Memory and Language: Insights from Aphasia

When: Monday, April 11, 15:00 – 15:50

Where: Deree Faculty Lounge

Organized by: Faculty Research Seminars 2015-16 Series

 


Aphasia is traditionally considered to be an acquired language impairment, due to a focal (usually left-lateralized) brain lesion. However, during the last decades, there has been mounting evidence that aphasic patients also demonstrate non-linguistic processing deficits. This presentation is focused on the relationship between language and memory deficits. Three studies of an ongoing research project carried out by the Neuropsychology Unit of Eginition Hospital will be presented. The first study (Potagas et al., 2011) investigates the relationship between working memory and aphasic deficits, and further suggests a possible underlying common mechanism. The second study (Kasselimis et al., 2013a) aims to clarify whether such memory deficits are dependent on the presence of aphasia in left brain damaged patients. The third study (Kasselimis et al., 2013b) investigates possible effects of lesion extent and location on modality-independent and modality-specific memory deficits in aphasia. The findings of the above papers are discussed in the context of the relevant aphasiology literature.
