Purpose: In this article, the authors encapsulate discussions of the Language Work Group that took place as part of the Workshop in Plasticity/NeuroRehabilitation Research at the University of Florida in April 2005. Method: In this narrative review, they define neuroplasticity and review studies that demonstrate neural changes associated with…

Dell, Gary S.; Martin, Nadine; Schwartz, Myrna F. – Journal of Memory and Language, 2007
Lexical access in language production, and particularly pathologies of lexical access, are often investigated by examining errors in picture naming and word repetition. In this article, we test a computational approach to lexical access, the two-step interactive model, by examining whether the model can quantitatively predict the repetition-error…

Schwartz, Myrna F.; Dell, Gary S.; Martin, Nadine; Gahl, Susanne; Sobel, Paula – Journal of Memory and Language, 2006
Many facts about aphasic and nonaphasic naming are explained by models that use spreading activation to map from the semantics of a word to its phonology. The implemented model of picture naming discussed here achieves this by coupling interactive feedback with two selection steps. The model's structure and default parameters were set up to match…
