Abstract:
Models of speech production suggest dissociable phonological difficulties may arise in the semantic versus non-semantic routes to speech output (McCarthy & Warrington, 1984), or at processing levels common to all output tasks (Caplan et al., 1986). An investigation of the phonological disruption in 3 patients with a non-fluent presentation of Dementia of the Alzheimer's Type (DAT) suggests they have difficulty in activating stored phonological representations, especially from semantic specifications.
