“…Previous studies by Fu et al (2001) and Kanai et al (2006) demonstrated that the extrapolation of visual targets farther in the direction of motion was larger for spatially blurred targets-that is, for targets with a high degree of position uncertainty. Our results at paralateral spatial locations are in accord with these earlier findings and confirm that position uncertainty due to less precise encoding of spatial coordinates leads to larger forward displacements.…”

“…Previous studies in which position uncertainty was induced either by the blurring of target intensity and contrast (Fu, Shen, & Dan, 2001) or by peripheral stimulus presentation (Kanai, Sheth, & Shimojo, 2006) have shown that less accurate positional information results in larger forward displacements. On the basis of the latter findings, we hypothesized that less precise encoding of spatial coordinates in paralateral and lateral space leads to greater position uncertainty and should be reflected in an increase in the magnitude of forward displacement.…”

Similarities have been observed in the localization of the final position of moving visual and moving auditory stimuli: Perceived endpoints that are judged to be farther in the direction of motion in both modalities likely reflect extrapolation of the trajectory, mediated by predictive mechanisms at higher cognitive levels. However, actual comparisons of the magnitudes of displacement between visual tasks and auditory tasks using the same experimental setup are rare. As such, the purpose of the present free-field study was to investigate the influences of the spatial location of motion offset, stimulus velocity, and motion direction on the localization of the final positions of moving auditory stimuli (Experiment 1 and 2) and moving visual stimuli (Experiment 3). To assess whether auditory performance is affected by dynamically changing binaural cues that are used for the localization of moving auditory stimuli (interaural time differences for low-frequency sounds and interaural intensity differences for high-frequency sounds), two distinct noise bands were employed in Experiments 1 and 2. In all three experiments, less precise encoding of spatial coordinates in paralateral space resulted in larger forward displacements, but this effect was drowned out by the underestimation of target eccentricity in the extreme periphery. Furthermore, our results revealed clear differences between visual and auditory tasks. Displacements in the visual task were dependent on velocity and the spatial location of the final position, but an additional influence of motion direction was observed in the auditory tasks. Together, these findings indicate that the modalityspecific processing of motion parameters affects the extrapolation of the trajectory.

“…There is strong evidence that this occurs in perception (Ramachandran and Anstis 1990;De Valois and De Valois 1991;Snowden 1998;Nishida and Johnston 1999;Whitaker et al 1999;Hayes 2000;Whitney and Cavanagh 2000;Fu et al 2001;McGraw et al 2002;Mussap and Prins 2002;Edwards and Badcock 2003;Watanabe et al 2003;Whitney et al 2003a;Durant and Johnston 2004;Fu et al 2004;Shim and Cavanagh 2004; for a review, see Whitney 2002), and in visually-guided behavior (Mohrmann-Lendla and Fleischer 1991;Brenner and Smeets 1997;Yamagishi et al 2001;Ma-Wyatt and McGraw 2003;Whitney et al 2003b;Ashida 2004), though the influence of visual motion on perception and action may operate on different timescales (Whitney et al 2003b). This explanation is consistent with the finding that even during fixation, a moving background can influence reaching movements to a stationary object (Brenner and Smeets 1997;Yamagishi et al 2001;Whitney et al 2003b).…”

Movement of the body, head, or eyes with respect to the world creates one of the most common yet complex situations in which the visuomotor system must localize objects. In this situation, vestibular, proprioceptive, and extra-retinal information contribute to accurate visuomotor control. The utility of retinal motion information, on the other hand, is questionable, since a single pattern of retinal motion can be produced by any number of head or eye movements. Here we investigated whether retinal motion during a smooth pursuit eye movement contributes to visuomotor control. When subjects pursued a moving object with their eyes and reached to the remembered location of a separate stationary target, the presence of a moving background significantly altered the endpoints of their reaching movements. A background that moved with the pursuit, creating a retinally stationary image (no retinal slip), caused the endpoints of the reaching movements to deviate in the direction of pursuit, overshooting the target. A physically stationary background pattern, however, producing retinal image motion opposite to the direction of pursuit, caused reaching movements to become more accurate. The results indicate that background retinal motion is used by the visuomotor system in the control of visually guided action.

“…Either the flash-lag is an ensemble of different phenomena -and some, indeed, are unusual 92 -that have their own explanations, or there is one explanation common to visual change in general. One could go one step further and ask: do changes in modalities other than vision produce similar illusions?…”

Through the eye, slowly; Delays and localization errors in the visual system

Reviews on the visual system generally praise its amazing performance. Here we deal with its biggest weakness: sluggishness. Inherent delays lead to mislocalization when things move or, more generally, when things change. Errors in time translate into spatial errors when we pursue a moving object, when we try to localize a target that appears just before a gaze shift, or when we compare the position of a flashed target with the instantaneous position of a continuously moving one (or one that appears to be moving even though no change occurs in the retinal image). Studying such diverse errors might rekindle our thinking about how the brain copes with real-time changes in the world.
