“…However, the response modulation deficits associated with psychopathy and externalizing appear to involve distinct psychobiological processes (Baskin-Sommers & Newman, 2013; Newman, 1997; Patterson & Newman, 1993). Whereas the dysregulated behavior of psychopathic individuals is associated with early attention problems (i.e., attention bottleneck) and reduced emotional reactivity (Baskin-Sommers, Curtin, Li, & Newman, 2011; Baskin-Sommers et al, 2011; Wolf et al, 2011), the dysregulated behavior of externalizing individuals entails exaggerated emotional reactivity and subsequent deficiencies in selective attention (i.e., Baskin-Sommers, Curtin, Larson, Stout, Kiehl, & Newman, 2012; Baskin-Sommers, Wolf, et al, 2012). Thus, individuals displaying a combination of psychopathic and externalizing traits will not necessarily display a more extreme response modulation deficit.…”
