Aperture problem is a psychological experiment for analyzing binding mechanism of the spatial recognition in an early stage of visual path way. In this paper, we measure perceptual rate in the aperture experiments, and discuss the dependency between the perception and various parameters in the experiments. We also recorded Electroencephalograms (EEGs) of subjects who are recognizing the perception. By the EEG analysis, we measure reaction latency of the visual evoked potential (VEP) and the event rerated potential (ERP) related to visual pathway, and estimate the localized equivalent current dipole (ECD) in the visual pathway.
