Recent work has demonstrated the importance of derivational morphology to later language development and has led to a consensus that derivation is a lexical process. In this review, derivational morphology is discussed in terms of lexical representation models from both linguistic and psycholinguistic perspectives. Input characteristics, including…

Children with specific language impairment (SLI) consistently show poor nonword repetition (NWR) performance. However, the reason for these difficulties remains a matter of intensive debate. Nonword repetition is a complex psycholinguistic task that heavily relies upon phonological segmentation and phonological knowledge, and even lexical…

Discusses grammatical morpheme omissions in the phrase productions of children with language impairments. Clinical procedures are described whereby the salience of grammatical morpheme models is increased and the difficulty of production of grammatical morphemes is controlled via manipulation of prosodic contexts to enhance learning of grammatical…

Outlines the stages of prosodic development that children follow from the beginning of word acquisition through the end of the second year of life. How these stages can be used to provide a model for treatment when working with children who display delayed phonological development is addressed. (Author/CR)
