Home Literacy Environment and Emergent Skills in Preschool Children With Hearing Loss

The use of a computer-based program focused on the syllabic method to support early literacy in children with cochlear implants

BACKGROUND

Children with cochlear implants (CIs) often lag behind children with normal hearing (NH) in early literacy skills. Furthermore, the development of language skills associated with their emergent literacy skills seems to depend on good auditory access. Supporting language acquisition and early literacy in children with CIs may prevent difficulties in primary school. The use of technology may facilitate auditory and speech recovery in children with CIs, but evidence on computer-based early literacy programs is limited.

OBJECTIVE

This study investigates (a) the effects of a computer-based program focusing on the syllabic method on the literacy skills of children with CIs (CIs group), comparing them with the literacy skills of a group of age-matched NH (normal hearing) peers (NHs group); (b) the associations between language and early literacy skills in the NHs group and between language, auditory and early literacy skills in the CIs group.

METHOD

Nine prelingually deaf children with CIs (M = 61.11, SD = 6.90) with severe to profound sensorineural hearing loss and nine age-matched NH children participated in the program. Categories of Auditory Performance (CAP) as measures of children's auditory skills were collected. All participants were tested on phonological, morphosyntax (grammatical comprehension and repetition), and early literacy skills (syllable blending and segmentation, syllable and word reading) (T1). Next, all children participated in the computer-based program for 12 weeks. After the program was completed (T2), only early literacy tests were administered to the children.

RESULTS

Although, on average, both groups obtained higher scores in all literacy tasks at T2, the CIs group scored lower than the NHs group. In the CIs group, at T2 we found significant improvements in syllable segmentation (p = 0.042) and word reading (p = 0.035). In the NHs group, at T2 we found significant improvements in syllable segmentation (p = 0.034), syllable blending (p = 0.022), syllable reading (p = 0.008), and word reading (p = 0.009). We also found significant associations in both groups between measures of morphosyntax at T1 and measures of early literacy at T2. In addition, for the CIs group, we found significant associations between children's auditory performance at T1 and measures of morphosyntax at T1 and early literacy at T2.

CONCLUSION

a computer-based program focused on the syllabic method could support children with CIs in acquiring emergent literacy abilities. The auditory performance of children with CIs seems to influence their morphosyntax and later early literacy skills.

Home Literacy Experiences and Shared Reading Practices: Preschoolers With Hearing Loss

Home literacy experiences and observed parent and child behaviors during shared book reading were investigated in preschool-age children with hearing loss and with typical hearing to examine the relationships between those factors and children's language skills. The methods involved parent-reported home literacy experiences and videotaped parent-child dyads during shared book reading. Children's language skills were tested using the Preschool Language Scale-4. The results indicated significant differences between groups for home literacy experiences and observed parent and child behaviors. Parents of children with hearing loss were found to read more frequently to their children than parents of children with typical hearing, yet scored lower for literacy strategies and teaching techniques compared to parents of children with typical hearing. Children with hearing loss scored lower in interactive reading behaviors compared to children with typical hearing. For children with hearing loss, frequency of book reading and child interactive reading behaviors were strong predictive factors for children's language skills. These results suggest that families of children with hearing loss would benefit from professional support as they read storybooks to their children. Similarly, children with hearing loss should be encouraged to be more interactive during shared book reading.

Testing the validity of a self-report scale, author recognition test, and book counting as measures of lifetime exposure to print fiction

We report a study testing the validity of the three most commonly used indicators of lifetime exposure to print fiction, namely a self-report scale, an author recognition test (ART), and book counting, in a sample of older adults (N=306; Mage = 59.29 years, SDage = 7.01). Convergent validity of the self-report scale and book counting was assessed through correlations with the fiction sub-score of the ART; divergent validity of these two indicators was examined via correlations with the non-fiction sub-score of that ART. We also assessed criterion-related validity by testing the degree to which each of the three indicators predicted participants' performance in a vocabulary test. The self-report scale and book counting were significantly more positively associated with the ART fiction sub-score than the ART non-fiction sub-score. Regression analyses, controlling for gender and non-fiction exposure, revealed that the ART fiction sub-score had the highest explanatory power among all indicators under investigation for predicting vocabulary test performance. The present results suggest that only ARTs may have satisfactory levels of both construct and criterion-related validity. Recommendations for the assessment of fiction exposure and future directions are discussed.

Impact of home literacy environment on literacy development of children with hearing loss: A mediation model

Reading presents an unsolved difficulty for children with hearing loss and research on factors influencing their literacy development is very limited. This work aimed to study the influence of home literacy environment (HLE) on literacy development of children with hearing loss and explore possible mediating effects of reading interest and parent-child relationship. 112 Chinese children with hearing loss were surveyed for scales of HLE, literacy development, reading interest, and parent-child relationship. Result analysis showed that HLE significantly predicted literacy development of children with hearing loss and this effect was no longer significant after including reading interest and parent-child relationship as variables. Further, HLE significantly predicted reading interest and parent-child relationship, each of which predicted literacy development and played a significant mediating role in HLE’s influence on literacy development. These findings provide educational tips for families of children with hearing loss.

Auditory Experience, Speech Sound Production Growth, and Early Literacy in Children Who Are Hard of Hearing

PURPOSE

Children who are hard of hearing (CHH) are at risk for literacy difficulties. Speech sound production is related to literacy skills in typically hearing children. Speech sound production abilities can also be markedly weak in CHH due to inconsistent access to the speech signal. We longitudinally examined relations between auditory experience, speech sound production abilities, and literacy (i.e., nonword reading and spelling in second grade) in CHH.

METHOD

Participants included 166 CHH. All participants used hearing aids (HAs). Auditory experience is a weighted measure of the number of hours of daily HA use and the amount of audibility with and without their HAs. Children's speech sound production was tested 2-3 times between the ages of 3 and 9 years. At age 5 years and again in second grade, children were tested on a battery of language and literacy measures.

RESULTS

Auditory experience was significantly correlated with speech sound production abilities, but age at HA fitting was not. Speech sound production abilities at age 5 years did not predict nonword reading in second grade but did predict spelling skills in second grade.

CONCLUSIONS

Our results support the importance of auditory experience and speech sound production for later literacy abilities. Specifically, we found that speech sound production abilities and print knowledge at age 5 years are related to second grade spelling outcomes. Interestingly, we found that morphological knowledge at age 5 years was more predictive of decoding in second grade than was speech sound production. Although there are multiple factors that contribute to literacy success, our results underscore the unique contributions of speech sound production abilities in CHH.
