Kids' brains may hold clues to future criminals – The Chart - CNN.com BlogsExperiments by Raine have found that by looking at the brains of 3-year-old children, scientists could already see signs of potential trouble in the future. Raine discussed this research Monday at the American Association for the Advancement of Science annual meeting in Washington.
Those who had poor amygdala function at that time were more likely to become criminal offenders later in life, in the 20-year time span during which the scientists followed them. The amygdala is an almond-shaped brain area associated with fear, and it appears that a trend among offenders is that fear conditioning is impaired. Researchers did not directly measure amygdala function in a brain scanner, but used the children's fear responses to an anticipated punishment as a proxy for that.
In fact, adult psychopaths appear to have an 18% reduction of the volume of the amygdala compared with non-psychopaths. This difference might explain why psychopaths lack remorse, fear and guilt.
