The aim of the study was to compare approaches highlighting either semantic or phonological features to treat naming deficits in aphasia. Treatment focused on improving picture naming. An alternating treatments design was used with a multiple baseline design across stimuli to examine effects of both approaches in two participants with varying…

Studies investigating voicing onset time (VOT) production by speakers with aphasia have shown that nonfluent aphasics show a deficit in the articulatory programming of speech sounds based on the range of VOT values produced by aphasic individuals. If the VOT value lies between the normal range of VOT for the voiced and voiceless categories, then…

Verb retrieval difficulties are common in aphasia; however, few successful treatments have been documented (e.g. Conroy, P., Sage, K., & Lambon Ralph, M. A. (2006). Towards theory-driven therapies for aphasic verb impairments: A review of current theory and practice. "Aphasiology", 20, 1159-1185). This study investigated the efficacy of a novel…

The objective of this research is to provide an improved automated computational tool to study aphasic production. Using the speech production of Italian aphasic patients, the present study demonstrates the possibility of applying an integrated algorithm to automatically assess and generate error patterns typical of aphasic speech. Philological…

Studies of bilingualism sometimes require healthy subjects to be assessed for proficiency at auditory sentence processing in their second language (L2). The Syntactic Comprehension task of the Bilingual Aphasia Test could satisfy this need. For ease and uniformity of application, we automated its English (Paradis, M., Libben, G., and Hummel, K.…

Literature suggests that illiterate subjects are unaware of the phonological structure of language. This fact may influence the characteristics of aphasic speech, namely the structure of paraphasias. A battery of tests was developed for this study to be used with aphasic subjects (literate and illiterate), in order to explore this topic in more…
