“…These, in turn, produce illusions, such as the McGurk effect (McGurk & MacDonald, 1976), spatial or temporal ventriloquism (e.g., Bertelson, Vroomen, de Gelder, & Driver, 2000;Vroomen, Bertelson, & de Gelder, 2001;Vroomen & de Gelder, 2004), or the double-flash effect (Hötting & Röder, 2004;Shams, Kamitani, & Shimojo, 2000); but how intermodal binding actually works is still unclear. Multimodal perception (such as with audiovisual stimuli) faces binding problems that are far more complicated than within a single modality, due to the fundamental differences both in the physical properties of, say, sound and light and in the sensory transduction mechanisms (e.g., in transduction latencies, which prevent the use of tight temporal-synchrony criteria for crossmodal binding).…”
