企业中的上级信任：作为一种行动意愿

组织信任已成为管理学领域的热点研究议题, 虽然研究者开发了多种信任测量工具, 但多数信任测量工具与当前主导的组织信任定义不一致, 缺乏针对意愿的信任测量, 更没有研究探讨不同形态信任之间的关系及相应测量工具的适用范围。本研究以上级信任为切入点, 试图回答上述问题。研究1将信任视为一种行动意愿, 基于信任行为理论框架和开放性问卷结果, 开发了包含6个题目、“依赖”和“表露”两个维度的《企业员工对直接上级信任问卷》。研究2以553名企业员工为被试, 通过潜变量路径分析考察了不同形态信任之间的关系。结果显示：信任(意愿)受认知和情绪因素的共同影响; 可信度在信任基础和信任(意愿)间起部分中介作用; 信任(意愿)在可信度和工作满意的关系中起完全中介作用; 作为意愿的信任, 相对于信任基础(认知和情感信任)和可信度, 与信任结果变量(工作满意)关系最近, 能更直接、有效地测量信任水平。     

上司不当督导与下属绩效:反馈寻求行为和学习目标定向的作用

本研究从下属反馈管理行为的视角来探索领导与下属的社会交换过程.具体为探讨下属的反馈寻求行为在上司不当督导与下属绩效之间的中介作用,下属的学习目标定向对上述过程中的调节作用.通过问卷法获得306名下属与上司的对偶数据,基于层级回归和Bootstrap分析的结果表明:上司不当督导不仅直接影响下属的绩效,还能通过抑制下属的反馈寻求行为间接地影响员工的绩效;下属的学习目标定向调节着上司不当督导与下属的反馈寻求行为的关系,当下属的学习目标定向越低,上司不当督导对反馈寻求行为的抑制作用更加明显.     

基于信任修复归因模型的医患信任修复研究

医患信任是建立良好医患关系的基础,对维护医师的执业环境、构建和谐医患关系具有重要意义.基于信任修复归因模型,从能力、善心、正直三个方面对医患信任缺失的原因进行分析,并对每个层面的原因源、稳定性和可控性进行深层次的研究.在此基础上,系统地提出修复医患信任的对策措施.     

潜在锚定效应的加工机制初探

潜在锚定效应指的是阈限下的启动锚定数字导致的锚定效应现象.本研究探讨了潜在锚定效应的产生机制.采用2(潜在锚类型:高锚vs低锚)×2(词汇类型:夏天vs冬天)混合设计.结果发现,在潜在高锚情况下,夏天词汇的反应时(M=745.50)显著快于冬天词汇的反应时;在潜在低锚情况下,冬天词汇的反应时(M=697.47)显著快于夏天词汇的反应时.即被试对与启动锚定数字信息一致的词汇判断的反应时比不一致的更快.研究结果表明,潜在锚定效应的产生是由于锚定数字内部命题属性被激活导致的.     

大学生信任倾向对社会适应的影响

本研究通过对129名大学生的信任倾向和社会适应的研究,考察了大学生的信任倾向对社会适应的影响。研究结果显示,信任倾向与社会适应的各个指标之间显著相关,即信任倾向越高,个体的人际适应、自我适应与情绪适应就越好。而且信任倾向能够直接预测自我适应,并通过自我适应的中介间接影响人际适应和情绪适应。     

Information Related to Prenatal Genetic Counseling: Interpretation by Adolescents, Effects on Risk Perception and Ethical Implications

Being raised in the genomic era may not only increase knowledge of available genetic testing but may also have an impact on how genetic information is perceived. However, little is known about how current adolescents react to the language commonly used by health care professionals providing prenatal counseling. In addition, as risk communication is related to numbers and figures, having different educational backgrounds may be associated with variability in risk perceptions. In order to investigate these issues, a previously developed questionnaire studying different ways of being told about hypothetical anomalies in a baby and corresponding risks (Abramsky and Fletcher Prenatal Diagnosis 22(13):1188-1194, 2002) was administered to high-school students in Sweden. A total of 344 questionnaires were completed by students belonging to a natural science or a social science program. The data show that teenage participants found technical jargon and words such as rare and abnormal more worrying than the presented comparison terms. Negative framing effects and perception differences related to numeric risk formats were also present. Additionally, participants' gender and educational program did not seem to have an effect on risk assessment. In addition to reporting the questionnaire results, we discuss the ethical implications of the data based on the norm of non-directiveness and make some recommendations for practice. In general, genetic counselors should be aware that the language used within clinical services can be influential on this group of upcoming counselees.     

Dimensionality of the hospital anxiety and depression scale (HADS) in cardiac patients: comparison of Mokken scale analysis and factor analysis

The hospital anxiety and depression scale (HADS) measures anxiety and depressive symptoms and is widely used in clinical and nonclinical populations. However, there is some debate about the number of dimensions represented by the HADS. In a sample of 534 Dutch cardiac patients, this study examined (a) the dimensionality of the HADS using Mokken scale analysis and factor analysis and (b) the scale properties of the HADS. Mokken scale analysis and factor analysis suggested that three dimensions adequately capture the structure of the HADS. Of the three corresponding scales, two scales of five items each were found to be structurally sound and reliable. These scales covered the two key attributes of anxiety and (anhedonic) depression. The findings suggest that the HADS may be reduced to a 10-item questionnaire comprising two 5-item scales measuring anxiety and depressive symptoms.     

Offline consolidation of memory varies with time in slow wave sleep and can be accelerated by cuing memory reactivations

Memory representations are reactivated during slow-wave sleep (SWS) after learning, and these reactivations cause a beneficial effect of sleep for memory consolidation. Memory reactivations can also be externally triggered during sleep by associated cues which enhance the sleep-dependent memory consolidation process. Here, we compared in humans the influence of sleep periods (i) of 40min and (ii) of 90min without externally triggered reactivations and (iii) of externally triggered reactivations by an associated odor cue during a 40-min sleep period on the consolidation of previously learned hippocampus-dependent visuo-spatial memories. We show that external reactivation by an odor cue during the 40-min sleep period enhanced memory stability to the same extent as 90min of sleep without odor reactivation. In contrast, 40min of sleep without external reactivations were not sufficient to benefit memory. In the 90-min sleep condition, memory enhancements were associated with time spent in SWS and were independent of the presence or absence of REM sleep. These results suggest that the efficacy of hippocampus-dependent memory consolidation depends on the duration of sleep and particularly SWS. External reactivation cues can accelerate the consolidation process even during shorter sleep episodes.     

Screening for ADHD in an adult social phobia sample

Objective: Recent studies have suggested a link between a primary anxiety disorder and ADHD. Method: A total of 39 participants with a primary diagnosis of social phobia were compared with 178 patients with ADHD and 88 patients with other psychiatric disorders on measures for childhood and adult ADHD (the Wender Utah Rating Scale and the Adult ADHD Self-Report Scale). Results: Childhood symptoms of ADHD were reported by 7.8% of the social phobia participants, and 5.1% scored within the range of adult ADHD. The social phobia group reported significantly fewer ADHD symptoms than both of the comparison groups, who frequently reported social anxiety. Conclusion: Participants with social phobia recruited from the general population are less likely to suffer from ADHD. In contrast, patients with ADHD and patients with other psychiatric disorders appear to be likely to suffer from social anxiety.
