去甲肾上腺素对习得性长时程突触增强的影响

在大鼠条件性饮水反应的建立和巩固过程中,在每天训练之前,通过预先与记录电极一起埋植在海马齿状回的注药管,微量注射去甲肾上腺素(NE),观察其对海马齿状回的习得性长时程突触增强的影响。结果表明:NE能增强突触效应;训练作业前注NE易化了习得性长时程突触增强的形成,但对其巩固无影响;同时相应地易化了动物条件反应的建立。提示NE参与海马齿状回的习得性长时程增强的形成。本文对其可能的作用机制进行了讨论。     

The facilitative effect of positive stimuli on 3-year-olds’ flexible rule use

This study examined the effect of emotional stimuli on 3- to 4-year old children's flexible rule use, as measured by the Dimensional Change Card Sort (DCCS). In Experiment 1, children in two countries (Canada and China) were given 2 versions of the DCCS. The Standard version required children to sort red and blue boats and rabbits first by shape and then by color (or vice versa); the Emotional Faces version required children to sort happy and sad male and female faces first by emotion and then by gender (or vice versa). Children performed significantly better on the Emotional Faces version, and performance on the 2 versions was related. Order in which dimensions were presented had no effect. Experiment 2 examined which aspects of the emotional faces were responsible for the facilitation of children's performance. Performance on the Standard version was compared to performance on three contextual faces versions, in which children were shown happy, sad, or neutral faces and required to sort them by age (child versus adult) and then by gender (or vice versa). Facilitation was only seen in the context of happy faces. Results are consistent with the suggestion that positive stimuli promote cognitive flexibility, perhaps by increasing dopamine levels in prefrontal cortex.     

儿童学校适应的分类及判定

以6579名小学三、五年级学生为被试,采用聚类分析和判别分析方法,结果表明:(1)根据儿童学校适应的指标将儿童的学校适应状况分为良好型、闲适型、紧张型、高危型四种类型.(2)良好型的儿童,在学业自我评估、学业动机和心理健康水平三个水平上的得分为正向,在问题行为上的得分为负;高危型儿童的结果与适应良好型的儿童完全相反;而在闲适型的儿童中,学业动机为负、心理健康水平为正;在紧张型的儿童中,学业动机为正向、而心理健康水平是负向的.(3)建立儿童学校适应的判别函数,为儿童在教育和心理问题进行指导提供了初步诊断依据,同时也对有关学校适应的研究提供新的视角.     

We Believe in Being Honest: Examining Subcultural Differences in the Acceptability of Deception1

Perceptions of lie acceptability vary as a function of the motivation for the lie, the relationship between deceiver and deceived, and the perceiver's cultural background. The current study examines the relation between one cultural background—that is, the Church of Jesus Christ of Latter‐Day Saints (LDS)—and perceptions of lie acceptability, and whether this varies as a function of lie and rater characteristics. Participants rated lie acceptability in 12 scenarios varying lie motivation and lie recipient. Overall, the LDS group rated lies as less acceptable than did the non‐LDS group, and lie acceptability varied according to lie motivation and lie recipient. Participant age was negatively correlated with lie acceptability. Implications of the findings and directions for future research are discussed.     

归因训练在精神卫生领域的应用

归因训练是一种从归因方式入手对认知、情绪和行为问题进行治疗的认知行为治疗方法。综述了归因方式在精神分裂症、神经症、物质滥用、生理心理问题及家庭暴力等精神卫生领域中的作用,以期对归因训练在相关领域的应用提供新的思路。     

市民人格特征及其与心理健康的关系研究

为探讨南京市民人格特征及其与心理健康的关系,对南京市民进行抽样调查。结果显示南京市民的人格特征较一般人群更外向,掩饰程度较高;性别、年龄、职业以及文化程度与人格特征存在一定关系;不同人格类型的市民心理健康水平不同;年龄、情绪稳定性及内外向性对心理健康有预测作用。     

协作还是斗争——心理障碍治疗百年

长期以来,在心理障碍治疗领域存在着心理治疗师与精神科医生的相互斗争,从协作的角度对心理治疗百年史进行回顾,认为百年心理治疗史实际上是心理医生与临床医生相互斗争走向协作的历史.这一过程可大致区分为自发、附属、斗争到整合四大阶段.就长远来看,在心理障碍的治疗中,这两类专业人员的相互配合是不可避免的.     

医生职业倦怠及社会、组织影响因素的探讨

医生是职业倦怠研究最早关注的职业之一,通过回顾国内外相关研究,分析了医生职业倦怠的现状,并认为我国现阶段医生的职业倦怠与医疗政策、法制层面存在缺憾、经济和心理回报不够、价值观冲突、缺乏控制、角色冲突等有关.呼吁从社会、组织层面深入研究我国医生的职业倦怠.     

性别与阿尔茨海默病相关性的研究进展

阿尔茨海默病(AD)是以近期记忆障碍为主要临床症状,以老年斑及神经纤维缠结为主要病理改变的进行性神经变性疾病.目前发现男女患病率有明显差异,女性患病率是男性的1.5倍～3倍,这可能是由于绝经后妇女体内雌激素不足增加了AD的易感性,而男性血清总睾酮降低,能使AD患者病情恶化.     

处理疼痛的理念

处理疼痛的理念各有不同.有人认为手术后疼痛很正常,挺着吧.人老了,腰腿痛就该扛着.而有的人会积极给予止痛治疗,以患者舒适为目标.2007年7月我国卫生部签发了关于《医疗机构诊疗科目名录》中增加"疼痛科"的文件,说明我国进入了一个止痛治疗的新时代.得到疼痛治疗是患者的基本权利,也是医师的崇高职责.有疼有痛忍着不治的时代即将过去,及早、及时为患者止痛是人道主义的体现.
