The Pattern of Utilization of Visual Information during Fixations in Reading. Technical Report No. 395.
Blanchard, Harry E.
A series of studies investigated the manner in which information is utilized during fixations in continuous reading. Utilization refers to visual information being processed to further the comprehension of the text being read, in contrast to registration, which refers to visual information simply being available to the brain. The studies considered three patterns of utilization during fixation: (1) utilization immediately follows registration, (2) utilization comes from different regions at different times, and (3) utilization occurs at a specific time that can vary. Three experiments were conducted using a paradigm developed by H. E. Blanchard, G. W. McConkie, D. Zola, and G. S. Wolverton. Subjects were college students or graduates recruited through a college newspaper, who read text displayed on a video terminal. Results of the first two experiments showed that the crucial findings from the Blanchard and others paradigm were due to memory or other nonperceptual processes, thus ruling out the possibility that utilization always occurs immediately after new visual information is registered. The third experiment eliminated the possibility that visual information is used letter by letter in a left-to-right scan. The results are consistent with the proposal that utilization occurs at a specific time that varies, sometimes early and sometimes late in the fixation.
