The long-term objective of this research is to gain a better understanding of the ability of deaf children to use specific types of sensory aids to acquire communication skills. The acquisition of these skills typically occurs slowly and imperfectly in deaf children. When children are totally deaf and cannot benefit from conventional hearing aids, access to the acoustic speech signal must be provided via a sensory aid that does not require cochlear function. Currently, two types of sensory aids are being used with these children: cochlear implants (CI) and vibrotactile aids (VT). The proposed research is designed to quantitate performance and to address fundamental issues related to device candidacy and efficacy. It is hypothesized that: (1) Multichannel CI and multichannel VT are superior to devices with a restricted number of channels in improving the speech perception abilities of totally deaf children who receive no benefit from conventional amplification. (2) The rate of acquisition of speech perception skills is faster with multichannel CI and VT than with a restricted number of channels. A battery of speech perception and language measures will be administered at 6 month intervals to validate these hypotheses. (3) Deaf children who have residual hearing demonstrate superior speech perception abilities with conventional hearing aids than totally deaf children who use a CI or VT. To test this hypothesis, hearing aid subjects will be tested longitudinally on the same measures used to assess the speech perception abilities of the children with CI or VT. (4) Deaf children who have residual hearing demonstrate superior speech perception skills when they have access to multimodal sensory information (auditory, tactual and visual) than when information is perceived via any of the modalities alone. The test measures used will be the same as above but the test conditions will be different. (5) Acoustic stimulation enhances visual attention and perception which promotes the development of cognitive and linguistic learning in deaf children who use CI and VT.

这项研究的长期目标是获得更好的理解 聋子使用特定类型的感官辅助工具的能力 获得沟通技巧。这些技能的获取通常 在聋哑儿童中缓慢而不完美地发生。当孩子们完全 聋哑，无法从传统的助听器中受益，访问 必须通过不的感官辅助提供声学信号 需要耳蜗功能。目前，有两种感觉辅助工具正在 与这些孩子一起使用：耳蜗植入物（CI）和纤维状AIDS （VT）。拟议的研究旨在量化性能和 解决与设备候选和功效有关的基本问题。 假设： （1）多通道CI和多通道VT优于带有A的设备 提高语音感知能力的频道数量有限 完全聋哑的孩子，他们没有从常规的人那里受益 放大。 （2）语音感知技能的获取速度的速度更快 多通道CI和VT比限制数量的通道数。电池 语音感知和语言措施将在6个月内进行管理 间隔以验证这些假设。 （3）有残留听证会的聋子表现出卓越的演讲 传统助听器的感知能力比完全聋哑 使用CI或VT的孩子。为了检验这一假设，助听器受试者 将以与评估相同的措施进行纵向测试 CI或VT儿童的语音感知能力。 （4）有残留听证会的聋子表现出卓越的演讲 感知技能可以访问多模式感官信息 （听觉，触觉和视觉），而不是通过任何信息来感知信息 单独的方式。所使用的测试措施将与上述相同 但是测试条件将有所不同。 （5）声学刺激增强了视觉注意力和感知 促进聋人认知和语言学习的发展 使用CI和VT的孩子。
