22 college students were recruited in the experiment, 10 males and 12 females with normal vision or corrected vision and right handedness, whose ages range from 20 to 26 years old. Informed consent was obtained from each subject by explaining to them the detailed experimental procedures. All the subjects were paid after the experiment.
A Pentium Ⅳ personal computer equipped with 17 inch flat panel Dell monitor was used with a resolution of 1024×768 and a refresh rate of 85 Hz. All the tests were performed in a dark room with a black screen background, and the subjects stayed 57 cm away from the center of the screen.
