Description
The retinotopic organization of visual information is shifted with each saccade. Yet, we experience a continuous stream of visual information. The discrepancy between the disrupted retinotopic organization and apparent perceptual continuity of visual information has been studied for centuries. There is still an ongoing debate whether perceptual continuity across saccades is illusory, or whether retinotopic representations of visual information are updated across saccades. Recent studies provided a considerable amount of evidence in favour of spatiotopic updating of visual information, enabling perceptual continuity. Importantly, these studies showed that the build-up of spatiotopic coding takes up to 500 ms, plus saccade latency. Under normal viewing conditions, this would be too slow to support perceptual continuity, since saccades are made roughly every 300 ms. With a series of experiments involving a motion illusion (High Phi), we demonstrate that spatiotopic updating can occur within the latency of normal visually guided saccades, and that the effect of spatiotopic updating can be measured very rapidly after saccade offset. Together, our results provide a behavioural demonstration of rapid spatiotopic updating of visual information, that directly demonstrates perceptual continuity across saccades.| Period | 13 Mar 2018 |
