Fearlessness is a core clinical feature of Psychopathy. Many assume that this fear deficit results from impairment in the limbic system. We have convincingly demonstrated that reduced fear in Psychopathy is secondary to deficits in early selective attention. Specifically, psychopaths display deficient fear only when their attention is engaged early by goal-relevant stimuli that prevent subsequent attention and elaboration of threats. Conversely, when threats are goal-relevant or otherwise in the focus of attention, psychopaths exhibit robust, normative fear. More recently, Baskin-Sommers, Curtin, & Newman (2015) have provided preliminary evidence on how cognitive retraining tasks predicated on these deficits can serve to ameliorate this fear deficit and associated behavioral dysregulation.
