Brief Summary
This project focuses on developing a novel treatment for sentence production and comprehension in aphasia, using implicit priming. First set of experiments will aim examine which learning conditions are most effective in creating maximal training gains. Then, in a later study, the investigators will develop and test the efficacy of a novel treatment study based on findings from the first set of the studies.

Study Arms (1)
Structural priming training
EXPERIMENTALParticipants will be enrolled in 3 sessions of structural priming training (for experiment 1-3) or up to 15 treatment sessions (for experiment 4). Each session will be about 2 hour long, consisting of a set of tasks, including repeating, making, and remembering various types of sentences. In experiment 1-3, each participant will receive two different experimental priming conditions that are being compared within each session. In experiment 4, participants will receive a structural priming treatment in a single-subject design.
Interventions
Participants will be trained to read, make, and recall sentences during each session.

- Access Criteria
- Researchers of OSF will access the study materials or data made available via OSF. Deidentified individual data can also be shared with other researchers upon requests and the PI will review each request. Other supporting materials such as study stimuli or protocols will be shared with other researchers upon request.
We plan to share de-identified individual data with other researchers upon request. Other study materials (e.g., analytic code) will be made available via Open Science Forum. We will also make study-specific data and materials available for journal publications as supplemental materials, as relevant.
