“…This could be attributed to a range of methodological issues but also raises the possibility of important within-culture variations in naïve psychology. Some studies have provided evidence that within culture, the rates of development will vary according to number of siblings (e.g., Perner et al, 1994;Jenkins and Astington, 1996); birth order (e.g., Ruffman et al, 1998;Howe et al, 2005); availability of extended family members (e.g., Lewis et al, 1996); socioeconomic status (e.g., Holmes et al, 1996;Cutting and Dunn, 1999;Garner et al, 2005), parenting style (e.g., Ruffman et al, 1999Ruffman et al, , 2006Vinden, 2001); language development (e.g., Astington, 2001;Astington and Baird, 2005); within-family communication about mental states (e.g., Dunn and Dale, 1984;Dunn et al, 1987Dunn et al, , 1991Youngblade and Dunn, 1995;Ruffman et al, 2002); genetic influences (e.g., Hughes and Cutting, 1999); and family relationships (e.g., Hughes et al, 2005). These subtle differences are also likely to be evident between cultures and while gross cultural differences are important more subtle cultural variations, particularly where cultures are distinct but similar, should not be ignored.…”
