What you see is what you hear

It is shown that auditory information can qualitatively alter the perception of an unambiguous visual stimulus to create a striking visual illusion, indicating that visual perception can be manipulated by other sensory modalities.

Abstract

Vision is believed to dominate our multisensory perception of the world. Here we overturn this established view by showing that auditory information can qualitatively alter the perception of an unambiguous visual stimulus to create a striking visual illusion. Our findings indicate that visual perception can be manipulated by other sensory modalities.
