Purpose: The intent of this study was to examine the longitudinal morpho-syntactic progression of children with Speech Sound Disorders (SSD) grouped according to Mean Length of Utterance (MLU) scores. Methods: Thirty-seven children separated into four clusters were assessed in their pre-kindergarten and Grade 1 years. Cluster 1 were children with…

Ten language-impaired children, aged 4-6, were found to exhibit more pronounced syntactic deficits than 10 normal children matched by mean length of utterance. Language samples were analyzed with respect to: grammatical marker need index; grammatical marker error index; and grammatical marker errors for nouns, verbs, bound, and unbound forms.…

The language transcripts of seven children with Down syndrome (DS) and seven typically developing children with comparable mean length of utterance levels were compared for verb argument structure. Findings suggest that syntactic difficulties may delay children with DS in overcoming the optional subject phenomena and the lesser number of anomalous…
