Note. AOS = apraxia of speech; R = right; AE = American English; SE = Spanish–English bilingual; BE = British English; TPO = time post onset; LH = left hemisphere; CVA = cerebrovascular accident; RH = right hemisphere; B = Broca's area; I = insula; PreC = precentral gyrus; n/a = not available; PF= posterior frontal lobe; FT = fronto-temporal; PT = posterior & middle temporal lobe; IO = inferior occipital lobe; T = temporal lobe; O = occipital lobe; IFG = inferior frontal gyrus; P = parietal lobe; WNL = within normal limits; WAB-R = Western Aphasia Battery–Revised; AQ = aphasia quotient; mod = moderate.
Pure-tone hearing screening at 500, 1000, 2000, and 4000 Hz; pass at 40 dB level for better ear.
Based on the WAB-R (Kertesz, 2006), except for APH 304 (based on Boston Diagnostic Aphasia Examination–Third Edition; Goodglass et al., 2000).
Based on Apraxia Battery for Adults–Second Edition (Dabul, 2000).
Mean rating across three diagnosticians (1 = no AOS, 2 = possible AOS, 3 = AOS).
Dysarthrias were diagnosed perceptually based on a motor speech exam (Duffy, 2005) and were all of the unilateral upper motor neuron type.
