The performances of three age groups (50-, 60-, and 70-year-olds) were
compared on an eye-voice span (EVS) task, and their performance was r
elated to eyesight, intelligence (fluid and crystallized), education l
evel, and quality and quantity of reading experience. There was a sign
ificant age-related quantitative decline in EVS, but no qualitative ch
ange. This decline could not be completely accounted for by any of the
other variables, lending credence to a theory of a general aging effe
ct. The finding that a decline in EVS was not reflected in a change in
reading speed indicates a possible compensatory mechanism implication
s of the findings are discussed.
