Evidence of basic counting principles has been found in retarded children (Gelman, 1982), including those who are moderately handicapped (Baroody & Snyder, 1983). However, Gelman found no evidence of a stable-order or a cardinality principle in mentally handicapped children with a mental age (MA) of less than 4½ years. The current study examined retarded children in the same MA category to (a) evaluate the hypothesis of a critical MA for learning basic counting principles and (b) further examine how an understanding of counting develops.
