Description: Buetti, Cronin, Madison, Wang, & Lleras (in press) recently reported that, contrary to previous theories, the first stage of processing in visual search varies systematically with the number of items in the display and that this variation is modulated by target-distractor similarity. In this study, we aim to investigate whether the order in which candidates are scrutinized during stage-two processing is ranked-order by target-distractor similarity (as most theories assume) or whether the order is in fact random (see Buetti et al., in press). That is to say, do observers scrutinize candidates according to their visual similarity to the target, inspecting the most similar candidates first and the least similar candidates last?
