Identifying the Span of the Effective Stimulus in Reading. Final Report.
McConkie, George W.; Rayner, Keith
A computer-based Eye-Movement Controlled Display System was developed for the study of perceptual processes in reading. Studies were conducted to identify the region from which skilled readers pick up various types of visual information during a fixation while reading. The results indicated that the subjects acquired word length pattern information at least 12 to 15 character positions to the right of the fixation point, and that this information primarily influenced saccade lengths. Specific letter and word shape information was acquired no further than 12 or 13 character positions to the right of the fixation point. It appeared that words were given a semantic interpretation only if they began no more than 5 or 6 character positions to the right of the fixation point. The perceptual span was found to be asymmetric, with the subjects acquiring information no further than 4 character positions to the left of the fixation point, and perhaps less. (Author/RB)
