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）： 拟议的研究是制定最大化的评估和培训策略 成人和配有人工耳蜗（CL）的儿童的语音识别。 这项研究将集中于低于平均水平（差）的成年CL使用者 认可技能。它将利用联合行为的好处 和神经生理学方法来表征心理物理和言语 认可技能并构建个性化的培训策略。 具体目的是（1）评估密集心理物理的好处 训练; （2）评估强化语音识别培训的好处； （3）评估神经生理学与 心理物理反应和语音识别。 提出的实验的意义是证明在较差的 （即低于平均语音识别）成人CL用户，基本心理物理 通过密集型可以大大提高语音识别能力 训练。以前试图提高穷人的语音识别能力 适度的植入物用户充其量只能显示最小的成功。然而， 这些尝试的培训量极为有限。 更密集的培训计划可能会导致更大，更一致 语音识别的改善。在临床上，神经生理反应 例如听觉引起的潜力可能会提供重要的信息 用于指导和监视个性化的培训计划。从理论上讲， 这些结果将增加我们对中央听觉系统的理解 塑性和知觉的皮质过程和机制 学习。
