Abstract : Sensory interaction occurs when the response elicited by a sense modality due to a specific stimulus is significantly affected by the simultaneous stimulation of that sensory system by any other sense modality in the body. This experiment is concerned with the interaction of audition and vision where the auditory conditions consist of no sound, pleasant sound, and unpleasant sound (as judged by the subject), and the visual conditions consist of equal intensity judgments on red, green and blue lights against a white standard. The data from thirty subjects are discussed including main effects and interaction of experimental conditions. The hypotheses concerning the differential sensitivity of the dark-adapted eye to red, green and blue colored lights are confirmed. The hypotheses concerning the influence of audition on vision are not confirmed. The potential influence of the reticular activating system is discussed in light of these findings. (Author)
