Abstract
Recent work suggests that brief restriction to articulation may result in hyperarticulation in children’s productions after this restriction is removed. We set out to examine whether temporarily restricting tongue movement during a listening phase would lead to a greater category separation for difficult-to-articulate sounds (/s/ and //) post-restriction. We also examined whether typically developing children (TD) and children with speech sound disorder (SSD) were equally impacted by restriction. To do this we audio recorded the production of non-words with /s/ and // in a post-restricted and a non-restricted condition and then measured the center of gravity at the beginning of each target sound. While no evidence of hyperarticulation was found, results revealed that TD children showed no difference in their productions during the restricted and non-restricted conditions, however, children with SSD globally reduced center of gravity in the restricted condition. These findings suggest that children with SSD may have had difficulty in restoring normal tongue tip range immediately post perturbation. Thus, children with SSD may exhibit slower motor recovery compared with TD peers.
