Reliability of a measure of temporal discounting.
Participants (N = 17) chose between smaller, immediate and larger, delayed hypothetical money amounts in two laboratory sessions separated by 1 week. The choice procedure yielded equivalence points at which participants were indifferent between the smaller, immediate and the larger, delayed reward f...

Vuchinich, Rudy E. su: Choice (Psychology) Self-control Experimental design sug: subj: Choice (Psychology) Self-control Experimental design ab: Participants (N = 17) chose between smaller, immediate and larger, delayed hypothetical money amounts in two laboratory sessions separated by 1 week. The choice procedure yielded equivalence points at which participants were indifferent between the smaller, immediate and the larger, delayed reward for eight different delays of the larger reward. These equivalence points then were used to estimate temporal discounting parameters according to three different discounting functions. A hyperbolic discounting function accounted for more of the variance than an exponential function, which replicated earlier research. Correlations across sessions showed that the discounting parameters were reliable, and that the equivalence points were reliable for delays greater than 1 month.
