Previous research with aphasic patients has shown that picture naming can be facilitated by concurrent phonemic cueing [e.g. initial phoneme(s) of the word that the patient is trying to retrieve], both as an immediate word retrieval technique, and when practiced repeatedly over time as a long-term anomia treatment. Here, to investigate the neural mechanisms supporting word retrieval, we adopted...

After a moderate head injury a 33-year-old woman presented a selective defect in finding verbs and name actions. Objects, colors, body parts, and qualities were named in a normal way. No other associated aphasic defects were observed. It was proposed that the selection and use of verbs in their correct forms implies two different aspects, which eventually can become dissociated: (1) the ability...

The processes required for object naming were addressed in a study of patients with semantic dementia (a selective decline of semantic memory resulting from progressive temporal lobe atrophy) and in a computational model of single-word production. Although all patients with semantic dementia are impaired in both single-word production and comprehension, previous reports had indicated two differ...

PURPOSE Previous research has demonstrated that exposure to masked primes may improve naming accuracy for individuals with anomia. This study investigates the effect of repeated exposures to masked identity primes paired with pictures over multiple trials, sessions, and days on the ability of people with anomia to name those pictures. METHOD Four participants with anomia completed this single...

Electrophysiological correlates of recovery from anomia were analysed in four aphasic patients in the post-acute stage. Event-related potentials (ERPs) were recorded during picture naming at baseline and after a period of therapy for anomia. All patients had severe anomia at baseline assessment and improved significantly in naming during the study period. Waveform analyses and temporal segmenta...
