慢性军事应激致军人海马形态、认知功能和应对方式的变化

通过对572名连续4~16个月高强度军事训练的军人进行SCL-90测评, 研究慢性军事应激条件下军人海马形态、认知、心理特质和特质应对方式的变化特征。将其中l7例焦虑因子分≥3分者(焦虑或伴焦虑)设为研究组(A), 并以匹配法设对照组(B)。检测两组军人血皮质醇, 并用MRI观察海马形态、检测简单和复杂认知作业功能、以STAI测评状态-特质焦虑及以CCSQ测评应对方式, 探讨两组对应变化。研究结果显示：(1)血皮质醇：A、B组均高于正常水平, 有差异显著, A组显著高于B组。(2)海马形态：A组与B组MRI海马形态标准化后, A组海马形态显著萎缩, 与B组相比有显著性差异, 但各组每个同体的左右两侧之间相比无显著性差异。(3)认知作业功能：A组简单认知作业成绩与B组无显著差异, 但复杂认知作业成绩与B组相比有显著性差异。(4)状态-特质焦虑：A组的状态焦虑、特质焦虑分别与B组和常模比较均有显著变化, B组与常模相比状态焦虑变化显著, 特质焦虑变化不显著。(5)应对方式：A组积极应对方式平均值低于B组和常模并有显著性差异, B组高于常模; A组消极应对方式平均值高于B组和常模且有非常显著性差异, B组与常模无显著改变。结论 在慢性军事应激条件下, 特质焦虑个体的海马形态出现双侧萎缩, 复杂认知功能下降, 更易发生状态焦虑, 行为取向表现出积极应对方式降低、消极应对方式增加。     

试论19世纪上半叶英国的工厂立法

英国工业革命时期工厂制的出现引发了诸多严重的问题,19世纪上半叶的工厂立法正是为解决这些问题所作的最初努力。这一时期立法的指导思想是旧的家长主义,而所要解决的问题又是工业化过程中出现的新问题。这种新旧矛盾造成了这一时期立法覆盖面狭窄和实施效果不理想等不足,但却延续了前工业社会国家干预的传统,并为其后的国家干预开辟了道路。

气质和儿童同伴交往类型关系的研究

该文采用问卷法和社会测量法相结合的方法,以班级为单位对484名3~9岁儿童的气质和同伴关系类型的关系进行研究。结果表明:3~9岁儿童同伴关系类型已形成分化,其中被忽视儿童和被拒绝儿童所占总体样本的比例分别为16.9%和9.6%,比例较高值得重视。儿童气质对同伴交往类型的形成影响很大,四种同伴关系交往类型在气质各维度上方差检验都达到了差异显著,有着明显不同的气质特点。     

从生育态度看思维方式对个体传统性与现代性的影响

本研究旨在从人们的生育态度中探讨中国人思维方式对传统性与现代性有何影响。研究分两部分:第一部分用相关研究的方法探讨思维方式与中国人的传统性与现代性的关系;第二部分设计了一个能够反映中国人传统性和现代性的情境问卷,通过测量人们的生育态度,来进一步证实思维方式对传统性和现代性的影响。通过对257名被试问卷调查结果的分析发现:思维方式和中国人的传统性与现代性之间有着密切的关系,对情境问卷的进一步分析发现思维方式和情境因素一起影响人们的生育态度。研究结果对我们理解中国人思维方式的影响有着重要的理论和实际价值。     

Pilot study for assessing the behaviors of patients with schizophrenia towards a virtual avatar.

This study examined whether a virtual avatar could be perceived as a real human by patients with mental disease, especially schizophrenia, as well as whether a virtual avatar could be applied to acquiring patients' behavior characteristics in a short conversation situation. The virtual avatar has been used for various applications which need to communicate with other person or to train or educate by showing humanlike behavior. Recently, many researches have shown that the virtual avatar technology has been enhanced and the avatar could be perceived like real human. A virtual avatar, standing in a virtual room, was designed for this study. Tasks to approach, initiate a talk, and answer to avatar's questions was assigned to the 11 patients with schizophrenia. As behavioral parameters in the virtual environment, the interpersonal distance and the verbal response time were acquired. In addition, the Positive and Negative Syndrome Scale (PANSS) for patients was administered in order to investigate the relationship between patients' symptomatic characteristics and behavior parameters. The interpersonal distance was negatively correlated with the negative syndrome scale, a subscale of PANSS, which is consistent with previous research reporting the relationship between interpersonal distance and a real person's image. The verbal response time, however, was not correlated with any other subscale of PANSS. After analyzing subitems of the negative syndrome of PANSS, two positive correlations were found: one was with blunted affect and the other was with poor rapport. We concluded that the virtual avatar could be perceived as a real human by schizophrenic patients and the avatar could draw the schizophrenic patients' behavior characteristics.     

Integrating haptic-tactile feedback into a video-capture-based virtual environment for rehabilitation.

Video-capture virtual reality (VR) systems are gaining popularity as intervention tools. To date, these platforms offer visual and audio feedback but do not provide haptic feedback. We contend that adding haptic feedback may enhance the quality of intervention for various theoretical and empirical reasons. This study aims to integrate haptic-tactile feedback into a video capture system (GX VR), which is currently applied for rehabilitation. The proposed multi-modal system can deliver audio-visual as well as vibrotactile feedback. The latter is provided via small vibratory discs attached to the patient's limbs. This paper describes the system, the guidelines of its design, and the ongoing usability study.     

The Career Adapt-Abilities Scale in Macau: Psychometric characteristics and construct validity

The purpose of the study was to determine if the CAAS could be used with middle school students. Currently no study has been done for the application of CAAS on middle school students. We examined the reliability and validity of the Career Adapt-Ability Scale (CAAS) in Macau for middle school and high school students. The CAAS consists of four scales, each with six items, which measure concern, control, curiosity, and confidence. We tested the internal consistency and factor structure with 270 middle school students and 188 high school students. We also compared students' performance on CAAS in terms of gender and age. The results indicated that internal consistency estimates for the subscale and total scores were good for both high school and middle school students. The factor structure was quite similar to the one computed for combined data from 13 countries (Savickas & Porfeli, 2012). In addition, we found that high school students scored significantly higher than middle school students on the CAAS scales. Based on the results, the CAAS-Macau Form appears ready for use by researchers and practitioners who wish to measure adaptability resources among middle school and high school students in Macau.     

Virtual Reality Exposure Therapy for PTSD symptoms after a road accident: an uncontrolled case series

This report examined whether Virtual Reality Exposure Therapy (VRET) could be used in the treatment of posttraumatic stress disorder (PTSD) symptoms in the aftermath of a serious motor vehicle accident. Six individuals reporting either full or severe subsyndromal PTSD completed 10 sessions of VRET, which was conducted using software designed to create real-time driving scenarios. Results indicated significant reductions in posttrauma symptoms involving reexperiencing, avoidance, and emotional numbing, with effect sizes ranging from d=.79 to d=1.49. Indices of clinically significant and reliable change suggested that the magnitude of these changes was meaningful. Additionally, high levels of perceived reality ("presence") within the virtual driving situation were reported, and patients reported satisfaction with treatment. Results are discussed in light of the possibility for VRET to be useful in guiding exposure in the treatment of PTSD following road accidents.
