ABSTRACT
The literature is replete with examples in which information in one sense changes perception in another. Specifically, a visual cue can significantly alter one’s judgments about proprioceptive and auditory cues, and proprioceptive cues can bias judgments regarding the location of an auditory stimulus (Held, 1955; Pick, Warren, & Hay, 1969; Shelton & Searle, 1980; Thurlow & Rosenthal, 1976; Warren, Welch, & McCarthy, 1981; Welch & Warren, 1980). For example, the magnitude of intersensory influences is made quite evident when watching some of the films now shown in planetariums. One that was played at the theater in the Science Museum of Virginia simulated the visual cues one would experience in an Alaskan bush plane flying through a rugged mountain range. The vestibular sensations initiated by the rapidly shifting visual images were quite vivid, and the secondary gastrointestinal changes they produced were ever so real.
