Recognition of Perceptual Grouping and Localization of Brain Activity in Aperture Problems

Abstract

Aperture problem is an experiment for anlying the early motion processing in the visual pathway. Nishina argues the perception depends on the display time and discuss the processing of visual computation tasks. In this paper, we measure various perceptual rates in the same experiments, and discuss the dependency between the perception and the moving speed of stimulus lines. We also simultaneously record Electroencephalograms(EEG) of subjects who are recognizing the perception, and then estimate the source and the latencies in the brain.
