| Abstract(in English) | Attention is a perceptual function to choose useful information efficiently.In order to define the level of visual attention in the visual processing, we investigated the effects of attention on the detection threshold for the first-and second-order motions, which are assumed to process at different levels.In the experiment, the central stimulus was presented in the center to control the size of attention and the test stimulus(2×2 deg)was presented in the periphery, 4 deg away from the fixation.Subjects responded the motion of test stimulus with or without attending the central stimulus and we compared the motion sensitivities under these conditions.The results showed that absence of attention decreased the sensitivity for the second-order motion, but did not decrease the sensitivity for the first-order motion. |
