Effects of Verb Overlap on Structural Priming in Dialogue: Implications for Syntactic Learning in Aphasia
Peer reviewed Peer reviewed
Direct linkDirect link
Man, Grace; Meehan, Sarah; Martin, Nadine; Branigan, Holly; Lee, Jiyeon – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Although there is increasing interest in using structural priming as a means to ameliorate grammatical encoding deficits in persons with aphasia (PWAs), little is known about the precise mechanisms of structural priming that are associated with robust and enduring effects in PWAs. Two dialogue-like comprehension-to-production priming…

Coran, Monica; Rodriguez-Fornells, Antoni; Ramos-Escobar, Neus; Laine, Matti; Martin, Nadine – Topics in Language Disorders, 2020
Objective: Of current interest in aphasia research is the relevance of what we can learn from studying word learning ability in aphasia. In a preliminary study, we addressed 2 issues related to the novel word learning ability of individuals with aphasia. First, as word learning engages large-scale cognitive-linguistic systems (language skills,…

Model Choice and Sample Size in Item Response Theory Analysis of Aphasia Tests
Peer reviewed Peer reviewed

Hula, William D.; Fergadiotis, Gerasimos; Martin, Nadine – American Journal of Speech-Language Pathology, 2012
Purpose: The purpose of this study was to identify the most appropriate item response theory (IRT) measurement model for aphasia tests requiring 2-choice responses and to determine whether small samples are adequate for estimating such models. Method: Pyramids and Palm Trees (Howard & Patterson, 1992) test data that had been collected from…

Raymer, Anastasia M.; Beeson, Pelagie; Holland, Audrey; Kendall, Diane; Maher, Lynn M.; Martin, Nadine; Murray, Laura; Rose, Miranda; Thompson, Cynthia K.; Turkstra, Lyn; Altmann, Lori; Boyle, Mary; Conway, Tim; Hula, William; Kearns, Kevin; Rapp, Brenda; Simmons-Mackie, Nina; Gonzalez Rothi, Leslie J. – Journal of Speech, Language, and Hearing Research, 2008
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…

A Case-Series Test of the Interactive Two-Step Model of Lexical Access: Predicting Word Repetition from Picture Naming
Peer reviewed Peer reviewed
Direct linkDirect link
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…

A Case-Series Test of the Interactive Two-Step Model of Lexical Access: Evidence from Picture Naming
Peer reviewed Peer reviewed

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…
