Dynamic action in virtual environments: Constraints on the accessibility of action knowledge in children and adults

In a series of three experiments, we probed the accessibility of action knowledge in different versions of a virtual environment (VE) with 7-year-old children and adults. Using a PHANToM^TM haptic interface, participants performed a virtual throwing task in which they tried to propel a ball from a table to hit a target on the ground. In Experiments 1 and 2, the virtual scene was presented on a computer monitor, and, in Experiment 3, it was projected by using a video projector so that the vertical and horizontal dimensions and the spatial location of the VE corresponded to the real-world dimensions. Results indicate that action knowledge is accessible even in a nonimmersive VE, but also suggest that the need to recalibrate perceptual-motor mappings constrains the accessibility of this kind of intuitive knowledge.     

The consequences of virtual embodiment for the mental representation of proximity

There is evidence that knowledge about space will reflect the details of how that space is experienced and how people interact with it. In two experiments we demonstrate that memory for items is spatially structured after their locations were learnt in a desktop virtual environment (DVE). The structure was measured using interitem priming of recognition. By comparison in Experiment 2, after the same layout had been learnt using a map display, there was no evidence of spatial structuring in memory. It is concluded that the limited view of space afforded by navigation through an environment, as contrasted with the overview afforded by a map, explains the observed differences in the spatial structuring of interitem associations. Navigation through an environment leads to spatial structuring in memory whereas using a map does not.     

A SOCIAL ECOLOGY OF HYPERACTIVE BOYS: MEDICATION EFFECTS IN STRUCTURED CLASSROOM ENVIRONMENTS

Hyperactive boys on methlyphenidate (Ritalin), hyperactive boys on placebo, and comparison boys were observed in quasi-naturalistic classroom settings. Ambient stimulation (quiet versus noisy conditions) and source of regulation (self-paced versus other-paced activities) were varied in a 2 × 2 design. Compared to their peers, hyperactive boys on placebo showed lower rates of task attention and higher rates of gross motor movement, regular and negative verbalization, noise-making, physical contact, social initiation, disruption, and acts that were perceived as energetic, inappropriate, or unexpected. Self-paced activities resulted in increased rates of verbalization, social initiation, and high-energy episodes. High ambient noise levels reduced task attention and increased the rates of many other behaviors including verbalization, physical contact, gross motor movement, and high-energy acts. Medication-by-situation interactions emerged for both classroom dimensions, with hyperactive boys on placebo being readily distinguishable from their peers under some classroom conditions and indistinguishable under other conditions. Moderate relationships were found between teacher ratings and many individual behavior categories. Discussion focused on (a) the merits and limitations of a social ecological research perspective, and (b) the implications of these findings for the design of intervention strategies.     

Call for Research on Bystander Intervention to Prevent Sexual Violence: The Role of Campus Environments

An important next step for the field is to determine what setting‐level factors beyond the individual are critical to fostering campus environments that support pro‐social, helpful bystander intervention action to prevent sexual violence. Therefore, the purpose of this paper is to provide a research agenda to investigate key areas of the campus environment and their potential influence on bystander intervention. To create the research agenda, a number of steps were followed including: (1) systematically reviewing the larger bystander literature to identify key environmental areas, (2) assessing what research is available specific to college campuses and sexual assault in each of these areas, and (3) outlining future research to address each of these areas on college campuses and determine their applicability to sexual violence situations. Five main groups of factors were found to influence bystander intervention beyond the individual, group and situational levels, including: social norms, sense of community, pro‐social modeling, policies, and the physical environment. Certain areas of research on environmental influences on bystander intervention are more developed such as social norms, with little research on areas such as policies and the physical environment. However, further research is needed in each of the identified five areas to help identify how college campuses can support bystander intervention.     

影响再次侵犯的实验研究:报复、惩罚、沉默、还是宽恕?

本研究从侵犯者角度出发,探讨受害者不同应对策略是否会影响侵犯者的再次侵犯。研究1采用囚徒困境范式,考察62名大学生应对策略和报复机会对再次侵犯的影响。研究2采用故事情境法,考察227名被试应对策略、年龄对悔改动机和再次侵犯的影响。结果发现,应对策略、年龄的主效应显著,二者交互作用显著,被试年龄越大对报复者侵犯的可能性越低。启示我国目前仍应以报应性司法模式为主,可在青少年群体尝试恢复性司法。。     

Exposure to Violence and Attitudes Towards Transitional Justice

Transitional justice has emerged to address victims' needs as a means of restoring relations broken by violence. Yet we know little about victims' attitudes towards different transitional justice mechanisms. Why do some victims prioritize retributive justice while others favor other forms of dealing with the violent past? What determines victims' attitudes towards transitional justice policies? To address these questions, we offer a new theoretical framework that draws upon recent insights from the field of evolutionary psychology and links both war exposure and postwar environments to transitional justice preferences. We argue that both past experiences of wartime violence and present‐day social interdependence with perpetrators impact transitional justice preferences, but in divergent ways (resulting in greater support for retributive vs. restorative justice measures, respectively). To test our framework, we rely upon a 2013 representative survey of 1,007 respondents focusing on general population attitudes towards transitional justice in Bosnia two decades after the implementation of the Dayton Accords. Specifically, we examine the impact of displacement, return to prewar homes, loss of property, loss of a loved one, physical injury, imprisonment, and torture on attitudes towards transitional justice. On the whole, our findings confirm our two main hypotheses: Exposure to direct violence and losses is associated with more support for retributive justice measures, while greater present‐day interdependence with perpetrators is associated with more support for restorative justice measures. While acknowledging the legacy of wartime violence, we highlight the importance of the postwar context and institutional mechanisms that support victims in reconstructing their lives.     

Community service for misdemeanours in Accra: Preferences of offenders,victims, judiciary,and community members

Taking religiosity into account, the study explored preferences for community service sentencing by victims, offenders, judiciary, and community members from Accra, Ghana. One hundred and ninety respondents were sampled (females = 38.42%, offenders = 5.26%, victims = 58.95%, law enforcement = 10.52%, members of the Judiciary = 4.74%, and general community members = 65.26%). They responded to the Attitude Towards Community Service Questionnaire, and the data were analysed utilising ANOVA between group difference tests. Offenders expressed a higher preference for community sentencing than victims and members of the judiciary. Religion aligned participants supported community sentencing. Community sentencing seems a preferred sentencing option by a cross section of Ghanaian community members for adult non-violent offenders.     

从恢复体验到地方依恋:环境偏好与居住时长的作用

探究源自环境的恢复体验(如,放松、平静等)对居住者地方依恋(包括地方依赖和地方认同两个维度)的预测作用,并分析其中的内在过程与情境条件。采用问卷研究法(N=410),结果发现:(1)恢复体验能显著正向预测个体地方依恋;(2)环境偏好在恢复体验与地方依恋之间起完全中介作用;(3)居住时长调节环境偏好与地方依恋(主要是地方认同)之间的关系。研究将有助于探寻环境心理学视角下的压力管理与城市管理协同路径。     

Autochthony through self-organization: Interactivism and emergence in a virtual environment

In this paper we take an interactivist perspective on the computer-mediated classroom, and explore the autopoietic teaching approach in the context of emergence of diversity in the classroom. The POPSICLE (Patterns in Orientation: Pattern-Aided Simulated Interaction Context-Learning Experiment) is presented and discussed, as well as its multiple consequences. POPSICLE is a study of learning in human subjects, as well as of interaction and transfer of knowledge between subjects in a collaborative environment.
