The current study examined the cultural factors (i.e., religious background, religious participation, parents' views of prayer, and parents' concepts of God) that contribute to children's differentiation between the capabilities of human minds and God's mind. Protestant Christian, Roman Catholic, Muslim, and Religiously Non-Affiliated parents and their preschool-aged children were interviewed (N=272). Children of Muslim parents differentiated the most between God's mind and human minds (i.e., human minds are fallible but God's is not), and children who had greater differentiation between God's and humans' minds had parents who had the least anthropomorphic conceptions of God. Additionally, there was a unique effect of being raised in a Religiously Non-Affiliated home on the degree of children's differentiation between God's and human minds after religious context factors had been accounted for; in other words, children of Religious Non-Affiliates differentiated between humans and God the least and their differentiation was unrelated to religious context factors. These findings delineate the ways in which religious context differences influence concepts of God from the earliest formation.
