Comparison of memory and meta-memory abilities of children with cochlear implant and normal hearing peers

Purpose. This study aimed (1) to compare visual memory and meta-memory abilities, including the use of strategies as context, of children with cochlear implant (CI) and children with normal hearing; (2) to examine the concurrent and construct validity of 'The Contextual Memory Test for Children' (CMT-CH). Method. Twenty children with CI and 20 children with normal hearing, aged 8-10 years, participated in this study. Memory abilities were measured by two subtests of the Children's Memory Scale (CMS) and by CMT-CH, which also measures meta-memory abilities. Results. Children with CI scored significantly lower in both tests of memory and meta-memory and showed less efficient use of context to memorise. Significant positive correlations were found between CMS and CMT-CH memory tests in both groups. Conclusions. Visual memory and meta-memory abilities may be impaired in children with CI. Evaluation and intervention for children with CI should refer to their memory and meta-memory abilities in order to measure the outcomes of CIs, and enhance language development academic achievements. Although more studies on CMT-CH should be performed, the CMT-CH may be used for the evaluation of visual memory of children with CI.
