体型知觉的准确性及其认知机制

体型知觉的准确性既和一般人群的心理健康水平有关,又对进食障碍的理解、预防和治疗具有重要意义。首先,进食障碍患者可能高估自己的身体,其体型知觉准确度可能受其BMI和症状的影响,并与患者预后相关。其次,通过和对他人体型估计的结果进行对比发现,对自己的体型的高估可能受到对自己身体态度因素的影响。第三,一般人群对自己的体型估计的结果往往不一致,这可能是体型知觉的不同量化方式所致。最后,体型知觉准确性的相关认知机制主要有收缩偏差、视觉适应和序列依赖效应。     

Hypercompetitiveness in academia: achieving criterion-related validity from item context specificity

A measurement of a conditional disposition, academic hypercompetitiveness, was created via the contextualization of hypercompetitiveness scale items into situations and circumstances relevant to academic life. An investigation of the construct and criterion-related validity of this new instrument, the Hypercompetitiveness in Academia (HIA) scale, was conducted. The HIA scale was found to be more strongly associated with academic outcomes and achievements than a scale measuring individual differences in a generalized, context-independent, hypercompetitive disposition. Conversely, the generalized hypercompetitiveness scale was found to be more strongly associated with measures of antisocial dispositions. The implications of this research on Horney's (1937) theory of neurosis, the possible negative repercussions of academic hypercompetitiveness, and the study of individual differences through investigations of conditional dispositions were discussed.     

小学高年級学生参加农业劳动中所表現的一些心理特点的初步分析

一、問題的意义和研究的方法 党的教育方針提出后,全国学校普遍地存在着一个新的問題:如何組織学生参加生产劳动,如何把参加生产劳动和对学生的教育工作結合起来。 我們的这一項工作是想分析一下小学高年級儿童参加农业劳动过程中,表現在劳动情况本身、认識劳动中的行为准則、評价自己和別人的劳动情况当中的一些特点,从而对如何通过参加生产劳动对小学高年級儿童进行思想教育提供一些材料。 我們选定北京市蓝靛厂小学的五年級二班作实驗班,与学校合作,共同进行研究。     

不同权力关系对消极特质否定句使用偏向的影响

采用固定反应范式和自由反应范式, 通过创设语用情景, 考察不同权力关系对消极特质否定句使用偏向的影响。结果表明：(1)低权力者评价高权力者时, 被试倾向于使用否定方式(如“不聪明的”), 并认为否定的表述方式合适性较高, 出现否定偏向; 而高权力者评价低权力者, 或者权力平级时则没有否定偏向的出现, 肯定表述(如“愚蠢的”)被更多使用; (2)权力平级时, 社会距离会影响消极特质否定句的使用, 社会距离越远, 消极特质否定句的使用越少; 社会距离越近, 消极特质否定句的使用越多。结果表明, 权力关系与社会距离是影响消极特质否定句使用偏向的重要因素。     

句子加工中语义关联性和句法歧义性实验研究

采用自定速移动视窗技术,探讨语义关联性和句法歧义性对汉语直接宾语、宾语小句类暂时句法歧义句理解加工的影响。结果发现：语义关联性和句法歧义性对歧义区和解歧区的阅读时间有显著影响,并在解歧区产生了显著的交互作用,表明语义信息即时参与对句子的理解加工并同句法信息一起共同影响句子的认知加工过程。     

发展性阅读困难的行为遗传学研究

发展性阅读困难是学龄儿童常见的学习障碍,其病源学问题极其复杂,很多行为遗传学家针对遗传和环境对阅读困难的影响进行了大量的研究。该文对阅读困难的行为遗传学研究进行了回顾,特别是综合介绍了分子遗传学研究所取得的重要成果及不足。最后指出了研究所面临的困难和将来的方向,并对与教育的关系进行了总结与评价。     

Glutamatergic activation of anterior cingulate cortex mediates the affective component of visceral pain memory in rats

Studies of both humans and animals suggest that anterior cingulate cortex (ACC) is important for processing pain perception. We identified that perigenul ACC (pACC) sensitization and enhanced visceral pain in a visceral hypersensitive rat in previous studies. Pain contains both sensory and affective dimensions. Teasing apart the mechanisms that control the neural pathways mediating pain affect and sensation in nociceptive behavioral response is a challenge. In this study, using a rodent visceral pain assay that combines the colorectal distension (CRD)-induced visceromotor response (VMR) with the conditioning place avoidance (CPA), we measured a learned behavior that directly reflects the affective component of visceral pain. When CRD was paired with a distinct environment context, the rats spent significantly less time in this compartment on the post-conditioning test days as compared with the pre-conditioning day. Effects were lasted for 14 days. Bilateral pACC lesion significantly reduced CPA scores without reducing acute visceral pain behaviors (CRD-induced VMR). Bilateral administration of non-NMDA receptor antagonist CNQX or NMDA receptor antagonist AP5 into the pACC decreased the CPA scores. AP5 or CNQX at dose of 400 mM produced about 70% inhibition of CRD-CPA in the day 1, 4 and 7, and completely abolished the CPA in the day 14 after conditioning. We concluded that neurons in the pACC are necessary for the "aversiveness" of visceral nociceptor stimulation. pACC activation is critical for the memory processing involved in long-term negative affective state and prediction of aversive stimuli by contextual cue.     

护士幸福指数及其影响因素调查分析——以汉川市为例

为了解护士幸福指数及其影响因素,采用综合幸福感问卷对汉川市12所医院中206名注册护士进行问卷调查.揭示护士幸福指数处于中等水平,护士幸福指数与综合幸福感各维度、压力、职称等均有显著关联.建议针对情感、支持、压力、职称等相关因素采取适当干预措施提高护士幸福指数.     

核心家庭父亲协同教养对青少年抑郁的影响:父子依恋和母子依恋的中介作用

基于家庭系统理论,采用父亲协同教养、父子依恋、母子依恋和抑郁量表,对河南省某中学初中一、二年级,高中一、二年级共计890名来自核心家庭的青少年进行调查,探索父亲协同教养各维度（团结、一致、冲突、贬低）与青少年抑郁之间的关系,以及父子依恋和母子依恋在二者关系中的中介作用。结果表明：（1）在控制其它维度作用的情况下,父亲协同教养中的团结和冲突对青少年抑郁具有显著的预测作用,一致和贬低对抑郁的预测作用不显著,表明团结、冲突对青少年抑郁具有显著的“独特效应”;（2）团结、一致、冲突、贬低性协同教养均对母子依恋具有显著影响,支持家庭系统中的“交叉效应”;团结、冲突对父子依恋具有显著影响,支持家庭系统中的“外溢效应”;（3）中介效应分析的结果表明,团结、一致、冲突对抑郁的直接效应不显著,母子依恋在团结与青少年抑郁、冲突与青少年抑郁的关系中起到完全中介作用,但父子依恋的中介作用不显著。本研究有助于增进对父亲协同教养的认知,对于指导家庭教育实践、促进青少年心理积极发展具有重要的意义。
