对亚秒时间尺度中的时间模式的感知是对话、音乐感知和其他类型的声音交流的基础。然而，其作用机制尚不完全清楚。一个简单的例子是听到三个连续的短时间间隔的声音。人们对后一种区间的误解如下：当前者比后者略短或更长时，低估后者；当前者比后者略长或更短时，高估后者。虽然这种对简单刺激的听觉时间间隔的误解可能是理解时间间隔知觉机制的线索，但目前还没有全面解释它的模型。考虑到先前的实验表明，不同频率的刺激声音不会产生幻觉知觉，我们可能会认为，时间间隔知觉的潜在机制涉及对声源的因果推断：在这里，不同的频率为不同的原因提供线索。我们构建了这种时间间隔感知的贝叶斯观测器模型。我们在模型中引入了一个概率变量来表示声音的因果关系。作为先验知识，观察者假设单个声源产生周期性和短时间间隔，这与以前的几个工作一致。我们进行了数值模拟，证实了我们的模型可以再现听觉时间间隔的错误感知。类似的现象在视觉和触觉模式中也有报道，尽管它们的时间范围更广。这表明存在一种共同的机制，即时间模式知觉优于通道。这是因为这些不同的属性可以被解释为时间分辨率的差异，因为视觉和触觉的时间分辨率低于听力的时间分辨率。
Perception of a temporal pattern in a sub-second time scale is fundamental to conversation, music perception, and other kinds of sound communication. However, its mechanism is not fully understood. A simple example is hearing three successive sounds with short time intervals. The following misperception of the latter interval is known: underestimation of the latter interval when the former is a little shorter or much longer than the latter, and overestimation of the latter when the former is a little longer or much shorter than the latter. Although this misperception of auditory time intervals for simple stimuli might be a cue to understanding the mechanism of time-interval perception, there exists no model that comprehensively explains it. Considering a previous experiment demonstrating that illusory perception does not occur for stimulus sounds with different frequencies, it might be plausible to think that the underlying mechanism of time-interval perception involves a causal inference on sound sources: herein, different frequencies provide cues for different causes. We construct a Bayesian observer model of this time-interval perception. We introduce a probabilistic variable representing the causality of sounds in the model. As prior knowledge, the observer assumes that a single sound source produces periodic and short time intervals, which is consistent with several previous works. We conducted numerical simulations and confirmed that our model can reproduce the misperception of auditory time intervals. A similar phenomenon has also been reported in visual and tactile modalities, though the time ranges for these are wider. This suggests the existence of a common mechanism for temporal pattern perception over modalities. This is because these different properties can be interpreted as a difference in time resolutions, given that the time resolutions for vision and touch are lower than those for audition.
