在这项研究中，受试者的任务是识别一种节奏，它是插入两种节奏之间的一组模式中的一员：一种节奏是6/8节拍，另一种是4/4节拍。受试者首先学习不同模式与数字标签的一对一关联。然后，他们进行了一个完整的识别实验。这项任务的一个复杂之处在于，每次试验的克里思都是随机变化的。识别矩阵的分析，在相邻的节奏模式的可辨别性。有两个问题令人感兴趣。第一，是否可以区分一个节奏类别内的变化比机会和第二，是否歧视功能是非单调的，在节奏之间的边界处的峰值。结果表明，这两个问题的答案都是肯定的。
SummaryIn this study the task of the subject is to identify a rhythm which is a member of a set of patterns interpolated between two rhythms: One rhythm in a 6/8 and the other in a 4/4 metrum. The subjects first learn the one-to-one association of the different patterns with a numerical label. They then perform a complete identification experiment. One complication of the task is that the tempo varies randomly from trial to trial. The identification matrix is analyzed in terms of discriminability of neighboring rhythmic patterns. Two questions are of interest. First, whether variations within a rhythmic category can be discriminated better than chance and second, whether the discrimination function is nonmonotonic, with a peak at the boundary between the rhythms. The results indicate that the answer to both questions is positive.
