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…

By the age of three, typically developing children can draw conceptual distinctions between "kinds of individual" and "kinds of stuff" on the basis of syntactic structures. They differ from adults only in the extent to which syntactic knowledge can be over-ridden by semantic properties of the referent. However, the relative roles of syntax and…

Non-adjacent dependencies characterize numerous features of English syntax, including certain verb tense structures and subject-verb agreement. This study utilized an artificial language paradigm to examine the contribution of item variability to the learning of these types of dependencies. Adult subjects with and without language-based learning…

The lexical-semantic and syntactic abilities of a group of individuals with chronic nonthalamic subcortical (NS) lesions following stroke (n=6) were investigated using the Western Aphasia Battery (WAB) picture description task [Kertesz, A. (1982). "The Western aphasia battery." New York: Grune and Stratton] and compared with those of a…

This article suggests a possible link between incipient stuttering and early difficulty in language formulation. The hypothesis offers a unifying explanation of an array of empirical observations. Among these observations are the following: early stuttering occurs only on the first word of a syntactic structure; stuttering does not appear to be…
