Focusing or reallocating attention while actively fixating on the visual stimuli modulates the rate of microsaccades. However, little is known about the attentional modulation of the microsaccade rate in passive viewing. In this study, to investigate the properties of microsaccades induced by bottom-up attention, we conducted an experiment in which the subjects maintained visual fixation during passive viewing of randomly presented peripheral spotlights.
The brightness of the target in each experimental block was set to 4 intensity levels for each subject based on the discrimination threshold. Microsaccades were detected from the data and the microsaccade rate was analyzed for each condition. The results showed that around 300 ms after the onset of the target, transient inhibition and rebound responses of the occurrence of microsaccades were observed only in the conditions in which the subjects detected the
targets. This suggested that the existence of the rebound after inhibition of microsaccade occurrence showed the bottom-up attentional modulation of microsaccade generation and reflected the passive perception of peripheral visual events. |
