Although early neurobiological and psychophysical evidence indicates some inhomogeneities of the human visual field such as different sensitivities measured by light-difference thresholds and different saccadic programming modes for perifoveal and peripheral stimuli, attention control in the visual field is traditionally believed to be homogenous. Using spatial cueing paradigms new evidence has been accumulated, pointing towards a functional subdivision of attention control in the visual field. Specifically, the periphery is significantly different from fovea and perifoveal regions of the visual field. An overview of behavioral studies measuring both exogenous and endogenous cueing effects as well as imaging studies measuring inhibition of return effects using ERP, fMRI and MEG technologies is provided to systematically examine these new observations. Different attention systems rather than one unitary system responsible for the attention control in different areas of the visual field are proposed.
