EARLY EXPERIENCE AND DEVELOPMENT OF HEARING

描述：(改编自申请人的摘要。)很大一部分是 对成熟人类听力的了解，但相对较少 早期的经历如何影响这些重要的能力。特别是 关于我们如何感知复杂的模式，我们知之甚少 声音，是正常注意力和交流的重要组成部分。这 研究量化了早期传导性听力损失在 听力发育。这些研究利用了一个独特的人群 在仔细的心理声学或心理声学组合中 感觉实验，以及更多的综合性或认知性实验， 探索我们如何学会欣赏复杂结构中的相关句型 听起来。 天生具有最大传导性听力损失的患者将使用 在不同的年龄进行手术矫正和双耳处理 这些合作主体的新耳朵将被使用。假设是为了 被评估的是听力的不同方面(称为 侦测、干扰、辨别、双感觉整合和 属性)独立出现。看起来早期的 “剥夺”导致了一个有趣的缺陷 简单的图案。数据将提供新的和有凝聚力的 观察我们的感知是如何变得有组织和有组织的。 这一结果将对 对听力和沟通障碍的认识和治疗 关于知觉障碍的一般理论。

DESCRIPTION:(Adapted From The Applicant's Abstract.) A great deal is known about the hearing of mature humans, but relatively little about how early experience affects these important abilities. In particular little is known about how we come to perceive patterns in complex sounds, an essential part of normal attention and communication. This research quantifies the roles of early conductive hearing loss on hearing development. The studies take advantage of a unique population of human patients in a combination of careful psychoacoustical or sensory experiments, and more integrative or cognitive experiments, to discover how we learn to appreciate relevant patterns in complex sounds. Patients born with a maximum conductive hearing loss will be used which is surgically corrected at different ages and binaural processing in the "new" ear of these cooperative subjects will be used. The hypothesis to be evaluated is that different aspects of hearing (termed detections, distractions, discriminations, bisensory integration,and attributes) emerge independently. It appears that the early "deprivation" leads to an interesting deficit in the perception of simple patterns. The data will provide new and cohesive observations on how our perceptions become structured and organized. The results will have far-reaching implications for the understanding and treatment of hearing and communication disorders and for general theories of perceptual disorders.
