Eye movements, the perceptual span, and reading speed.
The perceptual span or region of effective vision during eye fixations in reading was examined as a function of reading speed (fast readers were compared with slow readers), font characteristics (fixed width vs. proportional width), and intraword spacing (normal or reduced). The main findings were that fast readers (reading at about 330 wpm) had a larger perceptual span than did slow readers (r...
متن کاملEye movements and reading in macular disease: Further support for the shrinking perceptual span hypothesis
Reduced perceptual span is one factor which limits reading speed in patients with macular disease. This study measured the perceptual span and the number of saccades to locate a target in 18 patients with macular disease and seven control subjects on two occasions separated by up to 12 months. Perceptual span changed by up to two letters. Changes in perceptual span were significantly related to...

متن کاملThe Perceptual Span and the Eye–Hand Span in Sight Reading Music
The perceptual span and eye–hand span of pianists were examined while they played and read single-line melodies (with four beats per measure). The perceptual span was measured by the use of a moving-window technique with four window conditions: two beats, four beats, six beats, or no window. It was found that pianists need to see no more than the whole measure that they are fixating in order to...
متن کاملEye movements and reading speed in macular disease: the shrinking perceptual span hypothesis requires and is supported by a mediation analysis.
PURPOSE Reading speed of patients with central field loss (CFL) correlates with the size of saccades (measured in letters per forward saccade [L/FS]). We assessed whether this effect is mediated by the total number of fixations, by the average fixation duration, or by a mixture of both. METHODS We measured eye movements (with a video eye tracker) of 35 AMD and 4 Stargardt patients (better eye...
