性别、寻路策略与导航方式对寻路行为的影响

本研究探讨了两种寻路策略与三种导航方式对寻路行为绩效的影响并分析了该效应的性别差异。实验被试120名, 实验结果显示：在VR迷宫场景中寻路, 对男性而言, 定向策略的使用情况是影响导航方式绩效的重要因素。对不擅长使用定向策略的男性而言, 标志导航最佳, 标志与YAH地图并存时次之, YAH地图导航最差。其中, 标志导航与YAH地图导航绩效差异显著。而对擅长使用定向策略的男性而言, 导航方式的类型对寻路绩效的影响不显著。导航方式的类型对女性寻路影响显著, 其中, 标志导航最佳, 标志与YAH地图并存时次之, YAH地图导航最差。该研究结果可为导航支持系统的界面设计提供依据。     

Peer Contagion in Interventions for Children and Adolescents: Moving Towards an Understanding of the Ecology and Dynamics of Change

The influence of deviant peers on youth behavior is of growing concern, both in naturally occurring peer interactions and in interventions that might inadvertently exacerbate deviant development. The focus of this special issue is on understanding the moderating and mediating variables that account for peer contagion effects in interventions for youth. This set of nine innovative papers moves the field forward on three fronts: (1) Broadening the empirical basis for understanding the conditions under which peer contagion is more or less likely (that is, moderators of effects); (2) Identifying mechanisms that might account for peer contagion effects (mediators); and (3) Forging the methodological rigor that is needed to study peer contagion effects within the context of intervention trials. We propose an ecological framework for disentangling the effects of individuals, group interactions, and program contexts in understanding peer contagion effects. Finally, we suggest methodological enhancements to study peer contagion in intervention trials.     

Triple P-Positive Parenting Program: Towards an Empirically Validated Multilevel Parenting and Family Support Strategy for the Prevention of Behavior and Emotional Problems in Children

This paper outlines the theoretical and empirical foundations of a unique multilevel parenting and family support strategy designed to reduce the prevalence of behavioral and emotional problems in preadolescent children. The program known as Triple P-Positive Parenting Program is a multilevel system of family intervention, which provides five levels of intervention of increasing strength. These interventions include a universal population-level media information campaign targeting all parents, two levels of brief primary care consultations targeting mild behavior problems, and two more intensive parent training and family intervention programs for children at risk for more severe behavioral problems. The program aims to determine the minimally sufficient intervention a parent requires in order to deflect a child away from a trajectory towards more serious problems. The self-regulation of parental skill is a central construct in the program. The program uses flexible delivery modalities (including individual face-to-face, group, telephone assisted, and self-directed programs) to tailor the strength of the intervention to the requirements of individual families. Its multidisciplinary, preventive and community-wide focus gives the program wide reach, permitting the targeting of destigmatized access points through primary care services for families who are reluctant to participate in parenting skills programs. The available empirical evidence supporting the efficacy of the program is discussed and its implications for research on dissemination are discussed.
