山区高速公路空间郁闭度对驾驶员视觉及生理指标的影响

为了解高速公路空间郁闭度对驾驶员视觉行为和心理状态的影响规律,在山区高速公路开展室外实车试验,采用Dikablis眼镜式眼动仪和Varioport生理记录仪记录了驾驶员的眼动和生理数据,包括注视时间百分比、平均注视时间、扫视幅度、眨眼率、心电、心率、皮电等。结果表明,随空间郁闭度增加,驾驶员皮电和扫视幅度增大,眨眼率和平均注视持续时间减小,视点越来越集中。随着驾驶员的逐渐适应,空间环境对驾驶员的心理影响逐渐减弱。驾驶员主要关注中间靠左区域,目标物为中央分隔带和前方道路。开敞空间下驾驶员对右侧区域有少量关注。半郁闭空间下驾驶员皮电呈现规律性的波动,对于左侧区域的关注明显增多,对右侧区域的注视持续时间较长,视点集中点更远。     

Reciprocation wary employees discount psychological contract fulfillment

The present study examined the moderating role of reciprocation wariness in the association of employees' psychological contract fulfillment with psychosomatic strain and voluntary turnover, as mediated by perceived organizational support. To study these relationships longitudinally, 169 graduating college seniors were surveyed upon job acceptance and again 3 weeks, 3 months, 6 months, and 18 months following the start of employment. The findings showed that psychological contract fulfillment was positively related to perceived organizational support. However, this positive relationship was eliminated by reciprocation wariness, and this influence was carried over to psychosomatic strain and voluntary turnover. Thus, it appears that reciprocation wariness leads employees to discount psychological contract fulfillment as an indication of the organization's valuation and caring.

肺炎疫情期间医护人员心理危机干预效果分析

为提升医护人员心理健康水平,该文对肺炎疫情期间医护人员实施心理危机干预并分析其效果,以参与2020年1月25日-2月25日湖北省武汉市新冠肺炎疫情期间救治工作的300名医护人员作为研究对象,平均划分为实验组和对照组,其中针对实验组实施统一的心理危机干预训练,此期间对照组未参与训练但日常生活与实验组统一,选取四种量表分别对干预前后的两组实施测评。测评结果表明,干预后实验组的SCL-90各因子得分、SDS得分及SAS得分较干预前均下降明显,且下降幅度超过对照组;实验组干预后的GQOLI总得分与各维度得分均较干预前显著升高,且升高幅度高于对照组。综上,心理危机干预可显著提升医护人员的心理健康水平,缓解其心理紧张等症状,能够在一定程度上降低肺炎疫情期间医护人员的心理危机感。     

突发性灾难重大事件后公众对心理服务的认知和需求

为分析突发性灾难重大事件发生后公众对心理服务的认知和需求现状,采用随机抽样的方法在全国范围内抽取458名群众作为被试,使用“突发性灾难重大事件后公众心理服务认知和需求”调查问卷进行调查。结果显示:①不同性别人群、不同年龄阶段人群对“突发性灾难重大事件后心理服务”的认知存在显著差异(X^2=9.82,p<0.05;X^2=33.99,p<0.05)。②不同年龄阶段的人群对民众开展心理服务的必要性态度存在显著差异(X^2=15.84,p<0.05)。不同文化程度人群、不同性别人群对突发性灾难重大事件后心理服务活动的参与意愿存在显著差异(X^2=7.20,p<0.05;X^2=6.78,p<0.05)。③不同文化程度人群对心理服务知识和技能需求存在显著差异(X^2=28.65,p<0.05),在接受心理服务场所的选择上也存在显著差异(X^2=16.44,p<0.05)。不同年龄阶段人群对接受心理服务场所的选择上存在显著差异(X^2=21.52,p<0.05)。分析结果显示:在遭受突发性灾难重大事件时,公众对心理服务的了解程度一般,但参与意愿和需求强烈,因此,国家和社会应加快社会心理服务体系的建设,促进公众的心理健康。     

A double‐edged sword: The moderating role of conscientiousness in the relationships between work stressors,psychological strain,and job performance

Although conscientiousness was commonly viewed as a type of personal resource to help individuals reduce strain or mitigate the impacts of stressors, empirical research demonstrated mixed results. Based on the personal resource allocation perspective, we posited that rather than functioning as personal resource per se, conscientiousness may act as a key factor influencing how individuals allocate their personal resources. The current study examined the moderating roles of conscientiousness in the relationships that work stressors (i.e., challenge stressors and hindrance stressors) have with employee psychological strain and job performance by using multi‐source, time‐lagged data collected from 250 employees working at two companies. The results showed that both challenge stressors and hindrance stressors were positively related to psychological strain. Conscientiousness moderated the relationships between both stressors and psychological strain, such that the positive relationships were stronger for individuals with high conscientiousness. Conscientiousness also moderated the relationship between challenge stressors and performance, such that the relationship was positive for individuals with high conscientiousness but negative for those with low conscientiousness. Altogether, the findings suggest that conscientiousness acts as a double‐edged sword that both promotes performance and exacerbates the stress reaction of employees when they are confronted with stressful situations.

A process perspective on psychological contract change: Making sense of,and repairing,psychological contract breach and violation through employee coping actions

Psychological contracts are dynamic, but few studies explore the processes driving change and how employees influence them. By adopting a process approach with a teleological change lens, and drawing upon the sensemaking and coping literatures, this study positions individuals as active and adaptive agents driving contract change. Employing a mixed methodology, with a four‐wave longitudinal survey (n = 107 graduate newcomers) and qualitative interviews (n = 26 graduate newcomers), the study focuses on unfolding events and develops an “adaptive remediation” process model aimed at unraveling contract dynamics. The model demonstrates how breach or violation events trigger sensemaking, resulting in initially negative employee reactions and a “withdrawal” of perceived contributions, before individuals exercise their agency and enact coping strategies to make sense of, and adapt and respond to, these discrepancies. A process of contract “repair” could then occur if the coping actions (termed “remediation effects”) were effective, with individuals returning to positive exchange perceptions. These actions either directly addressed the breach and repaired both it and the psychological contract (termed “remedies”) or involved cognitive reappraisal of the broader work environment and repaired the contract but not the breach (termed “buffers”). The results highlight the unfolding, processual nature of psychological contracting. Copyright © 2015 John Wiley & Sons, Ltd.

沙漠公路驾驶员心理、生理特性初探

针对沙漠公路交通安全现状,采用动体视力、速度估计、复杂(选择)反应、处置判断、血压脉搏检测仪等驾驶适宜性检测仪器,就长期从事沙漠公路运输活动的驾驶员群体进行了包括视觉、速度估计、反应、判断等在内的心理、生理特性的实地测试。检测结果初步表明,沙漠公路特殊的线形布设和修筑技术特征以及沿线的自然环境条件,使得驾驶员表现出有别于一般绿洲公路的驾驶心理和行为特性,其主要表现在在沙漠环境中,驾驶员的动体视力要较静体视力受到更大的影响;急躁心理影响,沙漠公路驾驶员的速度估计和复杂反应时间相应指标值均小于全国平均水平;沙漠公路驾驶员复杂反应错误次数和处置判断错误次数均高于绿洲公路。
