Abstract

"The existing literature has defined delay discounting as decrease in the value of a commodity as the delay to that commodity increases (Ainslie, 1975; Mazur, 1987). Some research has evaluated differences between hypothetical and real rewards with human participants (Johnson & Bickel, 2002; Lagorio & Madden, 2005); however, all studies to date provide some verbal or visual descriptions of the choice contingencies to human participants. The purpose of this study was to evaluate the behavioral processes in delay discounting assays through the examination of the effects of experimenter-delivered questions alone, contingencies alone, and both in conjunction. The results across both experiments in this study indicate that there were differences in the levels of discounting across conditions that do or do not include contingency descriptions."
