Early Reading Abilities of Bilingual Children With Nonsyndromic Orofacial Clefts.

OBJECTIVE: To investigate the early reading abilities, and related cognitive-linguistic processes, in bilingual children with nonsyndromic cleft lip and/or palate (CL/P), and to identify deficits that might be amenable to intervention. DESIGN AND PARTICIPANTS: Bilingual participants with CL/P aged 5 to 6 years who were English-dominant ( n=17) or Mandarin-dominant ( n=18) were recruited using consecutive sampling from a national cleft treatment center and matched pairwise to a sample of typically developing (TD) children on language dominance, age, and socioeconomic status. All participants were assessed in English on single-word reading accuracy using the Wide Range Achievement Test (4th Ed), and key cognitive-linguistic factors associated with reading development: phonological awareness, rapid automatized naming (RAN), receptive and expressive vocabulary, and verbal short-term and working memory. RESULTS: CL/P and TD groups were compared within language dominance group (Mandarin or English) for all measures. The Mandarin-dominant CL/P group had significantly poorer reading accuracy and phonological awareness than their TD peers. Additionally, regardless of language dominance, faster RAN correlated significantly with better reading accuracy in both the CL/P groups but not the TD groups. CONCLUSIONS: Children with CL/P who are learning English as a second language are at greater risk of reading difficulties. Furthermore, the cognitive-linguistic processes underlying early reading in bilingual children with CL/P differ from those of their TD peers. Routine screening and tailored intervention is advisable.

Bilingual children with nonsyndromic cleft lip and/or palate: language and memory skills.

PURPOSE: Research shows that monolingual children with cleft lip and/or palate (CLP) have a higher incidence of cognitive-linguistic deficits, but it is not clear whether bilingual preschool children with CLP are especially vulnerable because they need to acquire 2 languages. We tested the hypothesis that bilingual children with CLP score lower than bilingual children with typical development (TD) on receptive vocabulary, verbal memory, and visuospatial memory. METHOD: Participants were 86 bilingual CLP children and 100 TD children 3-6 years of age, dominant in English or Mandarin. Each child completed assessments of English and Mandarin vocabulary, verbal and visuospatial short-term and working memory, hearing, and articulation. RESULTS: With analysis of covariance controlling for age and dominant language, no group differences were found between the CLP and TD bilingual children, although a correlational analysis indicated discrepancies in the relationship between variables. CONCLUSIONS: The findings do not support the hypothesis that preschool children with CLP score lower than preschool children with TD on receptive vocabulary and memory measures. Longitudinal research examining literacy skill development is needed to establish whether the deficits reported for school-age monolingual children with CLP become more obvious in bilingual children in later years, especially when the medium of instruction is the child's nondominant language.
