这一系列实验处理了两种不同的时间模式之间的区别，只是插入了一个额外的沉默间隙。在实验1中，图案在节拍和图形结构上有所不同。韵律结构被描述为主观重音之间可能出现的时间规律感。比喻结构被描述为由无声隔开的时间上相邻的音调的分组。标准模式要么是强的，要么是弱的；比较模式与标准的不同之处在于，插入了沉默，要么单独破坏了量度结构，要么同时扰乱了量度结构和比喻结构。实验1支持度量结构和比喻结构的作用，并支持Povel和Essens(1985)的时钟感应模型作为度量加工的解释。在实验2-4中，对具有不同音阶结构但相同图形结构的图案的辨别进行了更仔细的考察。图案的呈现速度是不同的。多元回归表明，与频率变化无关，辨别力随着沉默差距的绝对(而不是相对)持续时间的增加而改善。我们认为，一种与模式结构无关的额外的计时机制在时间模式辨别中是有效的。所有的结果都在听众的音乐训练水平上得到了复制。
This series of experiments dealt with discrimination between two temporal patterns differing only by the insertion of an additional silent gap. In Experiment 1, patterns varied in metric and figural structure. Metric structure is described as the sense of temporal regularity that may occur between subjectively accented tones. Figural structure is described as the grouping of temporally adjacent tones separated by silences. Standard patterns were either strongly or weakly metric; comparison patterns differed from the standards by the insertion of a silence that disrupted either the metric structure alone or both the metric and the figural structures. Experiment 1 provided support for the roles of both metric and figural structures and provided support for the clock-induction model of Povel and Essens (1985) as an account of metric processing. In Experiments 2-4, discrimination of patterns with differing metric structures but identical figural structures was examined more closely. Rate of presentation of the patterns was varied. Multiple regression indicated that, independent of rate variations, discrimination improved as the absolute (not relative) duration of the silent gap increased. We argue that an additional timing mechanism, independent of pattern structure, is operative in temporal pattern discrimination. All the results were replicated across levels of music training of the listeners.
