Examples of complex searches involving complex shapes used in previous studies and their associated simple searches. The LNS search T among N and J (A) is harder than the LS search for T among N and L (E). The related simple searches show one common search (T among N, panels B and F). For the other two searches, the LNS target is more similar to the distracter (TJ is harder than TL, panels C vs. G), and the LNS distracters are more heterogeneous (NJ is easier than NL, panels D vs. H). These two effects cause the LNS search to be harder than the LS search.
