Emotional labour strategies and job burnout: A meta-analysis of Chinese employees

Emotional labour strategies have a significant impact on job burnout. However, current research results are controversial and unclear. A meta-analysis was conducted to explore the relationship between emotional labour strategies (surface acting and deep acting) and job burnout. A total of 84 empirical studies that included 28,242 participants were selected. The meta-analysis of the relationships between job burnout and surface acting and deep acting included 84 and 75 independent samples respectively. The results show that surface acting had a positive association (r = 0.25) with job burnout, whereas deep acting (r = −0.27) had a negative association with job burnout. Occupational types and measures of emotional labour strategies moderated the relationship between emotional labour strategies and job burnout, but this relationship was not moderated by measures of job burnout.     

睾酮与人类攻击行为

睾酮是一种可以在男性的睾丸间质细胞、女性卵巢和胎盘的皮层细胞中合成并分泌的雄性激素, 它可以调节个体的各种生理、形态和行为过程, 对个体生存和繁殖至关重要。大量研究表明, 睾酮与社会行为的关联存在双向性, 睾酮可以调节社会行为, 社会行为可以反馈并进一步影响睾酮水平。我们将关注点聚焦于睾酮与人类攻击行为之间的关联。早期研究发现, 高睾酮水平个体表现出更高的攻击性; 近期的研究根据挑战假设理论模型和生物社会地位模型得出, 人体内的睾酮水平对竞争性相互作用具有高度反应性。此外, 通过对大量研究的回顾与分析, 我们总结出睾酮水平的变化可以通过增强杏仁核的反应性或减少前额叶皮质-杏仁核功能耦合来影响攻击行为。未来的研究者应考虑其他激素(如皮质醇)和人格特征调节睾酮和人类攻击行为之间关系的潜在作用, 以及相关的生物学机制。     

计算模型在道德认知研究中的应用

道德认知关注道德心理背后的信息加工。近年来, 研究者开始将计算模型应用于道德认知研究, 以探索道德认知如何在大脑中实现。但目前研究者对道德认知进行计算建模的研究处于起步阶段。计算模型(漂移扩散模型、效用模型、强化学习模型和分层高斯过筛器模型)在道德认知行为和生理研究上的运用量化了道德决策、道德判断和道德推理背后的认知过程和神经机制。此外, 这一新进展对理解反社会行为和精神障碍等有所助益。最后, 计算建模有待完善, 未来研究需要关注其潜在的问题。     

农村重点高中学生学校人际关系状况的调查研究

采用《中学生师生关系测验问卷》和《中学生同学关系测验问卷》对随机选取的1120名苏北农村省级重点高中生进行测试。结果发现：绝大多数高中生的师生关系、同学关系是良好的和一般的,师生关系较差的只有6%左右,同学关系较差的却有20%左右;师生关系和同学关系都存在着显著的年级差异和性别差异。     

决策与推理的双系统——启发式系统和分析系统

近来,在决策与推理的研究中,研究者提出了双系统作用模型：基于直觉的启发式系统和基于理性的分析系统。启发式系统加工速度较快,不占用或占用很少的心理资源,容易受背景相似性、刻板印象的影响;分析系统加工速度慢,占用较多的心理资源,遵从逻辑和规则,而且两个系统有不同进化历史和神经基础。该文根据已有的相关研究,综述了双系统在决策与推理中可能的作用机制、相互关系、个体差异,同时指出了目前研究存在的不足     

攀缘激活的计时机制

攀缘激活指神经元在两个先后出现事件的间隔阶段呈现出的一种缓慢爬升式“期待”激活。这种激活的强度在后一事件出现时达最高峰,以致被视为一种可能时距编码机制而成为目前时间生物学研究的一个热点问题。目前攀援激活的计时作用神经机制有三种主要观点：膜电流假说、双稳态单元假说、线性整合假说。未来研究将主要集中于探索攀缘激活的神经元突触机制,非固定间隔时距条件下攀缘激活的计时机制及攀缘激活、运动准备和脉冲累加之间的关系。     

材料呈现方式、维度数量对小学生分类活动影响的眼动研究

使用ASL-504型眼动仪,采用2×2的被试问设计,对46名智力、视力均正常的小学生在两种材料呈现方式下．对维度不同的2套图片材料的分类结果和分类过程中的主要跟动指标加以考察。结果表明：（1）材料呈现方式和维度交互影响着小学生的分类结果;（2）小学生分类结果是否存在显著的材料呈现方式与维度差异．与他们在分类过程中的兴趣区数、注视时间、注视次数、注视频率、注视点持续时间等跟动指标存在着一定的关系。     

线索效度间隔对“采纳最佳”启发式的影响

以Br?觟der的“五线索二择一”任务为研究范式,探讨线索效度间隔对“采纳最佳”启发式的影响。结果发现：当线索效度间隔为0.04时,被试采用“采纳最佳”启发式的次数处于随机水平,随着线索效度间隔的增大,被试采用“采纳最佳”启发式的次数明显高于随机水平;对立线索信息不同,线索效度间隔对“采纳最佳”启发式的影响也不同。     

Performance of the CES-D and its short forms in screening suicidality and hopelessness in the community

A measurement scale should be short and quick to complete if it is to be practically useful. Drawing on data from a community-based survey of 2,178 people in Hong Kong, we compared five short forms (5- to 10-item) and the original version (20-item) of the Center for Epidemiologic Studies-Depression Scale (CES-D; Radloff, 1977) in predicting suicidal attempts and suicidal thoughts. Short forms with as few as nine items performed in ways very similar to the full version; a version with only five items had a detectable difference from the full version. Sensitivity, specificity, and predictive values in differentiating people with and without suicidal thought or attempt change almost linearly with the cut-offs.     

Perceived motivational team climate in relation to task and social cohesion among male college athletes

The purpose of the study was to examine the relationship between perceptions of the motivational team climate and task and social cohesion among male college athletes. Basketball and soccer players (n = 179) completed two response measures, the Perceived Motivational Climate in Sport Questionnaire‐II (Newton, Duda, & Yin) and the Group Environment Questionnaire (GEQ; Carron, Widmeyer, & Brawley) before practice in a team setting near the end of the competitive season. Hierarchical linear modeling analysis revealed that individual perceptions of a task‐involving climate positively predicted, and perceptions of an ego‐involving climate negatively predicted, individual‐attraction‐to‐group task cohesion. Further analysis indicated that perceptions of a task‐involving climate also significantly predicted individual‐attraction‐to‐group social cohesion and group‐integration task cohesion. Perceptions of an ego‐involving climate failed to demonstrate any other predictive value in relation to team cohesion. Discussion underscores the beneficial nature of a task‐involving motivational team climate in regard to the formation and development of task and social cohesion among competitive male college athletes.
