Note. Set value refers to the average of Phase 1 ratings for the items in a choice set, while set salience refers to the (unsigned) difference between a given set value and a central reference point determined either by the participant-specific grand mean item value (Studies 1, 2, and 4) or the fixed midpoint on a bipolar rating scale (Study 3).
