Document Summary

Part 1: 20 multiple choice (1 mark each) If you know the name of the theorist is write it down. If you know the concept write it down. Dna - 99% -> shared by all humans. Concordance rate: the degree to which related pairs exhibit a particular trait, behaviour, or characteristic. Stronger for adult criminality (effect of environment stronger on juvenile crime) > addressed enviornment issue of earlier twin studies. > compared traits of twin adopted by non-family members with those of their original (biolgocial) parents. > high concordance between adopted twins and their biolgical parents = more likely to be inherited. Higher level of anti-social/criminal behaviour for adoptees whose biological parents were criminal. In most cases this, this relationship has been demonstrated only for non-violent crime. Amino acids + enzymes = neurotransmitters - nerve cells communicate through messengers (neurotransmitters) -> after message has been received, neurotransmitter is broken down into metabolite. More likely to suffer from anti-social personality disorder.
