“…One area where in-group preferences also seem to manifest in children"s behaviour is in resource distribution. However, most studies to date have focused on arbitrarily or minimally assigned groups (e.g., Benozio & Diesendruck, 2015) and comparisons of resource giving between known versus unknown recipients, establishing children reliably give more resources (both when the resources are their own or not) to friends, family members and class mates, compared to disliked or unfamiliar peers (Lu & Chang, 2016;Moore, 2009;Paulus & Moore, 2014). Intuitively, this is not surprising, as researchers have suggested behaving in this way can assist in reinforcing social ties and benefit the overall well-being of the group (Rutland & Killen, 2017).…”
