Neurocognitive deficits related to poor decision making in people behind bars.

Using a novel quantitative model of repeated choice behavior, we investigated the cognitive processes of criminal offenders incarcerated for various crimes. Eighty-one criminals, including violent offenders, drug and sex offenders, drivers operating a vehicle while impaired, and 18 matched controls were tested. The results were also contrasted with those obtained from neurological patients with focal brain lesions in the orbitofrontal cortex and from drug abusers.

Prison-based research has been limited due to concern that prisoners may represent a vulnerable population secondary to possible coercion and limited capacity for voluntary informed consent. This study was designed to assess decisional capacity and susceptibility to coercion in prison research subjects. Subjects were 30 mentally ill prisoners and 30 healthy controls.

The present study investigated cognitive impairments in a large sample of patients with anorexia nervosa from an inpatient treatment program. Fifty-nine women with anorexia nervosa were given a battery of neuropsychological tests assessing multiple cognitive domains.
