Eye Movements in Visual Duration Perception: Disentangling Stimulus from Time in Predecisional Processes

We are trying to understand the mechanisms linking time perception abilities with reading skills. Here you ask a more specific question. What explains the relation between perceiving the time structure of a visual stimuli and reading skills?

Is this association real? Instead, it is a byproduct of visual processing problems in dyslexia. The temporal sampling framework was a breakthrough in this area by proposing that the synchronization of brainwaves with auditory stimuli was necessary to receive both sequence and speech unities.

Associations between time perception for visual stimuli and reading have also been reported, but explanations are still lacking. Major challenge when you study time perception for visual stimuli is characterizing the cognitive processes that take place during stimulus presentation. Eye tracking is a candidate too.

But one problem is that the ocular model response do not reflect time perception only, and also reacts to stimulus characteristics like luminance. In this study, we present an eye tracking protocol that allow us separating oculomotor indices of stimulus processing from potential indices of time perception.
