“…Preschoolers’ performance on elicited-response false-belief tasks is correlated with a variety of social factors (e.g., Perner et al, 1994; Holmes et al, 1996; Dunn and Cutting, 1999; Hughes et al, 1999; Meins et al, 2003; Lecce and Hughes, 2010; Mayer and Träuble, 2013; McAlister and Peterson, 2013; for detailed discussions of these factors and children’s social experience, see Carpendale and Lewis, 2004; Wellman, 2014; Taumoepeau, 2015). For instance, preschoolers from larger families (e.g., Perner et al, 1994) and those with same-aged or older siblings (e.g., McAlister and Peterson, 2013) show superior performance on elicited-response false-belief tasks.…”
