Abstract: The present research used the square and the triangle as visual stimuli and spoken words as auditory stimuli to investigate the effect of attention on multisensory speech integration. The visual and auditory stimuli were semantically congruent or incongruent. The results from a discrimination task showed that: 1) In the condition of divided attention, participants required less time to react to audiovisual semantic-congruent targets than other types of targets; that is the redundant signal effect; 2) According to the race model, the redundant signal effect in the condition of divided attention originated from the multisensory integration. To conclude, the multisensory integration occurred when the attention was divided between visual and auditory modality only in the semantic-congruent audiovisual stimuli.

Key words: attention, multisensory integration, semantic congruence, race model

摘要: 采用2×3的被试内实验设计,将注意条件和目标刺激类型作为实验变量,考察了指向不同感觉通道的注意对视听语义整合加工的不同影响。结果发现,只有在同时注意视觉和听觉刺激时,被试对语义一致的视听刺激反应最快,即产生冗余信号效应。而在选择性注意一个感觉通道时,语义一致的视听刺激并不具有加工优势。进一步分析发现,在同时注意视觉和听觉时语义一致视听刺激的加工优势源自于其视觉和听觉成分产生了整合。也就是说,只有在同时注意视觉和听觉时,语义一致视听刺激才会产生整合,语义不一致视听刺激不会产生整合。而在选择性注意一个感觉通道时,不论语义是否一致,视听刺激均不会产生整合。
