交互式认知：隐性知识的认知机制

在社会建构论和分布式认知等相关理论的基础上,结合隐性知识的特点提出了交互式认知理论,目的在于揭示隐性知识的认知机制。交互式认知是指不同知识主体认知的相互影响和相互作用的过程,其中师傅带徒弟和实践社区这是企业管理实践中最为常见的两种隐性知识传播形式,

Cold and lonely: does social exclusion literally feel cold?

Metaphors such as icy stare depict social exclusion using cold-related concepts; they are not to be taken literally and certainly do not imply reduced temperature. Two experiments, however, revealed that social exclusion literally feels cold. Experiment 1 found that participants who recalled a social exclusion experience gave lower estimates of room temperature than did participants who recalled an inclusion experience. In Experiment 2, social exclusion was directly induced through an on-line virtual interaction, and participants who were excluded reported greater desire for warm food and drink than did participants who were included. These findings are consistent with the embodied view of cognition and support the notion that social perception involves physical and perceptual content. The psychological experience of coldness not only aids understanding of social interaction, but also is an integral part of the experience of social exclusion.     

急性有机磷农药中毒救治中的几个问题

解决急性有机磷农药中毒病死率居高不下的问题,必须提高救治中的辩证思维。正确理解标本兼治的含义,外周性、中枢性抗胆碱药物和复能剂联合应用,合理维持阿托品化,积极应用机械通气进行必要的呼吸支持治疗和适时行血液灌流治疗是救治有机磷农药中毒的有效保证。     

古代风水辨

“风水”是一种传统文化,是人们对居住环境进行理性选择的行为规范,体现着一种哲学意义上的精神追求。作为一门古老的环境文化,它源于先民对自然的敬畏和对美好生活的向望,虽然由于历史条件的限制,其中不乏一些迷信的成分,但就整体而言,古代风水文化更多的是倡导人与自然的和谐相处     

儿童在困难情景中的情绪反应

以80名二、五年级儿童为被试,采用临床访谈法,考察在困难情景中儿童的情绪反应,包括情绪类型、情绪表达、表达与否的理由和后继行为。结果表明:1)儿童报告羞愧/伤心多于生气,倾向于表达情绪,在解释是否表达情绪的原因时主要强洞自我保护和强调事实等理由,主要采取改变情景的后继行为。2)儿童倾向于表达生气,不表达羞愧/伤心。3)儿童对情绪反应各变量的认知还存在性别、年级和观众类型的个体差异。     

Contagion or restitution? When bad apples can motivate ethical behavior

When there is a “bad apple” in the group, are we more likely to follow the example or compensate for their sins? Three experiments showed that whether a group member’s unethical actions lead to contagion or restitution depends on the presence of out-group observers. In Experiment 1, participants were more likely to compensate for the transgression of an in-group member than an out-group member when there were out-group observers. Experiment 2 varied the presence of out-group observers and showed that such compensatory behaviors occur only in the presence of out-group members. We suggest that the presence of out-group observers trigger a self-categorization process that induces guilt in individuals for their group members’ transgressions. Indeed, associated guilt mediated the relationship between in-group member’s unethical behavior and participants’ compensatory behavior (Experiment 3). These results suggest that norms implied by others’ behavior and group categorization are important determinants of ethical behavior.     

假字的Stroop效应:汉字部件对颜色命名的影响

通过变化左、右部件和上、中、下部件而制作的假字,采用两因素被试内设计,共80名大学生参加两个实验,考察汉字部件的Stroop效应。结果发现:(1)由"红"、"黄"两字不同部件所构成的假字分别影响对红、黄颜色的命名;(2)不同位置的部件所构成的假字,其产生的Stroop效应不同,即左部件比右部件,上部件比中、下部件产生的影响更明显。最后在平行分布式加工模型的范畴内讨论了其加工机制。     

刺激呈现次数和位置对纯粹接触效应的影响研究

纯粹接触效应是指个体接触一个刺激的次数越频繁,个体对该刺激就越喜欢的现象。本文通过两个实验考察刺激的呈现次数与位置对纯粹接触效应的影响。实验1讨论了纯粹接触效应与刺激呈现次数之间的关系,发现刺激的偏好程度和再认成绩在不同的刺激呈现次数水平上都具有显著性差异。实验2讨论了纯粹接触效应与刺激呈现位置之间的关系,结果发现不同呈现位置上刺激的偏好程度不具有显著性差异,而再认成绩之间具有显著性差异。     

高、低强迫症状个体的词语再认差异

比较了高强迫症状（High obsessive compulsive symptom, HOC）和低强迫症状（Low obsessive compulsive symptom, LOC）被试对于不同类型词语（强迫症敏感词、情绪词和中性词）再认成绩和记忆信心的差异。结果发现,HOC组记忆保存量显著低于LOC组（p<0.05）,表明HOC组对强迫症敏感词存在一定的偏好;通过对被试反应信心的检测和信号侦察论的应用,发现HOC组对中性词再认正误的判断觉察能力（d’值）低于LOC组（边缘显著：p＝0.054）;在正确反应信心上,被试类型和词语类型间存在交互作用,F(1,22)=4.60,p<0.05。本研究认为HOC组辨别能力的缺损可能导致其记忆信心方面的降低,这种假设还需要进一步的认知和脑功能研究来证实。
