| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Accuracy of relative position judgments in vernier and bisection tasks declines rapidly with retinal eccentricity of the target position. It has been shown that the accuracy decline in vernier task is due partly to inefficiency of “perceptual template” of spatial frequency component, which determines the weight for each spatial frequency components in a stimulus image. Present study applied classification image technique to bisection task and investigated whether the change of perceptual template and "internal noise" which was estimated from response inconsistency caused the decline of position acuity with target eccentricity. We found that, in bisection task, internal noise increased with retinal eccentricity, while perceptual template was stable across eccentricities. | |
