The principles of cross-modal integration were investigated with an auditory-tactile illusion in sighted and congenitally blind adults. Participants had to judge the number of rapidly presented tactile stimuli, which were presented together with task-irrelevant sounds. When one tactile stimulus was accompanied by more than one tone, participants reported perceiving more than a single touch. This illusion was more pronounced in sighted than congenitally blind participants. Given that the congenitally blind were more precise in judging the number of tactile stimuli in a control condition without tones, the present data are in accordance with a modality-appropriateness account suggesting that interference by a task-irrelevant modality is reduced if processing accuracy of the task-relevant modality is high.
通过对视力正常的成年人和先天性盲人进行听觉-触觉错觉实验，研究了跨模态整合的原理。参与者需要判断快速呈现的触觉刺激的数量，这些触觉刺激与任务无关的声音同时呈现。当一个触觉刺激伴随着多个音调时，参与者报告感觉到的触摸次数不止一次。这种错觉在视力正常的参与者中比在先天性盲人中更明显。鉴于先天性盲人在没有音调的对照条件下判断触觉刺激数量时更准确，目前的数据符合一种模态适宜性解释，即如果任务相关模态的处理精度高，则任务无关模态的干扰会减少。
