Co-speech iconic gestures and visuo-spatial working memory

Three experiments tested the role of verbal versus visuo-spatial working memory in the comprehension of co-speech iconic gestures. In Experiment 1, participants viewed congruent discourse primes in which the speaker's gestures matched the information conveyed by his speech, and incongruent ones in which the semantic content of the speaker's gestures diverged from that in his speech. Discourse primes were followed by picture probes that participants judged as being either related or unrelated to the preceding clip. Performance on this picture probe classification task was faster and more accurate after congruent than incongruent discourse primes. The effect of discourse congruency on response times was linearly related to measures of visuo-spatial, but not verbal, working memory capacity, as participants with greater visuo-spatial WM capacity benefited more from congruent gestures. In Experiments 2 and 3, participants performed the same picture probe classification task under conditions of high and low loads on concurrent visuo-spatial (Experiment 2) and verbal (Experiment 3) memory tasks. Effects of discourse congruency and verbal WM load were additive, while effects of discourse congruency and visuo-spatial WM load were interactive. Results suggest that congruent co-speech gestures facilitate multi-modal language comprehension, and indicate an important role for visuo-spatial WM in these speech–gesture integration processes.     

住院医师医患沟通的问题及对策

医患沟通是新时代住院医师必须掌握的一门技能,是医学人文精神的体现。然而目前我国住院医师由于专业知识及技术的局限性,对医患沟通的认识存在着偏倚,以及我国医学教育缺乏沟通能力的培养,导致住院医师医患沟通能力缺乏,需要提高改善。本文基于当前医患关系以及住院医师医患沟通能力的现状,探讨为提高医疗服务质量,增进医患之间的相互理解和尊敬,创建和谐医疗关系,积极有效防范医疗纠纷,身为住院医师的我们应做些什么,做到什么。     

Prosocial Spending and Subjective Well-Being: The Recipient Perspective

Previous research has demonstrated that people are happier after spending money on others (prosocial spending) rather than spending on themselves (personal spending). This relationship between prosocial spending and well-being has been proved to be reliable across countries and ages. However, the happiness of recipients has been frequently ignored in past prosocial behavior studies, and only a few studies have explored the effect of givers’ voluntary intention on recipients’ well-being and responses. Considering that the purpose of prosocial spending is to benefit both spenders and recipients, this study attempts to investigate the relationships among gift attractiveness, positive perceived intention, willingness-to-accept (WTA) and subjective well-being (SWB) of recipients in prosocial spending. The results of a large scale survey demonstrate that both gift attractiveness and positive perceived intention are positively related to recipients’ willingness-to-accept. And willingness-to-accept is positively associated with recipients’ SWB. More importantly, willingness-to-accept mediates both the relationship between gift attractiveness and SWB, and the relationship between positive perceived intention and SWB. Some implications for theory and practice are discussed.     

精神运动警觉性任务在不同知觉负荷下的疲劳状态监测

精神疲劳是由于长时间的认知活动引起的一种疲劳形式,不同任务水平可能造成不同的疲劳状态。本研究采用双任务范式,利用精神运动警觉性任务(Psychomotor Vigilance Task,PVT)的不同指标,考察了不同任务水平下的视觉搜索任务引起的不同精神疲劳状态。结果发现:PVT任务的最快10%反应时指标与自评疲劳程度结果一致,随着任务持续时间的增加而增加,最快10%反应时能够反映不同任务水平条件下的疲劳状态变化。注意忽视频次指标能够反映简单任务条件下的疲劳状态变化。平均反应时指标的时间主效应和任务主效应都显著,可能是反映精神疲劳状态和任务负荷情况的综合指标。PVT任务的最慢10%反应时指标,仅仅存在显著的任务效应,可能主要体现了任务负荷状态的变化。这些结果表明,PVT任务各指标能够反映不同任务水平引起的疲劳状态的不同变化,是研究和监测不同状态下精神疲劳程度较好的任务选择。     

语义关联性对重复知盲效应的影响：来自汉语成语的证据

重复知盲是在快速系列视觉呈现任务中对第二个重复刺激的加工缺陷。以汉语中反义字和成语为实验材料,采用全部报告任务,探讨刺激的语义关联性对重复知盲的影响。实验1以汉语单字为材料,采用单因素三水平（目标刺激之间的语义关系：无关、相同、相反）被试内设计,结果是重复字产生重复知盲效应,反义字产生语义启动效应。实验2以成语为材料,采用2（目标刺激之间的语义关系：相同、无关）×2（位置：前位置、后位置）设计,结果是语义关联性消解了重复知盲效应。结果表明：（1）反义字不产生重复知盲效应。（2）语义关联性消解成语中重复字的重复知盲效应。（3）实验结果支持竞争假设。     

情绪效价−空间动作隐喻联结对成人和儿童外语情绪词学习的影响

为探究情绪效价与空间动作的隐喻联结如何影响中国成人及学龄前和学龄初期儿童对外语情绪词的学习,要求被试在学习阶段根据情绪效价将新学习的实体外语词卡放在对应空间位置。测试阶段采用二选一迫选任务,记录新词学习的反应时和正确率。结果显示,无论是成人组还是儿童组被试,隐喻一致组在测试阶段中对所学外语词的再认反应时均快于隐喻不一致组和控制组。研究表明,成人和学龄前和学龄初期儿童均存在情绪效价–空间动作隐喻联结的心理表征,并且该联结可以影响成人及学龄前和学龄初期儿童外语情绪词学习效果。     

小学儿童英语课堂学习焦虑发展及其与教师教育行为的关系

运用《外语课堂学习焦虑量表》和《教师教育行为问卷》对399名3～6年级小学儿童英语课堂学习焦虑及他们知觉到的英语教师的教育行为进行了考察。结果发现:(1)小学儿童英语课堂学习焦虑随年级升高而逐渐增长,五、六年级儿童在交际畏惧、考试焦虑、否定评价恐惧方面的得分都显著高于三、四年级儿童;(2)交际畏惧和考试焦虑是我国小学阶段儿童的主要焦虑类型;(3)在英语课堂学习焦虑的三个维度上,男女生差异均不显著;(4)教师的消极反应与评价、鼓励与帮助是预测学生英语课堂学习焦虑的重要变量。研究结果表明,学校、教师和家长应重点关注高年级学生的课堂学习焦虑情况,加强情感疏导,并且教师要多给予学生积极的评价,有助于降低学生的课堂焦虑情绪。     

卫生事业管理专业研究生培养方案探讨

研究生培养方案是研究生培养的规范性文件,对于保证研究生培养质量具有关键的作用.随着社会的发展,培养方案应该及时修订和更新.对美国大学卫生事业管理专业研究生培养计划与国内该专业研究生培养方案进行了对比研究,结果将为进一步修改我国该专业培养方案修订提供借鉴.     

产前超声检查的医学伦理学思考

产前超声检查是指在妊娠期间应用超声检查技术检测母体内胎儿是否存在先天性缺陷和遗传性疾病,随着超声技术的迅速普及和发展,产前超声检查已成为产前诊断的不可缺少的有效手段之一.本文从医学与哲学的角度对产前超声检查的必要性、安全性、局限性以及相关医学伦理问题,如知情同意权、隐私权及人工流产等进行综合分析.
