สรุป	Successive pile sorting is an extension of the single-level pile sort in which informants first divide a set of items into a few broad piles and then repeatedly subdivide each pile into finer groupings (or, in the lumping variant, repeatedly merge piles into coarser ones). Recording the level at which any two items first become separated yields a graded similarity measure that captures the hierarchical structure of a cultural domain, not just a single flat partition.	The triad test is an elicitation technique for measuring perceived similarity among the items of a cultural domain. Informants are shown items three at a time and asked to pick the one that is most different (or, equivalently, which two are most alike). Across many triads and many informants, the pattern of which items are repeatedly kept together yields a fine-grained similarity matrix that is analyzed with multidimensional scaling and clustering.
