Item Widening access to electropalatography for children with persistent sound system disorders.(American Speech-Language-Hearing Association, 1999-11) Gibbon, Fiona; Stewart, Fiona; Hardcastle, William J.Previous studies have demonstrated the value of using electropalatography (EPG) to assess, diagnose, and treat persistent sound system disorders in children. However, the application of EPG research has been limited in clinical contexts because most speech-language pathologists do not have access to the technique. This article provides an overview of recent EPG research on persistent sound system disorders and describes a network that has been established to widen access to EPG. The use of EPG via the network is illustrated in the case description of an 8-year-old boy, Robbie, who presented with a persisting speech disorder. The network was used because the clinician treating Robbie did not have an EPG. The main perceptual feature of Robbie's speech before EPG treatment was the deviant phonological process of backing /t/ and /d/ targets to velar place of articulation. EPG was used to assess articulatory patterns before treatment, to provide visual feedback as part of a treatment program, and to record changes in tongue-palate contact patterns as treatment progressed. Robbie achieved normal /t/ and /d/ articulatory patterns after treatment and was subsequently discharged. Factors that could have contributed to the successful outcome in this case are discussed, and areas requiring further research are identified.Item Autosegmental Representation in a Declarative Constraint-based Framework(Garland Publishing Inc., 1997-11-30) Scobbie, James M.Item Whose right? - Who's right?(Royal College of Speech & Language Therapists, 1999) Stansfield, Jois; Hobden, ChristineItem Why do some aphasics show an advantage on some tests of nonpropositional (automatic) speech?(New York, Academic Press, 1999-10-15) Lum, Carmel; Ellis, Andrew W.Sixteen aphasic patients were given three pairs of tasks that compared the production of the same items in either propositional or nonpropositional contexts. A nonpropositional number production task involved counting from 1 to 10 while the propositional version of that task involved naming the Arabic numbers 1 to 10 in nonconsecutive order. A nonpropositional picture-naming task involved naming pictures with the aid of familiar phrase cues (e.g., Don't beat around the BUSH) while in the propositional version the cues were novel phrases (e.g., Don't dig behind the BUSH). Finally a nonpropositional phrase repetition task involved repeating well-known phrases while the propositional version involved repeating novel phrases. The group as a whole showed strong nonpropositional advantages for number production and picture naming with a somewhat weaker advantage for phrase repetition. Only 5 of the individual patients showed nonpropositional advantages on all three pairs of tasks: the remaining 11 patients showed a significant nonpropositional advantage on one or two of the pairs of tasks, but not on all three. All of the patients showed a nonpropositional advantage on at least one pair of tasks, and there were no examples of better performance on the propositional than on the nonpropositional version of any task. Contrasting patterns of performance seen in different patients was related to their performance on a battery of cognitive and linguistic tasks that was given to each patient.Item CLEFTNET SCOTLAND: applications of new technology to the investigation and treatment of speech disorders associated with cleft palate within a Scottish context.(Wiley, 1999) Nairn, M.; Hardcastle, William J.; Gibbon, Fiona; Razzell, R.; Crampin, L.; Harvey, l.; Reynolds, B.Item The application of electropalatography (EPG) to the remediation of speech disorders in school-aged children and young adults(Wiley-Blackwell, 1995-04) Dent, Hilary; Gibbon, Fiona; Hardcastle, William J.Item Electropalatography and its clinical applications.(Singular Publishing Group, 1997, 1997) Hardcastle, William J.; Gibbon, FionaItem Cross-linguistic study of lateral misarticulation using electropalatography(1995-04) Suzuki, N.; Wakumoto, M.; Michi, K.; Dent, Hilary; Gibbon, Fiona; Hardcastle, William J.Item Covert contrasts in children with phonological disorder(1997) Gibbon, Fiona; Scobbie, James M.
