“…On the one hand, some studies have argued that the oculomotor system pertains to some types of IOR; accordingly, a perceptual process is modulated when fixation is maintained, whereas a motoric process is modulated when eye movements are made to a cued location (Chica et al, 2010;Taylor & Klein, 2000). On the other hand, several studies have argued that the activation state of the reflexive oculomotor system controls which type of IOR is generated; accordingly, a perceptual form is generated when the system is suppressed, whereas a motoric form is generated when the system is not suppressed (Hilchey, Dohmen, Crowder, & Klein, 2016;Hilchey et al, 2014;Redden, Hilchey, & Klein, 2016; for a review, see . In either case, it has been suggested that a blocked design is not an optimal procedure to segregate these different types of IOR (Hilchey, Klein, & Ivanoff, 2012).…”
