Second-order motion shifts perceived position
Many studies have documented that first-order motion influences perceived position. Here, we show that second-order (contrast defined) motion influences the perceived positions of stationary objects as well. We used a Gabor pattern as our second-order stimulus, which consisted of a drifting sinusoidal contrast modulation of a dynamic random-dot background; this second-order carrier was envelope...
متن کاملMotion 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 کاملThe influence of visual motion on perceived position.
The ability of the visual system to localize objects is one of its most important functions and yet remains one of the least understood, especially when either the object or the surrounding scene is in motion. The specific process that assigns positions under these circumstances is unknown, but two major classes of mechanism have emerged: spatial mechanisms that directly influence the coded loc...
متن کاملThe motion-induced position shift depends on the perceived direction of bistable quartet motion
Motion can influence the perceived position of nearby stationary objects (Nature Neuroscience 3 (2000) 954). To investigate the influence of high-level motion processes on the position shift while controlling for low-level motion signals, we measured the position shift as a function of the motion seen in a bistable quartet. In this stimulus, motion can be seen along either one or the other of t...
