Abstract

There were few data for spot of the difference searching skilled on eye movement. Especially, it was unknown how to view and recognition of spot difference quickly. The purpose of this study was to investigate the behavior of spot the difference due to the time pressure tasks. Twelve students participated in this study (average 21years old). Every subject equipped eye movement apparatus recorder (NAC EMR-9, Tokyo Japan), it was displayed gaze point of spot the difference as the stimulus pictures. The attention stimuli was same two photos it’s has spot the difference. The device was measured the spot of the difference as x and y coordinated. It was within one minute to each one recorded searching behavior. After recording gaze and eye movement coordinate apparatus was analyzed it with analytical software (EMR-dFactory ver2.12b, Tokyo Japan). The results of this study was the findings of major two skilled patterns. They gaze tracking one side that was not easily to find out the spot of difference like as inattentional blindness. And it was too quickly eye gaze movement to detected difference. The other it was equal time and trajectory on right and left stimulus picture.
