这项研究的目的是更好地了解人们对 复杂的听觉刺激。实现这一目标的手段是 通过考虑声学刺激的表示，并且在 特别是时间表征与时间表征之间的关系 声学刺激的强度方面。这些实验是 设计的目的是，一小时和一小时，确定是否处理 作为独立编码方式的时间和强度信息 其中时间和强度信息被独立编码 能够解释心理物理数据，另一方面， 检查时间和强度信息的方式 在时间或强度信息上进行组合。一秒钟 实验操作需要区分复杂的声音 在三个特征方面有系统地变化：强度、包络 调制和相位调制。区分不同性别的能力 这样的刺激允许估计这些的相对贡献 用于形成复杂的听觉感知的特征，并允许 对表示这些要素的方法的初步评估 在听觉系统中。关于时间和时间的基本信息 这将导致听觉系统中的强度处理 研究计划可为临床诊断和治疗提供依据。 听力受损。尤其重要的是开发一种 时间和强度处理可以独立进行的手段 测试过。

The objective of this research is to better understand the perception of complex auditory stimuli. The means by which this is to be achieved is by consideration of the representation of acoustical stimuli, and in particular the relationship between the representation of temporal and intensity aspects of the acoustical stimuli. The experiments are designed to, one the one h and, determine whether models which treat temporal and intensity information as being independently coded manner in which temporal and intensity information as being independently coded are able to account for psychophysical data, and on the other hand, examine the manner in which temporal and intensity information is combined both on either temporal or intensity information. A second experimental manipulation requires discriminations between complex sounds that vary systematically in terms of three features: intensity, envelope modulation and phase modulation. The ability to discriminate between such stimuli allows an estimation of the relative contribution of these features for the formation of complex auditory percepts, and allows an initial evaluation of the means by which these features are represented in the auditory system. The basic information concerning temporal and intensity processing in the auditory system that will result from this plan of study may provide a basis for the diagnosis and treatment of auditory impairment. Particularly important is the development of a means by which temporal and intensity processing may be independently tested.
