If you love the fragrance of coffee, there are high chances of better performance in analytical tasks, a new study has found.
According to the researchers, smelling a coffee-like scent — which has no caffeine in it — has an effect similar to that of drinking coffee, suggesting a placebo effect of coffee scent.
The findings also suggested that the scent of coffee alone may help people perform better on the analytical portion of the Graduate Management Aptitude Test (GMAT) — a computer adaptive test required by many business schools.
“It’s not just that the coffee-like scent helped people perform better on analytical tasks, which was already interesting,” said co-author Adriana Madzharov from the Stevens Institute of Technology in the US.
“But they also thought they would do better, and we demonstrated that this expectation was at least partly responsible for their improved performance,” Madzharov added.
For the study, published in the Journal of Environmental Psychology, the research team administered a 10-question GMAT algebra test 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 an ambient coffee-like scent, while a control group took the same test — but in an unscented room.
The researchers found that the group in the coffee-smelling room scored significantly higher on the test.
The team also designed a follow-up survey — conducted among more than 200 new participants — quizzing them on beliefs about various scents and their perceived effects on human performance.
The participants believed they would feel more alert and energetic in the presence of a coffee scent, versus a flower scent or no scent; and that exposure to coffee scent would increase their performance on mental tasks.
The results suggest that expectations about performance can be explained by beliefs that coffee scent alone makes people more alert and energetic.
Previous studies have also suggested that coffee may lessen the risk of heart disease, diabetes and dementia. (IANS)

Prior to the world going into lockdown, the after-hour culture in India bloomed at celebrated community hubs, that eventually became a safe-haven for individuals, a place where they found their sense of self-expression and belonging, that fuelled progress. This community was driven through the culture of live music and enthralling performances that created their very own vibe, a vibe that built extraordinary, forever-lasting relationships. Through #ReVibeTheNight, one can reconnect with this community bringing music curated by artists who have a history of captivating crowds with their one-of-a-kind live experiences. Catch the gigs and live performances for artists in these venues/cities for the live performances.

In a continuing study on the effects of machine learning (ML) on public conversation, Twitter has confirmed that its algorithms amplify right-leaning political content. "In six out of seven countries - all but Germany - tweets posted by accounts from the political right receive more algorithmic amplification than the political left when studied as a group," Twitter blogged.
"Right-leaning news outlets, as defined by the independent organisations, see greater algorithmic amplification on Twitter compared to left-leaning news outlets." Since 2016, Twitter users are able to choose between viewing algorithmically ordered tweets first in their home timeline or viewing the most recent tweets in reverse chronological order.
"An algorithmic home timeline displays a stream of tweets from accounts we have chosen to follow on Twitter, as well as recommendations of other content Twitter thinks we might be interested in based on accounts we interact with frequently, tweets we engage with, and more. "As a result, what we see on our timeline is a function of how we interact with Twitter's algorithmic system, as well as how the system is designed."
The new research is based on tweets of elected officials of House of Commons members in Canada, the French National Assembly, the German Bundestag, House of Representatives in Japan, Congress of Deputies of Spain, House of Commons in the UK, and official and personal accounts of House of Representatives and Senate members in the US, as well as news outlets, from April 1 to August 15, 2020.

The study was conducted by Ferenc Huszar (Twitter, University of Cambridge), Sofia Ira Ktena (now at DeepMind Technologies), Conor O'Brien (Twitter), Luca Belli (Twitter), Andrew Schlaikjer (Twitter), and Moritz Hardt (UC Berkeley).
The questions probed were:
How much algorithmic amplification does political content from elected officials receive in Twitter's algorithmically ranked Home timeline versus in the reverse chronological timeline? Does this amplification vary across political parties or within a political party?
Are some types of political groups algorithmically amplified more than others? Are these trends consistent across countries?
Are some news outlets amplified more by algorithms than others? Does news media algorithmic amplification favour one side of the political spectrum more than the other?

Even as India celebrates reaching a milestone of 100 crore Covid vaccine doses, Snapdeal co-founder and COO Rohit Bansal on Friday lauded a man who facilitated 64 registrations for the vaccine on the CoWin portal. In a video shared on his Facebook and Twitter page, Bansal hailed Sonu Kumar as a "citizen celebrity".
Bansal said that Kumar not only helped "just co-workers and family but complete strangers too. With patience, empathy and uncanny jugaad". He added that Kumar joined him "many moons ago" and completed his open school from a parking lot.
"Education has helped this wonderful man enable others to get India back on track. Bravo! The CoWin portal on Thursday mentioned that a total of 100 crore vaccine doses has been administered so far to the eligible population under the vaccination drive in India, nine months after the nationwide inoculation programme was started to protect the people against Covid-19.
"It's a cause of significant celebration and happiness," Bansal said in the video. He said that while people just help a few around them, Kumar "bridged the digital gap" for 64 people, who were finding it difficult to register themselves online on the vaccine portal. Kumar said he doesn't feel that he has contributed much towards the 100 crore vaccine dose count. "I have been able to help only 64 people, if I was able to help more I would have been happier."
