If you like the scent of coffee, there is a good chance for a better performance in badytical tasks, a new study found
According to researchers, smell a coffee scent – which did not no caffeine – has an effect similar to drinking coffee, suggesting a placebo effect of the coffee scent.
The findings also suggest that the smell of coffee alone can help people perform better on the badytical part of the Graduate Management Suitability Test. "It's not just that the smell of coffee helped people perform better in badytical tasks, which was already interesting," said co-author Adriana Madzharov of the Institute of Stevens technology in the United States.
"But they also thought that they would do better, and we demonstrated that this expectation was at least partly responsible for improving their performance," Madzharov adds.
For the study published in the Journal of Environmental Psychology, the research team administered a GMAT algebra test of 10 questions in a computer lab to about 100 undergraduate business students .
The participants were divided into two groups. One group took the test in the presence of a coffee-type ambient scent, while a control group took the same test – but in an unscented room.
The researchers found that the group in the room smelled much higher coffee on the test.
The team also designed a follow-up survey – conducted among over 200 new participants – questioning them about various fragrance beliefs and their perceived effects on human performance.
Participants believed that they would feel more alert and energetic in the presence of a coffee scent, as opposed to a flower scent or no smell; and that exposure to coffee scent would increase their performance on mental tasks.
The results suggest that performance expectations can be explained by the fact that the smell of coffee alone makes people more alert and energetic.
Previous studies have also suggested that coffee may reduce the risk of heart disease, diabetes and dementia. ] IANS
