虚拟场景中的信息类型对路径整合效率的影响

空间巡航中常采用路径整合进行位置追踪及方向更新,本研究利用返回起点任务,通过对虚拟场景中不同信息类型的设置,探讨地标、纹理、双线索（地标+纹理）及纯色条件下路径整合效率的差异。结果发现,除角度误差外,双线索条件下路径整合效率显著较高,其次是地标条件,纹理条件次之,纯色条件下表现最差。结果表明,不同信息类型下路径整合效率存在显著差异,且双视觉信息较单一视觉信息条件下的整合效率更优。     

家长式领导对多层面创造力的作用机制

作为一种具有中国文化特色的领导模式, 家长式领导对多层面的创造力均有显著影响。基于对以往实证研究的分析, 文章针对家长式领导及其维度与多层面创造力之间的直接关系、交互效应、调节效应与作用机制等问题进行了梳理与阐述, 构建了“家长式领导影响员工及团队创造力的作用机制”模型; 进而指出, 家长式领导对员工创造力的作用受到工作情境、个体因素的调节效应并有赖于个体心理认知和社会关系的中介作用, 它还以团队认知和团队互动为中介作用于团队创造力。未来研究应努力拓展研究层次, 丰富研究方法, 并从跨文化视角系统探索家长式领导对多层面创造力的作用机制。     

Getting connected: Intergroup contact on Facebook

One correlational study examined whether virtual contact via Facebook is positively related to intergroup relations. The followers of two online campaigns from Iran and Israel—whose countries have been in a politically hostile relationship since the 1980s—indicated the amount of direct and indirect virtual (Facebook) and real-life outgroup contact they have had, a number of quality and affective judgments about that contact, and completed an affective prejudice measure about the respective outgroup. Overall, contact was negatively associated with affective prejudice, providing support for the contact hypothesis in a specific and exclusively virtual setting with citizens of hostile nations. Previously experienced real-life contact did not moderate the results, suggesting that virtual contact has an independent link to positive outgroup attitudes.     

认知行为疗法在儿童社会退缩行为干预中的新进展

社会退缩行为指儿童在社会情境中抑制自己参与同伴互动并表现出独处的行为。社会退缩阻碍儿童形成良好的社交能力,影响其人格和认知的健康发展,因而对儿童社会退缩行为进行及时干预显得十分重要。研究对认知行为疗法在儿童社会退缩行为干预中的进展进行了整合,包括虚拟现实暴露疗法、学校情境下的认知行为治疗及网络认知行为治疗。未来研究应设计针对社会退缩行为不同亚类型的干预方案,以及在干预中重视情绪调节的训练和教师的介入。     

Shared leadership development and team performance: A new look at the dynamics of shared leadership

The present study offers new theoretical insights into the dynamics of shared leadership. Integrating arguments from shared leadership and team development theory, we examine how shared leadership changes over the course of a project team's life cycle and how this pattern of change relates to team performance. Guided by shared leadership theory and project team literature, we also explore team‐level factors, which may alter the pattern of shared leadership development. In particular, we propose that in project teams shared leadership develops in a nonuniform way, approximating an inverted U‐shaped pattern, increasing early in the team's life cycle, peaking around the midpoint, and then decreasing in the later phase. In turn, this development pattern relates positively to team performance. We also extend theory by explaining how specific team characteristics influence the pattern of shared leadership development. Using a three‐study approach, we empirically examine the hypothesized relationships and conclude with a general discussion of the theoretical and practical implications of our findings.     

Comparison between two continuous performance tests for identifying ADHD: Traditional vs. virtual realityEjecución continua para la detección del TDAH: pruebas tradicionales frente a la realidad virtual

Background/Objective: Continuous Performance Tests (CPTs) have demonstrated validity when differentiating children with ADHD from healthy controls. However, these CPTs have limitations such as low ecological validity. New CPTs based on the use of Virtual Reality (VR) have appeared as supposedly improved methods for assessing ADHD. This study aims to compare the discriminant value of attentional variables produced by a VR CPT (Aula Nesplora) with that of variables from a traditional CPT (Test of Variables of Attention; TOVA) for identifying ADHD. Method: A total of 338 children aged between 6 and 16 years old (M = 10.84, SD = 3.01) participated in the study: 31.95% correspond to the inattentive presentation, 15.38% to the impulsive-hyperactive presentation, 22.78% to the combined presentation, and the remaining 29.88% correspond to children without ADHD. Results: Results indicated that Aula Nesplora predicts ADHD presentations better than TOVA. It also differentiates better between ADHD and non-ADHD students. Conclusions: These findings show the potential advantages of using virtual reality in ADHD assessment, as it facilitates the diagnosis of ADHD and the differentiation of its presentations in a realistic environment.     

Long-term spatial clustering in free recall

We explored the influence of space on the organisation of items in long-term memory. In two experiments, we asked our participants to explore a virtual environment and memorise discrete items presented at specific locations. Memory for those items was later on tested in immediate (T1) and 24 hours delayed (T2) free recall tests, in which subjects were asked to recall as many items as possible in any order. In experiment 2, we further examined the contribution of active and passive navigation in recollection dynamics. Results across experiments revealed a significant tendency for participants to consecutively recall items that were encountered in proximate locations during learning. Moreover, the degree of spatial organisation and the total number of items recalled were positively correlated in the immediate and the delayed tests. Results from experiment 2 indicated that the spatial clustering of items was independent of navigation types. Our results highlight the long-term stability of spatial clustering effects and their correlation with recall performance, complementing previous results collected in immediate or briefly delayed tests.     

Development of a cognitive function test using virtual reality technology: examination in healthy participants

We developed a virtual reality test to assess the cognitive function of Japanese people in near-daily-life environment, namely, a virtual shopping test (VST). In this test, participants were asked to execute shopping tasks using touch panel operations in a “virtual shopping mall.” We examined differences in VST performances among healthy participants of different ages and correlations between VST and screening tests, such as the Mini–Mental State Examination (MMSE) and Everyday Memory Checklist (EMC). We included 285 healthy participants between 20 and 86 years of age in seven age groups. Therefore, each VST index tended to decrease with advancing age; differences among age groups were significant. Most VST indices had a significantly negative correlation with MMSE and significantly positive correlation with EMC. VST may be useful for assessing general cognitive decline; effects of age must be considered for proper interpretation of the VST scores.     

School-based care and support for the intellectually disabled learners at risk for sexual abuse: South African teacher carer perspectives

This study examined the functionality of a school-based care and support program for the intellectually disabled learners who have a history of sexual abuse. Participants were 28 teachers from four special educational needs schools in the Gauteng Province, South Africa (females = 80%; age range 30 to 55 years). The teachers participated in a focus group discussion on the extent to which the school-based care and support for learners with intellectual disability worked to the intended goals and procedures. Thematic analysis of the data suggested the school care and support program to work to purpose within the school system and with partner non-governmental organisations; but less so with the local school district personnel.
