About this trial

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.
