(Ivanhoe Newswire) -- Stressed out, man? Don't go to Vegas – send your wife instead.
New research shows men under stress may be more likely to engage in risky behavior such as gambling, smoking, unsafe sex and illegal drug use. In contrast, stressed women moderate their behavior and may be less likely to make risky choices, the study found.
"Evolutionarily speaking, it's perhaps more beneficial for men to be aggressive in stressful, high-arousal situations when risk and reward are involved," Nichole Lighthall of the University of Southern California Davis School of Gerontology and lead author of the paper is quoted as saying. "Applied to financial risk taking, it's akin to competition for territory or other valuable resources."
The researchers asked participants to play a game called the Balloon Analogue Risk Task in which inflating a balloon earns money (five cents per pump). Participants were told that they could cash out their earnings by clicking a "Collect $$$" button at any point in the game. However, the balloon would explode if it was inflated beyond its randomly determined breakpoint. If the balloon exploded, all winnings would be lost.
"One valuable aspect of the [balloon task] is its predictive validity for real-world impulsivity," Lighthall explained. "Some risk taking was necessary to make gains, but excessive risk was associated with diminishing returns. If you always clicked and never cashed out, you would lose every time."
In the control group, men and women displayed statistically similar levels of risk taking, inflating the balloon about 40 times on average. However, women in the stressed group only inflated the balloon an average of 32 times – more than 30 percent less often than their stressed male counterparts, who inflated the balloon an average of 48 times.
"Men seem to enter more risky financial situations than women, which was part of the impetus for our study," Lighthall said. "But only in the stressed condition did we see any statistical differences in risky behavior between men and women."
