两种估计多维测验合成信度置信区间方法比较

有两种方法可以估计多维测验合成信度的置信区间：Bootstrap法和Delta法.本文用模拟研究比较这两种方法,结果发现,Delta法与Bootstrap法得到结果的差异很小.因为Bootstrap法得到的是实证结果,通常被认为是真值的反映,而Delta法比Bootstrap法简单得多,所以可以用Delta法估计合成信度的置信区间.举例演示如何计算多维测验的合成信度以及用Delta法计算其置信区间.     

听觉诱发表象的眼动机制

视觉心理表象是一种基于过去经验的自上而下的加工过程,它是信息表征的一种形式.以往的研究主要采用视觉来诱发表象,但是这很难排除视觉后像的干扰,而且与表象“自上而下”的加工过程不一致.听觉诱发表象很好地解决了视觉后像的干扰问题,也更吻合表象“自上而下”的加工过程,因为被试产生的表象是基于自己过去的经验,从自身出发,主动加工的结果.采用实验法,考察通过听觉通道诱发表象眼动的情况,使用眼动仪记录被试的眼动轨迹.结果发现：（1）不管是运动还是静止的物体,都能诱发表象,在表象时存在眼动行为.（2）运动的物体诱发眼动的程度更大.（3）眼动影响表象的建构,在表象建构中起机能性作用.     

The Flexible Correction Model: Bias Correction Guided by Naïve Theories of Bias

Psychological researchers have examined a broad array of biases and shortcomings of social perceivers. Less attention has been paid to how people react when they become concerned about the possibility of bias and attempt to correct or overcome the potential for bias. An early approach was to think of bias correction as “subtracting” information or reactions that are identified as coming from the biasing factor instead of the target. An alternative approach is to conceptualize bias correction as guided by social perceivers' naïve theories or perceptions of the bias at work. The subtraction theories were designed to deal with the assimilative biases typical of early priming experiments, but theory‐based corrections can readily deal with either assimilative or contrastive biases. We describe both types of correction theories, with a focus on the empirical support for theory‐based correction (and especially for the Flexible Correction Model). We also identify future directions for research on theory‐based correction.     

Real men are made,not born! Incidental exposure to energy drinks may promote men's tolerance of physical pain

The energy drink market has grown exponentially since the debut of Red Bull. Advertising of energy drinks tends to reinforce an emphasis on masculine identification. However, no previous study has addressed the symbolic effect of energy drinks on pain tolerance, that is, a particular masculine characteristic. We conducted a priming‐based experiment to show that energy drink primes elevated men's pain tolerance. Induced conformity to masculinity norms mediated the priming effect of energy drinks on pain tolerance. These findings suggest that mere reminders of masculinity‐related products can lead men to behave accordingly in seemingly irrelevant domains (i.e., pain tolerance). Besides distraction and placebo treatment, the connection between a symbolic masculinity prime and greater tolerance of pain may shed lights on an alternative route for pain control.     

Prevalence of depressive symptoms and its correlates among medical students in China: a national survey in 33 universities

We conducted a national survey among medical students in China to estimate the prevalence of depressive symptoms and explore associated risk factors based on an established questionnaire composed of demographic information, life events in the past four weeks before survey, and the validated Chinese version of the 21-item Beck’s Depression Inventory (BDI). The mean age of enrolled 9010 students was 20.7 (standard deviation: 1.6) years. BDI scores indicated that 19.9% had depressive symptoms based on the cut-off score of 14. Socioeconomic factors and student characteristics such as male sex, low monthly income per capita, father’s poor education background, and higher year of study were associated with higher prevalence of depressive symptoms among medical students. Students who studied in comprehensive universities were more likely to have depressive symptoms compared with those from medical universities. Habitual smoking and alcohol drinking, sleep deprivation, and hospitalization or medication for one week or more in the last four weeks also predisposed students to higher risk of depressive symptoms. Our results indicate that depressive symptoms are becoming a highly prevalent health problem among Chinese medical students. Primary and secondary prevention should be prioritized to tackle this issue based on potential risk factors.     

阅读进度反馈信息对工作同盟和咨询效果的影响

进度反馈指将对当事人的标准化测量结果和解释反馈给咨询师的干预, 其目的在于矫正咨询师对咨询效果主观评估的偏差, 提高咨询效果。考虑到咨询师和当事人“面对面”的标准反馈程序不符合我国社会文化习惯, 采用多层结构方程模型, 分析了自然情境下非“面对面”的进度反馈对工作同盟和咨询效果的影响。结果发现, 在组间水平, 反馈组的工作同盟质量更好; 在组内水平, 工作同盟与症状是相互预测的关系。在结案时, 反馈组在抑郁症状和咨询的有帮助性上效果更好。结论是进度反馈对工作同盟和咨询效果有积极影响。研究从工作同盟和中国人的关系角度拓展了对进度反馈作用机制的认识, 为进度反馈的应用提供了基于实践干预有效的证据。     

群体共同经历影响不公平感知

以往研究考察了不公平经历如何影响个体的认知、情绪及行为。然而, 这些研究着重于考察个体“独自经历”不公平的现象, 而尚未有研究考察, 当个体与他人以群体身份共同经历不公平时, 不公平经历对个体的影响。3项实验采用改编的三人最后通牒博弈任务考察“群体共同经历”不公平如何影响个体的不公平感知。研究结果表明, 无论是通过“共同命运” (实验1)、轮流为群体做决策(实验2), 还是招募成对朋友(实验3)来操纵或凸显群体身份, 群体共同经历不公平, 相比独自经历不公平, 均显著降低(而非提升)了被试的不公平感知。研究结果对于社会及组织管理具有借鉴意义。     

大脑电刺激在听觉语言加工研究中的应用

大脑电刺激是历史悠久但近年来才广泛应用在人类被试上的实验技术。通过对颅内刺激位点进行电刺激, 并分析引发的暂时性行为功能变化和记录位点的电位活动, 大脑电刺激技术可以揭示认知加工过程中脑区内的功能作用与脑区间的有效连接。通过对听觉语言加工过程相关的丘脑、听觉皮层、高级语言皮层进行电刺激, 现有研究发现了各个脑区的不同功能特点以及不同脑区间的信息传递机制, 为进一步探索听觉语言加工的神经机制提供了新的视角。     

父母行为控制、心理控制与高中生消极社会适应的关系：人际自立和校园排斥的序列中介作用

基于自我决定理论和人与环境互动理论,研究考察了父母行为控制、心理控制与高中生消极社会适应的关系,以及人际自立与校园排斥的中介效应。采用父母控制问卷、青少年人际自立量表、青少年校园排斥问卷、消极社会适应问卷对辽宁省3所中学的1209名高中生进行施测。结果发现:(1)父母行为控制对高中生消极社会适应无明显预测作用,心理控制对消极社会适应具有正向预测作用;(2)人际自立和校园排斥在父母控制与消极社会适应之间发挥中介作用。具体而言,父母行为控制只能通过人际自立的单独作用以及人际自立与校园排斥的序列中介作用预测高中生消极社会适应;父母心理控制既能直接预测消极社会适应,还能分别通过人际自立和校园排斥的单独作用,以及人际自立与校园排斥的序列中介作用预测高中生消极社会适应。研究最终梳理出一条“父母教养→人格发展→人际反馈→适应结果”的理论作用机制。     

快慢读者利用语境信息的差异：加工深度的作用

通过主题扫描和阅读理解两种加工深度不同的任务,考察快慢读者预测性效应差异的来源及加工深度在其中发挥的作用。被试在两种任务情境下阅读分别包含高低预测性目标词的96个句子框架,记录其眼动轨迹。结果显示：预测性效应仅在阅读理解任务中出现,快速读者在早期眼动指标上就表现出了预测性效应,慢速读者在晚期眼动指标上才表现出预测性效应。结果表明：加工深度调节快慢读者预测性效应的大小;在自然阅读情境下快慢读者的预测性效应表现符合预测编码框架假设。
