A Comparison of Discounting Parameters Obtained Through Two Different Adjusting Procedures: Bisection and Up-Down.

The study compared delay discounting in adult humans using two different methods of adjustments. Both methods used hypothetical choices of monetary outcomes. One involved adjustments using a fixed sequence of ascending or descending amounts, the other used a bisection algorithm in which the changes in amounts varied as a function of the subjects' choices. Two magnitudes of delayed outcomes were used: $1,000 and $10,000. A within subject design was used to compare indifference curves and discounting measures across the two adjusting procedures. Twenty four subjects were divided in two groups and exposed to the procedures in opposite order, to account for sequence effects. Results from within subject comparisons showed no systematic differences between procedures.
