Cognitive and communicative development in deaf and hearing-impaired children with cochlear implants and/or hearing-aids
- 2011

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of the study was to examine neurophysiological, cognitive and linguistic development in deaf and hearing-impaired children (5–7 years of age) with CI and/or hearingaids and how a phonological intervention programme may influence this development. The deaf and hearing-impaired children were compared with age-matched hearing children. The results reveal that deaf and hearing-impaired children had equivalent or close to equivalent performance levels compared to hearing children for cognitive and linguistic tasks with relatively low demands on phonological processing, whereas there was a substantial and significant difference between the groups for cognitive tasks involving explicit phonological processing. The results indicate that there is a relationship between age at implant and neurophysiological, cognitive and linguistic development, where early implantation promotes faster development. The childrens´ cognitive performance increased as a function of phonological intervention.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Thirty-two children with hearing impairment (HI) using cochlear implants (CI) and/or hearing aids (HA), and sixteen with normal hearing (NH) participated in a computer-assisted intervention study that focused on perceiving and memorizing phonemic sounds. The first purpose was to study cognitive abilities in NH and HI children, how they related to phonological processing skills (PhPS) pre intervention and to phonological growth post intervention. The second purpose was to analyze children’s performance at different fine-grained levels of phonological processing, i.e. how they manipulated, stored and produced phonological entities of different size with or without semantic content. This was put in relation to children’s type of auditory stimulation (electrical; bilateral CI, bimodal: CI + HA and acoustical; bilateral HA). Results showed significant correlations between complex working memory and PhPS in children with HI but not in children with NH. This suggests different cognitive strategies in the children when dealing with phonological processing tasks. Poor phoneme discrimination was the strongest predictor of phonological growth in the children with HI as a function of training. Thus, the computer-assisted program was beneficial for HI children with weak initial phoneme discrimination skills. Children with CI showed reduced performance at fine-grained levels of receptive phonological processing but not on expressive phonological lexical tasks.

Computer-assisted intervention for Deaf and Hard of hearing (D/HH) children with cochlear implants or hearing aids : Cognitive factors and phonological change
- 2013
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Aim: Study cognitive abilities; specifically working memory and lexical access in NH and DHH children, and their correlations to phonological processing skills (PhPS) pre intervention. Analyze how cognitive abilities related to phonological change post intervention. Material and Method: Tasks for lexical access, complex and visual working memory and Phpr were assessed pre and post intervention.Conclusion: DHH children performed at a lower level than NH children on lexical access but equally on complex and visual working memory. Significant correlations between complex working memory and PhPS were evident in DHH children but not in NH. This suggests that DHH children recruit more cognitive resources when performing PhPr tasks. Weak initial performance on a task for phonological representations (Phrep) was the only significant predictor of phonological change in DHH children. Weak PhRep was associated with a higher age at diagnosis, higher age at implant, and shorter usage-time with CI.

Tidskriftsartikel (refereegranskat)abstract
- The present study examined computer-assisted reading intervention with a phonics approach for deaf and hard of hearing (DHH) children in Sweden using cochlear implants or hearing aids, or a combination of both. The study included 48 children, 5, 6 and 7years of age. Sixteen children with normal hearing (NH) served as a reference group. The first purpose of the study was to compare NH and DHH children's reading ability at pre and post-intervention. The second purpose was to investigate effects of the intervention. Cognitive and demographic factors were analyzed in relation to reading improvement. Results showed no statistically significant difference for reading ability at the group level, although NH children showed overall higher reading scores at both test points. Age comparisons revealed a statistically significant higher reading ability in the NH 7-year-olds compared to the DHH 7-year-olds. The intervention proved successful for word decoding accuracy, passage comprehension and as a reduction of nonword decoding errors in both NH and DHH children. Reading improvement was associated with complex working memory and phonological processing skills in NH children. Correspondent associations were observed with visual working memory and letter knowledge in the DHH children. Age was the only demographic factor that was significantly correlated with reading improvement. The results suggest that DHH children's beginning reading may be influenced by visual strategies that might explain the reading delay in the older children.
