Motion Adaptation Distorts Perceived Visual Position
After an observer adapts to a moving stimulus, texture within a stationary stimulus is perceived to drift in the opposite direction-the traditional motion aftereffect (MAE). It has recently been shown that the perceived position of objects can be markedly influenced by motion adaptation. In the present study, we examine the selectivity of positional shifts resulting from motion adaptation to st...
متن کاملMotion distorts perceived position without awareness of motion
A number of striking illusions show that visual motion influences perceived position [1]; in all of these, the perceived shift is accompanied or preceded by a visible and salient motion signal. Observers can easily scrutinize the motion: they can attentively track, or at least perceive via inference, the moving features [2–4]. With position shifts that accompany the motion aftereffect (MAE) [5–...
متن کاملMotion distorts perceived depth
Two important tasks that the visual system has to perform are determining the direction of motion and the spatial location of objects. It has recently been shown that the perceived location of an object moving in the frontal-plane is displaced along the direction of motion (e.g. Nature 397 (1999) 610; Vision Research 31 (1991) 1619). The aim of the present study is to examine the extent of this...
متن کاملShifts in perceived position following adaptation to visual motion
Where do we perceive an object to be when it is moving? Nijhawan [1] has reported that if a stationary test pattern is briefly flashed in spatial alignment with a moving one, the moving element actually appears displaced in the direction in which it is moving. Nijhawan postulates that this may be the result of a mechanism that predicts the future position of the moving element so as to compensa...
متن کاملVisual motion distorts visual and motor space.
Much evidence suggests that visual motion can cause severe distortions in the perception of spatial position. In this study, we show that visual motion also distorts saccadic eye movements. Landing positions of saccades performed to objects presented in the vicinity of visual motion were biased in the direction of motion. The targeting errors for both saccades and perceptual reports were maximu...
