Highlights
► We investigated differences in spatial-frequency requirements in central and peripheral vision for human pattern recognition. ► The minimum ranges of spatial frequencies for reliable letter and face recognition are larger in peripheral vision. ► The shape of the human contrast-sensitivity function and a source of internal noise can account for these differences.
