The applicant requests five years of funding through the Mentored Career Development Award (K23) for training in psychophysiological methods to examine the effects of physical abuse and domestic violence on children. The candidate's ultimate goal is to integrate this training with her previous experience in observational approaches. The candidate will also gain experience in the ethical and methodological issues involved in conducting research with samples of abused and neglected children. Training includes coursework and close mentoring with experts in research on child abuse, domestic violence, psychophysiology, aggression,, measurement design, and multi-variate data analysis. The primary goal of the research plan is to test competing models for the role of autonomic nervous system (ANS) activity in the link between family violence and two different types of adolescent aggression: proactive aggression, which is unemotional and instrumental, and reactive aggression, which is emotional and defensive. The trauma of family violence may sensitize children, causing increased ANS activity to subsequent conflict and thereby increased reactive aggression. Alternatively, prolonged exposure to family violence may cause suppressed ANS activity and thus increased proactive aggression. Still another possibility is that family violence does not affect ANS activity, but that ANS response moderates the effect of family violence on adolescent aggression. Data collection will be part of a larger R01 grant examining the effects of abuse and neglect on adolescent development. The sample will include 210 abused adolescents identified by the Los Angeles Department of Child and Family Services and 210 comparison children. ANS arousal and reactivity to conflict stimuli will measured, and information regarding aggression and family violence histories will be obtained. The first year of the award will be devoted to developing stimuli for the psychophysiological assessments and to refining measures of proactive and reactive aggression. The subsequent years will be devoted to conducting the substantive research project.

申请人通过辅导职业发展奖（K23）申请五年的资金，用于心理生理学方法的培训，以研究身体虐待和家庭暴力对儿童的影响。候选人的最终目标是将这种培训与她以前在观察方法方面的经验相结合。候选人还将获得与虐待和忽视儿童的样本进行研究所涉及的道德和方法问题的经验。培训包括课程和与虐待儿童，家庭暴力，心理生理学，侵略，测量设计和多变量数据分析研究专家的密切指导。研究计划的主要目标是测试自主神经系统（ANS）活动在家庭暴力和两种不同类型的青少年攻击之间的联系中的作用的竞争模型：主动攻击，这是非情绪化和工具性的，以及反应性攻击，这是情绪化和防御性的。家庭暴力的创伤可能会使儿童敏感，导致随后的冲突增加ANS活动，从而增加反应性攻击。或者，长期暴露于家庭暴力可能会导致抑制ANS活动，从而增加主动攻击。还有一种可能性是，家庭暴力不影响ANS活动，但ANS反应缓和家庭暴力对青少年攻击的影响。数据收集将是一个更大的R01赠款的一部分，审查虐待和忽视对青少年发展的影响。样本将包括由洛杉矶儿童和家庭服务部确定的210名受虐待青少年和210名对照儿童。将测量对冲突刺激的ANS唤醒和反应，并获得关于攻击和家庭暴力史的信息。该奖项的第一年将致力于开发心理生理评估的刺激因素，并改进主动和被动攻击的措施。随后几年将致力于开展实质性研究项目。
