Utveckling av kognitiva färdigheter och läsförmåga hos barn med mild och måttlig hörselnedsättning i ett ettårsperspektiv

Sammanfattning: The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research. The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year. Eleven Swedish children aged 7:6-10:10 years participated in this study. To illustrate progress of the abilities mentioned the SIPS computer test battery and furthermore some manually given tests for reading and prosodic abilities were used. The results show a developmental trend for the children with hearing impairment on tests of working memory and reading comprehension. The least degree of development was found in the area of phonological skills. The children with hearing impairment showed in general the same capacity as normal hearing children on tests for the different abilities. In the area of working memory the children with hearing impairment had significant lower results on half of the tests than age adequate normal hearing children. Several strong connections were present for children with hearing impairment this year than last year, in-between cognitive skills and reading ability. Correlation appeared between age for insertion of hearing aid and test for decoding ability. Results on tests for prosodic ability reached ceiling effect.
