DESCRIPTION (provided by applicant): Exposure to family conflict has been linked with later deficits in social functioning, and social difficulties are implicated in a variety of psychological disorders. The proposed study seeks to inform research into the causes and consequences of social vulnerability by identifying neural markers of maladaptive social processing among adolescents. We test a theoretical model linking family conflict to social behavior and psychological symptoms in a diverse sample of youth in late adolescence (ages 17-19) whose exposure to family conflict has been tracked as part of an eight-year, five-wave longitudinal study. We focus in particular to the neural correlates of reactivity to social exclusion, a construct we label social exclusion reactivity (SER). We will introduce participants to two functional neuroimaging (fMRI) tasks designed to assess neural SER (NSER): the Cyberball paradigm (Williams & Jarvis, 2006), a computer game that elicits feelings of social exclusion, and the Social Pain Task (Immordino-Yang, McColI, Damasio and Damasio, in press), in which youth are presented with vignettes showing others being socially excluded or rejected. Both neuroimaging tasks have been linked with increased activation in brain regions associated with distress and pain processing. We expect youth with past exposure to family conflict to display greater activation in these "distress" areas, as well as diminished ability to manage that distress by recruiting areas of the prefrontal cortex that have been shown to help down regulate social distress in previous studies. We also expect these neural correlates of SER to be associated with youths' psychological symptoms and with their everyday social behavior as measured during a 14-day daily diary study. By integrating these two neuroimaging protocols with longitudinal data on family conflict from multiple reporters and ecologically valid data on adolescents' real-life social interactions, the proposed project should offer an unprecedented depth of perspective on social functioning at a pivotal developmental stage. PUBLIC HEALTH RELEVANCE: Conflictual family environments and a lack of social integration have both been linked with increased mental and physical health risks across the lifespan. Research that identifies markers of social vulnerability in young people, at the level of nonconscious cognitive and affective processing, can inform understanding of psychological disorders related to social functioning and the development of interventions targeting youth at risk. Important, enduring relationships are often formed during the transition from adolescence to adulthood, while psychological symptoms may begin to emerge, warranting a focus on social difficulty during this stage of life.

描述(由申请人提供)：暴露在家庭冲突中与后来的社会功能缺陷有关，社会困难与各种心理障碍有关。这项拟议的研究试图通过确定青少年社会处理不良的神经标志物，为社会脆弱性的原因和后果的研究提供信息。我们测试了一个理论模型，将家庭冲突与社会行为和心理症状联系起来，对青春期后期(17-19岁)的不同样本进行了调查，作为一项为期八年的五波纵向研究的一部分，他们对家庭冲突的暴露进行了跟踪。我们特别关注反应性与社会排斥的神经关联，我们将这种结构称为社会排斥反应性(SER)。我们将向参与者介绍两个旨在评估神经SER(NSER)的功能神经成像(FMRI)任务：Cyberball范式(Williams&Jarvis，2006)，这是一种引发社会排斥感的电脑游戏，以及社交疼痛任务(Immomeo-Yang，McColi，Damasio和Damasio，正在出版中)，在该任务中，向年轻人呈现显示其他人被社会排斥或拒绝的小插图。这两项神经成像任务都与与痛苦和疼痛处理相关的大脑区域的激活增加有关。我们预计，过去经历过家庭冲突的年轻人会在这些“痛苦”区域表现出更大的激活，同时通过招募前额叶皮质区域来管理这种痛苦的能力减弱，这些区域在以前的研究中被证明有助于下调社会痛苦。我们还希望SER的这些神经关联与青少年的心理症状和他们的日常社会行为有关，这是在14天的每日日记研究中测量的。通过将这两种神经成像协议与来自多个记者的关于家庭冲突的纵向数据以及关于青少年现实生活中社交互动的生态有效数据相结合，拟议的项目应该为关键发展阶段的社会功能提供前所未有的深度视角。 公共卫生相关性：冲突的家庭环境和缺乏社会融合都与一生中心理和身体健康风险的增加有关。在无意识的认知和情感处理水平上确定青年社会脆弱性的标志的研究，可以帮助人们了解与社会功能有关的心理障碍，并制定针对高危青年的干预措施。重要的是，持久的关系通常是在从青春期到成年期的过渡过程中形成的，而心理症状可能会开始出现，这就需要在人生的这个阶段关注社交困难。
