Timing processing and rhythm reproduction deficits in patients with aphasia

Timing processing and rhythm reproduction deficits in patients with aphasia

The purpose of the present study is to assess timing and rhythm reproduction ability in patients with aphasia, and further investigate a possible relationship among timing, rhythm and working memory. Twelve patients with aphasia and twenty-one healthy participants were recruited for this study. The Finger Tapping Test was used for timing and rhythm reproduction. “Timing tapping task” consisted of two phases, a synchronization and a continuation phase, with 3 fixed intervals (250ms, 500ms, 1000ms). “Rhythm tapping task” involved 21 rhythmic patterns with 3-8 blips per rhythm and intervals of 250ms or/and 1000ms between the blips. Working memory in two modalities, through Digit Span and through Corsi Block-Tapping Task, was evaluated as well. The results showed deficient performance of aphasic patients in timing and in rhythm reproduction compared to controls. In timing task, aphasic patients exhibited poorer accuracy and greater variability when tapping the long (1000ms) and short (250ms) intervals, in the synchronization and continuation phase, respectively. In the rhythm task, 65.5% of patients reproduced at least one pattern incorrectly, independently of the rhythm complexity. Moreover, patients exhibited severe deficits in verbal working memory. Based on the results, a significant relationship among the deficits in timing, rhythm and working memory tasks was not found in the patient group compared to healthy controls, in which timing and rhythm performance and also rhythm reproduction and verbal working memory performance were strongly correlated. It is concluded that patients with aphasia have impairments in timing, rhythm and working memory tasks; however, the relationship between these impairments requires further investigation.
