A “fine-cuts” approach disentangling psychopathic, autistic and alexithymic traits in their associations with affective, cognitive and motor empathy

Atypical empathy is seen in relation to psychopathy and autistic traits; however, studies typically conflate affective and cognitive facets of empathy. Moreover, motor empathy has been suggested as another facet of empathy, advocating for further delineation of empathy dimensions. In addition, alexithymia may affect responding to emotional, cognitive or motor states in others. The current study investigated how psychopathic, autistic and alexithymic traits are associated with those empathy facets. Nonclinical participants ( N = 212) completed online self-report measures of affective, cognitive and motor empathy, primary and secondary psychopathy, autistic and alexithymic traits. A subsample ( N = 157) also completed a behavioral measure of motor empathy (i.e., behavioral synchrony) using a virtual agent. Whilst all traits were associated with reduced cognitive empathy and behavioral synchrony; path analyses supported a mediation model of cognitive empathy difficulties through alexithymia only for primary psychopathy. Secondary psychopathy and alexithymia were associated with increased motor empathy, specifically tendencies to mimic negative emotions. In contrast, primary psychopathy was associated with reduced affective empathy and inhibition of positive emotion imitation, despite reporting self-other overlap experiences induced by behavioral synchrony. Overall, these findings highlight the need for a “fine-cuts” approach; delineating the role of empathy subfacets in atypical empathy.
