Adaptation in offer value responses with positive and negative encoding. A, Positive encoding. B, Negative encoding. Each panel illustrates the overlay of mean responses for high⇔low, high⇔wide, and low⇔wide transitions. High⇔wide and low⇔wide transitions are aligned to the wide range. High⇔low transitions are aligned to the total range across blocks (i.e., the lowest value in the low range and the highest value in the high range).
