PSYCHOPHYSIOLOGY IN VIOLENCE--RISK AND PROTECTION

这项提议的研究旨在揭示有或没有社会风险的青少年的生理和暴力行为之间的预测关系。自主神经和皮质测量将在基线和应激源和挑战任务的反应中进行检查。这些措施将在有社会和生物风险因素的青少年群体中进行比较，只有生物风险因素，只有社会风险因素，或对照。假设没有社会风险因素但生理唤醒非常低的青少年比正常唤醒水平的受试者更容易变得暴力。此外，具有社会风险因素但具有高唤醒水平的青少年不会像具有正常唤醒水平的高危受试者那样容易变得暴力。这项研究将允许检查那些处于高社会风险但通过生理保护免受暴力行为的青少年。因此，研究生物、社会和心理因素（如冲动）之间的相互作用将成为可能。这些措施将对生物学在将青少年置于暴力行为风险中所起的作用以及保护他们不发展这种行为的能力产生影响。

The proposed study aims to uncover the predictive relationship between physiology and violent behavior in adolescents who are, and are not at social risk. Autonomic as well as cortical measures will be examined both at baseline, and in response to stressor and challenge tasks. These measures will be compared in groups of adolescents who have both social and biological risk factors, biological only, social only, or controls. It is hypothesized that adolescents with no social risk factors but very low physiological arousal will be more likely to become violent than subjects with normal levels of arousal. Additionally, it is suggested that adolescents with social risk factors but with high levels of arousal will not be as likely to become violent as at-risk subjects with normal levels of arousal. This study will allow for the examination of adolescents who are at high social risk but are protected from violent behavior through physiology. The examination of the interaction between biological, social, and psychological factors, such as impulsivity, will thus be possible. These measures will have implications for the role biology plays in putting adolescents at risk for violent behavior as well as its ability to protect them from developing this behavior.
