The purpose of this study was to investigate which of 26 prepositions are acquired expressively by educable mentally retarded children. This study was designed to 'determine if there was a significant difference between the number of prepositions expressed by an EMR sample and those expressed by normals of similar mental age, and if the same prepositions were used by the two groups at given mental ages. The correlation between chronological age and the number of prepositions expressed by the EMR population was also investigated.
