Enhanced visual search performance when distracters are positioned according to real-world regularities. (A) The visual search paradigm consisted of a word cue that corresponded to a single target object. Participants indicated whether the target was on the right or on the left side of a briefly presented cluttered visual display. (B) Search arrays were the same displays as in the fMRI experiment, but houses were replaced by the search target on one side and a single distracter on the other side. Again, all distracter pairs could be presented in a regular or irregular configuration. (C) Regular distracter pairs led to higher accuracy than irregular pairs.
