摘要:Experimental studies of stimulus equivalence typically have two phases: the first teaches a set of baseline conditional discriminations, and the second tests for emergent relations. For instance, after a participant learned baseline conditional discriminations AB and BC, emergence of conditional relations BA and CB documents symmetry, emergence of relation AC documents transitivity, and emergence of relation CA documents combined symmetry and transitivity. Positive results on tests for these properties document the formation of equivalence classes (e.g., Fields, Verhave, & Fath, 1984; Sidman & Tailby, 1982). Studies often omit tests for reflexivity and, less frequently, take combined symmetry and transitivity as the sole evidence of equivalence.
