| Summary: | Many cardiovascular psychophysiological studies have found evidence of lower arousal states in aggressive individuals and hyper-arousal states in individuals exposed to chronic stress. However, most of these studies have relied on clinical diagnoses or self-reports to identify aggressive and victimized individuals. The present study used peer nominations to identify aggressive, victimized, and non-aggressive or victimized adolescents (mean age = 12.09 yrs.) to examine if any psychophysiological differences exist during resting and startle conditions. ANOVAs revealed that high aggressive/low victimized adolescents had a lower resting heart period/rate compared to high victimized/low aggressive adolescents. Further analyses revealed a statistical trend of lower resting heart period variability in high victimized/low aggressive individuals compared to non-aggressive non-victimized controls. Due to evidence suggesting that individuals with high self-reported empathy display less aggression, empathy as a moderator for aggression was investigated. Although gender differences w3ere found across measures, empathy ws not found to moderate aggression. === by Christopher Aults. === Thesis (M.A.)--Florida Atlantic University, 2012. === Includes bibliography. === Mode of access: World Wide Web. === System requirements: Adobe Reader.
