The study also compared the&nbsp;memory performance of cochlear implanted children with their normal hearing peers.<br> <strong>Methods:</strong> Thirty-one cochlear implanted children with a mean age of 121.52 months (~10&nbsp;years) and SD=19.946 and 31 normal hearing children with a mean age 120.68 months (~10&nbsp;years) and SD=18.137 participated in this study. Their memory performance was assessed&nbsp;by Working Memory Test Battery for Children (1), speech perception was measured by&nbsp;Categories of Auditory Performance (2), and their speech production was assessed by Speech&nbsp;Intelligibility Rating (3). Finally, the data were analyzed using SPSS through its descriptive&nbsp;variables MANOVA and Spearman Correlation Coefficient.<br> <strong>Results:</strong> A significant and positive correlation was observed between working memory&nbsp;performance and cochlear implant outcomes. In addition, the children using cochlear implants&nbsp;had poorer performance compared to their normal hearing peers.<br> <strong>Discussion: </strong>This study demonstrated that the memory performance of children using cochlear&nbsp;implants has a significant effect on their speech production</p> Memory, Speech perception (CAP), Speech production (SIR), Working memory test battery for children (WMTB-C), Cochlear implant 35 42 http://irj.uswr.ac.ir/browse.php?a_code=A-10-201-7&slc_lang=en&sid=1 Soheyla Talebi s.talebi@ut.ac.ir Yes Department of Psychology of Exceptional Children, Faculty of Psychology & Education Sciences, University of Tehran, Tehran, Iran.
