判断与决策中的规划谬误

规划谬误是指人们在估计未来任务的完成时间时, 倾向于过度乐观, 低估任务完成时间的一种现象。规划谬误的心理机制主要包括规划谬误理论和记忆偏差理论。规划谬误的影响因素主要有认知因素、动机因素、个体的经验水平、目标任务的性质等。规划谬误的应对策略主要有与过去的经验相联系、从第三人称视角进行估计、任务分解及时间分配。未来的研究主要从规划谬误与策略性误解、乐观偏差、过分自信的关系, 规划谬误的产生根源、规划谬误的跨文化研究、规划谬误的研究范围及应用领域等方面进一步探讨。     

基于面孔知觉的刻板印象激活两阶段模型

从个体建构研究视角出发, 考察了基于面孔知觉的刻板印象激活过程。实验一比较了性别分类判断、启动范式以及同时呈现范式下刻板印象匹配性判断三者所用反应时的差异, 结果发现, 后者显著地大于前二者, 且等于前二者之和; 面孔倒置呈现使同时呈现范式下刻板印象匹配判断的反应时和错误率显著增大, 但其对启动范式中刻板印象匹配判断的反应时和错误率没有影响。实验二基于同时呈现范式, 通过不同程度的面孔变形来操纵性别类别提取的难度, 更精确地探讨了基于面孔知觉的社会类别信息提取过程对刻板印象激活的影响, 结果表明, 随着从面孔中提取类别信息难度的增加, 刻板印象激活所用的反应时也逐渐增大。研究结果证实了研究者所提出的刻板印象激活两阶段模型, 即基于面孔知觉的社会类别提取阶段和刻板印象信息激活阶段, 证实社会类别激活和刻板印象信息激活是两个分离的过程, 以社会类别信息提取为目的的面孔知觉对刻板印象的激活有显著影响。     

工作幸福感：概念、测量水平与因果模型

工作幸福感是个体工作目标和潜能充分实现的心理感受及愉悦体验, 是一个需要组织和个人持久努力和投资的动态过程, 包括工作投入、心流体验、工作旺盛感、工作满意度、工作积极情感等宽泛的结构。有必要从暂时、个体和单元三个水平对工作幸福感进行研究。随着研究方法的进展, 工作幸福感的研究呈现出个体差异和个体内波动结合的趋势。工作幸福感多水平动态形成机制模型整合了组织和工作环境因素、个人特征以及人与环境的交互作用, 体现了工作幸福感的动态特征, 解释了人类基本心理需要的满足是工作幸福感形成的心理机制。外溢?交叉动态模型解释了幸福感在不同生活领域的外溢以及在工作团队成员或家庭配偶之间的传递, 有助于推动工作幸福感不同测量水平的效应研究。未来需要通过实证研究检验工作幸福感的动态因果模型, 探讨不同水平的工作幸福感对绩效的影响机制, 更多地研究心流体验、心理旺盛感、高兴和自豪等工作幸福感指标, 加强对工作幸福感的干预研究。     

老年刻板印象威胁及其研究操纵

随着人口老龄化的不断加剧, 老年刻板印象威胁受到越来越多的关注。不同于种族或民族、性别等刻板印象威胁, 老年刻板印象威胁表现出累积性、共通性与连续性等特征。目前关于老年刻板印象威胁的研究多集中于认知老化尤其是记忆老化上, 关注老年刻板印象威胁对老年司机和老年员工的消极影响。消除与降低老年刻板印象威胁的消极效应可以从认知改变、群体认同、代际接触、老龄自我实现和个性化以及媒体宣传等五个方面来进行。在实验室研究中, 老年刻板印象威胁有外显与内隐两种不同的操纵形式。未来可以从扩展研究领域、细化“年龄”差异、比较整体效应大小和性别差异、侧重积极效应以及加强本土化检验和跨文化比较研究等方面来深化。     

情境事件、关系取向与人际关系满意感的关系

该文采用问卷方法探讨了情境事件、情绪和关系取向与人际关系满意感的关系。研究结果显示,年龄、性别和职业均影响着人们对关系满意感两个维度的评价。消极事件直接影响个体对关系不满意维和满意维的评价,导致个体的不满意感产生,而积极事件则只能通过情绪间接的影响着个体对关系的评价。关系缘分观能够解释人际关系满意感。结论：情境事件和关系取向均影响着人们对自身人际关系满意感的评价。     

Disentangling perceptual and motor components in inhibition of return

Following an abrupt onset of a peripheral stimulus (a cue), the response to a visual target is faster when the target appears at the cued position than when it appears at other positions. However, if the stimulus onset asynchrony (SOA) is longer than approximately 300 ms, the response to the target is slower at the cued position than that at other positions. This phenomenon of a longer response time to cued targets is called "inhibition of return" (IOR). Previous hypotheses propose contributions of both response inhibition and attentional inhibition at cued position to IOR, and suggest that responding to the cue can eliminate the component of response inhibition. The current study uses tasks either executing or withholding response to the cue to investigate the relative contributions of response and attention components to IOR. A condition with bilateral display of the cue is also chosen as a control condition, and eight different SOAs between 1,000 and 2,750 ms are tested. Compared to the control condition, response delay to the target at a cued position is eliminated by responding to the cue, and a response advantage to the target at an uncued position is not affected by responding to the cue. Furthermore, both response delay at a cued position and response advantage at an uncued position decrease with SOA in the time window tested in these experiments. The results reported here indicate a dominant response inhibition at a cued position and a primary attentional allocation at an uncued position for IOR. Nonsignificant perceptual/attentional suppression at a cued position is argued to be a benefit for visual detection in a changing world.

Measuring Latinos' perceptions of depression: a confirmatory factor analysis of the Illness Perception Questionnaire

This study examined the psychometric properties of the Revised Illness Perception Questionnaire adapted for a clinical sample of low-income Latinos suffering from depression. Participants (N = 339) were recruited from public primary care centers. Their average age was 49.73 years and the majority was foreign born females of either Mexican or Central American descent. Confirmatory factor analysis was used to test the factor structure of this measure. Construct and discriminant validity and internal consistency were evaluated. After the elimination of three items because of low factor loadings (< .40) and the specification of seven error covariances, a revised model composed of 24 items had adequate goodness-of-fit indices and factor loadings, supporting construct validity. Each of the subscales reported satisfactory internal consistency. Intercorrelations between the 5 illness perception factors provided initial support for the discriminant validity of these factors in the context of depression. The establishment of the psychometric properties of this adapted measure will pave the way for future studies examining the role illness perceptions play in the help seeking and management of depression among Latinos.     

舒芬太尼与芬太尼复合罗哌卡因用于小儿术后镇痛效果比较研究

为了观察舒芬太尼或芬太尼复合罗哌卡因用于小儿术后镇痛的效果及其不良反应,选择ASAⅠ-Ⅱ级行择期下腹部手术的小儿50例,随机分为两组,各25例,术后分别使用0．5μg·m^-1舒芬太尼或2μg·ml^-1芬太尼复合0．1％罗哌卡因行硬膜外病人自控镇痛,观察术后24h镇痛效果及其不反应。结果显示,舒芬太尼组术后24h静态和活动时镇痛效果优于芬太尼组（P〈0．05）,恶心、呕吐发生率低,程度轻（P〈0．05）。因此,舒芬太尼复合罗哌卡因可安全用于小儿下腹部术后镇痛,效果优于芬太尼复合罗哌卡因。     

盐酸戊乙奎醚对输尿管痉挛的预防作用

为了评价盐酸戊乙奎醚对输尿管镜手术中输尿管痉挛的预防作用,将60例拟行经尿道输尿管镜手术的患者随机分为两组,试验组和对照组,每组30例。两组患者均接受硬膜外阻滞,试验组于术前给予盐酸戊乙奎醚0.02mg／kg静脉注射,对照组则接受等量的生理盐水注射。记录术中输尿管痉挛的发生情况,外科医生对手术条件的评分以及术后患者的口干情况。结果显示,试验组输尿管痉挛发生率明显低于对照组,外科医生评分则高于对照组,但术后试验组患者的口干较为明显。提示盐酸戊乙奎醚能够预防输尿管镜手术中输尿管痉挛的发生。
