Résumé

WIn this paper, we investigate stress clash resolution, i.e., how speakers readjust the metrical patterns of an utterance to preserve its metrical regularity. We test the effect of working memory (WM) capacities in control (C) subjects and individuals with Multiple Sclerosis (MS) on their ability to look-ahead to the metrical structure of an utterance and compute changes in prominence structure in the clash condition. We predict that if WM capacities affect stress clash resolution, MS patients with low WM capacities will not be able to look ahead and will fail to apply stress resolution. Our results do not provide evidence of stress clash resolution for both C and MS subjects, suggesting neither stress shift nor stress deletion took place. Yet, some evidence is provided that MS speakers with low WM capacities narrow down the scope of the prosodic planning unit, thus suggesting that variation in planning strategies depend on cognitive skills. We discuss our results along different models of French prosody.
