Visual Distractors Disrupt Audiovisual Integration Regardless of Stimulus Complexity.

摘要: The intricate relationship between multisensory integration and attention has been extensively researched in the field; however, necessity of for binding stimuli remains contested. In current study, we investigated whether diverting from well-known tasks would disrupt complexity stimulus task modulated this interaction. A secondary objective study was to investigate individual differences interaction integration. Participants completed a simple audiovisual speeded detection McGurk under various perceptual load conditions: no (multisensory while visual distractors present), low detecting presence yellow letter distractors), high number distractors). Consistent with prior studies, found that increased led decreased reports illusion, thus confirming speech stimuli. Although longer response times all task, participants responded faster on trials than unisensory trials. However, increase violated race model conditions only. Additionally, geometric measure Miller’s inequality showed decrease increasing load. Surprisingly, diverging changes who did not show condition: but increases task. results indicate plays crucial role both highly complex may interact differently processing individuals do strongly integrate information.
