Peer reviewed Peer reviewed

Badcock, Nicholas A.; Bishop, Dorothy V. M.; Hardiman, Mervyn J.; Barry, Johanna G.; Watkins, Kate E. – Brain and Language, 2012
We assessed the relationship between brain structure and function in 10 individuals with specific language impairment (SLI), compared to six unaffected siblings, and 16 unrelated control participants with typical language. Voxel-based morphometry indicated that grey matter in the SLI group, relative to controls, was increased in the left inferior…

Beharelle, Anjali Raja; Dick, Anthony Steven; Josse, Goulven; Solodkin, Ana; Huttenlocher, Peter R.; Levine, Susan C.; Small, Steven L. – Brain, 2010
A predominant theory regarding early stroke and its effect on language development, is that early left hemisphere lesions trigger compensatory processes that allow the right hemisphere to assume dominant language functions, and this is thought to underlie the near normal language development observed after early stroke. To test this theory, we…

Is Expressive Language Disorder an Accurate Diagnostic Category?
Peer reviewed Peer reviewed
Direct linkDirect link
Leonard, Laurence B. – American Journal of Speech-Language Pathology, 2009
Purpose: To propose that the diagnostic category of "expressive language disorder" as distinct from a disorder of both expressive and receptive language might not be accurate. Method: Evidence that casts doubt on a pure form of this disorder is reviewed from several sources, including the literature on genetic findings, theories of language…

Why Impromptu Speech Is Easy To Understand.
Le Feal, K. Dejean – 1982
Impromptu speech is characterized by the simultaneous processes of ideation (the elaboration and structuring of reasoning by the speaker as he improvises) and expression in the speaker. Other elements accompany this characteristic: division of speech flow into short segments, acoustic relief in the form of word stress following a pause, and both…

Beyond Capacity Limitations: Determinants of Word Recall Performance on Verbal Working Memory Span Tasks in Children with SLI
Peer reviewed Peer reviewed
Direct linkDirect link
Mainela-Arnold, Elina; Evans, Julia L. – Journal of Speech, Language, and Hearing Research, 2005
Reduced verbal working memory capacity has been proposed as a possible account of language impairments in specific language impairment (SLI). Studies have shown, however, that differences in strength of linguistic representations in the form of word frequency affect list recall and performance on verbal working memory tasks. This suggests that…

An Assessment Technique for Children with Auditory-Language Processing Problems.
Peer reviewed Peer reviewed
Sanger, Dixie D.; And Others – Journal of Communication Disorders, 1987
A technique for evaluating children's auditory-language processing abilities was developed. Teachers were trained in inservice workshops to identify auditory-language processing problems, using the Observational Profile of Classroom Communication. They subsequently referred 46 nonhandicapped first-, second-, and third-graders for evaluation, which…
