Psychopathy is a personality disorder which has symptoms expressed over a wide range of settings. Socially, it expresses extensive callous and manipulative self-serving behaviors with no regard for others, and often is associated with repeated delinquency, crime and violence, but may also present itself in other, maybe even successful social settings. Mentally, impairments in processes related to affect (emotion) and cognition, particularly socially related mental processes, have been found in those with the disorder which suggest that their destructive social behavior is borne from these aberrant mental processes. Developmentally, symptoms of psychopathy have been identified in young children with conduct disorder, and is suggestive of at least a partial constitutional factor that influences its development.
