Socially, psychopathy expresses extensive callous and manipulative self-serving behaviors with no regard for others, and often is associated with repeated delinquency, crime and violence. Mentally, impairments in processes related to affect and cognition, particularly socially related mental processes, have been found in those with the disorder. 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.[34]
