This article compares the claims of rule- and constraint-based accounts of three seemingly distinct error patterns, namely, Deaffrication, Consonant Harmony and Assibilation, in the sound system of a child with a phonological delay. It is argued that these error patterns are not separate problems, but rather are symptoms of a larger conspiracy to…

Miccio's work included a number of articles on the assessment of phonology in children with phonological disorders, typically using measures of correct articulation, using the PCC, or analyses of errors, using the framework of phonological processes. This paper introduces an approach to assessing phonology by examining the phonetic complexity of…

Toddlers in the lowest 10th percentile for lexical production were compared with age- and language-matched controls on measures of phonetic complexity, lexical development, and grammatical complexity. Results indicate an overlap between phonology, lexicon, and grammar and suggest the importance of true consonant production for lexical development.…
