睡眠不足对人际交互的影响及其认知神经机制

睡眠不足会对人的认知、情感和人际交互产生诸多影响。这种影响在社会情绪层面表现为个体情绪共情和认知共情的减少,易激惹性与愤怒情绪的增加;在社会行为层面则表现为亲社会行为的减少和攻击行为的增加。在睡眠不足状态下,情绪系统和认知系统功能连接的减弱可能是这些变化的潜在机制。未来应结合生态效度较高的睡眠操作手段,系统考察睡眠不足如何导致各种高级社会情绪的改变,以及这些社会情绪的变化如何导致社会行为的变化。

Resting Heart Rate,Vagal Tone,and Reactive and Proactive Aggression in Chinese Children

Abundant research conducted in Western contexts has shown that biological risk factors such as low resting heart rate (HR) might be related to childhood aggression. However, it was unclear (1) how resting HR, as well as other markers of cardiac functions such as resting vagal tone, may be related to subtypes of aggression such as reactive and proactive aggression, and (2) whether the HR-aggression relation can be replicated in non-Western contexts. Therefore, this study examined the concurrent and prospective relations between resting HR, vagal tone, and Chinese children’s reactive and proactive aggression. Participants were 183 children (M age?=?7.64 years, 91 girls) recruited from an elementary school in Zhenjiang, PRC. Children’s resting HR and vagal tone were assessed in the second grade (T1). Teachers rated children’s reactive and proactive aggression in the second (T1) and fourth grade (T2). Results showed that lower resting HR at T1 was associated with higher reactive and proactive aggression at T1 and T2, and higher vagal tone was associated with lower HR, which in turn was related to higher reactive and proactive aggression at T1 and T2. Lower vagal tone was directly related to higher reactive but not proactive aggression at T1 and T2, whereas lower HR was related to higher reactive aggression at T2 for children with low or moderate vagal tone but was not for children with high vagal tone. These psychophysiological findings from a non-Western context add additional support for both similarities and differences between reactive and proactive aggression in childhood.     

Contextualising Risk and Building Resilience: Returnees Versus Local Entrepreneurs in China

Risk is a pivotal concept in entrepreneurship research, as entrepreneurs constantly face uncertainty, ambiguity, setbacks, and stressful situations. Attitudes toward risk vary contingent upon individual risk preferences and cultural influences. Building resilience is critical for entrepreneurs to overcome obstacles, deal with risk, and grow their ventures. By juxtaposing effectuation theory and resilience literature, we compare the perceptions of risk held by Chinese returnees and local entrepreneurs and their coping strategies in building resilience. Our research reveals two types of coping approaches, namely effectual coping and causal coping. This study contributes to the comparative international entrepreneurship literature by contextualising the notion of risk held by entrepreneurs influenced by Eastern and Western cultures. Our study further contributes to the nascent literature on resilience in organisations by specifying the entrepreneurial occupational context and exploring the influence of cultures on resilience, and by identifying distinctive resilience-building coping strategies based upon cultural influences and interpretations of risk. Furthermore, we suggest that resilience can constitute one micro-foundation of effectuation theory in the context of entrepreneurship dealing with risk.     

Does power corrupt? The moderating effect of status

Findings on the effect of power on corruption are mixed. To make sense of these mixed results, three studies were conducted to examine the moderating role of status on this effect. In Study 1, corrupt intent was measured using a corruption scenario that contained manipulations of power and status. In Study 2, corrupt behaviour was measured in a corruption game that contained manipulations of power and status. Study 3 was conducted in real organisational settings, and aimed to expand the external validity of Studies 1 and 2. The results of all three studies consistently indicated that the effect of power was moderated by status. Specifically, power increased corruption when status was low, whereas this effect disappeared when status was high. The implications of reducing the facilitating effect of power on corruption by considering status from the perspective of social hierarchy are discussed.     

Mechanism underlying the self-enhancement effect of voice attractiveness evaluation: self-positivity bias and familiarity effect

The aim of the present study was to determine whether the self-enhancement effect of voice attractiveness evaluation is due to general self-positivity bias and/or the familiarity effect. The participants were asked to rate the attractiveness of their own voice, a friend's voice and strangers' voices. In addition, a self-reference valence (SR-valence) task was adopted in the experiment. Significant self-enhancement effects in voice attractiveness ratings were demonstrated, regardless of whether the participants recognized their self-voice or not. However, the friend-enhancement effect was found in only those participants who successfully recognized their friend's voice. Moreover, a significant correlation was found between self-positivity bias in the SR-valence task and the self-enhancement effect (but not the friend-enhancement effect). Our findings suggest that both the familiarity effect and self-positivity bias account for the vocal self-enhancement effect, and the influence of self-positivity bias could be implicit. The present study thus provides empirical evidence to clarify the potential explanations for the self-enhancement of voice attractiveness assessment.     

《神仙传》中天人感应故事的原型研究

本文通过对《神仙传》中彭祖、沈羲、李少君等几则天人感应故事及其特征的分析,提出天人感应包括天人同构与彼此感应两方面。天人感应并非葛洪首创,《神仙传》中天人感应的思想渊源可以沿《列仙传》追溯至董仲舒的宗天神学。进一步的研究告诉我们,董仲舒思想是对春秋思想中天人感应思想的发挥,而处于巫史传统中的春秋思想又是神话-仪式思维的直接结果。结合西方神话-原型批评理论,笔者认为天人同构及其感应关系源自巫史传统,它是世界各民族的原始先民所共同具有的一种神话-仪式思维。作为原型思维,天人感应在历代文学文本中以不同面貌呈现,它是这些互文文本中的可交际单位,在不同历史语境中不断地被置换、变形和重新书写。     

当代新兴人类增强技术的“激进主义”与“保守主义”:理论主张及论争启示

以物理增强、认知增强、道德增强、情感增强为主的当代新兴人类增强技术(H ET)对人的深度“干预”使“人”陷入“深度技术化”状态从而引发了激烈论争,形成了“激进主义”与“保守主义”两大对立阵营。双方论争焦点主要集中在:关于什么是“人”的形而上学问题;认知进化与退化、道德工具化与趋同化、情感真实性与同质化等人的社会属性问题;自主性与自主权、公平与公正、健康与安全等增强技术使用问题。双方论争角度呈现出多样性特征,且各自在自身的理论框架下具有一定程度的合理性。论争双方的对立,有的是利益分歧,有的是价值或文化冲突,达成共识的可能性较低,理想的状态应该是两者之间如何取得均衡,保持“必要的张力”,共同推动新兴人类增强技术的健康良性发展。
