中国优秀运动员6项心理技能研究

本研究采用标准化《运动心理技能问卷》并结合其它测试数据,对151名中国优秀运动员作了研究,结果表明:1.中国优秀运动员已初步掌握了焦虑控制(AX)、集中注意力(CC)、提高自信心(CF)、提高动机水平(MV)和加强集体意识(TM)的心理技能,他们在自信心和集体意识方面表现非常突出,而在心理准备(MP)方面则表现欠缺;2.除运动动机方面外,中国优秀运动页未表现出心理技能的差异性;3.运动等级(技术水平)不同,运动员的心理技能有差别;4.根据中国优秀运动员心理技能可以把他们分成4种类型,它们是心理技能发展水平较低的心理准备型和自信心型;心理技能发展水平较高的自信心——集体意识型和自信心——集中注意力型。

人声加工的神经机制

人声是人类听觉环境中最熟知和重要的声音, 传递着大量社会相关信息。与视觉人脸加工类似, 大脑对人声也有着特异性加工。研究者使用电生理、脑成像等手段找到了对人声有特异性反应的脑区, 即颞叶人声加工区(TVA), 并发现非人类动物也有类似的特异性加工区域。人声加工主要涉及言语、情绪和身份信息的加工, 分别对应于三条既相互独立又相互作用的神经通路。研究者提出了双通路模型、多阶段模型和整合模型分别对人声的言语、情绪和身份加工进行解释。未来研究需要进一步讨论人声加工的特异性能否由特定声学特征的选择性加工来解释, 并深入探究特殊人群(如自闭症和精神分裂症患者)的人声加工的神经机制。     

A multiplex view of leadership structure in management teams

In the hope of complementing the structural perspective in upper echelon research and advancing a fine-grained understanding of dyadic leadership influence in management teams, the current study combines two types of intrateam structures—leadership network and friendship network—to create a multidimensional conceptualization of leadership structure in management teams. Specifically, we propose that management teams with a denser singular leadership network (i.e., a network consisting of many leadership ties that are not coupled with friendship ties) should have lower management team cohesion, which subsequently renders worse business unit performance. To contrast, management teams with a denser multiplex network (i.e., a network consisting of many leadership ties that are coupled with friendship ties) should have higher management team cohesion, which subsequently renders better business unit performance. Guided by structural contingency perspective, we further propose that management team task interdependence will strengthen team cohesion's positive impact on business unit performance. To test the hypothesized model, we collected team-level social network data and multiple-wave survey data from 697 managers nested in 148 hotels (i.e., 148 management teams) owned by a large hospitality company. We also obtained objective performance data for each hotel (i.e., occupancy percentage rate and revenue per available room per day) as the criterion measure. The data supported our hypotheses. The theoretical and practical implications of our findings are discussed.     

Simple Threshold Rules Solve Explore/Exploit Trade-offs in a Resource Accumulation Search Task

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade-offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold-based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non-decreasing thresholds. Decreasing threshold strategies that “front-load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.     

死亡凸显对自我姓名注意瞬脱对抗效应的影响

已有研究表明死亡凸显会抑制自我面孔和自我参照记忆加工的自我优势,可是死亡凸显对自我姓名的影响尚不明确,本研究采用事件相关电位技术,探索死亡凸显对自我姓名注意瞬脱对抗效应及其大脑神经活动的影响。58名被试在经历不同的启动任务后,完成自我姓名、朋友姓名和名人姓名的注意瞬脱任务。行为结果发现自我姓名识别正确率显著高于朋友姓名和名人姓名,表现出稳定的自我姓名加工的注意瞬脱对抗效应;电生理数据发现死亡启动后自我姓名诱发的P300波幅显著低于消极启动组和中性启动组,而朋友姓名和名人姓名并不受启动的影响。本研究结果与以往研究结果共同表明死亡想法凸显会使个体将抑制自我加工（自我姓名、自我面孔和自我参照记忆）作为应对远端死亡焦虑的一种手段。     

新冠肺炎疫情期间大学生价值观特征及变化趋势探究

社会价值观对于社会群体具有重要的导向和动力作用,而社会重大事件的发生会对社会价值观的走向产生影响。研究采用价值观类型量表,对908名大学生进行调查,其中包含144名湖北省大学生,探究新冠肺炎疫情期间大学生价值观的分布特征,对比湖北省和其他地区,以及与SARS时期的异同,并预测其在疫情后期的变化趋势。结果显示:(1)在大学生的总体样本中,实用型、社会型和科学型价值观依次占据重要地位;(2)湖北省大学生中社会型价值观占据主导地位,其他地区大学生中实用型价值观占据主导地位,两个样本的整体分布特征不存在显著差异;(3)两次疫情中,社会型和实用型价值观均占据主导地位,科学型价值观的地位显著提升。     

童年期创伤对大学生抑郁的影响:早期适应不良图式和负性生活事件的作用

目的:考察早期适应不良图式、负性生活事件在童年期创伤与大学生抑郁间的影响机制。方法:采用童年期创伤问卷、Young图式问卷短版中文修订版、青少年生活事件量表及90项症状自评量表对1423名大学生进行调查,结果表明:(1)童年期创伤既可以直接正向预测大学生抑郁,也可以通过早期适应不良图式中的分离和拒绝、自主性及能力受损两大图式类别间接地正向预测大学生抑郁;(2)负性生活事件调节了早期适应不良图式在童年期创伤与抑郁间的中介作用     

中国人善良人格量表的编制及信效度检验
