Sentence-Frame Substitution Task

Free listing tells you which items belong to a domain and how salient they are, and pile sorting tells you how similar items are overall. Frame substitution instead recovers the specific attributes that define and separate items, by testing each item against feature-probing sentences. It typically follows free listing — which supplies the items — and complements pile sorting by explaining the features behind the groupings.

Good frames are derived from informants themselves: from the contrastive questions and statements that surface in open-ended interviews and from the structure of earlier free lists. The aim is to capture the dimensions the culture actually uses, not the researcher's a priori categories, so frame development usually involves an iterative, ethnographic phase before the systematic grid is administered.

Componential analysis seeks the minimal set of distinctive features that uniquely characterizes every item in a domain — the smallest combination of attributes that tells each item apart from the others. The item-by-attribute binary matrix produced by frame substitution is exactly its input: rows are items, columns are features, and the analysis searches for the parsimonious feature definitions implicit in the grid.
