Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue Sep 2023

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …


The Impact Of Semantics And Syntax On Lexical Retrieval In Individuals With Aphasia, Marta M. Korytkowska Jun 2023

The Impact Of Semantics And Syntax On Lexical Retrieval In Individuals With Aphasia, Marta M. Korytkowska

Dissertations, Theses, and Capstone Projects

Nearly all people with aphasia (PWA) report difficulty with lexical retrieval (i.e., anomia). While there are several tasks used to measure lexical retrieval, each poses different degrees and types of challenges. For example, some studies have found that PWA performance varies depending on the type of lexical retrieval task. The tasks that have been used include lexical retrieval in isolation tasks (such as picture-naming), lexical retrieval in sentence level tasks (such as narration tasks), and lexical retrieval in sentence-completion tasks. Some studies have found no differences between the accuracy of lexical retrieval in isolation and at the sentence level (e.g., …
