Progressive apraxia of Speech (PAoS) is a progressive motor speech disorder associated with neurodegenerative disease causing impairment of phonetic encoding and motor speech planning. Clinical observation and acoustic studies show that duration analysis provides reliable cues for diagnosis of the disease progression and severity of articulatory disruption. The goal of this paper is to develop ...

Immediate memory span and maximal articulation rate were assessed for word sets differing in frequency, word-neighborhood size, and average word-neighborhood frequency. Memory span was greater for high- than low-frequency words, greater for words from large than small phonological neighborhoods, and greater for words from high- than low-frequency phonological neighborhoods. Maximal articulation...

The evidence of supporting phonological deficit as a cause of developmental dyslexia has been accumulating rapidly over the past 2 decades, yet the exact mechanisms underlying this deficit remain controversial. Some authors assume that a temporal processing deficit is the source of the phonological disorder observed in dyslexic children. Others maintain that the phonological deficit in dyslexia...

The precise structure of speech sound representations is still a matter of debate. In the present neurobiological study, we compared predictions about differential sensitivity to speech contrasts between models that assume full specification of all phonological information in the mental lexicon with those assuming sparse representations (only contrastive or otherwise not predictable information...

BACKGROUND expressive vocabulary of children with normal and deviant phonological development. AIM to determine whether alterations presented by children with phonological disorders occur only at the phonological level or if there are any impacts on lexical acquisition; to compare the vocabulary performance of children with phonological disorders to reference values presented by the used test...

PURPOSE The purpose of this study was to examine the relationship between the types of speech errors that are produced by children with speech-sound disorders and the children's phonological awareness skills during their prekindergarten and kindergarten years. METHOD Fifty-eight children with speech-sound disorders were assessed during the spring of their prekindergarten year and then again a...

This talk is devoted to a rather ‘conceptual’ discussion of some notions that bear directly on the relationship between phonology and morphosyntax. First I will discuss some of the original formulations of the principle of Dual Articulation (Dual Patterning) as found in the work of Martinet, Meillet and Hockett, and then we’ll see how dual articulation is now often understood. Initially, there ...

PURPOSE The purpose of this study was to examine the longitudinal predictive relationships among variables that may contribute to poor phonological awareness skills in preschool-age children with speech-sound disorders. METHOD Forty-seven children with speech-sound disorders were assessed during the spring of their prekindergarten year and again at the end of their kindergarten year. Hierarch...

The current study addresses the extent of phonological planning during spontaneous sentence production. Previous work shows that at articulation, phonological encoding occurs for entire phrases, but encoding beyond the initial phrase may be due to the syntactic relevance of the verb in planning the utterance. I conducted three experiments to investigate whether phonological planning crosses mul...

Objectives: The purpose of this study was to examine the phonological processing skills between children with delay and disorder compared those typically developing children. This aimed explore whether show general or specific weakness on if can differentiate from disorder. Methods: participants were 27 speech sound disorders (SSDs) 20 Children SSDs consisted 10 17 tasks for involved awareness ...
