Relationship Between the Linguistic Environments and Early Bilingual Language Development of Hearing Children in Deaf-parented Families
2013
We explored variation in the linguistic environments of hearing children of Deaf parents and how it was associated with their early bilingual language development. For that purpose we followed up the children's productive vocabulary (measured with the MCDI; MacArthur Communicative Development Inventory) and syntactic complexity (measured with the MLU10; mean length of the 10 longest utterances the child produced during videorecorded play sessions) in both Finnish Sign Language and spoken Finnish between the ages of 12 and 30 months. Additionally, we developed new methodology for describing the linguistic environments of the children (N = 10). Large variation was uncovered in both the amount…
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…
The development of African American Vernacular English in two fiction texts: a case study
2009
Afroamerikkalainen englanti on Pohjois-Amerikassa ristiriitaisessa asemassa. Kielitieteilijät eivät ole yhteisymmärryksessä kielen syntyperästä ja näin koko kieli ja sen oikeellisuus on kyseenalaistettu Amerikassa. Kielen käyttäjät ovat useimmiten mustia amerikkalaisia, joista useat ovat joutuneet pilkan kohteiksi puhetyylinsä vuoksi. Nykyään monet mustat jopa pitävät kieltään vain slangina tai muuten virheellisenä. Siksi lisää tutkimuksia afroamerikkalaisesta englannista tarvittaisiin. Tässä tutkimuksessa vertailtiin kahta fiktiivistä afroamerikkalaista tekstiä toisiinsa, jotta nähtiin millaisia eroja ja yhtäläisyyksiä kirjailijoiden kielenkäytössä oli. Näistä eroista tehtiin myös johtopä…
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 …
Auditory, speech and language development in young children with cochlear implants compared with children with normal hearing.
2010
Abstract Objective This study had two aims: (1) to document the auditory and lexical development of children who are deaf and received the first cochlear implant (CI) by the age of 16 months and the second CI by the age of 31 months and (2) to compare these children's results with those of children with normal hearing (NH). Methods This longitudinal study included five children with NH and five with sensorineural deafness. All children of the second group were observed for 36 months after the first fitting of the device (cochlear implant). The auditory development of the CI group was documented every 3 months up to the age of two years in hearing age and chronological age and for the NH gro…
Do informal musical activities shape auditory skill development in preschool-age children?
2013
The influence of formal musical training on auditory cognition has been well established. For the majority of children, however, musical experience does not primarily consist of adult-guided training on a musical instrument. Instead, young children mostly engage in everyday musical activities such as singing and musical play. Here, we review recent electrophysiological and behavioral studies carried out in our laboratory and elsewhere which have begun to map how developing auditory skills are shaped by such informal musical activities both at home and in playschool-type settings. Although more research is still needed, the evidence emerging from these studies suggests that, in addition to f…
Social interactional behaviors and symbolic play competence as predictors of language development and their associations with maternal attention-dire…
1999
Abstract Children’s early social interactional behaviors and symbolic play competence were studied at 14 months in a sample of 111 mother-infant pairs. The categories of social interactional behaviors, joint visual attention, socially coordinated and object oriented interactions were assessed via observations of mother-infant joint play. An index of symbolic play was derived from the child’s solitary play, which was assessed independently. We examined both the interrelations of these two types of early language predictors, and their relation to children’s language skills and maternal attention-directing strategies. Measures of children’s language comprehension and production were obtained u…
Modeling the relationship between rapid automatized naming and literacy skills across languages varying in orthographic consistency
2015
The purpose of this study was twofold: (a) to contrast the prominent theoretical explanations of the rapid automatized naming (RAN)-reading relationship across languages varying in orthographic consistency (Chinese, English, and Finnish) and (b) to examine whether the same accounts can explain the RAN-spelling relationship. In total, 304 Grade 4 children (102 Chinese-speaking Taiwanese children, 117 English-speaking Canadian children, and 85 Finnish-speaking children) were assessed on measures of RAN, speed of processing, phonological processing, orthographic processing, reading fluency, and spelling. The results of path analysis indicated that RAN had a strong direct effect on reading flue…
