一系列的6个实验探索了人类视觉比听觉的优势。对光的平均反应时间（RT）比对同时呈现的音调的平均反应时间快，即使刺激在主观强度上是相等的，即使单独呈现的音调的RT比单独呈现的光的RT快。当受试者不必对光作出反应时，当有光时，色调RT与没有光时相同或更快（感觉间促进）。音调的感觉或知觉加工不受光的影响，即视觉优势在位点上是非感觉的，取决于光刺激的相关性。这一解释得到了其他研究结果的支持，这些研究结果表明，视觉优势程度对光、色调和光加色调试验的可能性以及对特定模态的指示敏感，但对光的强度不敏感。
A series of 6 experiments explored the dominance of vision over audition in humans. Mean reaction time (RT) to a light was faster than to a simultaneously presented tone, even though the stimuli were equated in subjective intensity and even though RT to the tone presented alone was faster than to the light presented alone. When subjects did not have to respond to light, tone RT was equal or faster (intersensory facilitation) when a light was present than when it was not. Sensory or perceptual processing of the tone was not affected by the light, i.e., visual dominance was nonsensory in locus and depended on the relevance of the light stimulus. This interpretation was reinforced by other findings which showed that the degree of visual dominance was sensitive to the probability of light, tone and light-plus-tone trials and to instructions to attend to a specific modality, but was not sensitive to the intensity of the light.
