A model of audio-visual motion integration during active self-movement.

ABSTRACT: Despite good evidence for optimal audio-visual integration in stationary observers, few studies have considered the impact of self-movement on this process. When the head and/or eyes move, the integration of vision and hearing is complicated, as the sensory measurements begin in different coordinate frames. To successfully integrate these signals, they must first be transformed into the same coordinate frame. We propose that audio and visual motion cues are separately transformed using self-movement signals, before being integrated as body-centered cues to audio-visual motion. We tested this hypothesis using a psychophysical audio-visual integration task in which participants made left/right judgments of audio, visual, or audio-visual targets during self-generated yaw head rotations.
