Abstract
The purpose of this investigation was to explore the interaction between delays in the acquisition of phonology, semantics, and syntax. Three goals were established. The first was to explore the relation between expressive syntax and phonological deviancy. The second was to explore the relation between receptive syntax and phonology. The third was to determine if the size of the receptive vocabulary was related to phonological deficiency.
A total of 39 normal-hearing children, who ranged from 48 to 60 months of age, served as subjects. Of the 39, 7 were girls and 32 boys. The expressive and receptive communication skills were assessed. Only those subjects in need of therapeutic intervention for speech and language deficiencies were included in the study.
Several data analysis procedures were used, the most important one being a principal-axis factor analysis. This method was used to identify the lines of agreement among phonological performance, receptive vocabulary, and grammatical morpheme comprehension. Results of the principal-axis factor analysis (PAFA) led to the extraction and interpretation of three factors that characterized co-occurring phonological and semantic/syntactic delays in children. The factors were interpreted as the Verbal Comprehension factor, the Word Production factor, and the Word Meaning factor. Phonological performance was represented by the Word Production factor. Receptive vocabulary was represented by the Word Meaning factor. Grammatical morpheme comprehension was represented by the Verbal Comprehension factor. It was discovered that Word Meaning and Verbal Comprehension were highly intercorrelated and that both were not perpendicular nor parallel to Word Production.
The initial observation by the author was that there was a strong association between co-occurring phonological and semantic/syntactic delays. The results obtained did not support the anticipated association, although, these aspects of communication were shown to be correlated to some degree.
