Fig 1 — A. Histogram of 590 normosmic staircase-estimated thresholds (as determined by the mean of the last 4 reversals), together with a normal density curve with the same mean and standard deviation (solid black). In addition, the distribution of estimated thresholds from the fitted model is also plotted (dashed grey).B.
