الملخص EN

This research aims to investigate the differences in verbal working memory and Speech- Understanding between unilateral cochlear implants children and bilateral cochlear implants children and normal hearings children.

The research’s sample consisted of three groups.

The first group consisted of 60 children with unilateral cochlear implants (40 boys, 20 girls) the second group consisted of 30 children with bilateral cochlear implants (20 boys, 10 girls), and the third group consisted of 60 children with normal hearing, (30 boys, 30 girls) their age ranging from (6- 9) years old.

The parity has been mad between these three groups in number of demographic factors, such as age, intelligence quotients (IQ), and the family’s social and economic level.

And the auditory age of children with cochlear implants was determined 3years at least.

The study employed a measure of verbal working memory test (one of the subtest of Stanford binet scales of intelligence the structure of the fifth image) and speech- understanding scale (the researcher prepared) were applied, and the results of the study revealed the presence of statistically significant differences between children with unilateral cochlear implant and children with bilateral cochlear implant and normal hearing children in verbal working memory.

There are also statistically significant differences between children with unilateral cochlear implants, and normal hearing children, in speech understanding.

And by using the analysis of variance between the three groups as a statistical method to arrive at the nature of the differences between them and the direction of the differences between the groups.

It was found that there are statistically significant differences between children with unilateral cochlear implants and children with bilateral cochlear implants in the verbal working memory towards children with bilateral cochlear implants as well as the presence of statistically significant differences between children with unilateral cochlear implants and normal hearing children in verbal working memory towards normal hearing children and the presence of statistically significant differences between children with bilateral cochlear implants and normal hearing children towards normal hearing children.

While there are no statistically significant differences between the group of children with cochlear implants and normal children in the components of understanding questions, understanding oral instructions, and understanding the audible items of the speech understanding scale.
