We thank Gerard B. Remijn for his helpful comments on an earlier version of our manuscript. This research was supported in part by a Grant-in-Aid for the 21st Century COE Program of Kyushu University entitled ‘Design of Artificial Environments on the Basis of Human Sensibility’, by a Grant-in-Aid for Young Scientists (B) (19730463) from the Japanese Ministry of Education, Culture, Sports, Science and Technology that was given to the author YA, and by a Grant-in-Aid for Scientific Research (S) (19103003) from the Japanese Ministry of Education, Culture, Sports, Science, and Technology that was given to Yoshitaka Nakajima. A portion of this study was presented at the Seventh Vision Sciences Society Annual Meeting (May 2007, Sarasota, Florida).

N2 - Two experiments examined whether filling-in occurred at the blind spot when a line segment was presented on only one side of the blind spot. We used static and dynamic stimuli: a static test line segment and a pair of probe line segments were presented in Experiment 1 and a moving test line segment was presented in Experiment 2. We compared the probability that the proximal end was perceived to be on the blind spot side when the test line segment came into contact with the blind spot (blind spot condition) with that when the test line segment was outside the blind spot (control condition). The results of the two experiments showed that the proximal end was perceived to be more on the blind spot side in the blind spot condition than in the control condition. Notably, when a dynamic stimulus was presented below the blind spot, the mean amount of filling-in reached 2.84°. Therefore, filling-in occurred at the blind spot even when a line segment was presented on only one side of the blind spot.
