METHODS Twenty-one patients with severe mental retardation were subject to chromosomal analysis. The lymp...

The body awareness of 124 toddlers with mental retardation and of 124 children developing normally matched to them on age and gender was examined. Twenty-nine of the children with mental retardation were diagnosed as Down syndrome (DS). The 'Pointing and Naming' Test of Bergès and Lézine [Bergès, J., & Lézine, I. (1978).
