the first and second sound is shortened, listeners are unable to distinguish between the two sounds. Instead, they perceive them as both coming from the location of the lead sound. This effect counteracts the small disparity between the perception of sound caused by the difference in distance between each ear and the source of the auditory stimuli. The interaction between auditory and visual cues There are strong interactions between visual and auditory stimuli. Since both auditory and visual cues provide an accurate source of information about the location of an object, most times there will be minimal discrepancy between the two. However, it is possible to have a disparity in the information provided by the two sets of cues. An example of visual capture is the ventriloquism effect, that occurs when an individual's visual system locates the source of an auditory stimulus at a different position than where the auditory system locates it. When this occurs, the visual cues will override the auditory ones. The individual will perceive the sound as coming from the location where the object is seen. Audition can also affect visual perception. Research has demonstrated this effect by showing two objects on a screen, one moving diagonally from top-right to bottom-left and the other from top-left to bottom-right, intersecting in the middle. The paths of these identical objects could have been interpreted as crossing over each other, or as bouncing off each other. Without any auditory cue, a vast majority of subjects saw the objects crossing paths and continuing in their original trajectory. But with the addition of a small "click" sound, a majority of subjects perceived the objects as bouncing off each other. In this case, auditory cues help interpret visual cues. Haptic cues A haptic cue is either a tactile sensation that represents an incoming signal received by the somatic system, or a relationship between tactile sensations which can be used to infer a higher level of information. The results of receiving and processing these cues are collectively known as the sense of touch, and are the subject of research in the fields of psychology, cognitive science, and neurobiology. The word "haptic" can refer explicitly to active exploration of an environment (particularly in experimental psychology and physiology), but it is often used to refer to the whole of the somesthetic experience. Somatosensory system The somatosensory system assimilates many kinds of information from the environment:
