听觉格式塔知觉通过将物种特定的发声分组到具有定义意义的知觉流中，这是人类言语知觉的典型特征，但迄今尚未在非人类哺乳动物中进行研究。在这里，我们使用了老鼠幼崽（家鼠）的发声（一系列蠕动的叫声）的合成模型，并表明，如果叫声之间的间隔时间为100-400英寸，它们的母亲将叫声系列视为释放本能母性行为的有意义的格式塔。呼叫间隔较短或较长都会显著降低产妇的反应性。我们还发现，一系列自然蠕动叫声的叫声间间隔主要在100-400英寸范围内。因此，幼崽的一系列自然蠕动的叫声与它们母亲的时域听觉过滤器相匹配，以获得最佳的感知和识别。人类语言的产生和人类对一系列声音的感知也存在类似的时间窗口。讨论了设定时间窗口边界的神经机制。
Auditory Gestalt perception by grouping of species-specific vocalizations to a perceptual stream with a defined meaning is typical for human speech perception but has not been studied in non-human mammals so far. Here we use synthesized models of vocalizations (series of wriggling calls) of mouse pups (Mus domesticus) and show that their mothers perceive the call series as a meaningful Gestalt for the release of instinctive maternal behavior, if the inter-call intervals have durations of 100-400 ins. Shorter or longer inter-call intervals significantly reduce the maternal responsiveness. We also show that series of natural wriggling calls have inter-call intervals mainly in the range of 100-400 ins. Thus, series of natural wriggling calls of pups match the time-domain auditory filters of their mothers in order to be optimally perceived and recognized. A similar time window exists for the production of human speech and the perception of series of sounds by humans. Neural mechanisms for setting the boundaries of the time window are discussed.
