      Alvarez, George Angelo; Gill, Jonathan; Cavanagh, Patrick (Association for Research in Vision and Ophthalmology, 2012)
      Previous studies have shown independent attentional selection of targets in the left and right visual hemifields during attentional tracking (Alvarez & Cavanagh, 2005) but not during a visual search (Luck, Hillyard, Mangun, ...
