对口语序列的即时记忆取决于它们的节奏--根据项目在时间上的间隔方式，可以看到不同水平的准确性和错误模式。目前的模型只能部分或根本不能解决这些现象。我们调查的想法，时间分组效应是一个新兴的属性的一般串行排序机制的基础上的人口振荡器本地敏感的幅度调制在不同的时间尺度。两个实验表明，时间分组的影响是独立的分组模式的可预测性，符合本模型的刺激驱动机制和自上而下的过程不一致的替代帐户。第二个实验报告了不规则分组序列的回忆中的详细和系统性差异，这些差异与新模型的预测大致一致。我们认为，自下而上的多尺度人口振荡器（或BUMP）机制是一个有用的起点，在语言处理更广泛的串行顺序的一般帐户。(C)2016 Elsevier Inc.

Immediate memory for spoken sequences depends on their rhythm - different levels of accuracy and patterns of error are seen according to the way in which items are spaced in time. Current models address these phenomena only partially or not at all. We investigate the idea that temporal grouping effects are an emergent property of a general serial ordering mechanism based on a population of oscillators locally-sensitive to amplitude modulations on different temporal scales. Two experiments show that the effects of temporal grouping are independent of the predictability of the grouping pattern, consistent with this model's stimulus-driven mechanism and inconsistent with alternative accounts in terms of top-down processes. The second experiment reports detailed and systematic differences in the recall of irregularly grouped sequences that are broadly consistent with predictions of the new model. We suggest that the bottom-up multi-scale population oscillator (or BUMP) mechanism is a useful starting point for a general account of serial order in language processing more widely.
