Effects of working memory demands on sentence production in aphasia

The purpose of the study was to investigate the effects of task demands on sentence production and their relation to working memory (WM) capacity in people with aphasia using a verb-final language. The current study manipulated the WM loads on the sentence production tasks by varying the following three factors: task type (syntactic priming vs. sentence completion), sentence type (active vs. passive), and canonicity (canonical vs. noncanonical word order). Task type and word order canonicity were related to individual differences in WM capacity in both people with aphasia and their normal controls.
