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…

Analysis of spontaneous language samples of eight children (4-11 years old) diagnosed with developmental verbal apraxia (motor speech disorder) revealed that at least some of the errors could not be attributed to motor speech and/or phonologic limitations but rather indicated concomitant syntactic disorders.

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…

The FG syndrome is characterized by unusual facies; sudden infant death; developmental delay; and abnormalities of the cardiac, gastrointestinal, and central nervous systems. Serial evaluations of one case with isolated agenesis of the corpus callosum found consistent patterns over time in specific language impairments in syntactic and…

Sixteen adults with language/learning disabilities (L/LD) and 16 controls participated in a study testing sensitivity to word order cues that signaled grammatical versus ungrammatical word strings belonging to an artificial grammar. Participants with L/LD performed significantly below the comparison group, suggesting that this skill is problematic…

The receptive and expressive "wh" interrogative performance of 20 language-delayed children (4.3 to 6.4 years old) was compared to available normative data. These findings suggest that the delayed children develop the same order of acquisition and rules for questioning as normal children, but at a slower rate. (Author/SEW)

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…

Twenty-seven American Indian children (ages 4-12), 10 with Fetal Alcohol Syndrome (FAS) and 17 normally developing control subjects, were administered the Test of Language Development. FAS children exhibited depressed performance on most subtests. The older FAS children presented syntactic deficits whereas the younger FAS subjects presented more…
