Comments regarding Dodd and Iacano (1989): 'Phonological disorders in children: Changes in phonological process use during treatment'

Abstract

Dodd and Iacano [sic] (1989) report the effects of phonological treatment with seven phonologically disordered children, ages 3;0-4;9 years. The subjects' pre-treatment speech samples were analysed for application of 'developmental' and 'unusual' (deviant) phonological processes, and treatment targeted at unusual processes was administered to each child. The results, as interpreted from the measurement of four dependent variables to be discussed below, showed improved speech-sound production, reduced use of both developmental and unusual phonological processes, and individualised patterns of phonological change.
