Giovannone, Nikole; Theodore, Rachel M. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The extant literature suggests that individual differences in speech perception can be linked to broad receptive language phenotype. For example, a recent study found that individuals with a smaller receptive vocabulary showed diminished lexically guided perceptual learning compared to individuals with a larger receptive vocabulary. Here,…

Hamilton, Lorna G.; Hayiou-Thomas, Marianna E.; Hulme, Charles; Snowling, Margaret J. – Scientific Studies of Reading, 2016
The home literacy environment (HLE) predicts language and reading development in typically developing children; relatively little is known about its association with literacy development in children at family-risk of dyslexia. We assessed the HLE at age 4 years, precursor literacy skills at age 5, and literacy outcomes at age 6, in a sample of…

Lewis, Barbara A.; Short, Elizabeth J.; Iyengar, Sudha K.; Taylor, H. Gerry; Freebairn, Lisa; Tag, Jessica; Avrich, Allison A.; Stein, Catherine M. – Topics in Language Disorders, 2012
Purpose: The purpose of this study was to examine the association of speech-sound disorders (SSD) with symptoms of attention-deficit/hyperactivity disorder (ADHD) by the severity of the SSD and the mode of transmission of SSD within the pedigrees of children with SSD. Participants and Methods: The participants were 412 children who were enrolled…

Kegel, Cornelia A. T.; Bus, Adriana G. – Journal of Child Psychology and Psychiatry, 2013
Background: The dopamine D4 receptor gene (DRD4) has been linked to attention deficit hyperactivity disorder (ADHD) and reading disorders. In this study, we examined whether diminished anticipatory dopamine cell firing--typical of the long variant of the DRD4 allele--is related to emergent and advanced alphabetic skills, and whether executive…

De Diego-Balaguer, R.; Couette, M.; Dolbeau, G.; Durr, A.; Youssov, K.; Bachoud-Levi, A.-C. – Brain, 2008
Although the role of the striatum in language processing is still largely unclear, a number of recent proposals have outlined its specific contribution. Different studies report evidence converging to a picture where the striatum may be involved in those aspects of rule-application requiring non-automatized behaviour. This is the main…

Whitehouse, Andrew J. O.; Barry, Johanna G.; Bishop, Dorothy V. M. – Journal of Communication Disorders, 2008
Some children with autism demonstrate poor nonword repetition--a deficit considered to be a psycholinguistic marker of specific language impairment (SLI). The present study examined whether there is an SLI subtype among children with autism. We compared the language abilities of children with SLI (n = 34, M age = 11;10 S.D. = 2;3), and children…
