ABSTRACT

The study aimed to improve sequential time perception among deaf and hard-of-hearing (DHH) children with and without cochlear implants (CIs) by administering an intervention programme using virtual-reality (VR) technology. The study included 55 children 7–10 years old who were divided into 3 groups: DHH children with CIs, DHH children without CIs, and a control group of typically-hearing children. Pre- and post- the intervention (8 weekly individual meetings), participants completed a sequential time measure. Results indicated that at pre-intervention, DHH children demonstrated less sequential time perception compared to typically-hearing children. Following the intervention, both research groups demonstrated significant improvement in sequential time perception. However, the improvement was much more significant in the group of children without CIs. Moreover, DHH children who received implants after the age of language acquisition (postlingually) showed a greater improvement in this measure compared to children who received implants prior to the age of language acquisition (prelingually).

摘要

该研究旨在通过使用虚拟现实 (VR) 技术实施干预计划，改善有和没有人工耳蜗 (CI) 的聋哑和听力障碍 (DHH) 儿童的顺序时间感知。该研究包括 55 名 7-10 岁的儿童，他们分为 3 组：患有 CI 的 DHH 儿童、没有 CI 的 DHH 儿童和正常听力儿童的对照组。在干预前后（每周 8 次单独会议），参与者完成了一个连续的时间测量。结果表明，与听力正常的儿童相比，DHH 儿童在干预前表现出较少的顺序时间感知。干预后，两个研究组都表现出连续时间感知的显着改善。然而，在没有 CI 的儿童组中，改善更为显着。此外，与在语言习得年龄（语前）之前接受植入物的儿童相比，在语言习得年龄（语后）之后接受植入物的 DHH 儿童在此测量中表现出更大的改善。
