To arrive at a quantitative description of these differences, we chose to compare the slope of the decreasing trend in the proportion of individuals choosing the extensive-options scenario across the maximizer and satisficer groups using a one-phase exponential decay model applied to the data and following the procedures outlined in Motulsky and Christopoulos, 2004.
