Abstract

Two cross-modal experiments provide partial support for O'Regan & Noë's (O&N's) claim that sensorimotor contingencies mediate perception. Differences in locating a target sound accompanied by a spatially disparate neutral light correlate with whether the two stimuli were perceived as spatially unified. This correlation suggests that internal representations are necessary for conscious perception, which may also mediate sensorimotor contingencies.
