Past research suggested that negative numbers could be represented in terms of their components in the visual modality. The present study examined the processing of negative numbers in the auditory modality and whether it is affected by context. Experiment 1 employed a stimuli detection task where only negative numbers were presented binaurally. Experiment 2 employed the same task, but both positive and negative numbers were mixed as cues. A reverse attentional spatial-numerical association of response codes (SNARC) effect for negative numbers was obtained in these two experiments. Experiment 3 employed a number classification task where only negative numbers were presented binaurally. Experiment 4 employed the same task, but both positive and negative numbers were mixed. A reverse SNARC effect for negative numbers was obtained in these two experiments. These findings suggest that negative numbers in the auditory modality are generated from the set of positive numbers, thus supporting a components representation.
过去的研究表明，负数可以在视觉模态中根据其组成部分来表示。本研究考察了负数在听觉模态中的处理方式以及它是否受语境影响。实验1采用了一个刺激检测任务，其中仅双耳呈现负数。实验2采用了相同的任务，但正数和负数混合作为线索。在这两个实验中均获得了负数的反向注意空间-数字反应编码关联（SNARC）效应。实验3采用了一个数字分类任务，其中仅双耳呈现负数。实验4采用了相同的任务，但正数和负数混合。在这两个实验中均获得了负数的反向SNARC效应。这些发现表明，听觉模态中的负数是从正数集合中生成的，从而支持了一种组成部分的表征方式。
