| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This study investigated how human’s spatial attention changes to cover different sizes of visual stimuli. We measured Steady-State Visual Evoked Potentials (SSVEP) to each of four different sizes of concentric rings flickering at different frequencies (SSVEP frequencies). The participant was instructed to attend to one of four sizes to detect a target stimulus in sequences of numbers presented rapidly (4 times per second) for four seconds, during which EEG signals were recorded. Frequency analysis showed clear peaks at each of four SSVEP frequencies, which was influenced by attention condition, suggesting a clear attention effect for stimulus sizes. SSVEP for each of four stimuli with different sizes as a function of attended size showed the largest amplitude when that stimulus was attended, with decreasing with difference in size between the stimulus and the attended size. The present experiment revealed that visual attention changes its size to cover the area of stimulus target, and that there are enhancement and inhibition effects in size of visual attention. | |
