Domain general pattern sequencing is thought to be a primary area of deficit in children with specific language impairment (SLI), as predicted by Ullman and Pierpont’s (2005) procedural deficit hypothesis. We delineate manual and articulatory evidence that is required for empirical support of the procedural deficit hypothesis and present preliminary articulatory movement data from young children with SLI and their typically developing peers. Children produced sentences that decreased in computational load and increased in automaticity over an extended period of learning. Consistent with the procedural deficit hypothesis, children with SLI showed deficits in articulatory sequencing when they generated a sentence in a priming task. As they transitioned to an imitation task and practiced the utterance, group differences diminished. These findings suggest that the motor deficit in SLI is not one of implementation, but rather related to higher order organization and sequencing. This research was supported by NIH/NIDCD R01DC04826. |
