- Neural & Hormonal Mechanisms in Aggression
- Neural mechanisms in aggression
- Limbic System
- AO3:CONTRADICTORY; orbital frontal cortex also involed; more complex.
- SUPPORT: Raine et al: Asymetric hippocampus=>criminals who were caught; more impulsive; Asy. Hippo. linked with aggression
- Cingulate gyrus, hypothalamus,fornix, amygdala=> humans/non humans animals; how respond to environmental threats
- AO3:CONTRADICTORY; orbital frontal cortex also involed; more complex.
- Serotonin(Inhibitory): Heavy amounts prevents aggression
- Lower than normal=Aggression
- Dolan et al: Postive correlation between testostorone levels & aggressive behaviour; male offenders.
- Mann et al: 33 healthy participants; given dexfenfluramine(reduces seratonin levels). Found reduced levels led to aggression
- Birman et al: gave particpants placebo or drug which enhanced seratonin; toke part in game which they give shocks.Ones who toke drugs had significantly less intense shocks.
- AO3:REDUCTIONISM;ignores social factors in aggression. Bandura; social learning important factor influence on the aggressive behaviour
- Zimbardo; deindividuatioin increase aggressive behaviour in situations where personal responsibility is diminished.
- Lower than normal=Aggression
- Limbic System
- Hormonal Mechanisms in aggression
- Testosterone
- Dolan; positive correlation; test. levels & aggression in sample of 60 male offenders
- SUPPORT:Archer meta-analysis of five studies; positive correlation between levels of testosterone and aggression
- Testosterone
