The Matching Familiar Figures test of reflection-impulsivity and a test of reading recognition ability (Standard Reading Inventory) were administered to 236 youngsters (ages 8 to 17 years) who were in programs for educable mentally retarded students. Age was, of course, associated with reading recognition, but there was no relationship between Matching Familiar Figures and Standard Reading Inventory scores with age and IQ controlled. This finding casts doubt on the association of reflection-impulsivity as defined by performance on the Matching Familiar Figures test and the ability of retarded children to decode words.
