| Outline of Final Research Achievements |
There has been intense debate over whether the perception of temporal order and the perception of simultaneity share a common mechanism. It has been believed that, when the interval of two sensory stimuli is short, people find it difficult to judge the temporal order and tend to perceive the stimuli as simultaneous. This study thus aimed to investigate whether the uncertainty of subjective temporal order and the subjective simultaneity occur independently. To this end, a series of psychophysics experiments were conducted using two visual stimuli that had different durations. The data showed that temporal order uncertainty is independent of the subjective simultaneity, suggesting that the subjective temporal order and the subjective simultaneity are processed by different mechanisms in the brain.
