Affective features of schizophrenia, which may represent extremes of the dimensions highlighted above, have been related to amygdala function and circuitry (Aleman and Kahn, 2005; Gur et al., 2007). Individuals with schizophrenia are impaired in facial affect perception (Allott et al., 2015; Edwards et al., 2002; Gur et al., 2006; Heimberg et al., 1992; Kohler et al. 2010), especially for threat-related expressions of anger and fear (Edwards et al., 2001; Evangeli and Broks, 2000; Kohler et al., 2003). These deficits are associated with severity of negative symptoms (Gur et al., 2006, 2007). Longitudinal studies indicate persistent impairment, with symptom remission marginally improving performance (Key et al., 2003; Penn et al., 2000). Indeed, deficits on the emotion recognition test had the highest effect sizes (>1.0) for both accuracy and speed in two large samples, the first family-based and the second ascertained in a case-control design (Gur et al., Schiz Res 2015). More recent work demonstrates that these deficits are present as early as the first-episode and are also observed in youths at clinical high risk (CHR) (Addington et al., 2006; van
