Northwest Aphasia Registry and Repository
The NW Registry and Repository (R&R) serves as a participant pool for studies conducted in the Aphasia Research Lab, as well as a way to keep the Aphasia Research Lab in touch with the aphasia community. Individuals with aphasia who are interested in being involved in research first sign up for the R&R. Following testing, their eligibility for various research studies in the lab is evaluated, and individuals may be contacted later to be offered the opportunity to participate. Registry:
Masked Priming Treatment for Anomia
Most treatments for anomia involve highly explicit approaches, with clinicians providing feedback and clients analyzing their responses to work on making them more accurate. Typical language use, on the other hand, is supported largely by implicit, unconscious processes. This project is exploring a new approach to treating word retrieval impairments in aphasia designed to bypass much of the explicit processing that typically occurs in treatment, targeting and strengthening implicit processes important to supporting language function.
Aphasic comprehension: conflict resolution and short-term memory
People with aphasia (PWA) are variable in their language abilities from one occasion to the next. This individual variability may be accounted for by other cognitive mechanisms, short-term memory (STM) and conflict resolution (CR) among them. STM is defined as the process underlying the maintenance of activated linguistic information over a short period or delay. CR is defined as an executive attention process underlying the inhibition of interfering stimuli or response selections.
Timing of Implicit Processes in Aphasia
The rapid and accurate use of language is supported by cognitive networks that operate implicity; that is, they are outside of conscious awareness or control. Prior behavioral evidence suggests that the timing of these networks' operations is altered in aphasia. Specifically, evidence suggests that activation within these networks spreads more slowly for people with aphasia than for typical adults, and that it is maintained for a shorter than typical period of time.
Modification and Validation of a Measure of Chronic Stress for People with Aphasia
While many people benefit from aphasia treatments, others do not. This unexplained variability in aphasia treatment outcomes is likely due to a number of factors. Chronic stress – reportedly experienced by many people with aphasia – is a potentially modifiable factor that may impact degree of treatment success. Recent neuropsychological research findings suggest chronic stress may be a substantial barrier to the neuroplasticity required for rehabilitation.
A prospective, controlled study of rehabilitation of anomia in aphasia
The traditional treatment approach to the rehabilitation of anomia in aphasia is to explicitly train individuals with aphasia in whole word naming (see Nickels, 2002, for extensive review) (often called lexica/semantic therapy). Controlled studies have shown that this approach may improve naming performance but generalization is typically very limited; that is, the knowledge gained by the patient tends to be limited to the words actually trained, and there is at best modest improvement in naming performance with untrained words.
