“…Matin andPearce (1965, page 1487) themselves suggested that "compensation" might occur "at different rates at different regions of the visual field." Subsequent findings of Matin and his associates led them to conclude that the ERPS does not coincide with its saccade but is more sluggish (Matin et al, 1969(Matin et al, , 1970. Similar conclusions have been drawn by Schlag and associates (Dassonville et al, 1992;Schlag and Schlag-Rey, 1995;Cai et al, 1997) and by Honda (1989Honda ( , 1991Honda ( , 1993, who found substantial errors of location for targets flashed before the eye had moved, suggesting that the ERPS anticipated its saccade.…”

It is now well established that briefly flashed single targets are mislocalized in space, not only during saccades but also before them. We show here by several techniques (including a vernier judgment that did not require absolute location in space) that errors appear up to 100 msec before saccades are made and are maximal just before they start. The size and even the sign of errors depend strongly on position in the visual field, the complete pattern of errors suggesting a compression of visual space around the initial fixation point and the target of the impending saccade. The compression was confirmed by displaying multiple rather than single targets and was found to be powerful enough to reduce or even to remove vernier offset for pairs of bars shown simultaneously and to create offsets for colinear bars separated in time by 75 msec. It also reduced the apparent number of parallel bars. When saccades were simulated by moving the display at saccadic speed, there were sometimes errors of location, but only for tasks requiring absolute judgment of position. The pattern of errors differed greatly from that during saccades and, in particular, showed no signs of compression. We can model our saccade results by assuming a shift in the point in space associated with eye position compression of eccentricity along the axis of saccades.

“…This has been known at least since the time of Helmholtz [1], who suggested that an effort-ofwill is associated with the initiation of the eye movement and used by the visual system to predict the spatial location of a retinal flash when the eye is in motion. However, Matin et al [2] observed that such mislocalization occurred even when the flash was presented before the eyes began to move. This effect was found when the subject was in complete darkness and relied only on the retinal signal of the flash and any available information about the eye position or eye movement.…”

Perceptual phenomena that occur around the time of a saccade, such as peri-saccadic mislocalization or saccadic suppression of displacement, have often been linked to mechanisms of spatial stability. These phenomena are usually regarded as errors in processes of trans-saccadic spatial transformations and they provide important tools to study these processes. However, a true understanding of the underlying brain processes that participate in the preparation for a saccade and in the transfer of information across it requires a closer, more quantitative approach that links different perceptual phenomena with each other and with the functional requirements of ensuring spatial stability. We review a number of computational models of peri-saccadic spatial perception that provide steps in that direction. Although most models are concerned with only specific phenomena, some generalization and interconnection between them can be obtained from a comparison. Our analysis shows how different perceptual effects can coherently be brought together and linked back to neuronal mechanisms on the way to explaining vision across saccades.

“…Matin et al asked their subjects to report the visual direction of a brief flash presented in the dark at various times before, during, or following a voluntary saccade (Matin, Matin & Pearce, 1969;Matin, Matin & Pola, 1970). The direction of the flash was judged relative to the location of a fixation target viewed and extinguished before the saccade.…”

Subjects were required to perceptually judge the location of flash targets presented at the time of a saccade at various positions scattered two-dimensionally on a dimly illuminated structured background. The saccade-contingent n&localization was shown only in the direction parallel to the saccade, and not in the direction perpendicular to the saccade. In addition, the mislocalization uuder the "illuminated background" condition was different in several respects from that observed when targets were presented in the dark. It was suggested that the mislocalization is successfully explained by assuming three physiological and cognitive processes: a sluggish activity of the extraretinal eye position signal, visual cues from the visible background, and selective inattention to image displacements.
