Agency, subjective time, and other minds

Intentional binding refers to a temporal attraction in the perceived times of actions and effects. So far, it has solely been investigated using judgments of the perceived time of actions or their effects. The authors report 3 experiments using an alternative method: the estimation of a time interval between a voluntary action and its subsequent effect. Interval estimates were obtained for intervals bounded by different kinds of actions and effects: The actions were either performed by the participants themselves or by the experimenter. The effects, in turn, were movements either applied to the body of the participant or to the experimenter. First, the results validated interval estimation as a method for exploring action awareness. Second, intentional binding was stronger for self-generated compared with observed actions, indicating that private information about the action contributes to action awareness. In contrast, intentional binding did not depend on whether a somatic effect was applied to the participant's or to another person's body. Third, for self-generated actions, external events gave rise to a stronger intentional binding than did somatic effects. This finding indicates that intentional binding especially links actions with their consequences in the external world.     

Sexual objectification pushes women away: The role of decreased likability

The present investigation examined the effect of sexual objectification on women's intention to affiliate with men. We predicted that women would perceive an objectifier as less likable following sexual objectification and thus would distance themselves from the perpetrator. Study 1 found that objectification led female participants to perceive their male partner as less likable and to be less willing to affiliate with the partner. Study 2 replicated Study 1 in a concurrent interpersonal interaction and extended these effects to a man having a similar background with the perpetrator. Study 3 showed that power moderated the effect of sexual objectification on women's interaction intention such that only women with equal or low power (as compared to the objectifier) decreased their affiliation intention toward the objectifier, whereas high‐power women did not show this effect. Implications of these findings were discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

The Giessen virtual environment laboratory: human wayfinding and landmark salience

In our virtual environment laboratory, we focus on different topics in human spatial cognition with projects on landmark salience, route knowledge, and survey knowledge. Within this laboratory note, we provide an overview of previous, current, and future work with our virtual environment Squareland.     

企业伦理的德性主义进路及其条件——以所罗门的亚里士多德方式为例

理解企业伦理的德性主义进路不可或缺。美国当代著名经济伦理学家罗伯特·C．所罗门成功地将亚里士多德德性论引入企业伦理学,为人们把握企业伦理提供了一条德性主义的诠释进路。而亚里士多德德性论强调实践、团体、人对幸福的追求和追求卓越等也为企业伦理的德性主义进路提供了思想资源。而美德自身也能够使人们正确地理解商业和商业伦理、使经济交易成为可能、使经济的运行更为成功。但德性主义进路不是没有条件的,它需要个体或企业具有良好的道德价值观念和良好的判断力,也需要规范伦理与之匹配,以及一个尊重美德的社会环境和相关的制度安排。     

领导风格与员工创新绩效关系的元分析：基于自我决定视角

领导对员工创新起到重要作用。什么样的领导风格与员工创新相关更高?实际研究中存在一定争议。为了回答这个问题,基于自我决定理论,我们提出一个理论框架,来解释不同领导风格与员工创新相关系数的差异。我们使用元分析汇集432篇独立的实证研究的证据(中文研究229篇,英文研究203篇,样本总量达161599),来检验我们的假设。研究发现：(1)交易型领导、伦理型领导、变革型领导、服务型领导、领导-成员交换、授权型领导、包容型领导及真实型领导与员工创新绩效之间均存在显著的正相关,且相关递增;(2)个人主义、绩效评价方式、数据收集时间点、领导风格测量方式、创新测量方式以及发表语言部分调节领导风格和员工创新绩效的关系。研究结果符合理论预测,研究促进自我决定理论的发展。更为重要的是,研究结论为管理者提供重要的实践意义,即使用合适的领导风格进而促进员工创新。     

Psychometric evaluation and experimental validation of the statistics anxiety rating scale

The Statistics Anxiety Rating Scale (STARS) was adapted into German to examine its psychometric properties (n = 400). Two validation studies (n = 66, n = 96) were conducted to examine its criterion-related validity. The psychometric properties of the questionnaire were very similar to those previously reported for the original English version in various countries and other language versions. Confirmatory factor analysis indicated 2 second-order factors: One was more closely related to anxiety and the other was more closely related to negative attitudes toward statistics. Predictive validity of the STARS was shown both in an experimental exam-like situation in the laboratory and during a real examination situation. Taken together, the findings indicate that statistics anxiety as assessed by the STARS is a useful construct that is more than just an expression of a more general disposition to anxiety.     

随机临床试验中伦理问题的探讨

随着我国的药物临床试验过程逐渐完善,药物临床试验水平不断提高,但伦理学方面并不十分完善.临床研究者和受试者应该明确自己的权益和义务,并在药物随机临床试验中,使受试者的权益得到更好的保护.本文论述并总结了药物临床试验中出现的问题,并提出了改进措施.     

记忆编码策略对心境一致性记忆的调节作用

情绪对记忆的影响会受记忆编码策略的调节。本研究通过2个实验探讨编码策略对心境一致性记忆的调节作用。实验1和实验2均采用2（编码策略：提取练习策略、重复学习策略）×2（词性：消极词、中性词）的实验设计,分别探讨了不同记忆编码策略对普通大学生（实验1）和非临床抑郁大学生（实验2）心境一致性记忆的影响。结果发现：无论是被成功诱导出抑郁情绪的普通大学生,还是非临床抑郁倾向大学生,使用重复学习策略时回忆出的消极词均显著多于中性词,表现出显著的心境一致性记忆,而使用提取练习策略时回忆出的消极词和中性词没有显著性差异,未表现出心境一致性记忆。实验结果表明,记忆编码策略对心境一致性记忆具有调节作用,提取练习策略能够抑制心境一致性记忆。研究结果指明了心境一致性记忆的边界条件,并对非临床抑郁个体的学习与记忆具有重要的启示。     

鼻咽癌患者调强放疗与常规放疗毒副反应对比研究

探讨鼻咽癌患者常规放射治疗(CRT)与调强放射治疗(IMRT)的疗效和常见副反应,为鼻咽癌患者放疗方法选择提供科学依据.选取2010年11月至2013年5月行CRT和IMRT的初治鼻咽癌患者共56例,比较IMRT和CRT组的急性毒性反应和晚期放射性损伤.IMRT组和CRT组在局部复发和远处转移方面,两组差异无统计学意义(P＞0.05),常见急性毒性反应如:口干、吞咽疼痛、听力下降、皮肤和黏膜反应的发生率CRT组高于IMRT组,差异有统计学意义(P＜0.05);晚期损伤中口干、皮肤纤维化发生、吞咽困难等方面CRT组高于IMRT组,差异有统计学意义(P＜0.05),而在视力下降和脑损伤的发生等方面,两组差异无统计学意义(P＞0.05).与CRT技术相比较,IMRT技术能够有效减少急性毒副反应和晚期损伤的发生率,可提高患者生活质量(QOL).     

Analysis of individual variations in the classical horizontal-vertical illusion

In the horizontal-vertical illusion (HVI), the length of the vertical line is overestimated, whereas in the bisection illusion (BI), the horizontal bisecting line is expected to be overestimated. Here, only half of our 22 observers showed the expected BI, whereas the other half underestimated the bisecting line. Observers also differed in their judgments of the strength of the HVI: The HVI was stronger for observers showing the classical bisection effect, and weaker or absent for those underestimating the bisecting line. To account for these results, we used a linear model to individually estimate the strength of two putative factors underlying both illusions. Whereas the strength of the HVI and BI were highly correlated, the estimated factors were uncorrelated. Therefore, in two control experiments, we then measured the pure horizontal-vertical (pHVI) and bisection (pBI) illusions. A significant correlation between the estimated factors and the measured illusion variants was found. Results were robust against variations of contrast, repetitive presentations, and choice of adjusted line. Thus, the classical HVI as an additive combination of two independent factors was confirmed, but we found considerable interindividual variations in the strength of the illusions. The results stress the importance of analyzing individual data rather than taking sample means for understanding these illusions.
