When deciding between now and later, the tendency to devalue later outcomes is known as temporal discounting. The degree of devaluing is known as one’s discounting rate. Steeper temporal discounting rates indicate preferences for immediate gains and delayed losses, reflecting a desire for instant gratification and greater loss aversion, respectfully. Considering that decrements in decision-making abilities may precipitate cognitive dysfunction and decline, a better understanding of decision-making preferences among older adults represents an important endeavor. Thus, the current study aimed to investigate whether differences among temporal discounting rates for gains and losses exist when outcomes are monetary or interpersonal in nature.

One hundred and forty community-dwelling older adults aged 50 to 90 (75% female, Mage=71.6) completed a hypothetical discounting task in which they chose between smaller immediate outcomes and larger delayed outcomes presented at various delay periods of one week, one month, six months, and one year. An iterative algorithm determined the indifference point for each delay period. Indifference points were fit to hyperbolic models using nonlinear regressions to determine discounting rates within each condition. Nonparametric Wilcoxon Signed-Rank tests compared discounting rates.

Older adults more steeply discounted monetary gains as compared to monetary losses (Z=-6.88, p<.001), as well as for social gains compared to social losses (Z=-4.81, p<.001). They also discounted social gains more steeply than monetary gains (Z=-5.44, p<.001), and social losses more steeply than monetary losses (Z=-4.44, p<.001).

Preliminary findings suggest older adults displayed a greater desire for instant gratification of rewards, particularly social rewards, yet also displayed lower loss aversion, particularly for monetary losses. Stronger preferences for instant gratification of gains in certain contexts may inform ways in which healthier lifestyle choices or changes could be framed to appeal to older adults.
