Movement aftereffect of bi-vectorial transparent motion.
Two moving random-pixel arrays (RPAs) were presented simultaneously in the same target field. These RPAs are perceived as two superimposed transparent moving sheets. Although two directions are perceived simultaneously during stimulus presentation, the movement aftereffect (MAE) is unidirectional. The visual system averages both motion signals in the MAE. For motion vectors of equal magnitude a...
متن کاملThe motion aftereffect of transparent motion: Two temporal channels account for perceived direction
Adaptation to orthogonal transparent patterns drifting at the same speed produces a unidirectional motion aftereffect (MAE) whose direction is opposite the average adaptation direction. If the patterns move at different speeds, MAE direction can be predicted by an inverse vector average, using the observer's motion sensitivity to each individual pattern as vector magnitudes. These weights are w...
متن کاملAdaptation state of the local-motion-pooling units determines the nature of the motion aftereffect to transparent motion
When observers adapt to a transparent-motion stimulus, the resulting motion aftereffect (MAE) is typically in the direction opposite to the vector average of the component directions. It has been proposed that the reason for this is that it is the adaptation state at the local-level (i.e. of the local-motion-pooling units) that determines the nature of the MAE (Vidnyanszky et al. Trends in Cogn...
متن کاملThe motion aftereffect.
The motion aftereffect is a powerful illusion of motion in the visual image caused by prior exposure to motion in the opposite direction. For example, when one looks at the rocks beside a waterfall they may appear to drift upwards after one has viewed the flowing water for a short period-perhaps 60 seconds. The illusion almost certainly originates in the visual cortex, and arises from selective...
متن کاملThe motion aftereffect reloaded.
The motion aftereffect is a robust illusion of visual motion resulting from exposure to a moving pattern. There is a widely accepted explanation of it in terms of changes in the response of cortical direction-selective neurons. Research has distinguished several variants of the effect. Converging recent evidence from different experimental techniques (psychophysics, single-unit recording, brain...
