Previous research by Bates and her colleagues (1979) has demonstrated that a specific profile of correlations or a local homology is characteristic of the development of sensorimotor and early communication skills in 9- to 13-month-old normal children. The purpose of this study was to examine the developmental generality of this earlier finding by examining the association of sensorimotor and early communication skills in developmentally delayed children. Three groups of delayed children with MA ranges of 2 to 7 months, 8 to 13 months, or 14 to 21 months were assessed on independent measures of sensorimotor and early communication abilities. The profile of correlations among sensorimotor and early communication measures in the 8- to 13-month MA group was very similar to the data that were previously obtained for normal children. Measures of means-end and object play were correlated with a number of early communication abilities; however, other sensorimotor abilities entered into relatively few correlations with early communication abilities. These data support the developmental generality of the local homology and show that the profile of correlations among sensorimotor and early communication abilities differed across MA groups.
