This report addresses the efficacy of treatment for functional phonological disorders in children. The definition of phonological disorders and their incidence and prevalence are first presented. The impact of this disorder on the lives of children and the role that speech-language pathologists play in treating this disorder are then discussed. Evidence of(More)
Lexical diffusion, as characterized by interword variation in production, was examined in phonological acquisition. The lexical variables of word frequency and neighbourhood density were hypothesized to facilitate sound change to varying degrees. Twelve children with functional phonological delays, aged 3;0 to 7;4, participated in an alternating treatments(More)
Word frequency and neighborhood density are properties of lexical organization that differentially influence spoken-word recognition. This study examined whether these same properties also affect spoken-word production, particularly as related to children with functional phonological delays. The hypothesis was that differential generalization would be(More)

The Sonority Sequencing Principle is a presumed universal that governs the permissible sequences of consonants within syllables. In two single-subject experiments, we evaluated this principle as applied to the acquisition of onset clusters and adjuncts by children exhibiting functional phonological delays (age in years;months: 3;2 to 7;8). Experiment 1(More)
It has been suggested that a child's productive phonological knowledge may be one factor that potentially accounts for individual differences in generalization learning observed among phonologically disordered children (Dinnsen & Elbert, 1984; Elbert, Dinnsen, & Powell, 1984). This paper evaluates the hypothesis that productive phonological knowledge(More)

The purpose of this paper was to evaluate a phonological treatment program of maximal rather than minimal feature contrasts by charting the course of learning in a child displaying a systematic error pattern involving the nonoccurrence of word-initial consonants. Generalization data indicated that the child learned 16 word-initial consonants following(More)

This study evaluated whether variations in the structure of minimal versus maximal opposition treatments would result in empirical differences in phonological learning. Subjects were 3 children who excluded at least six sounds from their pretreatment phonetic and phonemic inventories. An alternating treatments design in combination with a staggered multiple(More)

This two-part study continued the evaluation of minimal pair treatment in phonological change (Gierut, 1989, 1990, 1991a; Gierut & Neumann, 1992). Three linguistic variables relevant to change were experimentally manipulated within an alternating treatments design to determine specifically the interplay of a maximal number of feature distinctions, feature(More)
The construct of complexity has been advanced recently as a potentially contributing variable in the efficacy of treatment for children with functional phonological disorders. Thus far, complexity has been defined in terms of linguistic and psycholinguistic structure, articulatory phonetic variables, and conventional clinical factors. The focus of this(More)
This study examines the role of homonymy as a motivator of phonological change in treatment. The relative effectiveness of two treatment structures in improving the production of treated and untreated error sounds was evaluated. One treatment structure emphasized homonymous forms by comparing 1:1 a desired ambient target with its corresponding replacement(More)
