Texture segmentation as a function of eccentricity, spatial frequency and target size.

摘要: Two experiments examined the role of fundamental spatial frequency, target area and retinal eccentricity in texture segmentation. In Experiment 1, a backward-masked comprising lines oriented orthogonally to surround was briefly presented at fovea, eccentricities ranging from 2.55 7.63 deg. Reaction time accuracy were better when targets non-foveal locations. 2, effects both frequency varied. Accuracy highest RT fastest near-peripheral, not foveal The corresponding optimal performance related inversely frequency. Results suggest that near periphery is more adept than fovea early processing which underlies rapid
