Study shows age doesn't necessarily affect decision-making
Date:6/29/2010

Many people believe that getting older means losing a mental edge, leading to poor decision-making. But a new study from North Carolina State University shows that when it comes to making intuitive decisions using your "gut instincts" older adults fare as well as their juniors.

The researchers tested groups of young adults (aged 17-28) and community-dwelling older adults (aged 60-86) meaning they live in the community, rather than in a nursing home to see how they fared when making decisions based on intuitive evaluation. For example, study participants were asked to choose from a list of apartments based on each apartment's overall positive attributes. Under such conditions, young and older adults were equally adept at making decisions.

"But not every decision can be made that way," says Dr. Thomas Hess, a professor of psychology at NC State and co-author of the study. "Some decisions require more active deliberation. For example, those decisions that require people to distinguish pieces of information that are important from those that are unimportant to the decision at hand." And when it comes to more complex decision-making, Hess says, older adults face more challenges than their younger counterparts.

In one portion of the study, participants were given a list of specific criteria to use in selecting an apartment. That list was then taken away, and each participant had to rely on his or her memory to incorporate the criteria into their decision-making.

However, there was considerable variation among the older adults who participated in the study some did very well at the complex decision-making. "Older adults with a higher education did a better job of remembering specific criteria and utilizing them when they made decisions," says lead author Tara Queen, a psychology Ph.D. student at NC State. "Ultimately, they made better choices."

"This tells us that the effects of age on decision-making are not universa
