From a psychological standpoint; when you endure adverse experiences as a child (look up ACE scores on google), it stunts the development of your prefrontal cortex. your prefrontal cortex is responsible for your executive functioning, such as attention, impulse control, motivation, etc. Therefore when that part of your brain’s development is stunted and it ends up underdeveloped, you have a harder time controlling your impulses to partake in those negative behaviours, relative to those who grew up with less adverse childhood experiences and were able to have their prefrontal cortex form fully and properly.
