predict antisocial behavior in adolescent male twins, which was due to genetic liability shared between endophenotype and outcome (Niv et al., 2015); alpha asymmetry has been found to predict depression (Mitchell & Possel, 2012); reduced delta and theta event-related power (Yoon et al., 2015) and P300 amplitude (Carlson, Iacono, & McGue, 2004; W. G. Iacono et al., 2002; Yoon et al., 2015) are reported to predict externalizing disorders; reduced high-frequency power has been found to predict autism; increased ERN is reported to predict the onset of anxiety disorders (Meyer, Hajcak, Torpey-Newman, Kujawa, & Klein, 2015); reduced feedback positivity is reported to predict subsequent depression (Proudfit, 2015); reduced MMN amplitude has been found to predict the development of psychosis in at-risk individuals (Shaikh et al., 2015); and reduced resting heart rate in childhood has been found to predict antisocial behavior in adulthood (Raine, Venables, & Williams, 1990). This latter finding was recently corroborated and extended in a longitudinal study of more than 700,000 men in Sweden, which found that lower resting heart rate in late adolescence among military conscripts was associated with significantly elevated hazard of being convicted of violent and nonviolent crimes as well as assault and unintentional injuries in
