and use it in choice despite cognitive declines. Evidence in favor of such an explanation comes from studies examining performance using tasks such as the Iowa Gambling Task (IGT) and other similar tasks (Damasio, 1994), where age differences are often observed to be absent (e.g., MacPherson, Phillips, & Sala, 2002; Kovalchik, Camerer, Grether, Plott, & Allman, 2005; however in Denberg, Tranel, & Bechara, 2005, a subset of older adults performed significantly worse). In this task, subjects choose among decks of cards about which they initially know nothing. The decks vary in the amounts and frequencies of gains and losses and in overall

Individual differences in the neural signature of subjective value among older adults.
Some healthy older adults show departures from standard decision-making patterns exhibited by younger adults. We asked if such departures are uniform or if heterogeneous aging processes can designate which older adults show differing decision patterns. Thirty-three healthy older adults with varying decision-making patterns on a complex decision task (the Iowa Gambling Task) completed an interte...
متن کاملAdult Age Differences in Dual Information Processes: Implications for the Role of Affective and Deliberative Processes in Older Adults' Decision Making.
Age differences in affective/experiential and deliberative processes have important theoretical implications for judgment and decision theory and important pragmatic implications for older-adult decision making. Age-related declines in the efficiency of deliberative processes predict poorer-quality decisions as we age. However, age-related adaptive processes, including motivated selectivity in ...
متن کاملAge differences in dual information-processing modes: implications for cancer decision making.
Age differences in affective/experiential and deliberative processes have important theoretical implications for cancer decision making, as cancer is often a disease of older adulthood. The authors examined evidence for adult age differences in affective and deliberative information processes, reviewed the sparse evidence about age differences in decision making, and introduced how dual process...

متن کاملRisky choice in younger versus older adults: Affective context matters
Earlier frameworks have indicated that older adults tend to experience decline in their deliberative decisional capacity, while their affective abilities tend to remain intact (Peters, Hess, Västfjäll, & Auman, 2007). The present study applied this framework to the study of risky decision-making across the lifespan. Two versions of the Columbia Card Task (CCT) were used to trigger either affect...
متن کاملThe dark side of intuition: aging and increases in nonoptimal intuitive decisions.
When making decisions, people typically draw on two general modes of thought: intuition and reason. Age-related changes in cognition and emotion may impact these decision processes: Although older individuals experience declines in deliberative processes, they experience stability or improvement in their emotional processes. Recent research has shown that when older adults rely more on their in...
