Walden Dissertations and Doctoral Studies
A genetic polymorphism found in the upstream region of the monoamine oxidase A (MAOA) gene upstream variable number tandem repeat (u VNTR) has been shown to have an influence on aggression with mixed results.

The conceptual framework was based on the biosocial model of antisocial behavior that indicates genes can influence aggressive behaviors with or without environmental influences. Data (N = 2506) from the National Longitudinal Adolescents and Adult …

The current study examined the scale of violence through measures of frequency and duration, correlated with a single-parent upbringing among male serial killers who operated alone in the United States. In a nonexperimental, cross-sectional design, I used a multivariate analysis of variance to compare 85 male serial killers raised by a single parent with 85 male …
