The aim of the present study is to determine which acoustic components of harmonic consonance and dissonance influence automatic responses in a simple cognitive task. In a series of affective priming experiments, eight pairs of musical intervals were used to measure the influence of acoustic roughness and harmonicity on response times in a word-classification task conducted online. Interval pairs that contrasted in roughness induced a greater degree of affective priming than pairs that did not contrast in terms of their roughness. Contrasts in harmonicity did not induce affective priming. A follow-up experiment used detuned intervals to create higher levels of roughness contrasts. However, the detuning did not lead to any further increase in the size of the priming effect. More detailed analysis suggests that the presence of priming in intervals is binary: in the negative primes that create congruency effects the intervals' fundamentals and overtones coincide within the same equivalent rectangular bandwidth (i.e., the minor and major seconds). Intervals that fall outside this equivalent rectangular bandwidth do not elicit priming effects, regardless of their dissonance or negative affect. The results are discussed in the context of recent developments in consonance/dissonance research and vocal similarity.

对音程的自动响应：声学粗糙度的对比预测西方听众的情感启动

本研究的目的是确定谐和和不谐调的哪些声学成分会影响简单认知任务中的自动反应。在一系列情感启动实验中，在在线进行的单词分类任务中，使用八对音程来测量声学粗糙度和和谐度对响应时间的影响。与在粗糙度方面没有对比的对相比，在粗糙度方面形成对比的间隔对诱导了更大程度的情感启动。和谐性的对比不会诱发情感启动。后续实验使用失谐间隔来创建更高水平的粗糙度对比度。然而，失谐并没有导致启动效应的大小进一步增加。更详细的分析表明，音程中的启动是二元的：在产生一致性影响的负素数中，音程的基本和泛音在相同的等效矩形带宽内重合（即，小秒和大秒）。落在此等效矩形带宽之外的间隔不会引起启动效应，无论它们的失调或负面影响如何。这些结果在谐和/不谐和研究和声音相似性的最新发展的背景下进行了讨论。不管他们的不和谐或负面影响。这些结果在谐和/不谐和研究和声音相似性的最新发展的背景下进行了讨论。不管他们的不和谐或负面影响。这些结果在谐和/不谐和研究和声音相似性的最新发展的背景下进行了讨论。
