Item English (Scottish) speech development(Oxford University Press, 2024) Scobbie, James M.; Cleland, Joanne; Lawson, Eleanor; Schaeffler, Sonja; McLeod, SharynneScottish English is primarily spoken in Scotland, U.K. It is a national quasi-standard variety of English with a range of social and geographical variants. It can be characterized as a highly distinctive accent (or accent group) of English, mainly due to its relationship to Scots. Its strongly distinct character may be more phonetic, prosodic and lexical than strictly phonemic and phonological, so for practical reasons it can be assumed that its inventory and consonant phonotactics overlap sufficiently with other varieties for many “British English” clinical resources to be applicable. Scottish English is, however, rhotic in its prestige varieties, which makes it markedly different from non-rhotic Southern Standard British English and other non-rhotic varieties. There are few specific studies of children’s acquisition of Scottish English, though Scottish children are often incorporated in larger studies in the U.K. Research on Scottish English has focused on social variation, speech production, and remediation techniques augmented with real time visual biofeedback, involving children with speech sound disorders and cleft palate. Commonly-used speech assessments and interventions have not been developed specifically for this variety of English.Item Development of lingual motor control in children and adolescents(University of Glasgow: Glasgow, 2015-08-10) Zharkova, Natalia; Hardcastle, William J.; Gibbon, Fiona; Lickley, RobinAn important insight into speech motor control development can be gained from analysing coarticulation. Despite a growing number of acoustic and articulatory studies of lingual coarticulation in children, there are conflicting opinions on how the extent of coarticulation changes during childhood. There is also increasing evidence that age-related patterns vary depending on speech sounds involved. The present study employed ultrasound tongue imaging to compare anticipatory V-on-C coarticulation in 13-year-old adolescents and 5-year-old children, using the consonants /p/ and /t/, which differ in the amount of lingual coarticulation in adult speech. For /p/, the two groups had a similar amount of coarticulation. For /t/, both groups had a vowel effect on the extent of tongue bunching, while only adolescents had an effect on the location of tongue bunching. Token-to-token variability in absolute tongue position was larger in the 5-year-olds. We discuss the findings in relation to previous studies and existing theoriesItem Characterizing the Growth Trajectories of Language-Impaired Children Between 7 and 11 Years of Age(2008-06) Law, J.; Tomblin, J. B.; Zhang, X.A number of different systems have been suggested for classifying language impairment in children but, to date, no one system has been widely accepted. Method: This paper outlines an alternative system looking for distinct patterns of change in receptive language skills across time, involving a secondary analysis of children identified as having specific language impairment. Participants: The participants were 184 children age-assessed at 3 time points-7, 8, and 11 years of age. Results: The pattern of receptive language development is highly predictable. The dominant pattern of growth is consistent with declining rates of growth over time for all children. The primary way in which the children differ is with respect to their initial severity. The testing of the 2 classification systems revealed some statistically significant differences among the subtypes with regard to the shape of the growth rates, but the effect sizes associated with these differences were very small. Thus, it is possible to conclude that beyond the dominant pattern of growth, some subtypes of language impairment at 7 years of age showed only subtle differences in receptive language change across time. The results are discussed in terms of the sample selection and the age of the children who were studied. American Speech-Language-Hearing Association.
