Purpose: Language production in semantic dementia (SD) is characterized by a lexical-semantic deficit and largely preserved argument structure and inflection production. This study investigates (a) the effect of argument structure on verb retrieval and (b) the interrelation between inflection marking and verb retrieval in SD. Method: Seven…

Purpose: With Aim 1, we compared the comprehension of and sensitivity to canonical and noncanonical word order structures in school-age children with specific language impairment (SLI) and same-age typically developing (TD) children. Aim 2 centered on the developmental improvement of sentence comprehension in the groups. With Aim 3, we compared…

This study investigated the use of cognitive state verbs (CSVs) and complement clauses in children with specific language impairment (SLI) and their typically developing (TD) peers. In Study 1, conversational samples from 23 children with SLI (M = 6;2), 24 age-matched TD children (M = 6;2) and 21 vocabulary-matched TD children (M = 4;9) were…

Semantically reversible sentences are prone to misinterpretation and take longer for typically developing children and adults to comprehend; they are also particularly problematic for those with language difficulties such as aphasia or Specific Language Impairment. In our study, we used fMRI to compare the processing of semantically reversible and…

This paper describes various aspects of syntactic theory, including lexical, functional, and phrasal categories and how they are put together in clauses and sentences, how words are represented in the mental lexicon, and how noun phrases are assigned structural and semantic information. Language acquisition and the treatment of language disorders…

Background: Receptive language impairments in school-age children have a poor prognosis, yet there is a dearth of research on effective interventions. Aims: Children's responses to a computerized grammatical training program were evaluated to consider whether repeated responding to spoken sentences with variable semantic content and the same…

Presents the case for a mapping theory of developmental language impairment, which branches into a theory that specific language impairment arises from impaired phonological processing and the consequent disruption of the mapping process through which the words and sentence structure of language are established.
