虚无主义、语言和创造性：尼采与德里达的界限

尼采和德里达对虚无主义危机做出了不同的回应.这是因为作为主体解读活动及其结果,虚无主义危机本身表现出两可性:一方面,形而上学的真理意志已经演变为一种桎梏,带来了虚无主义的"虚无化"或人类创造性和历史的终结;另一方面,危机也构成主体走出形而上学的条件.德里达更注重对前者进行否定性批判,揭开了形而上学追求超验真理所带的虚无性,或追问本源所掩盖的"本源"缺失.尼采开启了这种批判,不过他更渴望逆转这种潮流,进行更具建设性的重构,而不只是把主体抛在丧失了"意义"的空场上.其目的是脱离消极的虚无主义,复兴各种冲动在主体创造性中的作用.     

Psychological Flexibility at Work and Employees' Proactive Work Behaviour: Cross‐Level Moderating Role of Leader Need for Structure

How to promote employees to be proactive behaviourally is a significant issue in the literature because it would benefit organisations in several ways. Drawing on the acceptance and commitment model, we proposed a new antecedent, psychological flexibility that might contribute to employees' proactive work behaviour. Furthermore, we investigated how the contextual role of supervisor need for structure exhibits a cross‐level moderating effect on the relationship between employee psychological flexibility at work and proactive work behaviour based on interactionism. Data from 241 full‐time employees and their corresponding 45 managers indicated that employee psychological flexibility was positively associated with proactive work behaviour. More importantly, the supervisor need for structure played a moderating role, suggesting that employees would demonstrate greater proactive work behaviour especially when the supervisors have a high need for structure. Implications for psychological flexibility, proactivity, and person‐situation interactional research are discussed.     

急性应激损害对威胁刺激的注意解除

急性应激会增强个体对威胁刺激的注意偏向, 但急性应激是增强了对威胁刺激的注意定向还是损害了对威胁刺激的注意解除还不清楚。本研究采用社会评估冷压任务和点探测任务, 结合事件相关电位技术, 考察急性应激对威胁刺激注意偏向影响的认知机制。在进行社会评估冷压任务后, 应激组个体的状态焦虑和皮质醇浓度显著升高。在注意偏向中, 应激组对威胁刺激的注意解除比控制组更慢, 应激组和控制组在对威胁刺激的注意定向上无显著差异。ERP结果上, 威胁刺激诱发应激组比控制组产生了更负的SPCN, 在N2pc上没有显著差异。应激组和控制组皮质醇增量的差异和N2pc、SPCN的组间差异均有显著正相关。这些结果说明, 急性应激增强对威胁刺激的注意偏向是因为其损害个体对威胁刺激的注意解除, 这可能是因为急性应激损害了与注意解除相关的额-顶网络的功能所致。     

直觉和分析在不同信息获取与呈现方式下对多特征目标判断质量的影响

采用多特征目标判断任务,考察了不同信息获取方式与信息呈现方式条件下,直觉和分析思维模式对判断质量的影响。结果发现：（1）在多特征目标判断任务中,直觉思维比分析思维更有效;（2）直觉型决策者运用直觉思维的判断质量比感觉型决策者更高;（3）归类组块的信息呈现方式能够有效提升决策者运用直觉思维的判断质量;（4）思维模式、信息获取方式与信息呈现方式对多特征目标的判断质量存在三阶交互作用,归类组块的信息呈现方式使直觉型决策者运用直觉思维的判断质量最高,而运用分析思维的判断质量低于感觉型决策者;归类组块排列信息时,直觉型决策者运用分析思维的判断质量低于信息随机排列时的水平。

The Culture-Embedded Social Problem of Elder Mistreatment: A Review of International Literature on Asian Elders

Elder mistreatment is now recognized as a worldwide social problem occurring in all racial and ethnic groups. The research on elder mistreatment started in the late 1970s and expanded its focus to ethnic elderly groups including Asian elders in the mid-1980s. Many researchers have explored the issues of elder mistreatment in conjunction with Asian elders’ culture and immigration backgrounds. This article reviews the state of the literature on elder mistreatment among Asians living in Asia or abroad to identify future directions of research, prevention, intervention, and policy. This research indicates that prevention, education, and intervention must take into account the cultural backgrounds of Asian elders and their family members. There is clearly a need for greater research into appropriate elder mistreatment prevention and intervention with Asian elders and their family members.     

认知控制的层级性：来自任务切换的脑电证据*

认知控制的主要研究范式之一是任务切换。以往研究发现切换代价受到认知控制层级性的调节, 但鲜有研究探索这一调节过程的动态神经机制。本研究通过嵌套的线索-任务切换范式考察不同层级任务切换代价的差异及其神经机制。在实验中, 要求被试完成高低两种层级任务, 低层级任务要求被试判断数字大小(或奇偶); 高层级任务则须先加工数字的某一语义特征(如当前数字是否是偶数), 然后进行大小判断。行为结果表明, 高层级任务切换代价显著大于低层级任务切换代价。线索锁时的脑电结果表明, 层级效应最早出现于P2成分, 切换效应(切换与重复之差)在CNV成分上受到任务层级的调控, 反映了在任务目标重构阶段给予高层级任务更多的选择性注意以及更高的主动性控制。目标锁时的脑电结果表明, 在N2及慢波(SP)成分上, 高层级任务切换与重复的波幅差异相比低层级任务显著更大, 反映了在抑制旧任务集与重构新反应集的过程中增强的反应性控制。这些结果为任务设置重构论和认知控制的层级性提供了新的证据。     

二孩家庭父母偏爱的特点及其与青少年抑郁的关系

对1655名来自二孩家庭的青少年进行调查,以考察二孩家庭中父母偏爱的特点及其与青少年抑郁的关系。结果发现：（1）父母偏爱水平较低,且父亲偏爱和母亲偏爱不存在显著差异。（2）父母偏爱存在性别和出生次序差异,男孩报告父母更偏爱自己,女孩报告父母更偏爱同胞;头胎子女报告父亲更偏爱自己,母亲更偏爱同胞,二胎子女则相反。（3）父母偏爱对青少年抑郁有显著影响,且为U型曲线关系,即当父母偏爱同胞或中高程度偏爱自己时,青少年抑郁水平均较高;当父母较低程度偏爱自己时,青少年抑郁水平最低。说明二孩家庭中不存在严重的父母偏爱,但父母偏爱会对青少年发展产生消极影响。     

Young Women’s Experience of Sexuality: A Battle of Pleasure and Sexual Purity in the Context of Malaysian Society

Little is known regarding the ways in which Malaysian women’s sexuality is constructed, and how their personal experiences, culture, religion and society influence their feeling, attitude and sexual behaviours. This study explored the sexual experiences of young adult women in the developing context of the country. A qualitative phenomenological approach was adopted. Purposive sampling was employed, and a total of 20 participants were recruited, comprised of the major ethnic groups in Malaysia. Four main themes emerged through the phenomenological analysis of the data, including: conditional pleasure; social honour and women’s purity; risk and responsibility; and transcendence of love and emotion. The findings of this study revealed that sexuality was experienced under the control of religion and society with the concern of conserving a woman’s purity and social honour; and imposing risks and responsibility on women. Despite the awareness of women’s right to experience sexual pleasure, it was commonly perceived that sexual activities beyond the social norms will result in social shaming and guilt. The authors recommend appropriate sexuality education regarding sexual assertiveness and communication, safe-sex practices, and improving sexual decision-making skills.
