offender desistance Flashcards
how does age affect desistance?
- decline in physical strength, lost contact with antisocial peers, maturation
- learning to evade detection, ongoing antisocial behaviour that does lead to arrest
Physiological changes
dopamine receptors decrease with age, norepinephrine decreases with age, testosterone is high in adolescence
neurobiology (testosterone, receptor genes) Shaal et al., 1996
high testosterone linked with ratings of toughness and leadership, but not aggression
-certain dopamine receptor genes DRD2&DRD4 have negative relationship with delinquency abstention for males only
the genius-age link (Kanazawa, 2003)
- scientific productivity fades rapidly with age
- most sig contributors occur during the five years around 30
- women did not have the same curve as men
evolutionary process of aggression
competitive effort
-leads to productivity of different kinds, increases ones reproductive success, maybe men find it evolutionary to gain mates and children
different trajectories within the curve
- around 70% follow the curve (Blokland et al. 2005)
- 50% are in the process of desisting, initial severity level and number of offences important (wiesner & Capaldi, 2003)
- age of onset a predictor in how long careers last, still finish at the same age (Ezell 2007)
desistance and substance abuse
substance abuse accelerates antisocial behaviour and hinders desistance
- substance abuse and crime tend to increase and decrease together
- substance abstinence does not guarantee crime abstinence
