THE ACCURACY OF JUDGMENTS OF EYE FIXATIONS

POPERCEPTION, Perception, Vision, Tests. An attempt was made to provide descriptive data on the judgment of eye fixations from photographs, a method similar to that devised by Baker Science 132674-675, 1960. It appears that the main danger in using this technique for studying the observing behavior of subjects is the inaccuracy with which downward fixations are judged. As a generalization, one may say that foveal vision with reference to the center point may be misjudged as peripheral vision and peripheral vision may be misjudged as foveal vision in the order of five to ten percent of the time. It is also possible that a camera with better resolution than the one used in this study would produce better performance by the judges. It is further possible that judgments could be improved by the use of motion pictures, rather than still photographs. Author
