Allison, Kristen M.; Cordella, Claire; Iuzzini-Seigel, Jenya; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Despite having distinct etiologies, acquired apraxia of speech (AOS) and childhood apraxia of speech (CAS) share the same central diagnostic challenge (i.e., isolating markers specific to an impairment in speech motor planning/programming). The purpose of this review was to evaluate and compare the state of the evidence on approaches to…

This study examined speech perception abilities among children with CAS with and without language impairment compared to those with…

Iuzzini-Seigel, Jenya; Hogan, Tiffany P.; Green, Jordan R. – Journal of Speech, Language, and Hearing Research, 2017
Purpose: The current research sought to determine (a) if speech inconsistency is a core feature of childhood apraxia of speech (CAS) or if it is driven by comorbid language impairment that affects a large subset of children with CAS and (b) if speech inconsistency is a sensitive and specific diagnostic marker that can differentiate between CAS and…
