Eye Movement Monitoring in the Study of Silent Reading.
McConkie, George W.
Eye movement monitoring is useful both in the control of experiments on reading and as a source of data. Experiments using eye monitoring techniques have helped develop the following conclusions about the reading process: the region of text read during a fixation is quite small and asymmetric to the right of the center of vision, successive fixations are essentially nonoverlapping, the durations of fixations reflect cognitive processing occurring at that point in the text, and the eye is directed to specific locations in the text during reading. To continue exploring the reading process with eye movement techniques, a monitoring system was developed and tested using a Biometrics eye movement monitor connected to a PDP-11/40 computer. As the eye monitor reported eye positions 1,000 times per second, the computer controlled text display on a cathode ray tube (CRT) and recorded all data for analysis. Printouts of the data showed how eyes moved across a line of text, eye fixations and their lengths, movements between fixations, and changes in text display. Since the computer can be programed to make adjustments in the text display while eye movements are in progress, it provides greater control over experimental data and a faster means of verifying and refining previous research.
