“…For this reason, the simultaneous occurrence of blinks and saccades is an efficient strategy for minimising visual suppression (Fogarty and Stern 1989). As reported in section 3.4.2, the zero-lag time-locking of saccades and blinks frequently observed in the literature (Zuber and Stark 1966;Rottach et al 1998) is not found here. It is, however, obtained in the first time interval, before the moment 1100 ms prior to the button-press, where we tentatively located the initiation of the switch, as well as after the switch response has been completed.…”

According to a widely cited finding by Ellis and Stark (1978 Perception7 575–581), the duration of eye fixations is longer at the instant of perceptual reversal of an ambiguous figure than before or after the reversal. However, long fixations are more likely to include samples of an independent random event than are short fixations. This sampling bias would produce the pattern of results also when no correlation exists between fixation duration and perceptual reversals. When an appropriate correction is applied to the measurement of fixation durations, the effect disappears. In fact, there are fewer actual button-presses during the long intervals than would be expected by chance. Moving-window analyses performed on eye-fixation data reveal that no unique eye event is associated with switching behaviour. However, several indicators, such as blink frequency, saccade frequency, and the direction of the saccade, are each differentially sensitive to perceptual and response-related aspects of the switching process. The time course of these indicators depicts switching behaviour as a process of cascaded stages.

“…Such masking by subsequent stimulation is potentially an ever-present concomitant~f eye movements in normally lit environments. Depression of visual sensitivity in the presaccadic interval (Volkmann, 1962;Latour, 1962;Zuber & Stark, 1966;Volkmann et al, 1968) might S1 Jplement such an effect. This suggests that some essential factor in the appearance of stability for stationary objects present during the presaccadic period resides in the continuous presence of such objects, and that our ability to measure shifts in the present type of experiment depends on our utilization of flashed stimulation.I I NOTES 1.…”

“…up to the beginning of the next fixation. Saccadic suppression affects perception of dim flashes [104][105][106] of image displacements [107] as well as the corresponding cortical evoked potentials [108][109][110]. It has also been shown to affect the perception of 'phosphenes' generated by central stimulation [111,112].…”

Corollary discharge: Its possible implications in visual and oculomotor interactions

Abstract--Data concerning the possible role of a corollary discharge mechanism in the regulation of visual-oculomotor interactions are reviewed. Several modes of action for such a mechanism on the processing of visual information are discussed. Mere suppression of visual input during saccades is considered mostly as a peripheral mechanism. It is proposed that corollary discharge could either produce an active cancellation of the effects of eye movements on vision, or contribute to the evaluation that a given visual change is provoked by a saccade. Cancellation could occur at subcortical levels of visual processing although evaluation could occur at the cortical level.
