“…In the course of developing the Pizzagame, we aimed to find a scenario that was as close to a life-like situation as possible. In line with other peer-based paradigms (Crowley, Wu, Molfese, & Mayes, 2010;Gunther Moor, Bos, Crone, & van der Molen, 2014;Guyer, Choate, Pine, & Nelson, 2012;Reijntjes, Stegge, Terwogt, Kamphuis, & Telch, 2006), we presumed that a situation in which boys and girls ostensibly interacted with same-age, same-sex peers in a school setting would act as a familiar and ecologically valid cue to trigger children's everyday social behavior. The importance of these aspects is persuasively underscored by ample data showing that concrete, familiar, and relevant scenarios improve performance on a variety of cognitive tasks, even among adults (e.g., Sperber & Girotto, 2002;Wason & Shapiro, 1971), and facilitate earlier understanding among children (e.g., Doherty, 2009;Donaldson, 1978).…”
