Lapses of intention and performance variability reveal age-related increases in fluctuations of executive control

We examine the hypothesis that the efficiency of executive control processes is less stable over time in older than younger adults. An age-related decrease in the efficiency of executive control should result in an increase in performance variability in task conditions requiring the recruitment of executive control processes and not in task conditions requiring minimal involvement of executive control. Performance variability was similar for younger and older adults in task conditions requiring minimal executive control and greater for older than younger adults in task conditions requiring executive control. These and other data are consistent with the proposal that aging is associated with a decrease in the stability of executive control over time.     

Accountability Forces in Performance Appraisal: Effects of Self-Appraisal Information, Normative Information, and Task Performance

This study investigated the effects of self-appraisal information, normative information, and task performance on performance appraisal ratings. Participants rated a fictitious subordinate's performance on a clerical task (which was either very good or moderately poor) subsequent to receiving self-assessment information (high or low) and normative information (present or absent). Self-appraisals affected performance ratings for poor performers but not for good performers, suggesting that judges are more motivated to please ratees than they are merely to adopt the subordinate's view of their own performance. Furthermore, objective normative information had greater influence than self-appraisals on performance ratings, suggesting that information source credibility has more influence than felt accountability on performance appraisals. Implications of the findings for organizations were discussed.     

Police Officer Performance Under Stress: A Pilot Study on the Effects of Visuo-Motor Behavior Rehearsal

This study examined the effectiveness ofvisuo-motor behavior rehearsal(VMBR) as a method of reducing acute stress and improving police officer performance. Fifty-four recruits were randomly assigned to a treatment and a nontreatment condition prior to undergoing a highly stressful, critical event training scenario involving live fire. A manipulation check showed that participants who received VMBR displayed significantly lower scores on the cognitive state anxiety subscale of the Competitive State Anxiety Inventory-2; somatic state anxiety and self-confidence were unaffected by the VMBR treatment. Most importantly, participants in the VMBR training condition displayed better performance on the critical event scenario, including significantly more assailant hits. The findings are discussed with respect to the four-stage model of stress and human performance of Salas and colleagues.     

Rewarded remembering: dissociations between self-rated motivation and memory performance

People often claim that they perform better in memory performance tasks when they are more motivated. However, past research has shown minimal effects of motivation on memory performance when factors contributing to item-specific biases during encoding and retrieval are taken into account. The purpose of the present study was to examine the generality of this apparent dissociation by using more sensitive measures of experienced motivation and memory performance. Extrinsic motivation was manipulated through competition instructions, and subjective ratings of intrinsic and extrinsic motivation were obtained before and after study instructions. Participants studied a series of words, and memory performance was assessed by content recall (Experiment 1) and source recall (Experiment 2). Both experiments showed dissociation between subjective ratings of extrinsic motivation and actual memory performance, so that competition increased self-rated extrinsic motivation but had no effects on memory performance, including source recall. Inconsistent with most people's expectations, the findings suggest that extrinsic motivation has minimal effects on memory performance.     

Job Insecurity Spillover to Key Account Management: Negative Effects on Performance,Effectiveness, Adaptiveness,and Esprit De Corps

Most of the existing research on outcomes of job insecurity has identified individual-level burdens such as reduced attitudinal attachments toward work and well being. Far fewer studies have examined work-related outcomes that are of substantial concern to organizational success. In this paper, we investigated four new work-related outcomes of job insecurity that are part of the literature on key account management (KAM): customer performance, effectiveness with customers, adaptiveness to changing competitive conditions, and esprit de corps. A total of 353 U.S. based employees participated. The findings of this research suggest that job insecure workers perceive their organizations to be ineffective in delivering on all four KAM outcomes.     

同事评价教师绩效的结构验证性因素分析

考察了教师绩效同事评价结果的因素结构。通过文献回顾、开放式调查、关键事件访谈和理论分析,提出了教师绩效的结构,通过验证性因素分析验证了同事评价教师绩效的结构。发现教师绩效包含6个维度,即职业道德、职务奉献、助人合作、教学效能、教学价值与师生互动,前3个维度组成关系绩效,其余维度组成任务绩效。关系绩效与任务绩效有较高的相关。     

短时作业中警戒绩效影响因素的实验研究:兼用信号检测论分析

本文研究了短时（１小时内）作业中警戒绩效的一些影响因素。实验采用ＥＰ７１０警戒仪,研究了短时作业中时间、信号密度（信噪比）以及信号显著性（占空比）对警戒绩效的影响。使用的方法为信号检测论。因变量指标为辨别力指数ｄ’和判断标准Ｂ。结果发现,作业时间和占空比对警戒绩效没有影响,信噪比对辨别力指数ｄ’有影响但对判断标准Ｂ没有影响。结果提示,在短时作业中,信噪比对警戒绩效起显著作用．     

Integrating Hip‐Hop Culture and Rap Music Into Social Justice Counseling With Black Males

In this article, the author suggests that Hip‐Hop culture and rap music, in particular, can be integrated into individual counseling interactions with Black male clients to discuss the social injustices (e.g., hypercriminalization) they face. Literature examining the history of Hip‐Hop culture and how rap music has been used therapeutically with Black males is presented. The article concludes with a vignette illustrating how Elligan's ( 2000 ) rap therapy framework can help explore experiences Black male clients encounter.     

Case Demonstration of Environmental Cuing and Brief Supervision Monitoring as Performance Management Interventions with Educational Care Providers

Abstract

The present study evaluated two interventions to improve task completion-data recording by two classroom instructors at a school for children and youth with neurodevelopmental disorders. Compared to a baseline phase, intervention through environmental cuing (strategic task scheduling) was ineffective. The addition of brief supervision monitoring (task preview and review) increased task completion-data recording to high levels and the improved performance of the classroom instructors and was sustained one month following the study in the absence of intervention. Social validity assessment documented high approval of and satisfaction with brief supervision monitoring. We discuss these findings with reference to practical and efficient methods of performance management that can be implemented with care providers in educational services settings.     

高职生因果定向与学业表现的关系

为了考察高职生因果定向的特点及因果定向与学生学业表现(学业成绩和专业技能)的关系。该研究以修订的一般因果定向量表为工具,在济南和淄博的三所高职抽取505名学生作为被试进行调查。结果发现:1)修订后的一般因果定向量表具有良好的信效度;2)高职生在因果定向的三个维度上得分差异显著,由高到低依次为自主定向、控制定向和非个人定向;3)自主定向显著正向预测学业表现,控制定向显著负向预测学业表现,而非个人定向对学业表现的预测作用不显著。我国高职生与国外被试的因果定向特点基本一致,说明因果定向具有一定的文化普适性。同时,不同因果定向对学业表现具有不同的预测作用,教育者有必要对学生进行因果定向的教育和引导。
