title: Patterns of sound change in children with phonological disorders.
abstract: This paper presents longitudinal data that provide insight into the phonological learning of five children. These children were superficially similar in that all presented with errors affecting production of [s]; however, it will be argued that each child possessed a phonological system that was unique in certain ways. Production of [s]was established with each participant using a motoric training approach, and generalization was assessed over a 3-4-month period using a 50-item probe. Once treatment was initiated, changes in the production of [s]and in other properties of the phonological systems were observed. Some of these changes illustrated apparent learning strategies that were child-specific, whereas other changes were common to all of these children and may, in fact, be universal in nature.
