“…The relationships between resting HR and aggression (e.g., Lorber, 2004;Ortiz & Raine, 2004), and sensation seeking and aggression (e.g., Wilson & Scarpa, 2011) have been well established. For example, a recent meta-analysis found that sensation seeking and aggression are significantly positively related, albeit with a small effect size (d ¼ .19, Wilson & Scarpa, 2011). Furthermore, a few previous studies have found that baseline HR and sensation seeking are significantly inversely related (e.g., De Pascalis, Valerio, Santoro, & Cacace, 2007).…”
