Completion takes measurable time

The finding that completion takes measurable time previously has been demonstrated using perceptual classification techniques (Ringach & Shapley, 1996; Shore & Enns, 1997), priming methods (Guttman et al., 2003; Sekuler & Palmer, 1992), and visual search (Gegenfurtner et al., 1997; Rauschenberger & Yantis, 2001).
