善恶评价的性质和善恶评价的真理性问题是伦理学研究的难点问题。现代西方伦理学界对此问题也多有探讨。对现代西方善恶评价理论的主要观点的介绍,有助于我们深化善恶评价问题的研究。     

Cortisol response and psychological distress predict susceptibility to false memories for a trauma film

For eyewitness testimony to be considered reliable, it is important to ensure memory remains accurate following the event. As many testimonies involve traumatic, as opposed to neutral, events, it is important to consider the role of distress in susceptibility to false memories. The aim of this study was to investigate whether cortisol response following a stressor would be associated with susceptibility to false memories. Psychological distress responses were also investigated, specifically, dissociation, intrusions, and avoidance. Participants were allocated to one of three conditions: those who viewed a neutral film (N?=?35), those who viewed a real trauma film (N?=?35), and a trauma “reappraisal” group where participants were told the film was not real (N?=?35). All received misinformation about the film in the form of a narrative. Participants provided saliva samples (to assess cortisol) and completed distress and memory questionnaires. Cortisol response was a significant predictor of the misinformation effect. Dissociation and avoidance were related to confabulations. In conclusion, following a stressor an individual may differ with regard to their psychological response to the event, and also whether they experience a cortisol increase. This may affect whether they are more distressed later on, and also whether they remember the event accurately.     

Self-relevance enhances susceptibility to false memory

Eyewitness testimony serves as important evidence in the legal system. Eyewitnesses of a crime can be either the victims themselves—for whom the experience is highly self-referential—or can be bystanders who witness and thus encode the crime in relation to others. There is a gap in past research investigating whether processing information in relation to oneself versus others would later impact people's suggestibility to misleading information. In two experiments (Ns = 68 and 122) with Dutch and Chinese samples, we assessed whether self-reference of a crime event (i.e., victim vs. bystander) affected their susceptibility to false memory creation. Using a misinformation procedure, we photoshopped half of the participants' photographs into a crime slideshow so that they saw themselves as victims of a nonviolent crime, while others watched the slideshow as mock bystander witnesses. In both experiments, participants displayed a self-enhanced suggestibility effect: Participants who viewed themselves as victims created more false memories after receiving misinformation than those who witnessed the same crime as bystanders. These findings suggest that self-reference might constitute a hitherto new risk factor in the formation of false memories when evaluating eyewitness memory reports.     

激活水平和呈现方式对错误记忆的影响

随机抽取80名大学生参与实验,采用DRM(Deese-Roediger-Mcdermott)范式,探讨了激活水平和呈现方式对错误记忆的影响。结果发现:(1)在随机呈现条件下,关键诱饵的错误再认率显著低于分组呈现条件,但学过项目的正确再认率在两种条件下无差异。(2)在高激活水平条件下,学过项目的正确再认率明显低于低激活水平条件,但关键诱饵的错误再认率在两种激活条件下的差异不够明显。这表明,呈现方式对关键诱饵的错误再认率有显著影响,而激活水平的影响则不显著。由此可知,人们的记忆可以在没有任何外界信息干扰的情况下因内在联想过程而自发地发生改变。     

听障儿童错误信念理解与谎言理解的关系：情绪理解的调节作用

本研究主要探讨听障儿童自我/他人错误信念理解与谎言理解各层面的关系,以及情绪理解在其中的调节作用。实验1采用错误信念理解和谎言理解来探讨自我/他人错误信念理解与谎言理解各层面的关系。实验2增加了情绪理解任务,并探讨情绪理解在错误信念理解和谎言理解之间关系的机制。结果发现：（1）听障儿童他人错误信念理解、真假信息辨别、谎言意图理解的正确率显著不如典型发展儿童,且他人错误信念理解越好,越容易进行真假信息辨别和谎言意图理解;（2）典型发展儿童自我/他人错误信念理解越准确,谎言意图理解越好;（3）当听障儿童情绪理解得分较高时,自我/他人错误信念理解对谎言行为判断具有正向预测作用;（4）典型发展儿童情绪理解得分较高时,自我错误信念理解对真假信息辨别有正向预测作用,他人错误信念理解对谎言行为判断、真假信息辨别有正向预测作用。这些研究结果不仅表明听障儿童他人错误信念理解对谎言理解具有解释作用,而且表明高情绪理解在谎言理解中有促进作用以及表明高情绪理解在对错误信念理解与谎言理解中的调节作用更加显著。     

3～6岁儿童情绪伪装认知能力发展及其与错误信念理解的关系

个体的情绪伪装能力是其情绪社会化发展极为重要的方面,选取某幼儿园123名3～6岁儿童为被试,通过“区分外表-真实情绪”任务和“错误信念”任务考察3～6岁儿童情绪伪装认知能力的发展特点,进而探讨情绪伪装认知与错误信念理解的关系.结果表明：（1）儿童情绪伪装认知能力随年龄增长而提高,3～5岁为儿童情绪伪装认知能力的快速发展期;（2）儿童在消极情境下区分内外情绪的能力显著高于在积极情境中的表现;同时,对两种情绪伪装动机（社会适应、自我保护）的认知能力无显著差异;（3）儿童情绪伪装认知和错误信念理解能力显著相关,两种错误信念（意外内容、意外地点）理解都能很好地预测情绪伪装认知能力.     

简化的联合再认范式中情绪对错误记忆影响的年龄差异

以康奈尔情绪DRM词表为主要实验材料, 使用简化的联合再认范式(DRM范式的变式), 结合多项式加工树建模的统计手段, 对34名年轻人(23 ± 2岁)和28名老年人(68 ± 5岁)的再认记忆进行比较, 以考察不同年龄组中情绪效价对错误记忆的作用机制。结果发现材料的情绪效价对错误记忆的影响存在显著年龄差异：(1) 积极情绪能够有效降低老年人的错误记忆, 其作用机制为积极情绪增强了老年人的字面痕迹而减弱了要点痕迹提取; (2) 消极情绪能够有效地降低年轻人的错误记忆, 其作用机制为消极情绪使年轻人反应偏向降低, 但不影响其记忆痕迹的提取。结果表明, 简化的联合再认范式下, 情绪效价对错误记忆的效应存在明显的年龄差异：老年人表现出积极情绪降低错误记忆的积极偏向; 年轻人表现出消极情绪降低错误记忆的消极偏向; 情绪效应对错误记忆的认知机制存在年龄差异。     

儿童情绪伪装能力的发展研究

该文介绍了国外儿童情绪伪装能力发展及其影响因素的近期研究,这些研究结果表明：儿童最早在斗岁出现情绪伪装的认知能力,6岁时这种能力得到完善;儿童对情绪伪装认知能力和对物理属性的表面与真实的区分能力具有潜在的一致的认知基础;儿童情绪伪装能力的完善和错误信念的获得有关;文化通过社会化过程影响儿童的情绪伪装的发展。     

祖辈协同教养与幼儿错误信念理解能力的关系:亲子依恋与祖辈同住的作用

为考察祖辈协同教养与幼儿错误信念理解之间的关系以及幼儿亲子依恋的中介作用,采用方便抽样的方法,调查了某城市三所幼儿园345名小班至大班的祖辈协同教养幼儿及其家庭教养人。对幼儿使用操作任务考察错误信念理解能力,对其家庭教养人利用自陈式问卷收集家庭教养方式和亲子依恋等数据。结果显示：(1)祖辈协同教养类型显著影响幼儿的错误信念理解水平和亲子依恋,“有祖辈同住”协同教养幼儿的错误信念理解水平以及依恋的安全性均显著低于“无祖辈同住”协同教养幼儿;(2)亲子依恋在祖辈协同教养的民主信任和教养冲突两个维度与幼儿错误信念理解能力之间分别存在显著的中介作用;(3)祖辈协同教养类型在教养冲突、亲子依恋、错误信念理解能力的中介模型中起调节作用,在“有祖辈同住”条件下,协同教养冲突显著负向预测幼儿的亲子依恋安全感。
