两种视觉特征提示对儿童错误记忆发展的影响

采用DRM研究范式,实验一使用示意图提示,探讨特异性视觉特征对于8岁、10岁和12岁儿童错误记忆的影响及其随年龄而产生的变化;实验二使用位置提示,探讨非特异性视觉特征对8岁、10岁和12岁儿童错误记忆的影响及其随年龄增长而产生的变化。实验结果说明:(1)特异性视觉特征提示会显著减少错误记忆,而非特异性视觉提示则会显著增加错误记忆。(2)8～12岁儿童错误记忆随着年龄的增长而增长,这可能是由于儿童随年龄增长不断地发展其形成要义痕迹表征和要义连接的能力所致。(3)特异性视觉特征提示对8岁儿童错误记忆的影响不显著,对10岁和12岁儿童有显著削弱作用,但这种影响在10岁和12岁儿童间没有显著性地增长。(4)非特异性视觉特征提示对8岁儿童错误记忆不产生显著影响,对10岁和12岁儿童有显著的增强作用,且这种影响从8岁至12岁呈显著性增长。     

汉字字形关联对错误记忆的影响

采用DRM范式,研究汉字字形关联对错误记忆的影响。实验以占汉字主体的形声字为材料。学习阶段使用了两类字表:在一半字表中,各字表内汉字及相应的关键诱饵具有相同形旁;另一半字表中,各字表内汉字及相应关键诱饵具有相同声旁。再认测试中,被试对两类关键诱饵均表现出了明显的错误记忆,并且其效应大小与字表汉字相似度成正比。这些结果说明,汉字的字形关联可以诱发错误记忆现象,并且这种错误记忆效应由汉字间字形相似度决定。     

Limits on efficient human mindreading: Convergence across Chinese adults and Semai children

We tested Apperly and Butterfill's (2009, Psychological Review, 116, 753) theory that humans have two mindreading systems whereby the efficient‐system guiding anticipatory glances displays signature limits that do not apply to the flexible system guiding verbal predictions. Experiments 1 and 2 tested urban Mainland‐Chinese adults (n = 64) and Experiment 3 tested Semai children living in the rainforests of Peninsular Malaysia (3‐ to 4‐year‐olds, n = 60). Participants – across different ages, groups and methods – anticipated others’ false‐beliefs about object‐location but not object‐identity. Convergence in signature limits signalled that the early‐developing efficient system involved minimal theory‐of‐mind. Chinese adults and older Semai children showed flexibility in their direct predictions. The flexible mindreading system in ascribing others’ beliefs as such was task‐sensitive and implicated maturational and cultural contributions.     

错误记忆产生的认知与神经机制：信息加工视角

采用信息加工视角, 在划分不同信息来源的基础上分析编码、存储(巩固)、再激活/再巩固和提取的一系列加工过程如何导致错误记忆形成, 由此总结出错误记忆产生的三个可能原因：(1)因缺乏针对目标事物特异性细节的记忆表征而侧重于编码和提取目标和非目标事物共享的抽象记忆表征, 使被试更倾向于依赖抽象表征对缺失的目标细节进行重构, 引发错误记忆; (2)目标事物启动了对应图式, 导致与图式相关的非目标事物记忆表征得到增强, 引发错误记忆; (3)误导信息干扰了再度激活状态下目标事物的记忆表征, 妨碍其进行准确的记忆再巩固, 从而引发错误记忆。未来研究可进一步探讨目标事物特异性细节的表征区域、不同类型的图式表征促进非目标事物记忆表征的具体机制以及提取阶段的图式复现对错误记忆形成的影响等问题。     

The Role of the Self in False Memory Creation

Summary

People will create false memories of childhood experiences. In this article, the research that demonstrates the creation of false memories is first described. Three processes that may be involved in memory creation are then outlined. First, individuals must accept a suggested event as plausible. Second, they construct an image and narrative of the false event. Third, they incorrectly attribute the source of the event to personal memory rather than external suggestion. We argue that the self plays a role in each of these processes. In addition, because memories are important components of the self, when memories change, the self changes as well.     

Separation—Individuation,Self-Concept,and Object Relations in Fraternal Twins,Identical Twins,and Singletons

Identical twins, fraternal twins, and singletons (n = 30 in each group) were compared on objective measures of separation–individuation, object relations, and self-esteem. No significant differences were found. The data did not support the popular notion that twins face special problems with respect to personality development or the idea that twins have more difficulty than others in establishing and maintaining close relationships. Twins and nontwins did not differ significantly with respect to marital status, number of years married, whether married before, number of previous marriages, number of years divorced, or living arrangements if single. The majority of twins had been raised in a way that encouraged at least some individual differences.     

Counter‐Interrogation Strategies when Anticipating Questions on Intentions

The present experimental study adds to the emerging line of psycholegal research focusing on true and false intentions. It is the first to examine mock suspects' (N = 120) counter‐interrogation strategies in investigative interviews in which they anticipate questions on their intentions. As planning is an inherent part of many intentions, mock suspects were, in addition to questions on their intentions, asked a set of questions that pertained to the planning phase in which they formed their intentions. Besides ratings of the anticipation and difficulty of the questions, participants were asked to provide their principal strategy for being perceived as truthful. Both truth tellers and liars perceived the questions on the planning phase as significantly more unanticipated than the questions on their intentions. Furthermore, liars perceived the questions on the planning phase as more difficult to answer than did truth tellers. Liars and truth tellers differed with respect to their principal strategy employed for being perceived as truthful. Liars' most commonly used strategy was to stick to the cover story, whereas truth tellers' most common strategy was to be honest. The results are discussed in relation to the unanticipated questions approach and psychological concepts such as the illusion of transparency. Copyright © 2012 John Wiley & Sons, Ltd.     

虚假医疗信息的道德缺失与伦理重建

伴随着经济和信息技术的发展,医疗信息环境的污染和失衡已严重影响到了医疗卫生事业的健康发展。从虚假医疗信息的表现入手,剖析了虚假医疗信息产生的根源,着重分析了虚假医疗信息的道德缺失,从实际出发提出了具有可操作性的伦理道德重建。     

特质标签对儿童错误信念理解的影响

该研究将错误信念任务中主人公加上"聪明"或"笨"的标签,以考察特质标签是否会影响儿童对错误信念的理解。360名5~8岁儿童参加实验,每个年龄组儿童随机分配到"聪明"标签组、无标签组和"笨"标签组。结果表明:(1)"聪明"标签会极大地阻碍67、岁儿童理解他人错误信念,对5、8岁儿童没有影响;(2)"笨"标签对所有年龄组儿童错误信念的理解都没有产生影响。
