Strikingly rapid neural basis of motion-induced position shifts revealed by high temporal-resolution EEG pattern classification

Abstract

Several visual illusions demonstrate that the neural processing of visual position can be affected by visual motion. Well-known examples are the flash-lag, flash-drag, and flash-jump effect. However, where and when in the visual processing hierarchy such interactions take place is unclear. Here, we used a variant of the flash-grab illusion (. Vision Research 91 (2013), pp. 8-20) to shift the perceived positions of flashed stimuli, and applied multivariate pattern classification to individual 64-channel EEG trials to dissociate neural signals corresponding to veridical versus perceived position with high temporal resolution. We show illusory effects of motion on perceived position in three se..
