Reading Emotion From Mouse Cursor Motions: Affective Computing Approach

Affective computing research has advanced emotion recognition systems using facial expressions, voices, gaits, and physiological signals, yet these methods are often impractical. This study integrates mouse cursor motion analysis into affective computing and investigates the idea that movements of the computer cursor can provide information about emotion of the computer user. We extracted 16–26 trajectory features during a choice‐reaching task and examined the link between emotion and cursor motions. Participants were induced for positive or negative emotions by music, film clips, or emotional pictures, and they indicated their emotions with questionnaires. Our 10‐fold cross‐validation analysis shows that statistical models formed from “known” participants (training data) could predict nearly 10%–20% of the variance of positive affect and attentiveness ratings of “unknown” participants, suggesting that cursor movement patterns such as the area under curve and direction change help infer emotions of computer users.     

职场孤独感的形成原因与作用机理：基于调节匹配理论视角

随着组织广泛的信息技术运用、工作强度增加,员工之间面对面的、真诚的社交开始呈下降趋势。职场孤独感成了困扰员工的普遍问题,引起了企业管理实践界高度重视。通过综述已有文献,本文指出过往研究虽揭示了职场孤独感带来的消极影响效应并有效提高了组织对职场孤独问题的关注度,但尚未系统回答“如何预防与应对职场孤独感”。为了引导员工对职场孤独感的科学应对,本文认为有必要将员工视为能动的主角而非被动的承受者,并探讨职场孤独感与员工应对行为的关系,为如何应对职场孤独感提供建设性对策。 除此之外,为了更好地预防与遏制职场孤独感,有必要系统性地探讨职场孤独感的形成原因。综合过往研究,本文发现职场孤独感区别于其他消极情绪的核心在于：职场孤独感源自于高质量职场人际关系的缺失。与此观点对应的是,Wright和Silard （2021）认为当员工实际的职场人际关系未达到预期水平,员工会认为职场人际关系存在缺陷,产生孤独的体验。Wright和Silard （2021）的观点反映了职场孤独感是一种员工未实现期望社交目标而导致的心理体验。循此逻辑,本文采用与目标实现过程相关的调节匹配理论来解释职场孤独感的产生原因和影响机制,为预防和应对职场孤独感提供对策。以调节匹配理论为框架,本项目拟解决三个问题：（1）领导与下属的调节焦点（不）匹配如何通过影响领导成员交换,进而影响职场孤独感;（2）员工与团队的调节焦点（不）匹配如何通过影响团队成员交换,进而影响职场孤独感;（3）员工如何依据不同的团队调节氛围来选择社交应对策略,以及社交应对策略对员工绩效的影响。通过新颖的多项式回归分析与曲面响应分析方法,本文力求重构传统的职场孤独感的研究思路,为职场孤独感的产生机制提供新的研究视角。除此之外,本文首次将调节匹配理论引入职场孤独感的研究,系统性地分析了职场孤独感的产生和应对,呈现了职场孤独感现象在组织中的动态演化的过程与机制。     

抑制功能在疼痛中的作用

自生物心理社会模型提出以来, 利用心理因素预防和治疗疼痛备受关注, 越来越多的研究表明抑制功能在疼痛发展和恢复阶段起关键作用。疼痛诱发的自我防御机制通过争夺认知资源影响抑制功能, 反之低抑制功能个体在应对疼痛干扰中表现较差, 进而影响着疼痛的预期和学习。现有关于抑制功能影响疼痛的研究主要基于相关设计, 未来应进一步明确二者的因果关系。深入理解疼痛与抑制功能相互作用的认知机制有助于指导抑制功能对慢性疼痛的靶向干预。     

序列依赖效应——一种全新的“历史效应”

自2014年来, 研究者在视觉加工中发现一种全新的历史效应——序列依赖效应(当前刺激加工向先前刺激方向偏移的吸引性加工偏差)。近期研究发现：该效应广泛存在于视觉加工的各个层面(既包括朝向、空间位置、数量等低级特征, 也包括身份、吸引力、美感等高级属性); 其来源极为复杂(包括感觉编码、高级皮层的反馈调节、工作记忆、决策模板、感知与决策的级联等), 反映出不同层次的过往加工痕迹向当前认知的投射。针对该效应的典型特征、影响因素、认知与神经机制, 已涌现大量研究, 同时也存在严重争论, 亟待研究者深入探讨和厘清。     

工作时间与工作绩效的非线性关系：一项元分析

基于42篇文献的64项独立研究, 总样本量为22843人的数据, 对工作时间与工作绩效的非线性关系进行了元分析。结果发现：(1)工作时间与任务绩效、关系绩效之间存在显著的倒U型关系; (2)国家类型的调节作用显著：相对于西方欧美国家, 工作时间与任务绩效、关系绩效的倒U型关系在中国更为显著; (3)产业类型的调节作用显著：相对于劳动、资本密集型产业, 工作时间与任务绩效的倒U型关系在知识密集型产业中更为显著; (4)年龄的调节作用显著：相对于高年龄水平, 工作时间与任务绩效的倒U型关系在低年龄水平群体中更为显著; (5)性别的调节作用显著：相对于低男性比例, 工作时间与关系绩效的倒U型关系在高男性比例群体中更为显著。结果不仅基于元分析厘清了工作时间与工作绩效的倒U型关系效应, 而且为劳动法中工时规定(例如周均工作时间不超过44小时)的合理性提供了科学依据, 警示组织注意工作时间对工作绩效的“过犹不及”效应。     

测验与反馈在分段视频学习中的作用

分段原则是多媒体和视频学习中通过分段促进学习的重要原则。本研究探讨了测验和反馈对分段的影响。实验1对比了观看分段视频和在分段中进行测验两种情境,结果表明分段中测验会提高学习表现。实验2对比了分段视频、分段中测验和分段中测验并提供反馈三种情境。结果发现分段组与分段测验组之间没有差异,接受反馈的学习者学习表现最好。结果表明在分段视频中测验和反馈具有积极效应,对多媒体和线上学习具有潜在的意义。     

The Effects of Parental Education and Family Income on Mother–Child Relationships,Father–Child Relationships,and Family Environments in the People's Republic of China

Using a cross‐sectional design with 407 Chinese children aged 3–5 years and their parents, this study examined the effects of socioeconomic status, specifically parents' education and family income, on the children's mother–child relationships, father–child relationships, and the social environment in their families. The results indicated that income negatively predicted conflict in father–child relationships and positively predicted family active‐recreational environments. Income also positively predicted family cohesion among girls but not boys. Maternal education negatively predicted conflict in mother–child relationships and positively predicted closeness in mother–child and father–child relationships, family cohesion, and the intellectual‐cultural and active‐recreational environments in the family. Paternal education positively predicted family cohesion and intellectual‐cultural and active‐recreational environments. Income was found to partially mediate the effects of both maternal and paternal education on family active‐recreational environments. Findings are discussed in the frameworks of the family stress model and the family investment model.     

Frequency of borderline personality disorder among psychiatric outpatients in Shanghai

The objective of this study was to investigate the frequency, clinical characteristics, and comorbidity of borderline personality disorder (BPD) among psychiatric outpatients in two clinics at Shanghai Mental Health Center. A cross-sectional investigation was conducted. From 3,075 outpatients screened using the Personality Diagnostic Questionnaire-IV+, 2,284 patients positive for a personality disorder were assessed using the Structured Clinical Interview for DSM-IV Personality Disorders. The frequency of BPD among the psychiatric outpatients was 5.8%, with a frequency of 3.5% among males and 7.5% among females (p < .01). BPD was found to have extensive comorbidity with Axis I and II disorders. This study proves that BPD does occur in China. The detected frequency among outpatients is lower than that reported in North America.
