Background: Psycholinguistic models of language production provide a framework for determining the locus of language breakdown that leads to speech-sound disorder (SSD) in children. Aims: To examine whether children with SSD differ from their age-matched peers with typical speech and language development (TD) in the ability phonologically to…

Purpose: When speakers retrieve words, they do so extremely quickly and accurately--both speed and accuracy of word retrieval are compromised in persons with aphasia (PWA). This study examined the contribution of two domain-general mechanisms: processing speed and cognitive control on word retrieval in PWA. Method: Three groups of participants,…

Children with primary or "specific" language impairment (PLI) demonstrate subtle deficits in non-linguistic cognitive processing skills that may play a causal or contributing role in PLI. The purpose of this study was to investigate the possibility that short-term treatment of non-linguistic cognitive processing skills improves language abilities…

Studies into the effects of ageing on language in adults with Down syndrome (DS) have tended to rely on measures that lack sensitivity to change because they fail to explore across linguistic domains or rely on proxy reports. The study aim was to use measures of receptive and expressive language from studies of younger individuals with DS in…

This study of rapid picture naming by 20 normally developing children (mean age 11 years) found significant differences between two-and three-dimensional pictures for higher level vocabulary items, but not for lower-level vocabulary items, suggesting that dimensionality may be a critical feature for rapid lexical access for higher-level picture…

A study investigated some of the ways in which phenomena are perceived and translated into speech, especially in the assignment of agents in a given situation. Subjects were 16 adults with infant children. The adults were shown the Visual Cliff series of pictures of an infant crawling to its mother across a glass sheet covering an open space with…

Previous research on typically developing children has shown that their memory for events depends on how they are encoded. As children grow older, they start to mention causal and temporal relationships between events, including psychological causes. Children with specific language impairment (SLI) were studied to disentangle the effects of…
