Role of visual-perceptual skills (non-motor) in children with developmental coordination disorder

The purposes of this study were to examine test-retest reliability of the Test of Visual-Perceptual Skills (Non-Motor)-Revised (TVPS-R), to explore motor-free visual-perceptual skills, and to categorize subtypes thereof in children with developmental coordination disorder (DCD). One hundred and seventy-eight children, aged 9 and 10 years, identified as having DCD with the Movement Assessment Battery for Children (M-ABC), were assessed, along with 200 typically developing children. The results showed good test-retest reliability for the total perceptual quotient scores of the TVPS-R, but not for all subtests. Children with DCD performed significantly poorer compared to typically developing children on the visual-perceptual test, but the deficits were not common to all children with DCD. This study supported the stance that we should consider the heterogeneous characteristics of children with DCD when designing experimental studies or developing educational interventions.     

熟悉主题说明文阅读推理加工的认知神经机制

采用功能磁共振成像(Functional Magnetic Resonance Imaging, fMRI)技术对熟悉主题说明文阅读过程因果推理加工进行研究, 探讨说明文阅读过程中读者是否能够自发进行因果推理加工, 以及阅读焦点的存在是否会对说明文阅读过程中的因果推理加工产生影响。结果表明, 读者在熟悉主题说明文阅读过程中能够自动进行推理加工, 负责推理加工的主要脑区为额叶(尤其是额下回)、顶叶下部及双侧楔前叶等区域。在熟悉主题说明文阅读过程中, 阅读焦点的存在一定程度上使读者的认知加工资源集中在对与焦点相关的推理关系的加工上。     

疼痛表征在自我和他人间的一致性效应

在以往研究中“pain matrix”被认为是加工自我和他人疼痛信息的特异性神经机制, 也可能是个体对他人疼痛共情的原因。但是最近的研究发现非疼痛的感觉刺激也能激活该脑区, 因此疼痛表征在自我和他人间是否存在一致性受到质疑。研究采用启动范式从两个方面入手探索自身疼痛和疼痛共情间是否存在一致性关系。实验一使用疼痛和非疼痛图片为启动刺激, 疼痛或热刺激为靶刺激, 发现相对于非疼痛图片, 疼痛图片启动下被试对自身疼痛刺激的反应时减少, 疼痛水平和情绪反应增强。实验二使用疼痛和热刺激为启动刺激, 疼痛或非疼痛图片为靶刺激, 发现相对于热刺激, 疼痛刺激启动下被试对疼痛图片的反应时减少。同时, 在两个实验中非疼痛的靶刺激都不受启动刺激的影响。这说明疼痛表征在自我和他人间存在一致性效应。     

人的老化与社会情绪选择理论

当今世界人口老龄化带来的诸多影响日益受到人们的关注与重视,老化研究也逐渐成为心理学家关注的热点。社会情绪选择理论是基于老化问题而提出的一个新理论。总结这一理论的基本假设和理论框架,并对目前有关此理论的实证研究进行了整理概括,最后指出了该领域尚存在的一些问题,并对未来前景进行了展望。     

青年脑卒中的病因探讨

近年来脑卒中的发病有年轻化的趋势,青年脑卒中越来越普遍并严重影响着青年人的生活质量。青年脑卒中的患病率虽然低于老年人,但对患者本人身体、精神方面造成的损害,对家庭及社会所造成的影响,甚至更为严重。因此,防治青年脑卒中有着十分急迫的重要意义。本文旨在探讨青年脑卒中可能的发病原因,为临床及早诊断和及时干预提供理论依据。     

全真道初传四川地区小考

作为道教的发源地,四川地区的道教活动自古至今绵延不绝,不过,随着张天师率领道民北迁,蜀地道教活动的声势似乎有所减弱,尤其是全真道于十三世纪在中国北方兴起后,蜀地道教更较少成为人们关注的焦点.事实上,四川地区的全真道曾在中国道教界扮演过重要角色,如青城山、青羊宫等蜀中名山宫观多属全真道活动的重镇,而易心莹、傅圆天等四川地区的道长也曾成为中国道教界的领袖.然而,有关全真道在四川地区的传布历史却鲜有人进行过深入讨论,令人颇感遗憾.笔者不揣浅陋,试对全真道初传四川地区的时间考论如下.     

Catastrophizing as a Cognitive Vulnerability Factor Related to Depression in Workers’ Compensation Patients with Chronic Musculoskeletal Pain

The purpose of this study was to examine the role of catastrophizing as a mediator and moderator between life stress and depression in a sample of workers’ compensation patients with chronic musculoskeletal pain. Pain intensity, life stress (especially work and financial stress), and catastrophizing contributed significantly to depression. Catastrophizing was found to be partially mediating the relationship between life stress and depression and a moderator between social stress and depression. The results supported the role of catastrophizing as a cognitive vulnerability-stress factor related to depression in chronic pain patients. Screening for life stress and intervening early to prevent catastrophizing from occurring in the workers’ compensation rehabilitation process may reduce psychosocial distress and enhance the overall effectiveness of rehabilitation programming for workers’ compensation patients with chronic pain.     

Exploratory and confirmatory factor analyses of the structured interview for disorders of extreme stress

Two studies were conducted to provide the first empirical examination of the factor structure of a revised version of the clinically derived Structured Interview for Disorders of Extreme Stress, a structured interview designed to assess associated features of posttraumatic stress disorder (PTSD) thought to be related to early onset, interpersonal, and prolonged traumatic exposure. Five factors representing demoralization, somatic dysregulation, anger dysregulation, risk/self-harm, and altered sexuality were derived from an exploratory factor analysis conducted with adult trauma survivors in substance abuse treatment. They provided a good fit in a confirmatory factor analysis conducted in a second study with a nonclinical sample of ethnoculturally diverse, socioeconomically disadvantaged, incarcerated adults. Evidence of the derived factors' internal consistency and convergent and discriminant validity is reported. Evidence supported the association of these factors with interpersonal trauma (physical and/or sexual), its repetition, and its earlier onset. Implications for clinical assessment of complex posttraumatic stress disorder are discussed.     

Exploring the personality trait of self-monitoring on technology usage of Web portals.

This study explores the personality trait of self-monitoring in Web portal usage by employing the extended theory of planned behavior (TPB) model of Pavlou and Fygenson. A survey of 254 Internet Web portal users was conducted to test the hypothesized model. The results show that our data supported all five individual causal paths postulated in this study. Further, the construct of self-monitoring plays a moderating role in Web portal usage; three of the five moderating hypotheses are supported. Based on the research findings, conclusions and implications are discussed.
