Figure 4

Individual estimates of k for the adjusting-amount procedure plotted against the individual estimates for the corresponding adjusting-delay procedure from both Experiment 1 (filled circles) and Experiment 2 (open circles) of Green et al. (2007). The dashed line represents equivalent rates of discounting. Figure is from “Do adjusting-amount and adjusting-delay procedures produce equivalent estimates of subjective value in pigeons?” by L. Green, J. Myerson, A. K. Shah, S. J. Estle, and D. D. Holt, 2007, Journal of the Experimental Analysis of Behavior, 87, p. 345. Copyright 2007 by John Wiley & Sons, Inc.
