Exploring rates of transgender individuals and mental health concerns in an online sample

Background: Prevalence estimates of adults identifying as transgender are scarce, particularly in the United States. Method: The current study endeavored to estimate the prevalence of individuals identifying as transgender in a large online sample of adult U.S. residents (n = 6,727) and compare the prevalence of common mental health disorders (depression, anxiety, attention-deficit/hyperactivity disorder) and the age of onset for individuals identifying as men or women versus those identifying as transgender. Results: The prevalence estimate of individuals identifying as transgender was 0.8%. Individuals identifying as transgender were significantly more likely than individuals identifying as men or women to report having had a single diagnosis or co-occurring diagnoses for all three disorders examined. Additionally, transgender individuals were more likely than individuals identifying as men or women to receive a diagnosis of anxiety or depression at a younger age. Conclusion: Given the prevalence of transgender individuals and the associations with common mental health conditions, clinicians must be informed and competent to care for their clinical needs. This study introduces online crowdsourcing resources as a potentially fruitful option for reaching and researching gender diversity.     

中国情境下团队伦理决策的过程机制及影响因素

尽管绝大多数商业伦理决策都是由团队而非个人所做出的,但目前对团队伦理决策的研究还很少,尤其缺乏基于理论的深入研究。在前人研究的基础上,借鉴个体伦理决策和团队决策方面的研究成果,结合中国文化强调反省、中庸、威权领导等特点,我们对团队伦理决策的过程机制及影响因素的作用模式展开理论驱动的深入研究。具体来讲,将综合利用多种方法来进行两个方面的4项子研究。在团队伦理决策的过程机制方面,拟开展团队伦理决策的过程机制模型构建研究,然后聚焦于团队伦理决策和个体伦理决策的核心区别,展开基于社会决策图式理论的团队伦理决策观点整合机制研究;在团队伦理决策的影响因素作用模式方面,拟从成员和领导两个方面来进行:基于信息加工和团队冲突的成员多样性对团队伦理决策的影响机制研究,基于信息取样模型的领导特征对团队伦理决策的影响机制研究。     

工作中心度的作用及其与领导行为的关系研究

本研究在理论分析的基础上,探讨了工作中心度对职业生涯规划的作用,并进一步分析了以工作中心度为因变变量(contingent variable)的领导行为的有效性。通过问卷调查法对233位企业员工进行测量。结果发现:工作中心度高的员工对于他们的职业生涯会有更好的规划;应根据员工不同程度的工作中心度采取不同的领导行为,后者有利于员工更好地规划自己的职业生涯。     

A phase transition model for the speed-accuracy trade-off in response time experiments

Most models of response time (RT) in elementary cognitive tasks implicitly assume that the speed-accuracy trade-off is continuous: When payoffs or instructions gradually increase the level of speed stress, people are assumed to gradually sacrifice response accuracy in exchange for gradual increases in response speed. This trade-off presumably operates over the entire range from accurate but slow responding to fast but chance-level responding (i.e., guessing). In this article, we challenge the assumption of continuity and propose a phase transition model for RTs and accuracy. Analogous to the fast guess model (Ollman, 1966), our model postulates two modes of processing: a guess mode and a stimulus-controlled mode. From catastrophe theory, we derive two important predictions that allow us to test our model against the fast guess model and against the popular class of sequential sampling models. The first prediction--hysteresis in the transitions between guessing and stimulus-controlled behavior--was confirmed in an experiment that gradually changed the reward for speed versus accuracy. The second prediction--bimodal RT distributions--was confirmed in an experiment that required participants to respond in a way that is intermediate between guessing and accurate responding.     

抽样组合中元素数量对青少年组合成绩的影响

先前抽样组合问题研究表明达到形式运算阶段青少年的抽样组合思维成绩表现并不一致,作者分析猜想可能的原因是组合元素数量增加会降低被试的抽样组合成绩。现在实验考察高中一年级学生的抽样组合思维能力,以组合问题中的总体元素数量和样本元素数量为自变量,设置了五选三、七选三和七选四的三种抽样组合问题条件。实验结果发现,随着总体元素数量和样本元素数量的增加,被试的组合成绩明显下降。这表明,青少年的抽样组合思维能力虽已获得,但随组合元素数量增加而表现出倒退,并没达到成熟的一般性;其发展水平可能存在初级水平到高级水平的区分。     

Sampling in research on interpersonal aggression

The aim of this study was to investigate the usefulness of convenience samples in research on interpersonal aggression among adults. It was hypothesised that convenience sampled targets of aggression differs from targets in general with regards to both demographic characteristics and degree of aggression exposed to. A convenience sample comprising support-seeking targets of workplace bullying was compared with a representative sample of Norwegian targets of bullying. The results showed that the two samples differed significantly on all demographic variables investigated, except gender. A far higher percentage of the convenience sample had blown the whistle on illegal, immoral or illegitimate practice at their workplace, whereas they also reported significantly more frequent and more intense exposure to aggression. The findings confirm that convenience samples have low external validity when generalising to the general population. Such samples should therefore mainly be used to investigate tendencies in, and the phenomenology of, interpersonal aggression, in studies where generalisability is not the principal objective.     

日常经验研究：一种独具特色的研究方法

日常经验研究是一种通过研究日常生活中各种事件发生时人们的瞬时感受而在自发、自然的情景中对人的心理现象、过程进行探索的方法。其目的是通过获得关于个人日常生活中某些特定事件或特定时刻的详细描述,来提取有关思维、情绪、行为的持久性、周期性、变化以及时间结构等方面的信息,并确定上述因素之间的情境性以及倾向性相关。日常经验研究的价值和意义在于在方法论三角互证原则的指导下,与其他各种方法结合起来,帮助研究者从不同角度理解心理现象及其过程,从而达到最大限度地探索、了解人类心理世界的目的     

项目特征曲线等值的抽样误差

现在,等值越来越受到各考试测验机构及测量学研究人员的重视,特别是项目反应理论等值的优越性更使他们有了信心。然而,很多人却没有注意到被试能力分布形态可能给等值结果带来的影响效果及程度。本研究以项目反应理论两级记分模型的项目参数等值在不同被试能力分布形态下的结果差异作为重点,探讨被试抽样偏差可能给项目特征曲线等值带来的误差问题。研究结果表明,被试能力分布形态会显著地影响项目参数等值的系数,特别地,能力分布的偏态系数与等值方程的截距存在显著的线性相关关系,但能力分布形态的变化对等值方程中斜率的影响并不明显
