One discussion question I often ask my students is how early do they think the abnormal wiring of psychopaths could be detected by brain imaging technology. And then my follow-up question is IF we can predict that certain brain wiring patterns predict psychopathic behaviors by age 6,what type of action might be appropriate, if any?
I have read a fair amount about the early life experiences of psychopaths and they usually have experienced very high levels of violence as well as very low levels of empathy. So might it not be a plausible hypothesis that they have habituated to stress as well as to gruesome, violent images. Just BTW, let us not forget that all of our brains are wired differently relative to how much we have been exposed to music, language, motor activities, etc. Our brain is capable of making new neural connections throughout life but nothing like during our early years, dang it.
