Abstract/Description
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...
Show moreMany 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.

Narcissism, adjustment, and target-specific aggression in preadolescence
Title
Narcissism, adjustment, and target-specific aggression in preadolescence: a test of the self-image failure hypothesis.
Creator
Pauletti, Rachel E., Charles E. Schmidt College of Science, Department of Psychology
Abstract/Description
This study examined the consequences of self-image failure among narcissistic children. It was hypothesized that narcissistic children who perceive themselves as falling short of their hoped-for grandiose self (e.g., whose self-esteem is low) would not only increase over time in general aggression and decrease prosocial behavior, but also increase in the tendency to direct aggression specifically toward more socially successful peers (i.e., their putative rivals for social status)....
Show moreThis study examined the consequences of self-image failure among narcissistic children. It was hypothesized that narcissistic children who perceive themselves as falling short of their hoped-for grandiose self (e.g., whose self-esteem is low) would not only increase over time in general aggression and decrease prosocial behavior, but also increase in the tendency to direct aggression specifically toward more socially successful peers (i.e., their putative rivals for social status). Participants were 195 (101 boys) fourth through seventh-graders who were tested in both the fall and the spring of a school year. Results yielded some support for the hypotheses. Narcissism combined with low self-appraisals of the real self to predict decreases in prosocial behavior and increased aggression toward popular and attractive peers. These findings not only provide longitudinal evidence for the self-image failure hypothesis but also underscore the importance of a target-specific approach to investigating children's aggression.
