合作指数与描述方式对儿童囚徒困境博弈中合作行为的影响

本研究采用囚徒困境任务,考察了91名10~12岁儿童和101名成人在博弈决策中合作行为的特点。并分别考察合作指数和描述方式这两个变量对个体合作性的影响。结果表明:(1)描述方式对儿童的合作行为有显著影响,表现为"回避"描述中较之"趋向"描述有更多合作行为,而描述方式对成人则无影响。(2)儿童对合作指数不敏感,平均合作率显著高于成人,表现出合作倾向;成人平均合作率随合作指数的升高而升高,但始终处于几率水平之下,表现出竞争倾向。     

流动儿童家庭环境的特点及其对生活满意度的影响

以北京市1018名流动儿童和447名城市儿童为调查对象,采用家庭生活环境调查问卷、家庭功能问卷、学生多维生活领域满意度量表和学生总体生活满意度量表,考察流动儿童家庭环境的特点及其对生活满意度的影响。结果表明:(1)流动儿童的家庭经济状况和家庭功能均显著差于城市儿童。(2)父亲从事体力类工作显著负向预测流动儿童的环境满意度;家庭生活指数显著正向预测流动儿童的家庭、环境满意度及总体生活满意度;家庭居住的社区环境显著正向预测流动儿童的家庭和环境满意度。(3)家庭亲密度显著正向预测流动儿童的家庭、环境满意度和总体生活满意度,家庭的适应性显著正向预测其家庭满意度。     

儿童假装游戏中假想角色现象初探

通过对145名4~5岁儿童进行结构式访谈,调查幼儿假装游戏中假想角色现象的概况,包括假想同伴和角色扮演现象。结果如下:42.7%的儿童有假想同伴,绝大多数是玩具形式,女孩更多有假想同伴;男孩倾向于选择动物类型的假想同伴,而女孩倾向于人物类型;假想同伴绝大多为同性别并且比自己年龄小。44.8%的儿童有角色扮演活动,其中男孩倾向于装扮动画中的英雄人物,女孩倾向于装扮现实人物。     

学前和小学低段不同识字量儿童的认知能力比较

以193名学前儿童和291名一到三年级小学生为研究对象, 比较了不同年级、不同识字量儿童在语音意识、语素意识、快速命名、视觉技能和正字法意识方面的差异。结果显示, 不同年级、不同识字量儿童分别在语音意识和语素意识的不同层面存在差异, 学前主要表现在音节删除和语素建构任务中, 小学阶段表现在韵母识别、音位删除以及语素判断和语素产生方面;快速命名能力是区分各阶段儿童汉字识别能力的有效指标, 学前儿童的视觉能力与识字量密切相关, 而小学儿童的正字法意识与识字量密切相关。     

探讨人乳头瘤病毒L1蛋白功能及其临床意义

高危型别人乳头瘤病毒（HPV）感染在宫颈癌发生发展中具有重要作用。由于HPV L1蛋白结构特征及其精确的抗原特性,在粘附宿主细胞、识别病毒受体、协助病毒DNA的入胞转运中均发挥重要作用。检测患者宫颈损伤组织中L1蛋白的表达将有助于对患者是否具有传染性进行评估。本文将深刻思考HPV L1功能及其在感染机体并引发癌变的机制,以期更好的解读宫颈癌发病原理并最终应用于,强床治疗。     

论个体差异与诊疗决策

诊疗决策最优化的过程,本质上是针对特定的患者,制定最适合其个体差异的决策过程.对个体差异认知方式,经验医学基于对个体的不完全归纳,循证医学基于对群体随机、双盲、对照、大样本,人类基因组学基于对人类基因的差异表达、单核苷酸多态和复制变异的研究.最优化的治疗方案应体现关注患者心理、社会差异、关注生命质量、远离趋利性等人文特征;体现针对个体病患生物学特性差异、个体病程病期和个体最佳疗效差异等科学特征.

内隐态度之“内隐”的涵义

内隐态度,又称为间接测量态度或自动加工态度。很多学者认为内隐态度是无意识的,需要通过间接测量来获得。但是也有学者认为,当前没有研究可以证明内隐态度内容的无意识性,并且认为内隐态度也并非一定要用间接测量来获得。探讨内隐态度之“内隐”的涵义,对于更好地理解内隐社会认知领域具有一定的借鉴意义。     

Speech errors reflect the phonotactic constraints in recently spoken syllables, but not in recently heard syllables

Adults rapidly learn phonotactic constraints from brief production or perception experience. Three experiments asked whether this learning is modality-specific, occurring separately in production and perception, or whether perception transfers to production. Participant pairs took turns repeating syllables in which particular consonants were restricted to particular syllable positions. Speakers’ errors reflected learning of the constraints present in the sequences they produced, regardless of whether their partner produced syllables with the same constraints, or opposing constraints. Although partial transfer could be induced (Experiment 3), simply hearing and encoding syllables produced by others did not affect speech production to the extent that error patterns were altered. Learning of new phonotactic constraints was predominantly restricted to the modality in which those constraints were experienced.     

Anticipating intentional actions: The effect of eye gaze direction on the judgment of head rotation

Using a representational momentum paradigm, this study investigated the hypothesis that judgments of how far another agent’s head has rotated are influenced by the perceived gaze direction of the head. Participants observed a video-clip of a face rotating 60° towards them starting from the left or right profile view. The gaze direction of the face was either congruent with, ahead of, or lagging behind the angle of rotation. Following this, two static faces, at varying angles of rotation with respect to the end-point angle of the face in the video-clip, were presented simultaneously. The task of the participants was to decide which of the two heads was at an angle best resembling the angle of the end-point of the moving face. The critical test condition consisted of one test face oriented at 10° before, and the other at 10° after the end-point. The ‘lagging behind’ gaze condition elicited a significant underestimation of the rotation compared to the ‘congruent’ and ‘ahead’ gaze conditions. Participants did not exhibit similar biases when judging the rotation of several non-face control stimuli with visual features that mimicked different aspects of gaze direction. The findings suggest that when the gaze direction of a perceived agent is incongruent with the direction of the agent’s head motion observers automatically utilise this discrepancy to adjust their inferences about the agent’s intended heading direction.
