Recent studies show that the mechanism responsible for the occurrence
of microsaccades, which are small involuntary shifts in the eye-gaze
position, is related to the visual attention system. These studies
report that the microsaccade rate increases with shift of attention
allocation. In contrast, other studies show that the occurrence of
microsaccades is inhibited when visual attention is intensely applied
on a fixed target. It has not yet been established as to which of
these conclusions is correct. In this study, we hypothesized that
microsaccade rate decreases with the degree of attentional
concentration. Subjects performed RSVP tasks with instructions to
maintain their fixation on the alphabet characters which were
displayed on the center of a CRT monitor. The degree of attention
engagement of the subjects was controlled by changing the contrast of
target characters. Then we analyzed the relationship between the
microsaccade rate and the degree of attention engagement. The results
show that the microsaccade rate was suppressed from just before the
target objects were displayed, and increased after the target was
extinguished. When higher concentration was required, this inhibition
of microsaccade occurrence was prolonged. These results suggest that
the microsaccade rate is inhibited with the concentration of visual
attention in the foveal region. |
