Can subjects shift their attention to areas of the visual field peripheral to the fixation point without moving their eyes?
a) no, because focusing attention to areas of the visual field peripheral to the fixation point requires the subject to move the eyes to focus on them visually
b) no, because the brain activity diminishes as the attended sector moves out from the fovea
c) yes, because the areas of highest brain activity move toward the occipital pole as the attended sector moves out from the fovea
d) yes, as indicated by shifts in patterns of activity in the visual cortex when a subject is fixated on a central point, and the stimulus is presented at a distance from the fixation point
