Social Attention and Mentalizing During Puberty and Risk for Social Anxiety

项目概要/摘要 大约9.1%的美国青少年（11.2%的女孩，7.0%的男孩）经历社交焦虑，1一种障碍 特点是难以和害怕社会交往。2同伴的社会交往是 社会情感和神经发育的影响。对社会交往很重要的过程， 包括社会关注和心理化，解释他人意图和情绪的能力，3是在 在青春期的流动，4，5与青春期发挥特别有影响力的作用，在重新定位注意力， 同龄人6和心智网络7和行为的发展。青春期可能是一个敏感时期 在此期间，社会关注和心理化过程的整合可能会巩固或改变轨迹， 特别是在已经处于社交焦虑高风险的个体中。当前许可 将利用两个独立的样本（一个横截面和一个纵向）来检查青春期作为一个 社会注意力和心智化过程（行为和神经）整合的敏感期 和社交焦虑的风险。研究1将使用在11岁和12岁青少年中收集的横断面数据。 青少年将完成功能磁共振成像心智化任务，并参与社会互动，而移动的眼睛- 跟踪数据被收集。社会互动将被编码为心理化语言/行为。 青少年将被评估，并自我报告，青春期状态。在研究1中，我将把青春期作为一个 自然主义的社会关注和自发的心理化（目标1）的整合的敏感期。研究2 将使用来自完整数据集的纵向数据。青少年被评估为恐惧的气质， 社交焦虑因子，2岁时为9。青少年参与社会互动和自我报告的青春期 12年的地位。参与者在15岁时自我报告社交焦虑。在研究1中，社会互动将 被编码为心智化语言/行为。通过研究2，我将研究青春期相关的纵向 自发心理化、恐惧性气质与社交焦虑的关系（目的2）。发现将 提供有关青春期在社会情绪发展中的作用和社交焦虑风险的信息。 目前的研究是设计一个综合培训计划，将准备研究金申请人， 未来的职业是发展社会神经科学家三个首要的培训目标是：1）先进的 自然神经科学方法论、数据分析和心理化培训。2)获得概念和 青春期的方法学培训和相关的精神病理学风险。3)高级培训和专业 为独立的研究生涯做准备。这些培训目标将有效地准备 申请人在成为发展社会神经科学家的理想职业道路上的下一步 并为未来研究社会关注的共同发展奠定基础 和心理化是社交焦虑风险的潜在机制。

Project Summary/Abstract Approximately 9.1% of US adolescents (11.2% girls, 7.0% boys) experience social anxiety,1 a disorder characterized by difficulty with and fear of social interactions.2 Peer social interactions are the building blocks of socioemotional and neural development during adolescence. Processes important for social interaction, including social attention and mentalizing, the ability to interpret the intentions and emotions of others,3 are in flux during adolescence,4,5 with puberty playing a particularly influential role in reorienting attention towards peers6 and the development of the mentalizing network7 and behavior.8 Puberty may be a sensitive period during which the integration of social attention and mentalizing processes could solidify or alter trajectories towards social anxiety, particularly in individuals already at elevated risk for social anxiety. The current grant will capitalize on two separate samples (one cross-sectional and one longitudinal) to examine puberty as a sensitive period for the integration of social attention and mentalizing processes (both behavioral and neural) and risk for social anxiety. Study 1 will use cross-sectional data, collected in 11- and 12-year-old adolescents. Adolescents will complete an fMRI mentalizing task and participate in a social interaction while mobile eye- tracking data are collected. The social interaction will be coded for mentalizing language/behaviors. Adolescents will be assessed for, and self-report, pubertal status. Through Study 1, I will examine puberty as a sensitive period for the integration of naturalistic social attention and spontaneous mentalizing (Aim 1). Study 2 will use longitudinal data from a completed dataset. Adolescents were assessed for fearful temperament, a risk factor for social anxiety,9 at 2 years. Adolescents participated in a social interaction and self-reported pubertal status at 12 years. Participants self-reported social anxiety at 15 years. As in Study 1, the social interaction will be coded for mentalizing language/behaviors. Through Study 2, I will examine puberty-linked longitudinal relations between spontaneous mentalizing, fearful temperament and social anxiety (Aim 2). Findings will provide information about the role of puberty in socioemotional development and risk for social anxiety. The current study is designed with an integrated training plan that will prepare the fellowship applicant for a future career as a developmental social neuroscientist. The three overarching training goals are: 1) Advanced training in naturalistic neuroscience methodology and data analysis and mentalizing. 2) Obtain conceptual and methodological training in puberty and associated psychopathology risk. 3) Advance training and professional development in preparation for an independent research career. These training goals will effectively prepare the applicant for the next steps in the desired career path of becoming a developmental social neuroscientist as well as lay the foundation for a future research program examining the co-development of social attention and mentalizing as a potential mechanism underlying social anxiety risk.
