Use of descriptive and experiential information in decision making by young and older adults.

Age differences involving decision by description versus decision by experience were examined using the same general task structure to facilitate comparisons across decision types. Experiment 1 compared younger (19-43 years) and older (65-85 years) adults in four different experimental conditions involving a choice between a low-risk, low-return bet versus a high-risk, high-return bet. Experiment 2 compared young (18-27 years) to older (60-87 years) adults using similar experimental conditions, but with decisions involving a risky versus a certain option. Contrary to expectations, minimal differences were observed between ages in either study. Higher levels of ability and numeracy were associated with better performance and greater ability to benefit from experience, but the impact of these factors was not moderated by age. The results suggest that factors other than the simple distinction between decisions by description versus experience are necessary to characterize the nature of age effects in decision-making.
