Left hemisphere enhancement of auditory activation in language impaired children

2019

| openaire: EC/H2020/641652/EU//ChildBrain Specific language impairment (SLI) is a developmental disorder linked to deficient auditory processing. In this magnetoencephalography (MEG) study we investigated a specific prolonged auditory response (N250m) that has been reported predominantly in children and is associated with level of language skills. We recorded auditory responses evoked by sine-wave tones presented alternately to the right and left ear of 9–10-year-old children with SLI (n = 10) and children with typical language development (n = 10). Source analysis was used to isolate the N250m response in the left and right hemisphere. In children with language impairment left-hemisphere …

Chromosome 15q BP3 to BP5 deletion is a likely locus for speech delay and language impairment: Report on a four‐member family and an unrelated boy

2020

Abstract Background Deletions in chromosome 15q13 have been reported both in healthy people and individuals with a wide range of behavioral and neuropsychiatric disturbances. Six main breakpoint (BP) subregions (BP1‐BP6) are mapped to the 15q13 region and three further embedded BP regions (BP3‐BP5). The deletion at BP4‐BP5 is the rearrangement most frequently observed compared to other known deletions in BP3‐BP5 and BP3‐BP4 regions. Deletions of each of these three regions have previously been implicated in a variable range of clinical phenotypes, including minor dysmorphism, developmental delay/intellectual disability, epilepsy, autism spectrum disorders, behavioral disturbances, and speec…

Infant information processing and family history of specific language impairment: converging evidence for RAP deficits from two paradigms

2007

An infant's ability to process auditory signals presented in rapid succession (i.e. rapid auditory processing abilities [RAP]) has been shown to predict differences in language outcomes in toddlers and preschool children. Early deficits in RAP abilities may serve as a behavioral marker for language-based learning disabilities. The purpose of this study is to determine if performance on infant information processing measures designed to tap RAP and global processing skills differ as a function of family history of specific language impairment (SLI) and/or the particular demand characteristics of the paradigm used. Seventeen 6- to 9-month-old infants from families with a history of specific l…

Information structure in language acquisition. Production and comprehension of (in)definite articles by German-speaking children.

2020

AbstractThe present study investigates the production and comprehension of indefinite and definite articles as markers of givenness by typically-developing German-speaking children, from the perspective of information structure theory. The study involves 93 typically-developing children aged four to seven years old with normal language-skills and 20 adults. The results of a story-narration task and a truth-value judgment task reveal that children have more problems with new than with given referents in production as well as comprehension suggesting a “given better than new”-pattern. These findings are explained in the context of perspective-taking capacities and cue weighting theory.

Early language and behavioral regulation skills as predictors of social outcomes.

2012

Purpose In the present study, the authors examined the prospective associations among early language skills, behavioral regulation skills, and 2 aspects of school-age social functioning (adaptability and social skills). Method The study sample consisted of children with and without a familial risk for dyslexia. The authors analyzed the relations among children’s language (at age 2;6 [years;months] and age 5;0), behavioral regulation skills (at age 5;0), and social functioning (at age 8;0) using structural equation modeling. Subgroups of children with respect to language and behavioral regulation skills (at age 5;0) were identified through the use of mixture modeling. Results Among at-risk …

Intragenic KANSL1 mutations and chromosome 17q21.31 deletions: broadening the clinical spectrum and genotype-phenotype correlations in a large cohort…

2015

Background The 17q21.31 deletion syndrome phenotype can be caused by either chromosome deletions or point mutations in the KANSL1 gene. To date, about 60 subjects with chromosome deletion and 4 subjects with point mutation in KANSL1 have been reported. Prevalence of chromosome deletions compared with point mutations, genotype–phenotype correlations and phenotypic variability have yet to be fully clarified. Methods We report genotype–phenotype correlations in 27 novel subjects with 17q21.31 deletion and in 5 subjects with KANSL1 point mutation , 3 of whom were not previously reported. Results The prevalence of chromosome deletion and KANSL1 mutation was 83% and 17%, respectively. All patient…

Audiovisual speech perception in children with developmental language disorder in degraded listening conditions.

2013

Purpose The effect of the signal-to-noise ratio (SNR) on the perception of audiovisual speech in children with and without developmental language disorder (DLD) was investigated by varying the noise level and the sound intensity of acoustic speech. The main hypotheses were that the McGurk effect (in which incongruent visual speech alters the auditory speech percept) would be weaker for children with DLD than for controls and that it would get stronger with decreasing SNR in both groups. Method The participants were 8-year-old children with DLD and a sample of children with normal language development. In the McGurk stimuli, the consonant uttered by the voice differed from that articulated …

[The importance of socio-cultural factors for the development of speech and language].

Factors determining the efficiency of logopaedic care of children in Poland.

2000

The purpose of this article is to establish factors which determine the efficiency of the system of care provided to children with speech disorders attending regular schools and kindergartens. The analysis was made using Poland as an example, which, similar to other countries, has made some achievements in this matter. Although Poland has had an institutionalised care system for children with speech development anomalies for 30 years, the problem of speech disorders is still very difficult to solve. Due to the large scale of the phenomenon among Polish children, this problem can be defined as a social problem in this country. The above-described situation makes it necessary to search for me…

In search of a science-based application: A learning tool for reading acquisition

2009

This is a story about the fate of a psychological application: from its conception to the optimistic vision surrounding its future. We hope that this application - an enjoyable learning game (www or mobile phone-based, available free of charge to the end users) for children - can at best help millions of children in their reading acquisition in the future. Its basis was created by following intensively the development of children with (N = 107) and without (N = 92) genetic (familial) risk for dyslexia from birth to puberty in the Jyväskylä Longitudinal study of Dyslexia (JLD)-project. We summarize some of the major findings of the JLD in order to facilitate understanding of the reasons and …
