“…One cognitive domain that has been shown to be abnormal in psychopathy involves attentional and orienting processes (see reviews by Arnett, 1997; Hare, 2003; Kosson & Harpur, 1997; Newman & Lorenz, 2002). In general, psychopaths tend to exhibit relatively small increases in skin conductance in anticipation of a variety of noxious stimuli (e.g., Flor, Birbaumer, Hermann, Ziegler, & Patrick, 2002; Hare, Frazelle, & Cox, 1978; Hare & Quinn, 1971; Lykken, 1957) as well as in response to emotional stimuli, including threatening images (Blair, Jones, Clark, & Smith, 1997), slides of mutilated faces (Mathis, 1970), and emotional sounds, both positive and negative (Verona, Patrick, Curtin, Bradley, & Lang, 2004). The skin conductance response is a component of the orienting reflex (Hare, 1973; Sokolov, 1963), which suggests that psychopathy is associated with abnormal orienting and attentional responses to salient or novel stimuli.…”
