Compassion at the mirror: Exposure to a mirror increases the efficacy of a self-compassion manipulation in enhancing soothing positive affect and heart rate variability

We tested whether a mirror could enhance the efficacy of a self-compassion manipulation in increasing soothing positive affect and heart rate variability (HRV). Eighty-six participants generated four phrases they would use to soothe and encourage their best friend. Second, they described an episode where they criticized themselves and were assigned to one of three conditions: (a) repeat the four phrases to themselves while looking at the mirror; (b) repeat the four phrases to themselves without the mirror; (c) look at themselves in the mirror without repeating the phrases. Participants in condition (a) reported higher levels of ‘soothing’ positive affect and HRV compared to participants in conditions (b) and (c). The effect of the ‘phrases at the mirror’ manipulation on soothing affect was mediated by increased common humanity. The mirror enhances the efficacy of this self-compassion manipulation in activating the soothing affect system connected with parasympathetic nervous system activity.     

负性情绪抑制对社会决策行为的影响

利用心理生理实验法, 通过将情绪抑制操作引入最后通牒博弈实验范式, 探讨负性情绪抑制的主观情绪体验、生理反应及其对社会决策行为的影响。以40名大学生为被试, 采用MP150型16导生理记录仪记录皮肤电反应和心率。实验为2 (组别：情绪抑制组、自然观看组) × 2 (性别：男、女) × 2 (博弈对手：人、计算机) × 4 (分配方案：￥5：￥5、￥7：￥3、￥8：￥2、￥9：￥1)的混合设计, 其中组别和性别为被试间因素, 博弈对手和分配方案为被试内因素。结果发现：(1)对负性情绪进行抑制没有减少被试相应的主观体验, 情绪抑制使皮肤电反应性增强; (2)负性情绪抑制的主观体验和生理反应不存在性别差异; (3)在面对不公平的分配方案时, 情绪抑制组被试比自然观看组更倾向于拒绝接受。结果表明在最后通牒博弈中,情绪抑制影响回应者的行为反应,使他们更倾向于做出不理智的决策。     

特里尔社会应激测试(TSST)对唾液皮质醇分泌的影响

特里尔社会应激测试(Trier Social Stress Test: TSST)是国外应用广泛的社会心理应激测试手段, 然而还没有研究对其在中国的适用性进行报告。本研究以健康大学生为被试, 分别采用主观应激报告(简明心境量表和5点量表)和客观应激参数(心率和唾液皮质醇)为指标, 探讨TSST在中国的适用情况以及性别因素对个体在TSST应激情境中的影响。结果发现, TSST诱发了中国被试显著的应激反应, 在经历了TSST情境后, 被试主观报告紧张水平增加, 同时心跳加速, 唾液皮质醇水平增加。即使女性被试主观报告紧张与不安的程度显著高于男性, 但是男性和女性在TSST应激情境下的心跳和唾液皮质醇指标没有差异。研究结果提示, TSST在中国被试中具有良好的适用性, 可以利用其开展与社会心理应激相关的研究。男女被试在与成就动机相关的应激源(例如, TSST)中的客观应激参数差异不明显。     

认知评价对主观情绪感受和生理活动的作用

围绕认知评价对情绪的作用, 针对传统认知评价实验方法的缺陷, 本研究改进认知评价的操作方法, 以情绪片段为实验材料, 以事先的评价背景替代与观看同步的评价策略, 以生理指标与情绪自评反映情绪变化, 考察41名大学生的认知评价对负性情绪的影响。结果发现, 持有利于情绪调节评价的个体, 负性情绪感受降低, 皮肤电反应减弱, 但心率无变化。研究表明, 认知评价影响个体的主观情绪体验, 并在一定程度上抑制负性情绪所致的生理唤起的增高。     

Reward Influence on the Heart: Cardiovascular Response as a Function of Incentive Value at Five Levels of Task Demand

This study examined cardiovascular effects of incentive value in men and women confronted with cognitive challenges that were more and less difficult to meet. Participants performed computer memory tasks varying in difficulty from low to high, with instructions that they could earn chances toward a $100 prize or $10 prize by attaining a 90% success rate. Analysis of cardiovascular responses assessed during work revealed an interaction between difficulty and incentive value for heart rate. Participants' heart rate responses were proportional to task difficulty and unaffected by incentive value in all conditions except for the most difficult one. Where difficulty was greatest, $100 participants showed relatively high heart rate responsiveness, whereas $10 participants showed low heart rate responsiveness. This heart rate finding corroborates and extends cardiovascular results from previous experiments, and lends further support to the view that cardiovascular responses will be proportional to incentive value only under some task conditions.     

The role of lay beliefs about group transgressions in acceptance of responsibility for ingroup harm-doing

Denial of responsibility by perpetrator groups is the most common response to group-based transgressions. Refusal to acknowledge responsibility has dire consequences for intergroup relations. In this research we assessed whether shifting lay beliefs about group-based transgressions in general influences acceptance of responsibility for a specific ingroup transgression. In two experimental studies we manipulated lay beliefs about group transgressions as reflecting either a group's stable character (i.e., a global defect construal) or a specific characteristic (i.e., a specific defect construal). Specific defect construals (compared to global defect construals) increased acceptance of ingroup responsibility by increasing group malleability beliefs, but reduced acceptance of ingroup responsibility by reducing the ingroup's perceived moral failure. These effects were moderated by ingroup superiority in Study 1, but not Study 2. We draw implications for our understanding of mechanisms of denial of responsibility, identity threat, and coping with this threat.     

β-受体阻滞剂治疗慢性心力衰竭的哲学发展观

随着科学技术的快速发展和人们认识的不断深入,慢性心力衰竭（CHF）的发病机制处于不断嬗变的过程,CHF的药物治疗概念也发生了根本性的变化。β-受体阻滞剂在CHF的治疗策略中,经历了从禁用到必用的过程,成为了CHF药物治疗的重大突破。大量临床试验表明,β-受体阻滞剂不仅能改善患者预后,而且能明显改善左室的舒张和收缩功能,全面改善患者的血流动力学,提高患者的运动耐量和生活质量,延长生存时间。β-受体阻滞剂在CHF治疗中地位的变化,体现了哲学发展观与疾病的治疗以及药物应用的紧密联系,指导着我们的临床实践,也体现了哲学与自然科学的密切联系。本文将β-受体阻滞剂治疗CHF的新旧观念进行阐述、比较,对其作用机制以及临床用药进行介绍,并对其发展空间进行展望。随着科学的进步,人类有能力从长远的角度控制疾病。     

Action versus state orientation moderates the relation between executive function task performance and resting heart rate variability

Despite a considerable rationale for a relationship between executive functions (EFs) and resting heart rate variability based on the neurovisceral integration model, meta-analyses reveal relatively small effect sizes. This study aims to evaluate this relationship in three EF tasks by taking task characteristics and implicit affect and attention regulation measured by action-state orientation into account. Analyzing 154 participants (M = 23.56 years; SD = 3.14) indicated that the relationship was moderated by action-state orientation. However, the Johnson-Neyman test only found a relationship for state-oriented individuals, which also differed in the direction between demanding and low-demanding tasks. Therefore, this study cannot fully confirm the neurovisceral integration model. Implications for future research are discussed.     

工作记忆刷新训练改善抑郁倾向大学生情绪调节能力的HRV证据

根据流调中心用抑郁量表(CES-D)和贝克抑郁量表(BDI-II-C)的得分情况招募健康被试20例, 抑郁倾向被试40例, 以自愿参加的分组方式将抑郁倾向被试分为工作记忆刷新训练组和对照组, 每组20例。对训练组进行为期20天的工作记忆刷新训练, 对照组不做处理。记录各组被试在前后测的刷新功能以及在情绪调节任务中量表的得分情况, 并收集各组被试在5种实验条件下的心率变异性(HRV)的频域指标值, 结果发现：前测时抑郁倾向个体的HF-HRV显著低于健康个体的平均水平。经过工作记忆训练, 后测的抑郁倾向训练组在情绪调节任务中的HF-HRV水平有显著的提高, 贴近健康对照组的水平, 并与抑郁倾向对照组分离。研究表明, 工作记忆刷新训练能够使抑郁倾向大学生的HRV活动更接近健康被试的HRV活动, 表明抑郁倾向大学生的情绪调节能力得到了改善。
