Abstract
The first eye movement from a point of fixation was detected by direct observation of the eye, by electro-oculograph (EOG), and by corneal reflection apparatus. Essential agreement was obtained among the measures. Only with movements less than 5° were there serious numbers of discrepancies in detection against the criterion of photo-recorder corneal reflection measurement. A horizontal movement was detected more reliably than a vertical movement. The EOG was most likely to miss detection of a vertical movement. The efficiency of the measures with regard to movement detection and monitoring choice-looking-behavior were discussed.Keywords
