"Investigating parafoveal processing during natural visual exploration and reading"
When we look at a scene or read, we move our eyes every 250 milliseconds. This means there is very little time between eye movements to process the fixated object, decide where to saccade next, and move the eyes. To better understand the brain mechanisms that support visual exploration and natural reading, we combined MEG and eye-tracking recordings. Participants were asked to explore multiple objects in a scene or read sentences while their brain activity and eye movements were recorded. By employing rapid-invisible frequency tagging and multi-variate pattern analysis, we found that words and objects being saccade goals are processed surprisingly fast at the semantic level. We also discovered that eye movements are phase-locked to ongoing alpha oscillations, which helps coordinate visual processing and saccades. Our findings rule out that our brains process words and objects in a strict serial or parallel fashion. Rather our results suggest that our brains employ a pipelining mechanism processing multiple objects or words simultaneously, but at different levels of processing hierarchy.
