppression, and reappraisal and suppression tended to be positively correlated. In contrast, cultures that minimized the maintenance of social order and valued individual Affective Autonomy and Egalitarianism tended to have lower scores on Suppression, and Reappraisal and Suppression tended to be negatively correlated. Moreover, country-level emotion regulation was significantly correlated with country-level indices of both positive and negative adjustment.     

Substance and artifact in the higher-order factors of the Big Five

J. M. Digman (1997) proposed that the Big Five personality traits showed a higher-order structure with 2 factors he labeled alpha and beta. These factors have been alternatively interpreted as heritable components of personality or as artifacts of evaluative bias. Using structural equation modeling, the authors reanalyzed data from a cross-national twin study and from American cross-observer studies and analyzed new multimethod data from a German twin study. In all analyses, artifact models outperformed substance models by root-mean-square error of approximation criteria, but models combining both artifact and substance were slightly better. These findings suggest that the search for the biological basis of personality traits may be more profitably focused on the 5 factors themselves and their specific facets, especially in monomethod studies.     

Turnover of highly educated R&D professionals: The role of pre‐entry cognitive style,work values and career orientation

Retention of key R&D experts has been recognized as a critical managerial challenge for many technology‐based companies. In this study, we propose that turnover of highly educated professional workers is meaningfully related to individual characteristics such as cognitive style, work values and career orientation. We tested the hypotheses using data collected from a sample of 132 R&D professionals with PhD degrees in engineering or natural science in a Korean electronics firm. The time‐dependent risk of turnover was estimated by survival analysis using a proportional hazards regression model. The results showed that over the 7‐year period after their organizational entry, R&D professionals with high levels of intrinsic values and cosmopolitan orientation were more likely to leave the organization than were their counterparts with low levels of intrinsic values and cosmopolitan orientation. The hazard function showed that the positive effect of intrinsic work values on turnover was particularly salient in the third and fourth year of R&D professionals' organizational tenure. We found that the positive effect of cosmopolitan orientation on turnover increased over time, introducing a greater risk of turnover with increasing tenure. The present findings have practical implications for the retention of highly educated R&D professionals in a corporate setting.
