Adaptation minimizes distance-related audiovisual delaysHeron, James, Whitaker, David J., McGraw, Paul V., Horoshenkov, Kirill V. January 2007 (has links)
No / A controversial hypothesis within the domain of sensory research is that observers are able to use visual and auditory distance cues to maintain perceptual synchrony - despite the differential velocities of light and sound. Here we show that observers are categorically unable to utilize such distance cues. Nevertheless, given a period of adaptation to the naturally occurring audiovisual asynchrony associated with each viewing distance, a temporal recalibration mechanism helps to perceptually compensate for the effects of distance-induced auditory delays. These effects demonstrate a novel functionality of temporal recalibration with clear ecological benefits.
