This study examined how intervention dose frequency affects phonological acquisition and generalization in preschool children with speech sound disorders (SSD). Using a multiple-baseline, single-participants experimental design, eight English-speaking children with SSD (4;0 to 5;6) were split into two dose frequency conditions (4…

This study explored the feasibility of training school teaching assistants to provide the treatment, Dynamic Temporal and Tactile Cueing to treat childhood apraxia of speech (CAS, also known as developmental verbal dyspraxia). The study used a single case experimental design across behaviours and a qualitative evaluation of teaching assistant…

Intervention with children with speech and language difficulties has been proven beneficial compared with no treatment yet, knowing what type of intervention to provide remains a challenge. Studies of English-speaking children indicate that intervention targeting the production of morphological targets may have a positive effect on phonological…

Language abilities in adolescents with autism spectrum disorders (ASDs) are variable and can be challenging to ascertain with confidence. This study aimed to compare and evaluate different forms of language assessment: standardized language testing, narrative analysis and parent/teacher reports. 14 adolescents with ASD and 14 typically developing…

This study investigated the possibility that similar speech error patterns in children may arise from different patterns of underlying speech processing difficulties. Four Greek children (aged 4;7-5;6 years) with similar speech output difficulties were assessed with a range of experimental tasks with phonologically matched items in order to…

Most children's speech difficulties are "functional" (i.e. no known sensory, motor or intellectual deficits). Speech disorder may, however, be associated with cognitive deficits considered core abilities in executive function: rule abstraction and cognitive flexibility. The study compares the rule abstraction and cognitive flexibility of…

Parents of children with suspected Childhood Apraxia of Speech (sCAS, n = 20), Specific Language Impairment (SLI, n = 20), and typically developing speech and language skills (TD, n = 20) participated in this study, which aimed to quantify and compare reports of early vocal development. Via a questionnaire, parents reported on their child's early…

Children with specific language impairment (SLI) often have extraordinary difficulty in the use of tense and agreement morphemes. Because spontaneous speech samples may not provide a sufficient number of obligatory contexts for these morphemes, structured probe items are often employed. However, these usually emphasize actions that can be readily…

The present study explores the characteristics and concerns of a group of mothers of young people with a history of specific language impairment (SLI). Altogether, 52 young people and their mothers participated. Psychometric tests were used to assess mothers' cognitive and literacy performance and socio-economic status was also recorded. Maternal…
