“…On the one hand, 3-4 year-olds distributed more stingily under conditions with high self-interest (mine), matching previous studies in which the resource belonged to the dictator (Benenson, Pascoe, & Radmore, 2007;Blake & Rand, 2010;Fehr et al, 2008). On the other hand, in the absence of personal ownership (not mine), 3-4 year-olds were more egalitarian, a pattern previously suggested to take place among children judging third-party distributions (Blake, McAuliffe, & Warneken, 2014;Smith, Blake, & Harris, 2013), or among 4 year olds in interdependent contexts such as cooperation, joint effort, or impression management (Kanngiesser & Warneken, 2012;Shaw et al, 2014;Tomasello & Vaish, 2013). Here we show that even in the absence of any previous interaction with an actual partner (e.g., cooperation), a mere understanding of ownership statuses provided a range of behavioral outcomes.…”
