“…The speeding-up of perceptual, that is, sensory processing as an effect of attention was intensively investigated for more than a hundred years with various paradigms in different sensory modalities. However, evidence supporting the existence of the prior-entry effect, to date, is rather mixed (Di Russo and Spinelli, 1999;McDonald et al, 2005;Schneider and Bavelier, 2003;Schuller, and Rossion, 2001;Seibold et al, 2011;Shore et al, 2001;Spence et al, 2001;Vibell et al, 2007;Yates, and Nicholls, 2009;Zampini et al, 2005; for summary, see Spence, and Parise, 2010). Due to its superior temporal resolution, the method of event related brain potentials (ERPs) is a suitable choice for the investigation of changes in processing speed.…”
