认知信息的详尽度与锚定对决策策略的影响

以191名大学生为被试,采用2×3的完全组间设计,探讨不同认知信息详尽度和有无锚定材料条件下大学生决策策略类型的选择。结果发现:(1)认知信息详尽度对被试的决策策略选择的影响显著,被试在低认知信息详尽度水平下倾向于选择采用维度比较策略,而在高认知信息详尽度水平下倾向于选择采用综合比较策略,并且倾向程度差异显著。(2)锚定效应对决策策略选择的影响不显著,认知信息详尽度与锚定的交互作用也不显著。     

词边界信息和词频在汉语阅读中的作用

利用Eyelink2000眼动仪,记录27名本科生阅读时的眼动轨迹。句子中插入四种空格(正常无空格、词间空格、字间空格和非词空格)标记词边界信息,并操纵目标词的词频,以考察词边界信息和词频在汉语阅读中的作用。结果表明:(1)插入非词空格对低频词的干扰作用大于高频词,插入字间空格能促进低频词的加工;(2)被试对低频词的加工难度均大于高频词;(3)汉语阅读的基本加工单位为词而不是汉字。     

Losing control in front of a fearful face: the effect of emotional information on cognitive control

How is our cognitive control system modulated by emotional information, especially fearful stimuli? An intuitive hypothesis is that fearful stimuli would enhance cognitive control so that people could switch from the ongoing task to emergent events more quickly to secure themselves. To test this hypothesis, we investigated the influence of emotional information on the shift function of cognitive control by using the task-cueing procedure, in which face images were presented as cues. With the gender of faces indicating which task to do, we manipulated the emotional valence of faces (neutral vs. fearful), finding that the switch costs were larger in the trials containing fearful cues than in the trials containing neutral cues (Experiment 1). This effect was not caused by enlarging task-set interference (Experiment 2), nor by slowing down cue encoding (Experiment 3). Contrary to the intuitive hypothesis, our results suggested that the endogenous task-set reconfiguration process was impaired when fearful faces were presented. We speculated that the benefit of decreasing cognitive flexibility in face of fearful stimuli is to speed up response in a dangerous environment, and this accelerating response is achieved by suppressing the goal-directed system to permit the fast, automatic stimulus-driven system to govern behaviours.     

Visual apparent motion can be modulated by task-irrelevant lexical information

Previous studies have repeatedly demonstrated the impact of Gestalt structural grouping principles upon the parsing of motion correspondence in ambiguous apparent motion. Here, by embedding Chinese characters in a visual Ternus display that comprised two stimulus frames, we showed that the perception of visual apparent motion can be modulated by activation of task-irrelevant lexical representations. Each frame had two disks, with the second disk of the first frame and the first disk of the second frame being presented at the same location. Observers could perceive either "element motion," in which the endmost disk is seen as moving back and forth while the middle disk at the central position remains stationary, or "group motion," in which both disks appear to move laterally as a whole. More reports of group motion, as opposed to element motion, were obtained when the embedded characters formed two-character compound words than when they formed nonwords, although this lexicality effect appeared to be attenuated by the use of the same characters at the overlapping position across the two frames. Thus, grouping of visual elements in a changing world can be guided by both structural principles and prior world knowledge, including lexical information.     

工科院校大学生网络成瘾与人格特征的关系

目的了解工科院校大学生网络成瘾现状及其与人格特征的关系,为多方面理解网络成瘾及其矫治提供依据。方法采取随机抽样的方法从西安市某工科院校抽取学生共262人,用网络成瘾量表和艾森克人格量表对研究对象进行测试。结果网络成瘾检出率为41.8%;男生网络成瘾程度显著高于女生;大三、大四学生网络成瘾程度显著高于大一学生,大三学生成瘾程度显著高于大二学生和大四学生;大学生的网络成瘾程度与神经质、精神质呈显著的正相关,与掩饰性呈显著的负相关,与内外向的相关不显著。结论人格特征在一定程度上可以预测网络成瘾的程度。     

大学新生应对方式特点的研究

目的:探讨大学新生应对方式特点。方法:采用应对方式问卷对563名大学新生进行测量。结果:大学新生以使用成熟的应对方式(解决问题、求助)为主;在幻想因子上,性别和专业的主效应显著,女生得分比男生高,文科学生得分高于理科学生得分;在自责因子上,专业主效应显著,文科学生得分高于艺术体育类学生;在求助因子上,生源地的主效应显著,城市大学新生得分高于农村学生。结论:大学新生更多地使用成熟的应对方式;女生比男生更多地使用幻想的应对方式;文科学生比艺术体育类学生更多地使用自责的应对方式;文科学生比理科生更多地使用幻想的应对方式;农村学生比城市学生更少使用求助的应对方式。     

传统民间游戏“葫芦问”促进儿童社会性发展的质性研究

从心理学视角对闽南民间游戏葫芦问进行探究。结果表明:(1)随着游戏次数的增加,儿童情绪调控、自我监控的能力有所提高;(2)游戏领导者与非领导者的助人行为存在明显差异;(3)在葫芦问游戏中,已有知识经验是增加游戏领导者影响力的一大重要因素;(4)游戏促使儿童学会对他人的理解,进而促进了同伴关系的发展。传统民间游戏葫芦问不仅有利于历史文化故事的传播,同时对儿童社会性发展具有促进作用。     

急症产科子宫切除术知情同意的分析

为保留产妇的生命权而牺牲其生育权的子宫切除术,仍是控制产科出血的最后手段。产科急症时,患者本人无法做出意思表示,子宫切除术的知情同意权由其法定代理人行使。子宫切除围术期,实施知情同意,仍存在许多法律盲点及实践困难。本文阐述了产科子宫切除术告知的法律义务、行为主体,以及告知患者子宫切除的方式。     

搞好哮喘控制是一项长期而艰巨的任务

哮喘在全世界是一个严重的公共卫生问题。当哮喘未控制时,哮喘可以影响患者的日常生活质量,甚至可以致命。搞好哮喘控制工作是一项长期而艰巨的任务,在实际工作中应推广以“哮喘临床控制”为核心的哮喘治疗循环模式,即评估患者的哮喘控制水平、治疗并达到哮喘控制、监测并维持哮喘控制。     

妇科手术微创化趋势的人文思考

妇科患者是一个普遍而又特殊的病患群体,心理敏感细腻,追求外在美及女性特征,要求保护个人隐私,对于人文关怀有更高的要求。微创化妇科手术在最小创伤的基础上,最大程度地解除了患者的痛苦,体现了高度的人文关怀,也暴露出一些问题,值得我们关注和思考。
