关系认知与善意认知对大学生人际信任的影响

采用投资博弈,以大学生为被试探讨关系认知（亲疏关系、阶层关系）和特质认知（以善意为例）对中国人人际信任的影响。结果发现,亲疏关系认知、阶层关系认知和善意认知都会影响中国人的人际信任。关系越近、阶层越高、越善意,信任水平越高。随着亲疏关系下降或善意降低,阶层关系对信任水平的作用之间的差异逐步减弱。亲疏关系认知和阶层关系认知存在交互作用,亲疏、阶层和善意也具有交互作用。人们对上位阶层的信任大于平位大于下位,但是当信任对象存在低善意特质或陌生人身份时,人们对上位阶层的信任会下降至和平位没有差异;当低善意特质和陌生人身份同时存在时,人们对上位、平位和下位的信任无差异。

道教音乐养生的机理研究

中国传统音乐蕴涵丰富的道文化.道教音乐的神是虚静柔和的韵,形是五音六律;神通于心,故韵可修心养性;形合于阴阳五行,故五音六律能调养五脏六腑而炼形养命.道教的性命双修,从传统医学而言是形神共养,从现代医学而言是心身并调.本文从道教的性命双修、传统医学的形神观及现代心身医学等多重角度探讨了道教音乐的养生作用.     

注视-西蒙效应的空间编码机制

采用注视-西蒙范式探讨了注视方向知觉的空间编码机制。实验一让被试采用双手交叉的反应方式,发现注视-西蒙效应并不随反应手的交叉而反转,说明它涉及抽象的空间方向编码,而非基于以手为参照系的半侧优势效应。实验二采用纯音音调辨别任务,发现了典型的注视-西蒙效应,结合实验一视觉通道的结果,说明注视-西蒙效应并非特异于视觉通道,它可能发生在晚期的反应选择阶段,而非早期的知觉阶段。结果支持注视线索能够自动诱发观察者形成抽象的方向表征的观点。     

语境预测性对阅读中字词加工过程的影响：眼动证据

研究包含3项实验, 通过观察语境预测性与目标词汇的整词词频、词内汉字字频间交互作用, 以探讨阅读中语境预测性如何影响中文词汇加工问题。研究以双字词为例, 实验1操控目标词汇的语境预测性与整词词频, 结果发现, 语境预测性与整词词频交互作用不显著。实验2操控目标词汇的语境预测性与首字字频, 结果发现, 语境预测性与首字字频交互作用不显著。实验1和实验2的贝叶斯分析都倾向于支持交互作用不存在假设。实验3操控目标词汇的语境预测性与尾字字频, 结果发现, 语境预测性与尾字字频交互影响首次注视时间、凝视时间、总注视时间和再注视概率。由此可知, 语境预测性与整词词频、首字字频变量相对独立地影响词汇加工; 语境预测性直接影响词内汉字(尾字)的加工过程。     

Maternal supplementation of nucleotides improves the behavioral development of prenatal ethanol-exposed mice

Maternal ethanol consumption during pregnancy can induce learning deficits in the offspring. The objective of this study was to assess whether supplementation of exogenous nucleotides during pregnancy and lactation would ameliorate prenatal ethanol-induced learning and memory deficits in the offspring of mice, and to explore the possible mechanisms. In the present study, pregnant C57BL/6J mice were exposed to ethanol (5 g/kg body weight) intragastrically from gestational day (GD) 6 to GD15. The dams in exogenous nucleotide intervention groups were fed with feed containing 0.01 %, 0.04 %, or 0.16 % nucleotide powder, with control and ethanol groups receiving normal feed. The dams were allowed to deliver naturally and to breast feed their offspring. After weaning, behavioral tests were carried out in the offspring of each group. Serum oxidation indexes were analyzed, and the hippocampus of each offspring was collected and detected for acetyl cholinesterase (AChE) activity and the expression of p-CREB, CREB, and BDNF. The results showed that maternal supplementation with exogenous nucleotides during pregnancy could ameliorate prenatal ethanol-induced learning and memory deficits in the offspring of mice, through improving their antioxidant capacity, reversing hippocampus AChE levels, and allowing the expression of some proteins related to learning and memory. However, different sensitivities were found between the two sexes.     

群体印象形成与个体印象形成：反基准比率效应

采用 “反基准比率效应”范式考察在群体印象形成与个体印象形成两种认知加工过程中, 基准比率对印象形成过程及其结果的影响。被试分别为39名19~25岁大学生(实验1：男生17名, 女生22名, 均为右利手)以及46名19~25岁大学生(实验2：男生21名, 女生25名, 均为右利手)。结果发现：无论是群体印象形成还是个体印象形成, 在学习阶段, 知觉者都能准确认知各类事件间的关系, 但会优先建构高频事件间的联结。而在测试阶段, 当低频事件与高频事件同时出现时, 知觉者发生明显关系误判, 即以反基准比率的倾向高估低频事件间的联结强度。实验表明群体与个体印象形成过程中都会产生反基准比率效应这样的加工偏差, 进而初步揭示反基准比率现象在社会信息加工领域具有一定的普遍性。     

观察式学习条件下类别维度与家族相似性类别学习

在观察式学习条件下考察类别维度数量（三维度类别、六维度类别、九维度类别）,类别维度结构（线性分离结构、非线性分离结构）的变化对家族相似性类别学习的影响。结果表明：观察式学习条件下,类别维度数量的变化对样例学习无影响,对特征学习有影响,表现在特征正确再认数量上有差异,但特征再认正确率上无差异;类别维度结构的变化对样例学习有影响,对特征学习无影响,表现在样例正确再认数目上线性结构大于非线性结构。     

内隐自尊探析

作为内隐社会认知领域的一部分,内隐自尊是指人们在对与自我相关或自我分离的客体进行评价时的一种态度表现,而这种态度无法通过内省的方式被意识到。目前,内隐自尊的研究在方法采用间接测量的方式;在研究成果上主要集中于内隐自尊与外显自尊的对照性研究,内隐自尊的应用性研究两方面。本文拟就内隐自尊研究的缘起、研究方法、已有研究成果作尝试性探讨。     

Working memory biasing of visual perception without awareness

Previous research has demonstrated that the contents of visual working memory can bias visual processing in favor of matching stimuli in the scene. However, the extent to which such top-down, memory-driven biasing of visual perception is contingent on conscious awareness remains unknown. Here we showed that conscious awareness of critical visual cues is dispensable for working memory to bias perceptual selection mechanisms. Using the procedure of continuous flash suppression, we demonstrated that “unseen” visual stimuli during interocular suppression can gain preferential access to awareness if they match the contents of visual working memory. Strikingly, the very same effect occurred even when the visual cue to be held in memory was rendered nonconscious by masking. Control experiments ruled out the alternative accounts of repetition priming and different detection criteria. We conclude that working memory biases of visual perception can operate in the absence of conscious awareness.
