Preliminary Acceptability and Efficacy of an Expected Value Decision-Making Training Intervention among Older and Younger Adults: A Pilot Study
This pilot study demonstrates that a two-week Expected Value maximization training intervention is feasible, highly acceptable, and preliminarily effective at improving risky decision-making in older adults, whereas it showed no benefit and higher attrition among younger adults.

Imagine your brain is a super-smart navigation app. Usually, it's great at finding the fastest route. But as we get older, sometimes the app gets a little glitchy when it has to choose between a "sure thing" and a "risky gamble" with money or health. It might pick the risky path just because the prize looks shiny, or play it too safe because the risk looks scary, even when the math says otherwise.
A team of researchers from Clemson University wanted to see if they could give older adults a "software update" to fix this glitch. They created a special training called Expected Value (EV) Maximization. Think of this not as a magic pill, but as a new set of instructions for the brain: "Don't just look at the prize or the risk; multiply the prize by the chance of winning it, and pick the one with the highest number."
The Experiment: A Two-Week Road Trip
The researchers invited two groups of people to take a test drive:
- The Young Drivers: 35 college students (ages 18–21).
- The Experienced Drivers: 30 older adults (ages 60–85).
Everyone started with a baseline test where they had to choose between two doors. Behind one door was a guaranteed small reward, and behind the other was a risky chance at a big reward (or a loss). They had to pick the door that made the most mathematical sense.
The Results Before Training:
The "Experienced Drivers" (older adults) were struggling. They only picked the mathematically correct door 45% of the time. The "Young Drivers" were doing better, hitting 65% accuracy.
The Training:
Next, everyone watched a video explaining the "multiply the chance by the reward" rule. Then, they played a hands-on game with 200 rounds. Every time they made a choice, the game gave them instant feedback: "Correct!" or "Oops, here's why that door was better." It was like having a co-pilot shouting out the right math moves in real-time.
The Results After Training:
This is where the story gets interesting.
- The Older Adults: They got a massive boost! Their accuracy jumped from 45% to 84% right after training. Even two weeks later, they were still crushing it at 75%. The training stuck.
- The Young Adults: They didn't get any better. In fact, their performance dipped a bit two weeks later, dropping to 54%. The training didn't seem to help them at all.
Why the Difference?
The researchers found that the older adults loved the training. 93% said they were satisfied with it, and 97% found it interesting. They felt challenged and enjoyed learning a new strategy.
The younger adults, however, were a bit more critical. While 71% were satisfied, many complained about the length of the training and the user interface. It seems the older adults were hungry for a clear, useful tool to help them make better choices, while the younger adults were looking for a faster, flashier app experience.
What the Paper Rules Out (And What It Doesn't)
It's important to know what this study didn't prove.
- It didn't prove the training works for everyone: The study explicitly found that it did not help the younger adults. If you are young, this specific training might not change how you make risky choices.
- It didn't prove it works for real-life money: The study used a game with fake money (ranging from $0 to $25). The authors suggest the training might help with real medical or financial decisions, but they did not test that yet. We don't know if this "software update" works for choosing stocks or medical treatments.
- It didn't prove the skill transfers to other games: The training used a specific "door" game. The authors admit they aren't sure if the brain learned a general rule or just memorized how to play that specific door game.
The Bottom Line
This pilot study suggests that a simple, math-based training can act like a "cognitive tune-up" for older adults, helping them make much smarter risky choices almost immediately. The older adults found it useful and engaging, and their performance improved significantly.
However, this is just a first step. The researchers call it a "pilot study," meaning it's a small test to see if the idea works. While the results are promising for older adults, the study doesn't claim this is a solved problem or a guaranteed fix for everyone. It simply shows that with the right kind of practice and feedback, older adults can relearn how to weigh risks and rewards effectively.
