This paper investigates how different types of data from psychoacoustical experiments may be combined to render further knowledge about the mechanisms underlying sound perception. Two studies were conducted with auditory alerts of short duration. First, an experiment where participants rated the dissimilarity among the auditory alerts was performed. This resulted in a two-dimensional multi-dimensional scaling solution. Second, an experiment where participants evaluated the stimuli with semantic descriptors and rated their emotional reactions to the sounds was performed. The output of this experiment was a reduced set of underlying perceptual and emotional dimensions. The results of the two experiments were then integrated by the use of multi-dimensional perceptual unfolding and a set mediation analyses. The integrative analyses showed that part of the cognitive categorization of the semantic descriptors was mediated by the emotional reactions to the sounds. The results are discussed in relation to theories of auditory perception and emotional response categorization.
本文研究了如何将来自心理声学实验的不同类型的数据结合起来，以进一步了解声音感知背后的机制。本研究进行了两项时长较短的听觉警报实验。首先，进行了一项参与者对听觉警报之间差异进行评分的实验。这得到了一个二维多维尺度的解决方案。其次，进行了一项参与者用语义描述符评估刺激并对声音的情绪反应进行评分的实验。该实验的输出是一组简化的潜在感知和情感维度。然后，通过多维感知展开和一系列中介分析来整合两个实验的结果。综合分析表明，语义描述符的部分认知分类是由对声音的情绪反应介导的。结果与听觉感知和情绪反应分类的理论进行了讨论。
