PSYCHOPHYSIOLOGY IN VIOLENCE--RISK AND PROTECTION

这项拟议中的研究旨在揭示青少年的生理和暴力行为之间的预测关系，这些青少年是和不是处于社会风险中。自主神经以及皮质的措施将在基线，并在应对压力和挑战任务进行检查。这些措施将在青少年中进行比较，这些青少年既有社会风险因素，也有生物风险因素，只有生物风险因素，只有社会风险因素，或对照组。据推测，没有社会危险因素但生理唤醒水平很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，它表明，青少年与社会风险因素，但与高水平的觉醒将不太可能成为暴力的危险科目与正常水平的觉醒。这项研究将允许检查青少年谁是在高社会风险，但通过生理保护免受暴力行为。因此，对生物、社会和心理因素（如冲动性）之间的相互作用的研究将成为可能。这些措施将对生物学在使青少年处于暴力行为风险中所起的作用以及保护他们免于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.
