Brief Report: Immediate Memory for Movement Sequencesin Children With and Without Language Impairment
Canadian Journal of Speech-LanguagePathology and Audiology
This study investigated the immediate recall and reproduction of visually presented movements by children with and without language impairments (LI). Ten children with LI ranging in age from 6:0 to 8:9 (years:months) and 10 age-matched peers with typically-developing language completed tasks requiring them to reproduce sequences of nonsymbolic arm movements that were presented at eight different rates of speed ranging from .5 s per movement to 4 s per movement. The children with LI performed significantly poorer than the control group in recalling arm movements across the presentation rates. Both groups of children tended to recall and reproduce arm movements presented at very slow intervals (4 s per movement) better than they recalled and reproduced arm movements presented at very fast intervals (.5 s per movement). These results suggest that children with LI have immediate visuospatial memory deficits for serial position and that children both with and without LI benefit from having visual information presented at a slow rate.
