“…Low resting HR has been meta-analytically shown to be related to various antisocial disorders and behaviors including conduct disorder/oppositional defiant disorder (CD/ODD), offending, aggression, and psychopathy ( Lorber, 2004 ; Ortiz and Raine, 2004 ; Portnoy and Farrington, 2015 ). However, effect sizes of the relationship have been shrinking with time ( Portnoy and Farrington, 2015 ) and some recent, large-scale studies have failed to find significant associations ( Oldenhof et al, 2018 ; Prätzlich et al, 2018 ). The relationship between other resting measures of the ANS and antisocial behavior has not been investigated as intensively as HR, but studies suggest that increased resting PEP is related to conduct problems and aggression ( Beauchaine et al, 2013 ); reduced resting SCL is related to psychopathy and conduct problems ( Lorber, 2004 ); and reduced resting RSA is related to externalizing problems and antisocial behavior ( Beauchaine et al, 2007 ; de Wied et al, 2009 ; Graziano and Derefinko, 2013 ).…”
