Standard demographic assessments have been used to try to predict which felons will commit crimes after prison release. A recent study using functional magnetic resonance imaging has examined the potential applicability of brain imaging for this purpose — specifically, whether anterior cingulate cortex (ACC) activity during a specific functional task (go/no-go impulse-control task) would predict subsequent re-arrest in released criminals.
The 96 male prisoners (age range, 20–52) from two state correctional facilities were evaluated at prison release; they were also assessed for other possibly relevant factors (e.g., psychopathy, alcohol or drug abuse/dependence). Mean follow-up was 34.5 months. Lower ACC activity (measured in units) correspo…
