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).
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.
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.
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.
本研究旨在：(1)比较患有人工耳蜗（CI）和正常听力儿童的视觉记忆和元记忆能力，包括使用上下文等策略；(2)检验“儿童语境记忆测验”（CMT-CH）的同时效度和结构效度。
20 名 8-10 岁的 CI 儿童和 20 名正常听力儿童参加了本研究。通过儿童记忆量表（CMS）的两个子测验和 CMT-CH 来测量记忆能力，CMT-CH 还测量元记忆能力。
CI 儿童在记忆和元记忆测试中得分明显较低，并且在使用上下文进行记忆方面效率较低。在两个组中，CMS 和 CMT-CH 记忆测试之间都存在显著的正相关。
CI 儿童的视觉记忆和元记忆能力可能受损。对 CI 儿童的评估和干预应参考其记忆和元记忆能力，以衡量 CI 的效果，并促进语言发展和学业成就。尽管应该对 CMT-CH 进行更多的研究，但 CMT-CH 可用于评估 CI 儿童的视觉记忆能力。
