JMH's JND ratios for the split field versus uniform field conditions for LM increments presented against Gray and Gray−LM backgrounds. The x axis is isomerizations of the pedestal (same as lower right and middle right panels in Fig. 4). The y axis is the JND ratio for discrimination data collected on a uniform and split field. Open circles are JND ratios from the Gray adapting field and filled gray circles are ratios from the Gray−LM adapting field. Error bars are 95% confidence intervals determined by a bootstrap analysis.
