大脑电刺激在听觉语言加工研究中的应用

大脑电刺激是历史悠久但近年来才广泛应用在人类被试上的实验技术。通过对颅内刺激位点进行电刺激, 并分析引发的暂时性行为功能变化和记录位点的电位活动, 大脑电刺激技术可以揭示认知加工过程中脑区内的功能作用与脑区间的有效连接。通过对听觉语言加工过程相关的丘脑、听觉皮层、高级语言皮层进行电刺激, 现有研究发现了各个脑区的不同功能特点以及不同脑区间的信息传递机制, 为进一步探索听觉语言加工的神经机制提供了新的视角。     

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.

Leader Humor Extends beyond Work: how and when Followers Have Better Family Lives

Although the consequences of leader humor on subordinates have been well documented, the important issues of how and when leader humor affects employees’ attitudes or behaviors beyond the workplace have received limited attention. We integrate the humor literature with spillover-crossover theory to address the gap regarding the implications of leader humor in the nonwork domain. By performing an experiment and two field studies involving employee-spouse dyads, we consistently find 1) a positive association between leader humor and followers’ job satisfaction, 2) a spillover effect of followers’ job satisfaction on subordinates’ work-to-family enrichment (WFE) and a crossover effect of subordinates’ WFE on their spouses’ marital satisfaction, 3) serial mediating effects of followers’ job satisfaction and WFE on the leader humor-spouses’ marital satisfaction link, and 4) a stronger positive indirect effect of leader humor on spouse’ marital satisfaction via followers’ job satisfaction and WFE when followers’ perceived organizational interpersonal harmony is low. We discuss the theoretical implications of these findings and suggest practical implications for developing leader humor to enhance employee well-being.

     

Testing the myth of the encoding–retrieval match

The view that successful memory performance depends importantly on the extent to which there is a match between the encoding and retrieval conditions is commonplace in memory research. However, Nairne (Memory, 10, 389–395, 2002) proposed that this idea about trace–cue compatibility being the driving force behind memory retention is a myth, because one cannot make unequivocal predictions about performance by appealing to the encoding–retrieval match. What matters instead is the relative diagnostic value of the match, and not the absolute match. Three experiments were carried out in which participants memorised word pairs and tried to recall target words when given retrieval cues. The diagnostic value of the cue was varied by manipulating the extent to which the cues subsumed other memorised words and the level of the encoding–retrieval match. The results supported Nairne’s (Memory, 10, 389–395, 2002) assertion that the diagnostic value of retrieval cues is a better predictor of memory performance than the absolute encoding–retrieval match.     

A cross-lagged model of self-esteem and life satisfaction: Gender differences among Chinese university students

Past research has shown a close relationship between self-esteem (SE) and life satisfaction (LS). Using cross-lagged structural equation modeling, the current longitudinal study examined the directionality of the relationship among a sample of Chinese university students (214 males and 134 females). In the model, SE and LS at Time 1 were used to predict SE and LS at Time 2, with socioeconomic status (SES) as the independent variable of both constructs. Results showed that SE consistently predicted subsequent LS among both genders, whereas no significant effects of LS on subsequent SE were found. Furthermore, SES had significant effects on LS among both genders. Its influence on SE, however, was significant among females only. Implications and limitations are discussed.     

The interaction between surface color and color knowledge: behavioral and electrophysiological evidence

In this study, we used event-related potentials (ERPs) to evaluate the contribution of surface color and color knowledge information in object identification. We constructed two color-object verification tasks - a surface and a knowledge verification task - using high color diagnostic objects; both typical and atypical color versions of the same object were presented. Continuous electroencephalogram was recorded from 26 subjects. A cluster randomization procedure was used to explore the differences between typical and atypical color objects in each task. In the color knowledge task, we found two significant clusters that were consistent with the N350 and late positive complex (LPC) effects. Atypical color objects elicited more negative ERPs compared to typical color objects. The color effect found in the N350 time window suggests that surface color is an important cue that facilitates the selection of a stored object representation from long-term memory. Moreover, the observed LPC effect suggests that surface color activates associated semantic knowledge about the object, including color knowledge representations. We did not find any significant differences between typical and atypical color objects in the surface color verification task, which indicates that there is little contribution of color knowledge to resolve the surface color verification. Our main results suggest that surface color is an important visual cue that triggers color knowledge, thereby facilitating object identification.     

Beyond negotiated outcomes: The hidden costs of anger expression in dyadic negotiation

This paper focuses on the hidden costs of expressing anger in negotiations. Two experimental studies show that an opponent’s expression of anger can elicit both concessionary and retaliatory responses by focal negotiators. In the first study, equal-power negotiators exhibited overt concessionary behaviors when their opponents expressed anger, but also sabotaged their opponents covertly. Feelings of mistreatment mediated the relationship between opponents’ anger expression and focal negotiators’ covert retaliation. In the second study, low-power negotiators made larger concessions when high-power opponents expressed anger, but they retaliated covertly against high-power negotiators. High-power negotiators were overtly demanding (and not concessionary) regardless of whether or not the opponent expressed anger, but also retaliated covertly against low-power opponents who expressed anger. The two studies suggest that the value-claiming advantages of expressed anger need to be weighed against the costs of eliciting (covert) retaliation. We discuss implications of the findings and provide recommendations for future research.     

不同心理一致感初中生对压力的态度激活研究

该研究采用不同加工任务的间接测量方法,探讨不同心理一致感水平初中生对压力的外显认知倾向和内隐态度激活程度。结果表明:1)初中生较为稳定的积极认识和反应倾向在他们关于压力的外显认知加工中起了更为显著的作用;2)不同加工方式的虚惊率差异表明存在着初中生对压力情境的内隐态度,且这种无意识认知较为消极。
