| Outline of Final Research Achievements |
The aim of this study was to investigate how our brain compensates sensory uncertainty by combining multisensory information derived from an event, and by integrating the current sensory signal with the prior knowledge about the statistical structure of previous events.We measured the timing sensitivity and the central tendency for unisensory and multisensory stimuli with sensory uncertainty systematically manipulated by adding noise, and proposed computational models that indicate that the optimal multisensory integration precedes the Bayesian time estimation causing the central tendency. Our study suggested that the brain exploits the prior information stored at different processing stages adaptively in accordance with incoming sensory evidences.
