单侧化准备电位启始时间点的测算:刀切法*

刀切法是统计学家Quenouille提出的一种参数估计方法,由Miller等在1998年首次将刀切法应用在单侧化准备电位(LRP)启始时间点(onset)的测量中。相对于以往单个被试法而言,它是较新的一种统计方法。本文综述了刀切法的统计原理和基本使用过程,并和单个被试法进行了差异比较,最后对这一方法的发展趋势做了展望。     

Experiencing Racial Humor with Outgroups: A Psychophysiological Examination of Co-Viewing Effects

Research on co-viewing (or group viewing) is scarce. Yet, co-viewing has important implications for the viewers’ entertainment experience and the way viewers respond to and evaluate entertainment—especially those with controversial messages. The present study investigated responses to racial humor content among racial in-group and out-group viewing contexts. Specifically, the study examined the extent to which Blacks and Whites would experience discomfort when viewing racial slurs in comedies with in-group compared to out-group members. Employing real-time psychophysiological data and multilevel time series models, the study found a significant increase in emotional arousal (indicated by SCRs) and distraction (indicated by RSA) among Blacks in the context of out-group viewing compared to in-group viewing, but not for Whites. Implications of findings are discussed.     

The influence of visual mental imagery size on metamemory accuracy in judgment of learning

Many studies have found the font size of to-be-remembered words has a significant influence on judgments of learning (JOLs). However, few studies have investigated whether JOLs are affected by the mental imagery size of to-be-remembered words, even when the font sizes themselves are kept identical in study materials. This study investigated whether the visual mental imagery size influences the participants’ JOLs and what the underlying mechanisms are. In Experiments 1 and 2, participants learned words with identical font sizes, mentally generated large or small imageries and then made JOLs. We found that JOLs under the large imagery condition were significantly higher than those under the small imagery condition, but actual recall performance exhibited no significant difference. In Experiment 3, participants pressed a button immediately after mental imagery generation and showed that it took significantly longer to generate large imageries than to generate small imageries, and the difference in JOLs between two conditions was no longer significant. In Experiment 4, we used a questionnaire to investigate the contribution of beliefs and found that participants believed large imageries were easier to remember. These findings indicate that imagery size has a significant impact on JOLs, in which beliefs may play a leading role.     

注意焦点转换中的返回抑制与更新过程有关

从认知过程的角度考察注意焦点转换中的返回抑制产生的原因。两个实验要求被试为三个图形分别保持一个数字。实验1设置两种任务:"提取且更新任务"要求被试每次提取一个图形的数字,并对数字进行更新;"提取任务"要求被试只需提取图形的数字,而无需对数字进行更新。实验2设置"更新任务",要求被试只需更新图形的数字,而无需对数字进行提取。实验同时设置抑制转换类型和控制转换类型,以考察返回抑制现象。结果表明,在"提取且更新任务"和"更新任务"中存在返回抑制现象,而在"提取任务"中未发现返回抑制现象。这说明,注意焦点转换中的返回抑制现象与更新过程有关。     

A survival analysis of the impact of boundary crossings on managerial career advancement up to midcareer

Although managers and professionals still compete in a career tournament for advancement and pay, the career boundaries that they cross in order to compete have changed. Traditionally, such individuals came up through the ranks within the same company by specializing in one functional area and changing, as needed, the geographic location of work in order to advance their careers. However, in the current era of less constrained, boundary-crossing careers, they are more apt to cross several boundaries, including functional, organizational, geographic, and family, as they pursue career opportunities. Using survival analysis with data from the career histories of 760 managers and professionals who collectively made 3917 moves up to midcareer, we examined the impact of the rate of crossing each boundary on the subsequent likelihood of advancement. In addition, over this span of career, we examined the extent to which more rapid advancement contributed to the rate of growth in annual salary. Our findings suggest that crossing functional, organizational, and geographic boundaries more often significantly increased the likelihood of advancement, whereas the duration of family boundary crossings had a negative impact. Moreover, as expected, advancement had a long-term impact on salary growth.     

Factors for radical creativity, incremental creativity, and routine, noncreative performance

This study extends theory and research by differentiating between routine, noncreative performance and 2 distinct types of creativity: radical and incremental. We also use a sensemaking perspective to examine the interplay of social and personal factors that may influence a person's engagement in a certain level of creative action versus routine, noncreative work. Results demonstrate that willingness to take risks, resources for creativity, and career commitment are associated primarily with radical creativity; that the presence of creative coworkers and organizational identification are associated with incremental creativity; and that conformity and organizational identification are linked with routine performance. Theoretical and managerial implications are discussed.     

How School Counselors Can Help Prevent Online Victimization

Although the Internet is a beneficial tool, some youth are at risk for being victimized by Internet predators. School counselors are in a unique position to assist in efforts to prevent online victimizations because of their continual interaction with students, parents, and other school faculty. This article provides school counselors with information about youth Internet use; risk factors associated with online victimizations; and recommendations to assist youth, parents, and families in improving Internet safety practices.

采用问卷调查法,以330名企业员工为调查对象,使用层次回归分析探讨了员工资质过高感知对其创新行为和工作满意度的影响机制。结果表明:(1)员工资质过高感知对其创新行为和工作满意意度具有显著的负向预测作用;(2)心理契约违背在资质过高感知对员工工作满意度的影响过程中起完全中介作用,在资质过高感知对员工创新行为的影响过程中部分中介作用;(3)心理授权在员工资质过高感知通过心理契约违背影响员工工作满意度的过程中起调节作用。     

小学生领导力萌芽与发展的实证研究

摘 要 本研究以四年级学生为研究对象,通过话语分析,探究了八个无领导小组八次讨论过程中领导力的萌芽状况及其影响因素。结果发现,小学生可自发出现领导力行为,但只有两个小组会涌现出明显的领导者,并表现为独立领导和协同领导两种不同模式。对学生和教师行为的综合分析显示,学生领导力的形成与教师示范、反馈及同伴互动存在密切关系,这对学生领导力的培养具有重要的启示意义。     

Older children's misunderstanding of uncertain belief after passing the false belief test

A four-location belief task was designed to examine children's understanding of another's uncertain belief after passing a false belief (FB) task. In Experiment 1, after passing the FB task, participants were asked what a puppet would do after he failed to find his toy at the falsely believed location. Most 4-year-olds and half of 6-year-olds children who passed the FB test showed difficulty in handling uncertain belief; answering that the puppet would then look for his toy at the current (moved-to) location. Eight-year-old children and adults all recognized that the puppet would look for the toy everywhere, or at random. In Experiment 2, 4- and 6-year-olds were presented two other search tasks; it was shown that preschoolers could use search strategies to solve a similar search problem when FB was not involved. This new aspect of post-FB understanding can be interpreted in terms of limited understanding of uncertainty in a less-knowledgeable individual and of limited ability to infer the consequences of belief-disconfirmation.
