| Abstract(in English) | The purpose of this study is to evaluate the effect of visual attention on the dynamics of fixation eye movements objectively. We carried out experiments which control the subjects' focal attention. A signal processing method was proposed to separate microsaccades and drift eye movements from fixation eye movements, and compared the properties of microsaccade rate and dynamics of drift eye movements among the conditions of atten-tional intensities. The results show that the microsaccade rate was suppressed and the histogram of latencies of microsaccades have two peaks when higher concentration was required. These results suggest that microsaccades are inhibited when attention is concentrated in foveal region, and disinhibited when attention is disengaged. On the other hand, drift eye movements were not influenced by the foveal attention allocation, rather affected by dif-fusing attention to the peripheral visual field, indicating that drift eye movements might be involved in the visual perception. |
