Uncommitted Commitment: Behavioral Strategy to Prevent Preference Reversals.

Richard Yi, Hannah Milhorn, Anahi Collado, Kayla N Tormohlen, Jama Bettis,

When both smaller-sooner (SS) and larger-later (LL) rewards are temporally distal, individuals frequently prefer the LL. However, because both outcomes become proximal, individuals frequently switch to preferring the SS. These preference reversals are predicted by hyperbolic delay discounting, and may model the essential challenge of self-control. Using smokers, a population ... Read more >>

An alternative approach to calculating Area-Under-the-Curve (AUC) in delay discounting research.

Allison M Borges, Jinyi Kuang, Hannah Milhorn, Richard Yi,

Applied to delay discounting data, Area-Under-the-Curve (AUC) provides an atheoretical index of the rate of delay discounting. The conventional method of calculating AUC, by summing the areas of the trapezoids formed by successive delay-indifference point pairings, does not account for the fact that most delay discounting tasks scale delay pseudoexponentially, ...

Impact of episodic thinking on altruism.

Richard Yi, Alison Pickover, Allison M Stuppy-Sullivan, Sydney Baker, Reid D Landes,

Episodic future thinking, which refers to the use of prospective imagery to concretely imagine oneself in future scenarios, has been shown to reduce delay discounting (enhance self-control). A parallel approach, in which prospective imagery is used to concretely imagine other's scenarios, may similarly reduce social discounting (i.e., enhance altruism). In ... Read more >>

Exchanging the liquidity hypothesis: Delay discounting of money and self-relevant non-money rewards.

Allison M Stuppy-Sullivan, Kayla N Tormohlen, Richard Yi,

Evidence that primary rewards (e.g., food and drugs of abuse) are discounted more than money is frequently attributed to money's high degree of liquidity, or exchangeability for many commodities. The present study provides some evidence against this liquidity hypothesis by contrasting delay discounting of monetary rewards (liquid) and non-monetary commodities ... Read more >>
