What did Raine's study demonstrate about the relationship between brain function and violent behavior?

• A. It demonstrated that only environmental factors influence behavior
• B. It highlighted significant brain regions associated with violence
• C. It showed no relationship between violence and brain function
• D. Violence is completely genetic with no environmental influence

Answer: (B)

Raine's study provided significant insights into the neurological underpinnings of violent behavior by identifying specific brain regions that are associated with such behavior. Through the use of brain imaging techniques, the research focused on structures like the prefrontal cortex and the amygdala, which are known to be involved in impulse control, decision-making, and emotional regulation. The findings indicated that abnormalities or dysfunctions in these areas could be linked to an increased propensity for violence.

Thus, the correct answer underscores the connection between brain structure and function and violent behavior, illustrating the biological aspect of aggression. This relationship emphasizes the complexity of violent behavior, which arises from an interplay of both biological and environmental factors, rather than suggesting that violence is solely determined by environmental influences or genetic predispositions alone.
