Visual search experiments in static displays have long established that size, color, andorientation are elementary features whose attributes are processed in parallel andavailable to guide the deployment of attention. Using a gaze-tracked flicker paradigm forchange blindness and stimuli rendered identically in space and separately in the 3feature dimensions, we investigate whether and how these features distinguishthemselves in the active deployment of attention during prolonged visual search. Wefind out that visual search does not show any attentional modulation in orientation,whereas it engages spatial attention in color with shorter saccades between the samecolor, and it engages featural attention in size with shorter fixation from previewing thesame size as well as tuning into a particular size. Thus, in terms of dynamic attributeprocessing over time, size, color, and orientation are highly distinctive: Betweensuccessive fixations, only orientation is truly pre-attentive without any form of priming,whereas size and color deploy attention in the featural and spatial domains respectively.
