Support is requested for four lines of research, each of which extends previous studies of human listeners' abilities to process the acoustic details of complex sounds. (1) The limits of normal listeners' ability to discriminate nonspeech patterns will be further investigated, in tests of the Dimension Specific Capacity hypothesis, and in studies of the plasticity of listener's characteristics distribution of auditory attention. (2) Corresponding limits will be studied for speech stimuli, using natural and synthetic vowels. Listeners' abilities to resolve phoneme-relevant acoustic details will be determined for isolated vowels and vowels in sequences, under various levels of stimulus uncertainty. (3) Limits of spectral-temporal resolving power will be determined for hearing-impaired listeners, for speech and nonspeech complex stimuli. An effort will also be made to measure cross-modality (auditory, visual, tactile) temporal processing capabilities, and to determine whether those capabilities may explain differences in speech processing among audiometrically similar listeners. (4) Corresponding limits of processing will be determined for language-disordered children and young adults.

要求对四个研究领域提供支助， 扩展了先前对人类听者处理信息能力的研究 复杂声音的声学细节 (1)正常的极限 听众辨别非言语模式的能力将 进一步研究，在尺寸比容量的测试中 假设，并在研究的可塑性，听众的 听觉注意的特征分布。 （二） 相应的限制将研究语音刺激，使用 自然元音和合成元音。 听众的解决能力 音素相关的声学细节将被确定为孤立的 元音和元音序列，在不同水平的刺激下 不确定性 (3)频谱-时间分辨能力的限制将 为听障者，为说话者， 非言语复合刺激 还将努力衡量 跨通道（听觉、视觉、触觉）时间处理 能力，并确定这些能力是否可以 用听力学来解释 类似的听众。 (4)相应的处理限制将是 为语言障碍儿童和年轻人确定。
