关于幼儿对损人行为的道德判断及有关情绪预期的初步研究

以幼儿易于理解的有关享用财物的小故事,对４、５、６岁儿童作个别随访,综合考察其已获得的道德知识和道德认知的特点,以及相关情绪预期的情况。结果表明：１．幼儿已经获得了有关社会道德的最初步的知识,并能运用这些日常概念水平的知识对行为作道德判断,其道德认知已出现关心他人利益的成分,自我中心主义不突出;２．幼儿假设自己作为损人者的情绪预期与对故事中损人者的情绪预期之间存在明显差异,道德认知与道德情感脱节的现象在前者未有明显表现,却在后者中显现出来。     

论疾病的假象

疾病假象是疾病本质的特殊表现形态,是影响临床思维、导致误诊误治的重要制约因素之一。显而易见,研究疾病假象问题,探讨疾病假象的内涵规定和疾病假象一般特点;疾病假象的基本类型和疾病假象的成因分析;疾病假象的识别途径和疾病假象的辨析方法等等,对于提高临床思维水平和医疗质量,有着重要意义     

恶性肿瘤动物模型的建立

建立恶性肿瘤动物模型是医学科研工作者重要的研究手段。恶性肿瘤的自发肿瘤模型,诱发肿瘤模型和移植肿瘤模型有着各自的机体与外界施加因素之间对立平衡,对界因素逐渐同体所转化和接纳,最终导致肿瘤形成,同时机体也荷瘤。因此,任何影响动物和施加固的条件均可促进和减弱肿瘤形成的起始,进展,结局。就三种恶性肿瘤动物模型建立过程中启示呈现出来,并对不同模型特点和选择进行评述。     

Symbolic forms can be mnemonics for recall

Form symbolism using squares and circles can aid recall. In Experiment 1, subjects saw 20 words, each presented in a circle or a square. Words like SOFT and MOTHER were presented in circles in the “congruent” condition, whereas the same words were presented in squares in the “incongruent” condition. Two experiments revealed that words in the congruent condition were more likely to be recalled. A comparison of the conditions with a baseline condition, in which 20 listed words were not closely related to either of the shapes, suggests that the effect was more likely due to facilitation produced by the congruent condition than to inhibition from the incongruent condition.     

指向具体人物对象的人际信任:跨文化比较及其认知模型

本文对指向具体人物对象的人际信任作了跨文化实证比较研究,并探讨了人际信任的认知模型。使用人际信任行为量表(ITBS)测量了中国、香港及美国三地大学生的人际信任。根据三组被试对诸如父亲、哥哥、同班同学、医生和陌生人等20个人们生活中经常能够接触的人物信任程度的高低,可将这些具体人物对象归为“亲人”,“熟人”和“陌生人”三个群体。三组被试对“亲人”群体的人际信任没有显著差异,但中国被试对其它两个人物对象群体的信任要高于美国和香港被试,而后两组被试的差别则不显著。另外,利用多元回归法在人际信任与六种认知变量间建立了模型关系,发现其中只有两个变量对模型作出主要贡献,即:(1)对由信任行为而得到得回报的期望值越高;(2)得不到回报而引致损害的严重性评估越低,则一个人作出某一信任行为的可能性就越大。被试的文化背景和社会工业化程度对人际信任认知模型没有影响。     

Associative structure of differential inhibition: implications for models of conditioned inhibition

Following A+/X- training (with A, X, and + being a light, tone, and footshock, respectively), rats received extinction of A and the training context, extinction of the training context alone, or no extinction. The inhibitory potential of X was then assessed with conditioned lick suppression in a neutral context using both summation and retardation tests. Extinction of the training context alone and extinction of A and the training context reduced the inhibitory potential of X appreciably and equally. Hence, what is traditionally called differential inhibition appears to depend not on the excitatory value of A but on the excitatory value of the training context. In conjunction with what is known about other inhibitory training procedures, these results suggest that a conditioned inhibitor is a stimulus that has been paired with little or no reinforcement in the presence of an accompanying stimulus that predicts greater reinforcement.     

推进新时代中国社区心理学新形态建设

建设中国特色的社区心理学是时代的呼唤和要求。在党的二十大精神指引下,新时代中国社区心理学需要坚持中国化时代化的马克思主义为指导以推进理论建设;以新时代社区心理建设为场域,助力社会主义核心价值观培育;构建新时代中国社区心理学服务路径,助推人民共同富裕。总体而言,中国特色社区心理学的理论建设与实践探索需要关注新时代社区发展中涌现出的新问题,提出解决中国社区发展问题的中国办法和中国方案,努力推进中国社区心理学新形态的建设。     

Political distrust,perceived threat,and intentions to engage in normative and violent collective action: A mixed-methods study

In three studies, we examined the role of distrust and perceived threat in intentions to engage in normative and violent non-normative collective action. A field-based qualitative study of 35 pro-democracy protestors during the 2019 Hong Kong Anti-Extradition protests revealed that perceived threat to Hong Kong values alongside distrust of political institutions spurred collective action engagement and support for defensive violent collection action. In Study 2, a questionnaire (N = 639) testing pro-democracy action intentions demonstrated direct paths on both normative and violent collective action intentions from distrust and threat. In Study 3 (N = 133), experimental trust and threat manipulations demonstrated a significant association between distrust and threat on violent collective action intentions and acceptance, and a significant interaction on acceptance of violent collective action. Our results reveal the importance of distrust and threat in attitudinal support for, and engagement in, collective action and their role in transitioning from non-violent to violent collective action.     

腹内侧前额叶在内隐认知重评中的因果作用

情绪调节对维持个体心理健康、适应社会生活十分重要, 然而以往研究主要关注外显情绪调节, 目前我们对内隐情绪调节的认知神经机制的了解还非常有限。为揭示内隐情绪调节的核心脑区, 本研究使用句子整理任务启动内隐认知重评, 并采用经颅直流电刺激(transcranial direct current stimulation, tDCS)激活内侧前额叶特别是腹内侧前额叶(ventromedial prefrontal cortex, vmPFC), 考察该脑区在内隐情绪调节中的因果作用。结果表明, vmPFC被激活的被试组(实验组, n = 40)在内隐认知重评启动条件下比tDCS伪刺激组(对照组, n = 40), 在观看负性图片时报告了更少的负性情绪, 同时负性图片诱发的晚正成分(late positive potential, LPP)波幅更低(LPP是情绪体验强度的客观指标)。同时, 实验组比对照组在观看负性图片时表现出更低的枕区P1波幅(P1为早期视觉注意程度的客观指标)。以上结果说明, 激活以vmPFC为代表的内侧前额叶不但能增强内隐情绪调节的效果, 还能减少被试对负性刺激的早期注意分配。本研究是采用tDCS技术考察启动引起的内隐情绪调节的首次尝试, 研究结果不但表明了以vmPFC为代表的内侧前额叶在内隐认知重评中的关键作用, 还为临床应用研究指出了增强内隐情绪调节能力的神经调控潜在靶点。     

朗读流畅性在儿童阅读发展中的预测作用

本研究对八个班的二年级汉语儿童进行了长达一年的追踪,深入探索了朗读流畅性在儿童阅读发展中的作用。结果发现,篇章朗读流畅性与学生的多项言语和阅读能力正相关;在控制了年龄、瑞文推理、汉字识别和口语词汇量之后,只在三年级时发现了篇章朗读流畅性对同时期的阅读理解有独特解释作用,但未能在二年级时找到类似的横断证据;但在排除了自回归效应和其他变量的作用之后,二年级时的朗读流畅性对一年后的阅读理解具有独特的预测作用。这表明朗读流畅性在汉语儿童阅读能力发展中具有重要预测作用,今后的理论研究和教学实践都应对此给予足够重视。
