Abstract:
:The current study aimed to use electromagnetic articulography (EMA) to investigate the effect of increasing word length on lingual kinematics in acquired apraxia of speech (AOS). Tongue-tip and tongue-back movement was recorded for five speakers with AOS and a concomitant aphasia (mean age = 53.6 years; SD = 12.60) during target consonant production (i.e. /t, s, k/ singletons; /kl, sk/ clusters), for one and two syllable stimuli. The results obtained for each of the participants with AOS were individually compared to those obtained by a control group (n = 12; mean age = 52.08 years; SD = 12.52). Results indicated that the participants with AOS exhibited longer movement durations and, in some instances, larger tongue movements during consonant singletons and consonant cluster constituents embedded within mono- and multisyllabic utterances. Despite this, two participants with AOS exhibited a word length effect that was comparable with the control speakers, and possibly indicative of an intact phonological system.
