Peter, Beate; Button, Le; Stoel-Gammon, Carol; Chapman, Kathy; Raskind, Wendy H. – Clinical Linguistics & Phonetics, 2013
The purpose of this study was to evaluate a global deficit in sequential processing as candidate endophenotypein a family with familial childhood apraxia of speech (CAS). Of 10 adults and 13 children in a three-generational family with speech sound disorder (SSD) consistent with CAS, 3 adults and 6 children had past or present SSD diagnoses. Two…

Button, Le; Peter, Beate; Stoel-Gammon, Carol; Raskind, Wendy H. – Clinical Linguistics & Phonetics, 2013
The purpose of this study was to address the hypothesis that childhood apraxia of speech (CAS) is influenced by an underlying deficit in sequential processing that is also expressed in other modalities. In a sample of 21 adults from five multigenerational families, 11 with histories of various familial speech sound disorders, 3 biologically…

Peter, Beate; Raskind, Wendy H. – Topics in Language Disorders, 2011
Purpose: To evaluate phenotypic expressions of speech sound disorder (SSD) in multigenerational families with evidence of familial forms of SSD. Method: Members of five multigenerational families (N = 36) produced rapid sequences of monosyllables and disyllables and tapped computer keys with repetitive and alternating movements. Results: Measures…
