自我信息的反应抑制优势：来自神经振荡的证据

为探明个体对自我信息的反应抑制神经机制,记录了被试在完成面孔识别的停止信号任务时的脑电信号。神经振荡结果显示,反应任务中,加工自我面孔引发了更大的同步化δ节律和去同步化β节律;停止任务中,自我面孔引发了更大的去同步化β节律,特别在大脑前额区和中线上。表明,自我信息的反应抑制优势发生在抑制控制阶段,在于增强的β节律的去同步化促进了运动准备,提高了后续的动作抑制的速度。

Does snobbish service generate better sales? The case of luxury goods

The objective of this study is to explore whether a “bad” service encounter triggers a consumer's impulse purchase in a luxury goods store in an Asian emerging market. A 2 (service encounter: favorable vs. snobbish) × 2 (shopping companion: alone vs. with a close friend) between‐group factorial design was employed with 160 female consumers in an Asian emerging market to examine the antecedents of both the urge to save social identity and the impulse purchase of luxury goods. The results show that consumers in an Asian emerging market can be triggered to make an impulse purchase of a luxury good, not because they received excellent service in the store but because they encountered snobbish service, especially when shopping with a close friend. Research implications and limitations are also discussed.     

Extraversion modulates functional connectivity hubs of resting‐state brain networks

Personality dimension extraversion describes individual differences in social behaviour and socio‐emotional functioning. The intrinsic functional connectivity patterns of the brain are reportedly associated with extraversion. However, whether or not extraversion is associated with functional hubs warrants clarification. Functional hubs are involved in the rapid integration of neural processing, and their dysfunction contributes to the development of neuropsychiatric disorders. In this study, we employed the functional connectivity density (FCD) method for the first time to distinguish the energy‐efficient hubs associated with extraversion. The resting‐state functional magnetic resonance imaging data of 71 healthy subjects were used in the analysis. Short‐range FCD was positively correlated with extraversion in the left cuneus, revealing a link between the local functional activity of this region and extraversion in risk‐taking. Long‐range FCD was negatively correlated with extraversion in the right superior frontal gyrus and the inferior frontal gyrus. Seed‐based resting‐state functional connectivity (RSFC) analyses revealed that a decreased long‐range FCD in individuals with high extraversion scores showed a low long‐range functional connectivity pattern between the medial and dorsolateral prefrontal cortex, middle temporal gyrus, and anterior cingulate cortex. This result suggests that decreased RSFC patterns are responsible for self‐esteem, self‐evaluation, and inhibitory behaviour system that account for the modulation and shaping of extraversion. Overall, our results emphasize specific brain hubs, and reveal long‐range functional connections in relation to extraversion, thereby providing a neurobiological basis of extraversion.     

An exploration of courage in Chinese individuals

Definitional studies of courage have been performed by Western psychologists, but little research has examined Chinese folk courage. Two studies examined conceptions of courage in Chinese culture. In Study 1, the definitions, forms, inner traits, and reactions of courage were described by 307 individuals in China. A content analysis revealed that courage was divided into two forms: individually oriented and socially oriented; and the virtue was composed of persistence, responsibility, and breakthrough. Study 2 conducted in-depth interviews with 27 Chinese participants to explore the nature of courage further. The results suggested similar components; anger, self-confidence, support network, and social atmosphere were most likely to inspire courage; and trying something difficult was the most frequently experienced courageous event. Collectively, persistence and breakthrough were common components of both the current studies and the existing Western literature on courage, while responsibility may be more uniquely Chinese. Implications for prospective training programs are discussed.     

Resistance to Cultural Intervention: Formation of Inhibitory Collective and children’s Self-Defensive Regulation in a Chinese School

A sequel to the previous article “Roots of Excellence: The Releasing Effect of Individual Potentials through Educational Cultural Intervention in a Chinese School” (in press), the present study is on the unexpected reversal phenomena in the process of cultural intervention. The goal of the intervention is to construct the dynamics of Jiti (well-organized collective in Chinese) through creative activities to promote students’ development. In the intervention, the releasing effect (Wu et al. 2016) emerged as well, but the teacher’s concern about worsening discipline and academic performance evoked and reinforced his habitual notions and practices of education, turning the joint activities into a way of strengthening discipline. The energy that had been discharging at the beginning of the intervention was inhibited, so that many more problematic behaviors took shape. The whole class formed an inhibitory atmosphere, within which pupils formed self-defensive regulation strategies. By comparing with the productive collective in which intervention was effective and analyzing this unexpected reversal process, we can not only see pupils’ self-construction status in the inhibitory culture but illuminate the formation of the teacher’s resistance to educational and cultural transformation as well. Resistance is originated from teachers not being able to interpret pupils’ inner developmental needs but instead anxious about the ongoing problems.     

A quick eye to anger: An investigation of a differential effect of facial features in detecting angry and happy expressions

Detection of angry and happy faces is generally found to be easier and faster than that of faces expressing emotions other than anger or happiness. This can be explained by the threatening account and the feature account. Few empirical studies have explored the interaction between these two accounts which are seemingly, but not necessarily, mutually exclusive. The present studies hypothesised that prominent facial features are important in facilitating the detection process of both angry and happy expressions; yet the detection of happy faces was more facilitated by the prominent features than angry faces. Results confirmed the hypotheses and indicated that participants reacted faster to the emotional expressions with prominent features (in Study 1) and the detection of happy faces was more facilitated by the prominent feature than angry faces (in Study 2). The findings are compatible with evolutionary speculation which suggests that the angry expression is an alarming signal of potential threats to survival. Compared to the angry faces, the happy faces need more salient physical features to obtain a similar level of processing efficiency.     

Burnout among Finnish and Chinese university students

In this study the levels of experienced burnout of Finnish and Chinese university students are compared using School Burnout Inventory (SBI). This study is motivated by earlier studies, which suggest that the level of student burnout is different in the culturally distinct Finnish and Chinese university systems, but which are based on different research instruments for the two groups. The sample studied consisted of 3,035 Finnish students and 2,309 Chinese students. Because of the cross‐cultural nature of this study the level of structural equivalence of SBI between the cultural groups was examined and the effect of different response styles on the results was taken into account. Both standard and robust statistical methods were used for the analyses. The results showed that SBI with two extracted components is suitable for cross‐cultural analysis between Finnish and Chinese university students. Virtually no difference was found in experienced overall burnout between the Finnish and Chinese students, which means that both university systems contain factors causing similar levels of student burnout. This study also verified that controlling for the response styles is important in cross‐cultural studies as it was found to have a distinct effect on the results obtained from mean‐level comparisons.     

运动技能水平与躯体感觉输入对运动表象的影响

运动表象质量与运动技能水平有关,运动表象质量随着运动技能水平的提高而上升。器械使用可使人脑产生可塑性改变,使用者会将器械纳入身体图式。然而,两者影响运动表象的神经心理机制还不清楚。本研究采用功能性磁共振成像探析篮球运动员与新手在不同持球条件下表象投篮时脑功能活动的差异。结果表明运动员表象质量较好,镜像神经系统激活高于新手;持球条件下运动员表象质量显著高于不持球条件下,镜像神经系统激活程度显著低于不持球条件下。研究说明持器械可以显著提高运动员的表象质量,器械使用带来镜像神经系统的可塑性变化。
