  • Title: Eye movements and the perceptual span in older and younger readers.
    Author: Rayner K, Castelhano MS, Yang J.
    Journal: Psychol Aging; 2009 Sep; 24(3):755-60. PubMed ID: 19739933.
    Abstract:
    The size of the perceptual span (or the span of effective vision) in older readers was examined with the moving window paradigm (G. W. McConkie & K. Rayner, 1975). Two experiments demonstrated that older readers have a smaller and more symmetric span than that of younger readers. These 2 characteristics (smaller and more symmetric span) of older readers may be a consequence of their less efficient processing of nonfoveal information, which results in a riskier reading strategy.
