Evaluation of a self-instruction package for conducting stimulus preference assessments

Research suggests that inexperienced individuals cannot accurately implement stimulus preference assessments given written instructions alone. Training that includes written instructions supplemented with feedback from a professional with expertise in conducting preference assessments has proven effective; unfortunately, expert-facilitated direct training may not be widely available. In the current study, we used multiple baseline designs to evaluate the efficacy of an antecedent-only self-instructional package to train staff members to implement two methods of stimulus preference assessments. Accuracy was low when participants had access to written instructions alone. When access to enhanced written instructions was provided (i.e., technical jargon was minimized; instructions included pictures, diagrams, and step-by-step examples), inexperienced staff accurately implemented the assessments. Results are discussed in terms of opportunities to disseminate behavior-analytic technologies through self-instruction and print resources.     

Ill-health in Sweden 2005: Discontent in a modern welfare society and its relation to globalization

Abstract

The growing ill-health in Sweden is related to the crisis of the welfare state and to globalization and the expansion of a new virtual reality affecting the conceptualization of time and space, as well as to wider areas of human interaction, thinking, and ethical judgment. Fear and anxiety are emotional states of mind that have widespread effects on an individual level as well as on the whole of society.     

Exposure Therapy for Posttraumatic Stress Disorder: A Meta-Analysis

This meta-analysis compares the findings of empirical studies that employ either a traditional form of cognitive–behavioral-based exposure therapy or virtual reality exposure therapy (VRET) for the treatment of posttraumatic stress disorder (PTSD) to determine which is more viable and effective. Statistical analyses were performed on 26 studies to determine pre- to posttreatment effect sizes and interactions. Results demonstrated a trend toward significance in favor of traditional exposure therapy showing lower posttreatment PTSD. Limitations included a restricted number of relevant studies; future research on VRET for PTSD should orient more to experimental designs, larger samples, and increased use of control groups.     

虚拟团队中交互记忆系统理论研究现状述评

交互记忆系统(Transactive Memory System,TMS),团队成员在交流的过程中形成的一种合作性分工系统,简单来说就是团队成员对于“谁知道什么”的一种共同认知.通过TMS,团队成员能够协调彼此的专长从而提高团队知识整合和共享水平.文章回顾了TMS和虚拟团队的相关概念,重点从虚拟团队中TMS的形成、效用以及虚拟性与TMS的关系三个角度对虚拟团队中TMS的相关研究进行了归纳,最后指出未来不仅需要深入研究团队输入、输出和调节因素的影响,还需考虑到不同的信息技术的影响以及研究方法和范围的完善.     

Proteus效应：虚拟世界研究的新视角

随着虚拟世界的迅速发展,特别是虚拟现实环境与现实生活的日趋融合,虚拟现实环境对用户的影响引起了研究者的重视。在基于自我呈现的线上互动中,化身特点会有意或无意地影响到用户的知觉、态度和行为,即普罗透斯效应（Proteus Effect）。近年来,有研究者围绕着普罗透斯效应进行了一系列研究,对这一效应的概念、潜在发生机制、影响因素以及对用户个体和群体水平的影响等方面进行了一些探讨,并取得一定进展,这为国内学者开展虚拟世界中心理现象的探究提供了新的切入点。在未来研究中,普罗透斯效应的研究方法和范式仍需拓展,研究样本仍需丰富,本土化研究、跨文化研究以及应用研究也有待逐步展开。     

A multilevel multitrait‐multimethod analysis of self‐ and peer‐reported daily affective experiences

We examined the psychometric properties of an experience‐sampling measure of affect (PANAS) using data from self‐ and peer reports. A multivariate multilevel model was used to assess the reliability of the latent PANAS scales at the within‐ and between‐person level. Findings suggest satisfying internal consistencies for self‐ and peer reports of affective experiences at both levels of analysis. Convergent and discriminant validity of the two affect scales were examined by means of a multilevel multitrait‐multimethod approach (MLM‐MTMM) indicating distinct findings at the within‐ and between‐person level. These findings provide further insights into the structural relations between the two PANAS scales: Whereas positive and negative affect were unrelated at the between‐person level; they were negatively correlated at the within‐person level.

Tele‐analysis: the use of media technology in psychotherapy and its impact on the therapeutic relationship

A growing number of approaches in psychotherapy make use of internet‐ and other media‐based interactions. This paper discusses the impact on the therapist‐client relationship of using media technology and gives an overview of the current state of the debate. It is suggested that the technical conditions of internet‐based interactions produce new forms of social relationships that differ significantly from face‐to‐face‐interactions and that unconscious, nonverbal cues get lost. Research on the therapeutic interaction making use of ‘discourse linguistic’ methods is presented. The loss of nonverbal cues has implications for psychotherapy in general and especially for the treatment of patients who have difficulties relying on a secure therapeutic relationship. Emotional security in interactional relationships is transmitted to a much greater extent by nonverbal cues than by verbal content; psychoanalytic methods are specialized to refer to this level of interaction. Two alternative scenarios are discussed based on the psychoanalytic theories of Winnicott and Lacan: the risk of an illusionary, idealized image of the other and the possibility that cyberspace can be used for psychological development as a transitional space.     

虚拟团队共享心理模型与团队效能的关系

通过对62个虚拟团队的调研,检验了虚拟团队认同式共享心理模型与分布式共享心理模型构思,并运用多层线性建模技术,对团队特征变量、共享心理模型与虚拟团队效能间的关系进行了分析。结果表明：两类共享心理模型与团队效能间存在显著正相关;团队时间会影响共享心理模型与虚拟团队任务效能间的关系,团队时间会削弱认同式共享心理模型对任务效能间的正向关系,但能加强分布式共享心理模型对任务效能的正面影响;团队规模则主要影响共享心理模型对合作效能的效应,团队规模增加会加强认同式共享心理模型与合作效能间的相关,却会削弱分布式共享心理模型与合作效能间的关系     

虚拟现实购物网站的等级深度与宽度关系研究

为研究虚拟现实表征方式下,网上购物系统等级结构的宽度与深度特征对用户信息行为的影响,本文在实验室环境下研究了三种结构方式(8 6 1、16 3 1、4 4 3 1),结果初步发现:对于虚拟现实购物网站(或系统的虚拟现实表征方式),宽度的增加所带来的对用户信息搜索速度的损害大于深度的增加对用户信息搜索速度的损害,这与对二维表征方式下的既有研究结果相反;而且虚拟现实系统的8 6 1结构方式更容易带来用户的迷失。     

虚拟环境中的心理教育

虚拟技术和网络技术不仅为感觉通道提供了新的刺激呈现方式,而且也了为心理活动提供了新的活动空间和活动方式。各心理机能与虚拟环境之间形成了不同的主导性心理活动层面,具有不同的心理教育任务和目标。实现虚拟环境下的心理教育目标需要多元方法体系和工程体系的支持。
