Physiological inequalites do not result in psychological inequalities in vision field: Evidence from a test of visual selective attention

It is well known that there are some characteristics of physiological inequality among vision fields. But, based on many studies, this inequality does not lead to psychological inequalities. Our aim was to assess directly the effect of vision field (foveal, parafoveal, peripheral) on irrelevant distractors’ rejection of selective attention and to determine whether or not the physiological inequalities of different vision fields bring out psychological inequalities. Results showed that there were significant differences in reaction time and error rate among 3 vision fields, but no distractor effect. Results demonstrated that perception processing efficiency was not balanced among the 3 types of vision, but does have a similar function of distractor rejection.
