Reading Comprehension and Working Memory Capacity in Children with Hearing Loss and Cochlear Implants or Hearing Aids

Research output: Contribution to journalArticle


Reading comprehension and three aspects of working memory—general,
visuospatial and phonological—was assessed in 41 children with hearing
loss: 23 with cochlear implants and 18 with hearing aids. Performance on
these tests was compared between the two groups of children with hearing
loss and also related to that of 55 children with typical hearing. All children
were between 6 and 14 years of age.
The children with hearing aids performed significantly more poorly
on the reading comprehension test than the children with typical hearing
but this difference was not significant between the children with cochlear
implants and the children with typical hearing. In the group of children with
cochlear implants, the results from the reading test and the results from all
three working memory tests correlated significantly, whereas in the group
of children with hearing aids there was no correlation between the reading
test and the visual working memory test. The reading test results from the
children with typical hearing correlated significantly with the results from the
phonological working memory test but not with the other working memory
tests. The authors concluded that the children with cochlear implants might
have developed orthographic decoding earlier than the children with hearing
aids due to their more profound hearing loss.
