ABSTRACT

PURPOSE: Shared parenting among caregivers of different gender is common in the Swedish society. It is unclear if this includes shared contribution for children's language development. The objective of this cross-sectional study was to explore the natural language environment of children who were hard-of-hearing compared to typically hearing controls. METHODS: Seventy-two families with children aged 7-35 months participated; 22 children who were hard-of-hearing (Cochlear implants, n=11; Hearing aids, n=11) and 50 controls with typical hearing. The majority of caregivers had higher education background level, especially in the control group. Families conducted a daylong recording with the Language Environment Analysis technology, when both parents were present at home. An Interpreted Time Segmental analysis was performed to extract information about female versus male caregivers quantitative word use. RESULTS: The results showed significant gender differences related to number of adult words, with less male words than female words (p <0.001). Male caregivers of children who were hard-of-hearing contributed with around 27 % of adult words during the recordings while males in the control group contributed with 37 %. There was a larger variation in number of female words in the study group than for controls, especially in mothers of children with cochlear implants. CONCLUSIONS: Female caregivers talk significantly more close to young children than male caregivers, and especially in the subgroup of children with cochlear implants. Children who are hard-of-hearing are dependent on a rich language environment, and might be especially vulnerable if male caregivers are less involved as language facilitators. More studies are needed to explore caregiver gender differences, both related to quantitative and qualitative language stimulation.

ABSTRACT

AIM: Evidence suggests that cochlear implants are beneficial for language development, but there is no consensus about the ideal age for surgery. We investigated how language development and surgical safety were affected by patients' ages. METHODS: This study comprised 103 children (52 boys) aged 4.3-16 years who received cochlear implants at 5-29 months at the Karolinska University Hospital, Stockholm, Sweden, between 2002 and 2013. All showed typical development and were from monolingual homes. Bilateral implants were common (95%). The children were regularly assessed on language understanding, vocabulary and speech recognition by a multi-disciplinary team for 10.0 ± 3.7 (4.7-16.0) years. RESULTS: There were no associations between complications after surgery and the age when children had their first implant. Children implanted at 5-11 months reached an age-equivalent level of language understanding and better vocabulary outcome sooner than subgroups implanted later. Children who had surgery at 12-29 months demonstrated more atypical and delayed language abilities over time. Early implantation, preferably before 9 months, may lead to a more typical trajectory of spoken language development. CONCLUSION: Our findings showed that cochlear implantation before 9 months was safe. Early implantation may reduce the negative effects of auditory deprivation and promotes more natural and synchronised language development.

ABSTRACT

Children with a profound hearing loss who have been implanted with cochlear implants (CI), vary in terms of their language and reading skills. Some of these children have strong language skills and are proficient readers whereas others struggle with language and both the decoding and comprehension aspects of reading. Reading comprehension is dependent on a number of skills where decoding, spoken language comprehension and receptive vocabulary have been found to be the strongest predictors of performance. Children with CI have generally been found to perform more poorly than typically hearing peers on most predictors of reading comprehension including word decoding, vocabulary and spoken language comprehension, as well as working memory. The purpose of the current study was to investigate the relationships between reading comprehension and a number of predictor variables in a sample of twenty-nine 11-12-year-old children with profound hearing loss, fitted with CI. We were particularly interested in the extent to which reading comprehension in children with CI at this age is dependent on decoding and receptive vocabulary. The predictor variables that we set out to study were word decoding, receptive vocabulary, phonological skills, and working memory. A second purpose was to explore the relationships between reading comprehension and demographic factors, i.e., parental education, speech perception and age of implantation. The results from these 29 children indicate that receptive vocabulary is the most influential predictor of reading comprehension in this group of children although phonological decoding is, of course, fundamental.

ABSTRACT

This study set out to explore the cognitive and linguistic correlates of orthographic learning in a group of 32 deaf and hard of hearing children with cochlear implants, to better understand the factors that affect the development of fluent reading in these children. To date, the research about the mechanisms of reading fluency and orthographic learning in this population is scarce. The children were between 6:0 and 10:11 years of age and used oral language as their primary mode of communication. They were assessed on orthographic learning, reading fluency and a range of cognitive and linguistic skills including working memory measures, word retrieval and paired associate learning. The results were analyzed in a set of correlation analyses. In line with previous findings from children with typical hearing, orthographic learning was strongly correlated with phonological decoding, receptive vocabulary, phonological skills, verbal-verbal paired-associate learning and word retrieval. The results of this study suggest that orthographic learning in children with CI is strongly dependent on similar cognitive and linguistic skills as in typically hearing peers. Efforts should thus be made to support phonological decoding skill, vocabulary, and phonological skills in this population.
