The My Emotions Questionnaire: A self-report of mothers’ emotional responses to infant crying

The purpose of this article was to examine the psychometrics of the My Emotions Questionnaire, a self-report designed to assess mothers’ emotional reactions when their infants cry. Participants were 240 first-time mothers. When infants were 6 months and 1 year old, mothers completed the new questionnaire and measures assessing beliefs and behavioral responses to infant crying, and interview-based measures of mothers’ emotional reactions and causal attributions about crying were administered. Maternal sensitivity and negative behaviors were observed when infants were 6 months and 1 and 2 years old. Mothers reported on their discipline practices when children were 2 years old. Five emotion factors emerged based on exploratory factor analysis (EFA) of the 6-month data: Amusement, Anxiety, Frustration, Sympathy, and Protective. The five-factor structure was supported via a confirmatory factor analysis (CFA) of the 1-year data. All scales demonstrated adequate internal consistency reliability and significant stability from 6 months to 1 year. Amusement, Frustration, and Protectiveness demonstrated the best convergent validity with cry cognitions and predictive validity to parenting measures, followed by Anxiety, although effects tended to be small to moderate. Evidence for the validity of Sympathy was less compelling. The potential utility of the questionnaire for basic and applied research is discussed.     

周代士婚礼对中国古代王室婚礼的影响

中国传统婚礼礼仪来源于儒家礼学经典著作《仪礼·士昏礼》中所反映的周代婚姻六礼,但这些礼仪是怎样影响中国古代的王室婚礼,时至今日没有任何学者对此作过全面系统的解释并得出令人信服的结论。文章运用比较研究的方法,从议婚到结婚过程中的文辞话语和仪式要素两个方面,全面深入地比较了周代士婚礼与秦汉以后部分朝代王室婚礼的共同性和差异性。就此认为,中国古代以汉族为主的历代王室婚礼的基本范式均来自于周代的士婚礼,以其他民族为主建立政权而形成的王室婚礼则具有各自的区域民族特色,从而使得中国古代的王室婚礼在总体上形成了一种具有二元结构的仪式象征符号体系。     

Delayed response, preoperative overtraining, and prefrontal lesions in the rat

An earlier study in this laboratory found that preoperative overtraining improved retention of a delayed alternation task after prefrontal lesions in the rat. In this study, however, it was found that preoperative overtraining did not improve performance of the rat in a delayed response task following prefrontal lesions. These results support the hypothesis that preoperative overtraining can improve postoperative performance only when postoperative recovery is ordinarily present, as it is with delayed alternation. but not with delayed response, in the prefrontal rat. This suggests that effects of preoperative overtraining and postoperative recovery may be mediated by similar mechanisms. It further suggests that a shift of function, which seems to account for postoperative recovery, may occur in some parts of the normal adult brain as a result of overtraining.     

触觉二维图像识别中2D-3D空间信息转换的认知机制

可触摸的触觉二维图像是视觉障碍人群获取图像信息的重要方式。目前大多数触觉二维图像都是直接由视觉二维图像转化为的可触摸线条图。在视觉二维图像中,通常运用透视和视角等视觉原理将三维空间关系转换为二维平面关系。视觉系统经过长期大量知觉学习,习得了这种二维到三维的映射关系。但是触觉识别二维图像时,触觉系统如何建立二维平面与三维空间的映射,目前尚有待进一步的研究。影响触觉识别二维图像中二维-三维空间信息转换的视觉因素主要有透视、视角、遮挡、纹理梯度和镂空,直接将视觉二维图像转化为的触觉二维图像时,图像中包含的上述视觉因素通常会干扰触觉识别。结合已有研究,试图提出“双表象加工模型”来解释触摸二维图像时二维到三维空间信息转换的认知机制。该模型认为触觉识别二维图像依赖于两个表象系统的整合,即物体表象系统(涉及物体的大小、形状和纹理)与空间表象系统(涉及物体的空间关系、透视和视角)。两种表象系统的信息最终进行整合,在物体表象和空间表象成功匹配的基础上建立二维图像与三维空间之间的映射,通达长时记忆中的三维物体表征。双表象加工模型将有助于我们深入认识触知觉的认知机制,也将为触觉二维图像的设计提供理论依据。     

Attachment,Social Support,Resilience and Posttraumatic Stress Disorder Symptoms in Chinese Adults Living with HIV/AIDS

The present study aimed to examine the effects of attachment, social support and resilience on posttraumatic stress disorder (PTSD) symptoms in people living with HIV/AIDS. One hundred fifty-two HIV+ adults in China were investigated. The results suggested that attachment anxiety had a significant direct effect on PTSD symptoms and impacted PTSD symptoms indirectly though associations with social support and resilience. Attachment avoidance could also be considered a distal risk factor of PTSD symptoms via the mediation of social support and resilience. The findings highlight the importance of identifying trauma and PTSD symptoms in people affected by HIV/AIDS and suggest that people with attachment anxiety and low social support resources might be at high risk for PTSD.     

高校毕业生可雇佣能力的因素、结构与测量

该研究在文献理论分析、招聘广告词频分析、专家反馈、焦点团队访谈和半开放式问卷调查的基础上,编制了高校毕业生可雇佣能力问卷,并对已签订就业协议的930名高校毕业生进行了施测。探索性和验证性因素分析结果表明高校毕业生可雇佣能力是一个多层次多维度的结构,主要包括15个基本因素,分别归属于5个二阶维度和一个三阶维度,量表的信、效度指标均达到心理测量学要求。     

青少年孤独感与人格五因素的关系:人际关系能力的中介作用

该研究采用小五人格问卷、中学生孤独感问卷和人际关系能力问卷,以784名青少年为被试,考察青少年孤独感的特点及其与人格五因素、人际关系能力的关系。结果发现:(1)青少年的孤独感存在显著的性别差异,男生显著高于女生;(2)在孤独感各维度中,除同伴关系评价与开放性的相关不显著外,其他维度与人格各维度及人际关系能力间均相关显著;(3)人格的情绪性和开放性显著正向预测孤独感,外向性、宜人性和人际关系能力显著负向预测孤独感;(4)在外向性、情绪性及开放性与孤独感的关系中,人际关系能力起部分中介作用,而在宜人性与孤独感的关系中,人际关系能力起完全中介作用。     

随机支持模型:青少年主观概率校准的特点

随机支持模型试图以假设支持为随机变量的方式描述主观概率的校准。采用随机配对的60个中国城市户籍人口的比较任务验证了该模型对初中、高中和大学生的适用性。研究还表明青少年主观概率校准的发展特点:青少年的正确率随年龄的增长而提高;主观概率判断(信心)不同年龄有显著差异,大学生信心最强,其次是初中生、再次是高中生;大学生主观概率判断的极端性最强,其次是初中生,再次是高中生;青少年的主观概率校准是过度自信的。     

语音信息对中国英语学习者语义加工的影响及其脑机制

本研究采用经典的句尾畸义词诱发N400的ERP实验范式探讨了中国英语学习者在进行英文阅读时语音的影响及其相关脑机制。实验包括两类畸义语句:1.同音畸义:句尾词有畸义,但语音和相应正常语义句尾词相同;2.非同音畸义:句尾词有畸义,且语音和相应正常语义句尾词不同。行为数据显示:在错误率上同音畸义显著地高于非同音畸义。ERP显示:无论在早期(N100)还是晚期(N400)脑电成份上,同音畸义和非同音畸义的ERP振幅都有明显差异。本研究从行为和脑电两个方面一致揭示中国英语学习者阅读英文时受到了语音的影响。
