Phonological priming in apraxia of speech and aphasia

This study investigated speech planning in people with aphasia, people with apraxia of speech (AOS), and control speakers using a priming task in which participants name pictures in sets that do or do not share form properties. Two hypotheses were tested: (1) patients with AOS have an impairment in retrieving metrical frames (number of syllables, stress pattern); (2) patients with aphasia have an impairment in retrieving segments. Findings to date (from one patient with AOS and aphasia) suggest interference rather than facilitation. Theoretical and clinical implications will be discussed
