The properties within each theory, however, do not carry equal weight; some are more central to the characterization of the category than others. The most central of these we will call PREDOMINANT FEATURES. Thus predominant features of bricks seem to be their box shape and child's-shoebox size. [...] A predominant feature of a category is one that tends to hold for most of its members - especially its typical members - but not for members of neighboring categories.
