Perceived shift of the centres of contracting and expanding optic flow fields: Different biases in the lower-right and upper-right visual quadrants

Abstract: We studied differences in localizing the centres of flow in radially expanding and contracting patterns in different regions of the visual field. Our results suggest that the perceived centre of a peripherally viewed expanding pattern is shifted towards the fovea relative to that of a contracting pattern, but only in the lower right and upper right visual quadrants and when a single speed gradient with appropriate overall speeds of the trajectories of the moving dots was used. The biases were not systematicall… Show more

“…It seems that the strong interconnectivity of the two hemispheres (Carlei & Kerzel, 2017) may compensate for all the possible asymmetries in CFF. Our results suggest that the differences in the perception of visual stimuli between left and right VFs observed in the literature are more likely task-related and manifest in specific higher-order information processing (e.g., attention reorienting, detection or competition) rather than the temporal sensitivity (Carlei & Kerzel, 2017;Cheng et al, 2019;Corbetta & Shulman, 2011;Powell, 1982;Wright et al, 2016). However, based on the trend of higher value of CFF (after-before training)−(after-before rest) and CFF (after break-before training)−(after break -before rest) parameters in left compared to right VH at 30° eccentricity, which we observed in our exploratory analysis, abnormal conditions (such as exercise) may act differently on these two VHs.…”

“…Vertical asymmetries between visual signal processing in healthy humans have been reported and the contribution of both spatial attention and structural organization of the visual system, including the anisotropies within the retina and the cortical retinotopic areas, has been discussed (Cheng et al., 2019; Curcio & Allen, 1990; Levine & McAnany, 2005; Rezec & Dobkins, 2004; Silva et al., 2014; Tyler, 1987; Zito et al., 2016). Lower VH has been shown to advantage for low‐level stimuli (contrast sensitivity, space and motion processing, light sensitivity in orientation, discrimination, detection, localization, and visual search tasks), whereas upper VH benefits for higher level visual processing, such as complex objects and shapes or face processing (Rezec & Dobkins, 2004; Silva et al., 2014; Zito et al., 2016).…”
