"...incarceration or institutionalization can delay emotional growth" I once read a criminal profile of a serial killer made by a forensic psychologist. The forensic psychologist wrote the following: "Age is difficult to predict because this analysis is a measure of an offender’s emotional age as opposed to his chronological age. Factors such as incarceration or institutionalization can delay the emotional growth of an individual." This seems counterintuitive to me. I have always thought that hardship makes a person more mature. The forensic psychologist was profiling a criminal in America. American prisons are generally fairly rough (violent) places. Incarceration in an American prison would certainly seem like a hardship to me. To me, I would have thought that incarceration would tend to make a person more mature rather than more immature (if it had any effect on a person's maturity level). The forensic psychologist however said that incarceration can delay the emotional growth of an individual. Do you people agree with the psychologist that incarceration can delay the emotional growth of an individual? Has anyone ever researched this? How or why would incarceration delay the emotional growth of an individual?
