The search surface. Slope of the search function indicates the slope of reaction time over an increasing set size. It is plotted as a function of target–distractor similarity (TDS) and distractor–distractor similarity (DDS). Due to the grouping of similar items, high search efficiency arises in conditions with low TDS (points a and c). Here, the target visually “pops out.” Low search efficiency arises on the opposite corners of the cube. It is especially pronounced when DDS is low (point d).
