这项研究评估了时间辨别任务中从视觉到听觉以及从听觉到视觉的训练可能产生的跨模式转移效应。我们采用了预测试-训练-后测试的设计，包括一个仅执行预测试和后测试的对照组。受过训练的参与者在训练间隔内表现出比对照组更好的辨别能力。这种训练效果仅适用于接受过听觉刺激训练的参与者。因此，本研究首次证明，听觉模态内的时间辨别训练可以转移到视觉模态，但反之则不然。这一发现代表了听觉在时间处理中的主导地位的新颖例证，并且与时间主要在听觉系统中编码的概念是一致的。
This study assessed possible cross-modal transfer effects of training in a temporal discrimination task from vision to audition as well as from audition to vision. We employed a pretest-training-post-test design including a control group that performed only the pretest and the post-test. Trained participants showed better discrimination performance with their trained interval than the control group. This training effect transferred to the other modality only for those participants who had been trained with auditory stimuli. The present study thus demonstrates for the first time that training on temporal discrimination within the auditory modality can transfer to the visual modality but not vice versa. This finding represents a novel illustration of auditory dominance in temporal processing and is consistent with the notion that time is primarily encoded in the auditory system.
