Sensitivity loss in odd-symmetric mechanisms and phase anomalies in peripheral vision

Abstract The ability to detect, discriminate and identify spatial stimuli is much poorer in the peripheral than in the central visual field. Some deficits are eliminated by scaling stimulus size. For example, grating detectibility is roughly constant across the visual field when spatial frequency and target extent are scaled appropriately1,2. Other deficits persist despite scaling. For instance, some readily detectable patterns are more …
