Research Abstract

Filling-in is a phenomenon by which a small figure (a filling-in target), which is presented in an observer's peripheral vision surrounded by a dynamic texture, is perceived to be invaded by the surrounding pattern and to disappear within a few seconds. Filling-in is regarded as a key to understanding the manner of effective visual information processing in human vision. Some characteristics of filling-in have been reported. Filling-in time has been adopted as a criterion of filling-in facilitation in many reports. From this perspective, we have proposed a model of the filling-in process that represents filling-in facilitation using filling-in target distinguishability from the surroundings. In this study, we first measures filling-in time for dynamic textures, surrounding a filling-in target. Those textures have various spatio-temporal frequencies. Furthermore, we estimated spatio-temporal frequency sensitivity of human vision at the retinal eccentricity where the filling-in target is projected. These results were applied to the filling-in process model. Results suggest that filling-in is facilitated when the LGN M-channel sensitivity is high ; it is inhibited when that of the LGN P-channel is great. We next examined the Influence of Small Eye Movement on Perceptual Filling-in Time. Results showed that the time to filling-in correlates moderately or weakly with eye movement, under the condition that complete fixation is achieved.
