本研究旨在探讨视听呈现对语篇理解的最佳时机。在实验1中，参与者被要求在三种条件下阅读和/或听到说明性段落;视觉呈现、听觉呈现和视听呈现条件。视听呈现条件下的理解成绩与视觉或听觉呈现条件下的理解成绩无显著差异，提示视听信息加工的认知负荷可能抵消了多通道呈现的积极作用。为了减少同时处理双重信息的负担，我们建议延迟两种模态呈现中的一种的时间，并在视听文本呈现期间将参与者的注意力引导到两种模态信息中的一种。在实验2至4中，通道提出了视听三种条件下，courageorily前，同时，和视觉前的条件。参与者被指示将他们的注意力集中在整个信息上（Exp. 2）、视觉信息（Exp. 3），和听觉信息（Exp. 4）。结果表明，当被试的注意力集中在整体信息或视觉信息上时，在视觉先行条件下的理解成绩更高。在此基础上，讨论了视听文本信息的整合过程。
This study investigates the optimal timing of audio-visual presentation for text comprehension. In Experiment 1, participants were asked to read and/or hear the expository passages in three conditions; visually presented, auditorily presented, and audio-visually presented condition. Comprehension performance in audio-visual presentation condition was not different from that in visual or auditory condition, raising the possibility that cognitive load on processing both visual and auditory information negated the positive effect of multi-modal presentation. To reduce the load of processing dual information simultaneously, we proposed to delay the timing of one of the two modality presentation and to direct participants’ attention to one of the two modality information during audio-visual text presentation. In Experiment 2 to 4, passages were presented audio-visually in three conditions; auditorily preceding, simultaneous, and visually preceding conditions. Participants were instructed to direct their attention to whole information (Exp. 2), visual information (Exp. 3), and auditory information (Exp. 4). The results showed that comprehension performance was higher in the visually preceding condition when their attention was directed whole or visual information. Based on the results, the integration process of audio-visually presented text information was discussed.
