They are used to prevent this example from being entered in the database as a publication.+How efficient is visual search in real scenes? In 
 +searches for targets among arrays of randomly placed 
 +distractors, efficiency is often indexed by the slope of the 
 +reaction time (RT) × Set Size function. However, it may be 
 +impossible to define set size for real scenes. As an 
 +approximation, we hand-labeled 100 indoor scenes and 
 +used the number of labeled regions as a surrogate for set 
 +size. In Experiment 1, observers searched for named objects 
 +(a chair, bowl, etc.). With set size defined as the number of 
 +labeled regions, search was very efficient (~5 ms/item). 
 +When we controlled for a possible guessing strategy in 
 +Experiment 2, slopes increased somewhat (~15 ms/item), 
 +but they were much shallower than search for a random 
 +object among other distinctive objects outside of a scene 
 +setting (Exp. 3: ~40 ms/item). In Experiments 4–6, 
 +observers searched repeatedly through the same scene for 
 +different objects. Increased familiarity with scenes had 
 +modest effects on RTs, while repetition of target items had 
 +large effects (>500 ms). We propose that visual search in 
 +scenes is efficient because scene-specific forms of attentional 
 +guidance can eliminate most regions from the “functional set 
 +size” of items that could possibly be the target.
