BRAIN DEVELOPMENT DURING ADOLESCENCE?
• Increase in dopaminergic activity (reward sensitivity) • Prefrontal cortex continues to develop until mid-20s (plan & control behavior) • Synaptic pruning (makes brain more efficient)
T/F: In general, people’s offending declines over time
TRUE
- Due to maturing
- Psychosocial maturity accounts for 34% of the of drop (e.g., better able to control impulses)

Moffits developmental taxonomy
Different types of offenders
1) life-course persistent
2) adolescent-onset
3) child-limited
4) adult-onset
life-course persistent starts
early, during childhood
life-course persistent cause is from
Neuropsychological deficits (e.g., impulsivity) plus unsupportive environment
life-course persistent duration
- Hypothesized to be lifelong offenders
• But some research indicates that most offenders stop by mid-adulthood
how common are life-course persistent offenders?
Rare, most adolescents who offend are not lifelong offenders
ADOLESCENT ONSET OFFENDERS starts at
adolescence
ADOLESCENT ONSET OFFENDERS cause
Maturity gap + delinquent peers
• Sexually mature but aren’t recognized as such
• Offending helps acquire mature status
ADOLESCENT ONSET OFFENDERS duration
Hypothesized to stop in adulthood
• However, research has found that still offending at age 25 but less than life course
how common is ADOLESCENT ONSET OFFENDERS
Common/normative
WHY DIDN’T THE ADOLESCENT-ONSET OFFENDERS STOP BY
20?
- Maybe desistance might be delayed as society has evolved?
- In past: age 18 – moved out, got a job, got married
- Now: these things happen later; “emerging adulthood” – 18-25 years old
- Maybe experimenting with offending during adolescence has costs
- Some become ensnared (trapped in the crimes they committed as adolescents)
