内外向者幽默加工进程差异:ERP研究

本研究采用事件相关电位技术(ERP),探究幽默的加工进程及内外向者在加工进程中的差异。研究以笑话为实验材料,要求被试先浏览背景信息和妙句结尾,然后评估先后呈现的文字材料的关系。行为结果:内向者的反应时显著短于外向者。ERP结果:(1)幽默加工过程包括不一致探测阶段、不一致消解阶段和情绪加工阶段。(2)不一致无关的N400波幅显著大于一致不可笑;不一致无关的P600波幅显著小于不一致可笑和一致不可笑;800ms之后不一致可笑引发了比一致不可笑和不一致无关更大的正波幅。(3)内外向者在幽默加工进程上的差异主要体现在幽默加工阶段的早期。与内向者相比,外向者在幽默不一致探测阶段所用的认知资源较少,加工的自动化程度较高。     

Collective and Individual Self-Esteem Mediate the Effect of Self-Construals on Subjective Well-Being of Undergraduate Students in China

Human psychology and behavior are influenced by culture. Self-construals reflect the individualism-collectivism dimension at the level of individual personality. The current study aimed to explore how self-construals affect subjective well-being (SWB) in China, which has a collectivist culture. Chinese undergraduates (N?=?442) participated in this study. They responded to the self-construal scale, Rosenberg self-esteem scale, collective self-esteem scale and measures of SWB. The results suggested that the type of self-construal significantly predicted SWB. Moreover, an individual’s self-esteem completely mediated the impact of independent self-construal on SWB, whereas interdependent self-construal influenced SWB directly, as well as indirectly though collective self-esteem. In addition, collective self-esteem promoted individual self-esteem, which in turn further stimulated SWB. These findings extend prior reports and shed light on how individual differences in self-construal affect SWB.     

Validation of the Chinese Version of the Body Image Acceptance and Action Questionnaire and the Mediating Role of Body Image Flexibility in the Relationship Between Body Dissatisfaction and Psychological Distress

The psychometric properties of the Chinese version of the Body Image Acceptance and Action Questionnaire (C-BI-AAQ) and its short form (C-BI-AAQ-5) were examined with a sample of Chinese undergraduates (n = 1,068, 52.6% female). The factor structure, measurement reliability, measurement invariance across gender, and latent gender mean difference of the two scales were explored. Confirmatory factor analysis was used to examine the factor structure of the C-BI-AAQ and the C-BI-AAQ-5. The original one-factor structure was replicated for both the C-BI-AAQ and the C-BI-AAQ-5. Both the C-BI-AAQ and C-BI-AAQ-5 showed good internal consistency, test-retest reliability, and convergent and discriminant validity (e.g., relationship patterns in the expected directions with theoretically similar psychological flexibility, and with theoretically dissimilar body dissatisfaction, and psychological distress). The C-BI-AAQ-5 was shown to be equivalent to the C-BI-AAQ. Furthermore, strict measurement invariance across gender was confirmed for both the C-BI-AAQ and C-BI-AAQ-5, and latent mean difference tests showed that men had higher levels of body image flexibility than women. Thus, both the C-BI-AAQ and C-BI-AAQ-5 appear to be psychometrically sound instruments for use in the Chinese young adult population. In addition, body image flexibility measured by both the C-BI-AAQ and the C-BI-AAQ-5 fully mediated the relationship between body dissatisfaction and psychological distress.     

Pinyin and English Invented Spelling in Chinese-Speaking Students Who Speak English as a Second Language

This study examined pinyin (the official phonetic system that transcribes the lexical tones and pronunciation of Chinese characters) invented spelling and English invented spelling in 72 Mandarin-speaking 6th graders who learned English as their second language. The pinyin invented spelling task measured segmental-level awareness including syllable and phoneme awareness, and suprasegmental-level awareness including lexical tones and tone sandhi in Chinese Mandarin. The English invented spelling task manipulated segmental-level awareness including syllable awareness and phoneme awareness, and suprasegmental-level awareness including word stress. This pinyin task outperformed a traditional phonological awareness task that only measured segmental-level awareness and may have optimal utility to measure unique phonological and linguistic features in Chinese reading. The pinyin invented spelling uniquely explained variance in Chinese conventional spelling and word reading in both languages. The English invented spelling uniquely explained variance in conventional spelling and word reading in both languages. Our findings appear to support the role of phonological activation in Chinese reading. Our experimental linguistic manipulations altered the phonological awareness item difficulties.

儿童歧视知觉模型述评

Brown和Bigler提出了儿童歧视知觉模型,分析了歧视知觉的三个影响因素:认知因素、情景因素和个体差异因素,每个因素都包含了多个影响儿童歧视知觉的子因素。该模型展示了这些因素影响儿童歧视知觉的机制。完善该模型需要探讨其与信息加工理论、发展群际理论、主观群体动力学模型的兼容性。歧视知觉的类型需要进一步细化,因此在综合主观群体动力学模型和发展模型的基础上提出了歧视知觉的分类方案。未来研究还要进一步探讨情绪、文化以及年龄因素对儿童歧视知觉的影响,并探讨该模型对歧视干预的意义。     

Cognitive control and attentional functions

Cognitive control is essential to flexible, goal-directed behavior under uncertainty, yet its underlying mechanisms are not clearly understood. Because attentional functions are known to allocate mental resources and prioritize the information to be processed, we propose that the attentional functions of alerting, orienting, and executive control and the interactions among them contribute to cognitive control in the service of uncertainty reduction. To test this hypothesis, we examined the relationship between cognitive control and attentional functions. We used the Majority Function Task (MFT) to manipulate uncertainty in order to evoke cognitive control along with the Revised Attention Network Test (ANT-R) to measure the efficiency and the interactions of attentional functions. A backwards, stepwise regression model revealed that performance on the MFT could be significantly predicted by attentional functions and their interactions as measured by the ANT-R. These results provide preliminary support for our theory that the attentional functions are involved in the implementation of cognitive control as required to reduce uncertainty, though further investigation is needed.     

Health Is Associated With Antiparasite Behavior and Fear of Disease-Relevant Animals in Humans

Evolutionary arms races between humans and parasites resulted in a set of behavioral adaptations that serve as parasite-avoidance mechanisms. We investigated associations among reported health of the respondent, antiparasite behavior, and sensitivity to disgust and fear of disease-relevant and irrelevant animals. Ninety-seven participants (15–19 years old) rated their fear and disgust at 25 colorful pictures of disease-relevant and disease-irrelevant invertebrates. Consistent with previous work, we found that participants reported greater fear and disgust of disease-relevant invertebrates relative to disease-irrelevant invertebrates. Better perceived health correlated with lower fear of disease-relevant invertebrates. Sensitivity to disgust correlated with reported antiparasite behaviors. Contrary to expectations, we found a positive correlation between antiparasite behavior and reported health, which suggests that antiparasite behavior influences perceived health (but not vice versa), and we found that males perform more antiparasite behaviors than females. These results support the idea that disgust and fear of disease-relevant objects are adaptive emotions that prevent contact with contagious objects, especially in individuals with low perceived health.
