DESCRIPTION: (Adapted from applicant's abstract): The long-term goal of the proposed study is to develop assessment and training strategies that maximize speech recognition in adults and children fitted with a cochlear implant (Cl). This study will focus on adult Cl users with lower than average (poor) speech recognition skills. It will capitalize on the benefits of a combined behavioral and neurophysiological approach to characterize psychophysical and speech recognition skills and construct individualized training strategies. The specific aims are to (1) evaluate the benefit of intensive psychophysical training; (2) evaluate the benefit of intensive speech recognition training; and (3) evaluate the correlations between the neurophysiological and psychophysical responses, and speech recognition. The significance of the proposed experiments is the demonstration that in poor (i.e., below average speech recognition) adult Cl users, basic psychophysical and speech recognition skills can be improved significantly by intensive training. Previous attempts to improve the speech recognition abilities of poor to moderate implant users have shown, at best, only minimal success. However, these attempts have been extremely limited in the amount of training provided. More intensive training programs may result in larger, more consistent improvements in speech recognition. Clinically, neurophysiological responses such as auditory evoked potentials may provide important information that can be used to guide and monitor individualized training programs. Theoretically, these results will increase our understanding of central auditory system plasticity and the cortical processes and mechanisms involved in perceptual learning.

描述：（改编自申请人的摘要）：该项目的长期目标 拟议的研究旨在制定评估和培训策略，最大限度地提高 装有人工耳蜗的成人和儿童的语音识别（Cl）。 这项研究将重点关注言语低于平均水平（较差）的成年 CI 用户 识别能力。它将利用综合行为的好处 和神经生理学方法来表征心理物理和言语 识别技能并构建个性化培训策略。 具体目标是（1）评估强化心理物理的益处 训练; (2)评估强化语音识别训练的效益； (3)评估神经生理学和神经生理学之间的相关性 心理物理反应和语音识别。 所提出的实验的意义在于证明了在贫困的情况下 （即低于平均语音识别）成人 Cl 用户，基本心理物理学 通过强化训练可以显着提高语音识别能力 训练。先前尝试提高穷人的语音识别能力 至中等程度的植入物使用者充其量只取得了最小的成功。然而， 这些尝试所提供的培训数量极其有限。 更密集的训练计划可能会带来更大、更一致的结果 语音识别方面的改进。临床上，神经生理反应 例如听觉诱发电位可能提供重要信息 用于指导和监控个性化培训计划。理论上， 这些结果将增加我们对中枢听觉系统的理解 可塑性以及参与知觉的皮质过程和机制 学习。
