Multidimensional space representations like those posited in Edelman's
target article are not sufficient to capture all similarity phenomena
. We discuss phenomena that are compatible with models of similarity t
hat assume structured relational representations. An adequate model of
similarity and perception will require multiple approaches to represe
ntation.
