“…Dominant individuals were also found to signal their formidability by lowering their vocal pitch during the initial minutes of a group interaction, whereas those high in prestige do not systematically change their pitch (Cheng, Tracy, Ho, & Henrich, 2013). Individuals high in dominance versus prestige also demonstrate divergent hormonal (i.e., Testosterone) profiles (Johnson, Burk, & Kirkpatrick, 2007); patterns of economic decision making (Bruno, 2006;Halevy, Chou, Cohen, & Livingston, 2012); differential perceived attractiveness and desirability (Snyder, Kirkpatrick, & Barrett, 2008); and, in small-scale societies, reproductive success and nutritional health status (Reyes-Garcia et al, 2009;von Rueden, Gurven, & Kaplan, 2011). Collectively, these studies provide converging support for the claim that dominance and prestige are distinct and independent processes that simultaneously give rise to and underpin human rank relationships.…”
