ABSTRACT
Notwithstanding the mass of evidence pointing to a core phonological deficit in dyslexia (Stanovich, 1988b), many findings suggestive of early or low-level visual processing anomalies have been reported in recent years. For example, it has been reported that young disabled readers, as well as adult dyslexics (Winters, Patterson, & Shontz, 1989), differ from age-matched controls in showing increased durations of visible persistence (Badcock & Lovegrove, 1981; Lovegrove et al., 1980b; Stanley & Hall, 1973; but see Hogben et al., 1995) and lower critical flicker-fusion thresholds (Lovegrove et al., 1986; Talcott, Hansen, Willis-Owen, McKinnell, Richardson, & Stein, 1998).
