Abstract: Studies in humans and monkeys have shown that small eye movements during fixation systematically vary with cued spatial attention. However, it remains unclear how these microsaccades relate to spatial attention in the absence of visual cues, which themselves impact microsaccade directions. Here, we investigated microsaccade properties of three macaque monkeys during learning of a blocked spatial attention task. Even without a visual cue immediately preceding each trial, microsaccade directions showed a clear dependency on the locus of spatial attention. We furthermore found that this relationship developed with learning of the task. Our results indicate that the link between microsaccades and spatial attention is subject to dynamic changes during training. Together, our findings provide further support for the view that microsaccades are meaningfully involved in cognition.
