Aberrations in emotional processing of violence-dependent stimuli are the core features of sadism

Psychopathy and sadism are personality traits that share emotional deficits and propensity towards violence. However, sadism should be based on additional affective aberrations: pleasant emotional responses to hurting others or witnessing others in pain. In Study 1 (N = 116) emotional responses to violent and peaceful images and their associations with the subclinical trait sadism are analyzed. The results showed that elevated positive emotions when observing violent stimuli and negative emotions as a reaction to peaceful stimuli predicted sadism, even when variance of psychopathy was controlled in the analysis. In Study 2 (N = 156) implicit associations between violence-dependent stimuli (measured by IAT task) and terms describing positive and negative emotions are analyzed. Again, lower negative associations to violent stimuli predicted sadism, together with psychopathic trait of callous affect. The obtained results provide additional clarification of emotional processes in subclinical sadism.
