Developmental changes in letter recognition as affected by parafoveal noise.
The effect of parafoveal noise information on a Hirakana target-recognition task was investigated with 10 good and 10 poor readers in first and second grades (ns = 20 per grade). A differential effect of parafoveal noise produced a longer or shorter variation in RT depending on the kind of surrounding material. This suggests that the filtering mechanism whereby unnecessary information is avoided becomes more efficient from the first to the second grade of school attendance.
