A computer model is described which simulates some aspects of auditory stream segregation. The model emphasizes the explanatory power of simple physiological principles operating at a peripheral rather than a central level. The model consists of a multi-channel bandpass-filter bank with a "noisy" output and an attentional mechanism that responds selectively to the channel with the greatest activity. A "leaky integration" principle allows channel excitation to accumulate and dissipate over time. The model produces similar results to two experimental demonstrations of streaming phenomena, which are presented in detail. These results are discussed in terms of the "emergent properties" of a system governed by simple physiological principles. As such the model is contrasted with higher-level Gestalt explanations of the same phenomena while accepting that they may constitute complementary kinds of explanation.
本文描述了一个模拟听觉流分离某些方面的计算机模型。该模型强调了在周边而非中枢层面起作用的简单生理原理的解释力。该模型由一个具有“噪声”输出的多通道带通滤波器组和一个对活动最强的通道进行选择性响应的注意力机制组成。“泄漏积分”原理允许通道兴奋随时间积累和消散。该模型产生的结果与两个详细呈现的流现象实验演示相似。这些结果根据由简单生理原理支配的系统的“涌现特性”进行了讨论。因此，该模型与对相同现象的高级格式塔解释形成对比，同时承认它们可能构成互补的解释类型。
