Metacognitive Deficiency in a Perceptual but Not a Memory Task in Methadone Maintenance Patients

Abstract Drug addiction has been associated with lack of insight into one’s own abilities. However, the scope of metacognition impairment among drug users in general and opiate dependent individuals in particular is not fully understood. Investigating the impairments of metacognitive ability in Subs...
