Audiovisual integration in binaural, monaural and dichotic listening

• Audiovisual speech perception was investigated in three different conditions: (i) binaurally, where the same sound was presented in both ears, (ii) monaurally, where the sound was presented in one ear randomly, and (iii) dichotically, where the subjects were asked to focus on what was heard in the right ear. The results showed visual influence to be lowered in random monaural presentation as well as in dichotic presentation. Low visual influence to dichotic presentation, as compared with binaural presentation, supports the notion of an attentional component in audiovisual speech processing. Low visual influence in the random monaural presentation may be due to increased attention to the auditory modality because of uncertainty.
