DISCRIMINATION AND IDENTIFICATION OF AUDITORY PATTERNS

请求为四项研究提供支助，每项研究 扩展了之前对人类听者处理能力的研究 复杂声音的声学细节。(1)正态的界限 听众辨别非言语模式的能力将是 进一步研究，在维度比容量测试中 假说，以及在对听者可塑性的研究中 听觉注意的特点和分布。(2) 将研究语音刺激的相应限制，使用 自然元音和合成元音。听者解决问题的能力 将确定与音素相关的声学细节 在不同刺激水平下，元音和元音按顺序排列 不确定性。(3)光谱-时间分辨率的极限 被确定为听力受损的听众、言语和 非语音复合刺激。还将努力测量 跨通道(听觉、视觉、触觉)时间加工 功能，并确定这些功能是否可以 解释不同测听方法在语音处理方面的差异 相似的听众。(4)相应的加工限额为 为语言障碍儿童和年轻人确定的。

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.
