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…
Regular rhythmic primes boost P600 in grammatical error processing in dyslexic adults and matched controls
2020
International audience; Regular musical rhythms orient attention over time and facilitate processing. Previous research has shown that regular rhythmic stimulation benefits subsequent syntax processing in children with dyslexia and specific language impairment. The present EEG study examined the influence of a rhythmic musical prime on the P600 late evoked-potential, associated with grammatical error detection for dyslexic adults and matched controls. Participants listened to regular or irregular rhythmic prime sequences followed by grammatically correct and incorrect sentences. They were required to perform grammaticality judgments for each auditorily presented sentence while EEG was recor…
Narraciones escritas en niños con Trastorno Específico del Lenguaje (TEL)
2012
El presente estudio examinó las narraciones escritas, así como la influencia de las variables lingüísticas sobre la competencia narrativa de los niños con Trastorno Específico del Lenguaje (TEL). Veinticinco niños con TEL y 25 niños con desarrollo normal del lenguaje, equilibrados en edad e inteligencia, realizaron una tarea de narración escrita. Los resultados indican que ambos grupos difieren en la producción de narraciones. Los niños con TEL no solo escribieron historias más cortas, sino también de menor organización y coherencia. Además cometieron significativamente más errores de ortografía natural y de sintaxis. Los análisis de regresión jerárquica mostraron que diferentes medidas lin…
Reading Disabilities in children with Specific Language Impairment
2019
El presente estudio examinó el rendimiento en lectura de los niños con Trastorno Específico del Lenguaje (TEL). Treinta niños con TEL y 32 niños con desarrollo normal del lenguaje, equilibrados en género, edad cronológica e inteligencia, fueron evaluados mediante el PROLEC-R. Los resultados de los ANOVAs indicaron que ambos grupos difieren en el rendimiento en lectura. Como grupo, los niños con TEL tuvieron significativamente un rendimiento inferior, tanto en la exactitud como en el tiempo de la lectura de palabras y pseudopalabras, por lo que tenían una menos eficacia de lectura. En la misma línea, el rendimiento de los niños con TEL en comprensión literal e inferencial también fue inferio…
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 …
Sprachentwicklungsstörungen bei Kindern
2009
Wesentliche Voraussetzung für eine ungestörte Kindesentwicklung ist ein regelrechter Spracherwerb. Sprachentwicklungsstörungen (SES) im Kindesalter sind häufig. Für spezifische (isolierte) Sprachentwicklungsstörungen liegt die Prävalenz bei 6 – 8 %; hinzukommen SES, die mit anderen Störungen assoziiert sind. Da flächendeckende Sprachstandserfassungen im Kindergartenalter, die Kinder mit einem SES-Verdacht einer Diagnostik zuführen sollen, auch in Deutschland in den Blickpunkt rücken und eine erhebliche Unsicherheit in der Diagnosestellung von SES und der Verordnungspraxis für Sprachtherapie besteht, sollen die hier in gekürzter Form vorgestellten, überarbeiteten AWMF-Leitlinien der Deutsch…
On natural metalinguistic abilities in aphasia: a preliminary study
2012
Background: Natural metalinguistic abilities, which are put into play without explicit instructions, constitute the cognitive basis for a “reflexive” use of language, a particular manifestation of the executive function when applied to language and verbal behaviour. This reflexive use entails a specific attentional activity by speakers and hearers with regard to linguistic outputs, and an intentional experience-based control over the language use. Putting into play natural metalinguistic abilities can be considered a significant factor for explaining different kinds of adaptive processes. Aims: Preliminary research on natural metalinguistic abilities as manifested in people with aphasia wil…
Infant Event-Related Potentials to Speech are Associated with Prelinguistic Development
2020
Highlights • Speech processing and prelinguistic skills studied in a large longitudinal sample. • Auditory ERPs predicted prelinguistic development in infancy in LCS models. • P1 amplitude at 6 months predicted prelinguistic development between 6 and 12 months. • MMR to a frequency change was associated with prelinguistic skills at 6 months. • Infants’ neural speech processing can help to predict early language development.
