Abstract

We often misperceive some physical phenomena whose spatio-temporal properties may be beyond the ability of our given sensory system. When two sensory stimuli are presented in a short stimulus onset asynchrony (SOA), the perception of the preceding stimulus is influenced by the following stimulus. It is well known as the backward masking that can evoke misperception[1]. This is observed in visual, auditory and tactile perception. Backward masking is thought of as the phenomenon that the responses to the following stimulus influence those of the preceding stimulus inversely in the signal processing system.
