Training enhances the ability of listeners to exploit visual information for auditory scene analysis

The ability to use temporal relationships between cross-modal cues facilitates perception and behavior. Previously we observed that temporally correlated changes in the size of a visual stimulus intensity an auditory influenced listeners perform selective attention task (Maddox, Atilgan, Bizley, & Lee, 2015). Participants detected timbral target sound while ignoring those simultaneously presented masker. When was coherent with sound, performance significantly better than when masker, despite conveying no task-relevant information. Here, trained observers detect audiovisual coherence asked whether this changed way which they were able exploit information task. We after training, participants benefit from both masker streams, relative condition neither sound. However, did not observe such second group discriminate modulation rate differences although show improvement their overall performance. A control change pretest post-test how exploited These results provide insights into crossmodal experience may optimize multisensory integration.
