大量研究已经充分证明了对称知觉在视觉领域的重要作用。然而，不太清楚的是它作为音频领域格式塔分组原则的效果和潜在作用。我们使用一系列算法生成的声音来研究旋律对称性的可感知性。向 28 名天真的参与者提供了一系列九种对称的发音、九种部分对称的发音（大约一半的镜像元素发生了变化）和九种不对称的发音。参与者被要求将声音识别为属于这三个类别之一。声音处理利用了 Karplus-Strong 弦乐合成，持续时间在 500 到 8,000 毫秒之间。为了检查参与者的一致性，每个声音被呈现三次。尽管参与者的测试远接近于机会水平而不是完美的准确性，但我们观察到准确性和一致性测量的巨大影响。我们发现旋律中的音调数量对准确性有影响，包含更多音调的可听化更难以归因于正确的类别。持续时间较短和节奏较快的发声也被发现更难以准确归因，这表明旋律的一些最小持续时间以及构成旋律的各个音调。我们还发现了年龄对参与者的一致性有显着影响的证据，年龄较大的听众的表现更加一致。
The important role of symmetry perception in the visual domain has been well documented in a large number of studies. Less clear, however, is its effect and potential role as a Gestalt grouping principle in the audio domain. We investigated the perceptibility of melodic symmetry using a series of algorithmically generated sonifications. Twenty-eight naïve participants were presented with a series of nine symmetrical sonifications, nine partially symmetrical sonifications (with approximately half of the mirrored elements changed), and nine asymmetrical sonifications. The participants were asked to identify the sonifications as belonging to one of those three categories. The sonifications utilized Karplus-Strong string synthesis and had a duration between 500 and 8,000 ms. The sonifications were presented three times each in order to check for participants’ consistency. Although participants tested far closer to chance level than perfect accuracy, we observed large effect sizes on measures of both accuracy and consistency. We found an effect of the number of tones in a melody on accuracy, with sonifications containing more tones being more difficult to attribute to the correct category. Sonifications with shorter duration and a faster tempo were also found to be more difficult to attribute accurately, indicating some minimum duration of the melody as well as the individual tones constituting the melody. We also found evidence of a significant effect of age on participants’ consistency, with older listeners performing more consistently.
