Pre-target oculomotor inhibition reflects temporal orienting rather than certainty

Abstract Recent studies suggested that eye movements are linked to temporal predictability. These studies manipulated predictability by setting the cue-target interval (foreperiod) to be fixed or random throughout the block. Findings showed that pre-target oculomotor behavior was reduced in the fixe...

description	Abstract Recent studies suggested that eye movements are linked to temporal predictability.
