This study investigated the development of tense markers (e.g., past tense -ed) in children with cochlear implants (CIs) over a 3-year span. Nine children who received CIs before 30 months of age participated in this study at three, four, and five years postimplantation. Nine typical 3-, 4-, and 5-year- olds served as control groups. All children participated in a story-retell task. Percent correct of tense marking in the task was computed. Within the groups, percent correct of tense marking changed significantly in children with CIs and in typical children who had more hearing experience. Across the groups, children with CIs were significantly less accurate in tense marking than typical children at four and five years postimplantation. In addition, the performance of tense marking in children with CIs was correlated with their speech perception skills at earlier time points. Errors of tense marking tended to be omission rather than commission errors in typical children as well as in children with CIs. The findings suggested that despite the perceptual and processing constraints, children who received CIs may learn tense marking albeit with a delayed pattern.
本研究调查了人工耳蜗植入（CI）儿童在3年时间里时态标记（如过去式-ed）的发展情况。9名在30个月龄之前接受人工耳蜗植入的儿童在植入后3年、4年和5年参与了本研究。9名典型的3岁、4岁和5岁儿童作为对照组。所有儿童都参与了一个故事复述任务。计算了任务中时态标记的正确百分比。在这些组中，人工耳蜗植入儿童和有更多听力经验的典型儿童的时态标记正确百分比有显著变化。在不同组之间，人工耳蜗植入儿童在植入后4年和5年的时态标记准确性明显低于典型儿童。此外，人工耳蜗植入儿童的时态标记表现与他们早期的言语感知技能相关。在典型儿童以及人工耳蜗植入儿童中，时态标记错误往往是遗漏错误而非犯错错误。研究结果表明，尽管存在感知和处理限制，但接受人工耳蜗植入的儿童可能会学习时态标记，尽管模式有所延迟。
