In order to investigate the relationship between the visual global-local processing and the function of foveal and para-foveal visual field, the effects of the central and peripheral visual fields restriction on the performance on the Navon task and emotional face recognition task were investigated. Reaction time, correct answer rate and eye movement during the task were measured and evaluated. Under the condition with the peripheral visual fields restriction, reaction time was longer than other conditions, and the eye movement was globally distributed on the stimulus figures in both tasks. The correct answer rate was low in the Navon task but not in the emotional face recognition task. In contrast, under the central visual field restriction and without restriction, reaction time was not significantly different and the subjects gazed at the center of the stimulus figures, especially at the eye or between eyes in emotional face recognition task. Results indicated that the effect of the peripheral visual fields restriction on the visual processing was higher than those of the central restriction. |
