Acute psycho-social stress does not disrupt item-method directed forgetting, emotional stimulus content does

It has been shown that stress affects episodic memory in general, but knowledge about stress effects on memory control processes such as directed forgetting is sparse. Whereas in previous studies item-method directed forgetting was found to be altered in post-traumatic stress disorder patients and abolished for highly arousing negative pictorial stimuli in students, no study so far has investigated the effects of experimentally induced psycho-social stress on this task or examined the role of positive picture stimuli. In the present study, 41 participants performed an item-method directed forgetting experiment while being exposed either to a psychosocial laboratory stressor, the Trier Social Stress Test (TSST), or a cognitively challenging but non-stressful control condition. Neutral and positive pictures were presented as stimuli. As predicted, salivary cortisol level as a biological marker of the human stress response increased only in the TSST group. Still, both groups showed directed forgetting. However, emotional content of the employed stimuli affected memory control: Directed forgetting was intact for neutral pictures whereas it was attenuated for positive ones. This attenuation was primarily due to selective rehearsal improving discrimination accuracy for neutral, but not positive, to-be-remembered items. Results suggest that acute experimentally induced stress does not alter item-method directed forgetting while emotional stimulus content does.     

A comparison of impulsivity and sensation seeking in pathological gamblers and skydivers

The aim of this study was to compare pathological gamblers and skydivers in relation to measures of impulsivity and sensation seeking. The Eysenck Impulsivity Scale - Narrow Impulsiveness Subscale and the Arnett Inventory of Sensation Seeking were administered to pathological gamblers (n = 29), skydivers (n = 93), and a control group (n = 43). A two-way multivariate analysis of variance was conducted to explore differences in impulsivity and sensation seeking between the groups and possible group by gender and group by age interaction effects. The significant effects were further investigated using follow-up univariate analysis of variance. The results showed significant main effects of Group, Gender and Age, and a significant Group by Gender interaction effect. The results showed no statistically significant differences in impulsivity between pathological gamblers and skydivers; however, both groups scored higher than the controls. The skydivers scored higher compared to the pathological gamblers and controls on both sensation seeking subscales. Pathological gamblers scored higher than the controls on the subscale Need for Stimulus Intensity, although lower than the controls on the subscale Need for Novelty. We conclude that skydivers and pathological gamblers do not seem to differ in terms of impulsivity, but that the two groups differ in terms of sensation seeking. Skydivers are hence characterized by more sensation seeking compared to pathological gamblers. Skydiving, as opposed to pathological gambling, is not considered a psychiatric disorder, and skydiving may represent a more non-pathological way to fulfill the need for stimulus intensity.     

Outgroup helping as a tool to communicate ingroup warmth

The authors extend previous research on the effects of metastereotype activation on outgroup helping by examining in more detail the role of group impression management motives and by studying direct helping (i.e., helping the outgroup believed to hold a negative view of the ingroup). Data from three experiments provided full support for the communicative nature of direct outgroup helping by demonstrating that outgroup helping in response to a negative metastereotype was predicted by participants' concern for the image of their ingroup, but not by their self-image concerns. Moreover, group image concerns predicted outgroup helping but not ingroup helping and predicted outgroup helping only when a negative metastereotype was activated, compared with a positive metastereotype, or a (negative or positive) autostereotype. The results also ruled out an alternative explanation in terms of denying the self-relevance of the metastereotype.     

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.     

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。

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。     

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.     

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.
