三项研究探讨了模仿几个周期性重复的简单的时间模式组成的2个或更多的时间间隔不同的持续时间比。60名本科生担任SS。学生在模仿中所犯的错误以及重复模仿过程中所发生的系统性变化表明，受过音乐训练和未经训练的学生都将时间序列映射到一个区间结构上，而区间结构的性质则通过研究哪些模式被正确地和不正确地再现而揭示出来。提出了一种基于节拍的时间序列感知模型。该模型指出，处理时间序列的第一步包括将序列分割成以事件为边界的相等间隔。这个间隔被称为”心跳间隔”（BI）。听众如何选择这个BI只是部分理解。在第二步中，小于BI的间隔表示为它们出现的BI的细分。然而，可以在模型中表示的心跳内结构的数量是有限的。具体而言，只有细分为相等间隔或以1：2比率拟合的间隔的BI才能在模型内拟合。提出的部分层次模型，虽然需要进一步的阐述，说明了为什么时间模式，可以正确地概念化的数量是有限的。(18参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Three studies investigated the imitation of several periodically repeating simple temporal patterns consisting of 2 or more intervals varying in their duration ratios. 60 undergraduates served as Ss. Errors that Ss typically made in their imitations and the systematic changes that occurred during repeated imitations indicated that both musically trained and untrained Ss mapped temporal sequences onto an interval structure the nature of which was revealed by studying which patterns were correctly and incorrectly reproduced. A" beat-based" model for the perception of temporal sequences is proposed. This model states that the 1st step in the processing of a temporal sequence consists of a segmentation of the sequence into equal intervals bordered by events. This interval is called the" beat interval"(BI). How listeners select this BI is only partly understood. In a 2nd step, intervals smaller than the BI are expressed as a subdivision of the BI in which they occur. The number of within-beat structures that can be represented in the model is, however, limited. Specifically, only BIs that are subdivided into either equal intervals or intervals in a 1: 2 ratio fit within the model. The partially hierarchical model proposed, though in need of further elaborations, shows why the number of temporal patterns that can be correctly conceptualized is limited.(18 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
