Abstract: Amblyopia is a neurodevelopmental disorder associated with reduced vision in one or both eyes, caused by abnormal visual experience during early childhood. The sound-induced flash illusion is a task in which flashes and sounds are presented concurrently, and the number of sounds influences the number of perceived flashes. This study examines the temporal binding window of audiovisual integration in amblyopia using the sound-induced flash illusion at different stimulus onset asynchronies of flashes and sounds. Eleven participants with amblyopia and sixteen visually normal controls were tested on the sound-induced flash illusion. Participants with amblyopia were equally susceptible to the illusion as controls, and showed a widening of the temporal binding window on the "fission" subset of the illusion (two sounds, one flash, percept of two flashes) when viewing binocularly and when the sounds precede the flash. This binocular-specific difference implies potential abnormal temporal integration in real-world situations.
