Comparing the cerebral hemispheres on the speed of spatial shifts of visual attention: evidence from serial search.
We compared the speed at which visuo-spatial attention may be shifted from one stimulus to another as a function of the visual hemifield in which the items were displayed in a visual search task requiring serial processing. The increase in response time with the number of items displayed was similar for left- and right-hemifield presentations. This suggests that the rate at which visuo-spatial attention can be shifted from one stimulus to another during visual search does not differ between the cerebral hemispheres.
