WIKIMEDIA, ANTONIO PICCINIWorrying about money can clearly preoccupy the mind. Researchers now show that hovering concerns over money might also dim one’s mental function. The results of two experiments published today (August 29) in Science support the idea that there might be a causal relationship between financial strife and poor decision-making. “Previous views of poverty have blamed poverty on personal failings, or an environment that is not conducive to success,” Jiaying Zhao, one of the study’s authors, said in a press release. “We’re arguing that the lack of financial resources itself can lead to impaired cognitive function.”
Zhao, who studies human behavior at the University of British Columbia, along with her colleagues conducted both field and lab experiments. In one experiment, Zhao’s team asked New Jersey mall shoppers with various incomes to think about how they might take care of car repairs. When the cost of the hypothetical repairs was low, the participants did equally well on a cognitive test. However, when the cost was high, the wealthier subjects outperformed those of lesser means. “These findings fit in with our story of how scarcity captures attention. It consumes your mental bandwidth,” Zhao added.
In a second experiment, the researchers gave Indian sugarcane farmers cognitive tests before and after the harvest, which corresponds to fluxes in income. The farmers are typically constrained financially ...
