# Audio-Visual Objects **Opening (not a real abstract):** [A fire is] a terrestrial event with flames and fuel. It is a source of four kinds of stimulation, since it gives off sound, odor, heat and light . . . .

For this event, the four kinds of stimulus information and the four perceptual systems are equivalent. If the perception of fire were a compound of separate sensations of sound, smell, warmth and color, they would have had to be associated in past experience in order to explain how any one of them could evoke memories of all the others. . . . [T]he problem of perception is not how sensations get associated; it is how the sound, the odor, the warmth, or the light that specifies fire gets discriminated from all the other sounds, odors, **Authors:** [[Kubovy and Schutz]]
