The prevalence of anxiety symptoms in children and adolescents has doubled since before the COVID pandemic.
Violent video games may increase agitation in young children, but the agitation does not translate into violence against other people, researchers say.
Lower cholesterol levels may put people with schizophrenia at higher risk for violent behaviors, including self-harm and suicide. Researchers say lower cholesterol levels make brain cells less sensitive to serotonin, increasing symptoms of depression, impulsivity, and aggression.
A comparative review of 324 global research papers concludes narcissism is a risk factor for aggression and violent behaviors. The results were similar, regardless of age, gender, education level, or country of residence.
While many people freeze while witnessing a violent event, researchers say nine times out of ten, at least one person will intervene to help the victim.
Experiencing bullying and aggression as a teen or young adult increases violent ideations, including thoughts of harming or killing others, a new study reports.
People with strong moral and political convictions who saw images of protestors congruent to their own views showed activation in the brain's reward system. The study suggests violent acts in political protests can arise as a desire to act morally, rather than from bad intentions.
Strengthened amygdala pathways increase aggression in those who have experienced trauma. The findings could lead to new treatments for PTSD.
While psychopathy is generally associated with antisocial behaviors, many with the personality trait develop successful careers. A new study supports a novel model of psychopathy which runs contradictory to existing models of the disorder, focusing on the strengths associated with psychopathy, rather than just the deficits. Researchers found higher initial psychopathy was associated with a steeper increase of general inhibitory control and the inhibition of aggression over time. The effect was magnified among those who were "successful."
Exposure to violence and childhood adversity has a negative effect on the developing brain. Neuroimaging reveals adolescents who experienced adversity and violence as children had reduced connectivity between the amygdala and the prefrontal cortex. However, social support may act as a buffer and reduce the negative effects of early life stress.
Scenes of justified and unjustified violence in movies activate different areas of the adolescent brain. Unjustified violence activates the lateral orbital frontal cortex, while scenes where violence appears justified, activates the ventromedial prefrontal cortex.
