项目摘要

To perceive a sequence of tones as a "melody, " two perceptual processes are essential ; a process for evaluating the metrical organization and a process for evaluating the tonal organization of the sequence. The former assigns a coherent temporal structure on the tone sequence and, as a result, such psychological time units as "beat" and "meter" are perceived. Similarly, processing dedicated to the tonal organization assigns coherence to the relationship between the pitches of the individual notes in the sequence thus conferring a sense of "tonality" upon the sequence. The perceptual processes devoted to the metrical and tonal relationships are considered to comprise independent modules. Nevertheless, there is no doubt that the outputs of the two processing modules are integrated, in some way, at some stage of processing. The present study aimed at clarifying the inter-relationship between the two kinds of perceptual processing, i.e., the metrical organization and the tonal organization. We engaged in cognitive modeling of processes involved in the tonal organization and the metrical organization, assuming that they are independent modules. We constructed computer models that were capable of predicting the assignment of "key" of a given tone sequence and the degree of the "keyness, " using only pitches of the constituent notes as data. Our model was found to predict approximately 80% of listeners' key interpretations in a comparison between the results of our simulation study and the recorded responses from the subjects of our experiment. This result is superior to the fits obtained by our implementing programs of any other existing models. We also constructed a computer model that was capable of interpreting the beat and meter of a given tone sequence using only tone-lengths of the constituent notes.

为了将音调序列感知为“旋律”，两个感知过程是必不可少的；一种评价音律组织的过程和评价音序的调性组织的过程。前者在音调序列上分配了连贯的时间结构，因此可以感知到“拍”和“拍子”等心理时间单位。同样地，专门用于音调组织的处理将序列中单个音符的音高之间的关系赋予连贯性，从而赋予序列一种“调性”感。致力于韵律和音调关系的感知过程被认为是由独立的模块组成的。然而，毫无疑问，在处理的某个阶段，两个处理模块的输出以某种方式是集成的。本研究旨在阐明两种知觉加工，即格律组织和调性组织之间的相互关系。我们对声调组织和格律组织的过程进行了认知建模，假设它们是独立的模块。我们构建了能够预测给定音调序列的“键”分配和“键度”程度的计算机模型，仅使用组成音符的音高作为数据。通过对比我们的模拟研究结果和实验对象的记录回答，我们发现我们的模型可以预测大约80%的听众的关键解释。这一结果优于我们的实现程序所得到的任何其他现有模型的拟合结果。我们还构建了一个计算机模型，该模型能够仅使用组成音符的音长来解释给定音调序列的节拍和节拍。
