Atthough Piaget eventually acknowle

Atthough Piaget eventually acknowledged that different cultural groups might foster different ways of thinking, he gave virtually no attention to culture as a prominent factor affecting cognitive development *Chapman, 1988). Yet research indicates that the course of cognitive development varies somewhat from one cultural group to another, probably because different cultures give children somewhat different experiences (Maynard & Greenfield, 2003; Morra et al.,2008). For example, Mexican children whose families make pottery for a living acquire conservation skills earlier than their peers in other Mexican families (Price Williams, Gordon, & Ramirez, 1969).Apparently, making pottery requires children to make frequent judgments about needed quantities of clay and water-Judgments that must be fairly accurate regardless of the specific shape or form of the clay or water container. In other cultures, especially in some where children don’t attend school, conservation appears several years later than it does in Western cultures, and formal operational reasoning may never appear at all (M. Cole, 1990;Fahrmeier,1978).In such contexts, some logical reasoning skills may simply have little relevance to people’s daily lives (J.G. Miller, 1997; Morra et al.,2008).
