Selectingsignals from differentsensory rnedalities

and bindingthernappropriately as asingle event are

necessar}r toensure a stable _perceptual world and to

guide appropriate actions tothe external world. To

do so, the brain is!ikelytouse both low-level

struc-turalfactorssuch as spatial cojncidence and

tempo-ral synchrony between the slgna]s, and cognitive

iactorssuch as semantic congruency. Research into

multisensory _perception has _grown spectacularly in

the lastdecade,and revealed that differentsensory

modalities are rnore closely related and mutually

interplayingthan classical views had assumed. The

airn of thissympesium was tohave a discussionof

the binding mechanisms of multisensory signals,

particularlyaddressing two topicsof continuing

in-terest:audio-visual interactionand the rnultimoda]

interactionon self-metion _perception,

We invitedthree distinguishedresearchers tothis

symposium. Dr. Mark E. McCaur't described the

al-terationof a tempora] window of audio-visual inter-actions dependent on stimulus intensity.Dr. Kenzo

Sakuraj introduced spatial and temporal ranges for audio-visual interactions inrnotion _perception, and

visual-vestibular interactionson headingperception,
