ReviewWhat you see is what you hear: Twenty years of research using the Sound-Induced Flash Illusion.
In the Sound-Induced Flash Illusion (SIFI) sound dramatically alters visual perception, as presenting a single flash with two beeps results in the perception of two flashes. In this comprehensive review, we synthesise 20 years of research using the SIFI, from over 100 studies. We discuss the neural and computational principles governing this illusion and examine the influence of perceptual experience, development, ageing and clinical conditions. ⋯ The SIFI shows increasingly strong potential as an efficient tool for measuring multisensory processing. Greater harmonisation across studies is now required to maximise this potential. We therefore propose considerations for researchers relating to choice of stimulus parameters and signpost directions for future research.
