Alvarez, George A, and Patrick Cavanagh. "Independent Resources for Attentional Tracking in the Left and Right Visual Hemifields." Psychological Science 16, no. 8 (2005): 637-43.Abstract
The ability to divide attention enables people to keep track of up to four independently moving objects. We now show that this tracking capacity is independently constrained in the left and right visual fields as if separate tracking systems were engaged, one in each field. Specifically, twice as many targets can be successfully tracked when they are divided between the left and right hemifields as when they are all presented within the same hemifield. This finding places broad constraints on the anatomy and mechanisms of attentive tracking, ruling out a single attentional focus, even one that moves quickly from target to target.Citable link to this page
