Melbourne, October 12, 2016: Lack of proper sleep can impact the accuracy of face identification, researchers have found, suggesting that the crucial “passport task” by officers can be affected by poor sleep.

It is often necessary to identify unfamiliar people by comparing face images: for example a CCTV image to a mugshot, or a passport photograph to a traveller.

Researchers from the University of New South Wales (UNSW) in Australia and the University of Glasgow in the UK, found that accuracy of these decisions is impaired by poor sleep.

However, the study also found that poor sleepers were just as confident in their decisions, highlighting possible implications for security and policing.

Participants were asked to decide whether two images, presented on a computer monitor at the same time, pictured the same person or two different people.

The researchers set the task to differ from the face recognition tasks most of us encounter in our daily lives in two important ways: firstly, the people pictured in the images are unfamiliar.

Secondly, the task did not involve memory, because the images appear on the screen at the same time.

Researchers said that while most people would typically expect to perform well on these tasks, many are surprised at how many errors they make.

Previous studies have shown impaired memory for faces following restricted sleep. However, until now it was not known whether lack of sleep impairs performance on face identification tasks that do not rely on recognition memory.

“We found that poor sleep in the three days leading up to the test was associated with poorer performance on the face matching test. In a separate experiment, we also found that participants with insomnia were poorer on the task,” said Louise Beattie, from the the University of Glasgow.

“Sleep disruption is common in the general population, and especially so among night-shift workers,” Beattie said.

“Here we show for the first time that performance in a crucial “passport task” is affected by poor sleep, and our research has important implications for those working in security or forensic settings,” she added.

“This adds to the literature showing poor sleep and shift work to be associated with a range of adverse health, cognitive and emotional effects,” she said.

The researchers said that poor sleep was not only associated with poorer performance, but also with higher levels of confidence in errors.

“In modern society it is often necessary to identify unfamiliar people by comparing face images. In this study we show that the accuracy of these decisions is impaired in poor sleepers,” said David White, from UNSW.

“Worryingly, although poorer sleep was associated with reduced accuracy, poor sleepers were not less confident in their responses. This has important implications for security and policing, where shift work is common,” said White. (IANS)

June 17, 2018:

Restaurateurs Prodyut and Sumana Mukherjee have not only brought Indian cuisine to the ongoing FIFA World Cup 2018 here but also plan to dish out free dinner to countrymen if Argentina wins the trophy on July 15.

Based in Moscow for the last 27 years, Prodyut and Sumana run two Indian eateries, “Talk Of The Town” and “Fusion Plaza”.

Both restaurants serve popular Indian dishes like butter chicken, kebabs and a varied vegetarian spread.

During the ongoing FIFA World Cup 2018, there will be 25 per cent discount for those who will possess a Fan ID (required to watch World Cup games).

There will also be gifts and contests on offers during matches in both the restaurants to celebrate the event.

The Mukherjees, hailing from Kolkata, are die-hard fans of Argentina. Despite Albiceleste drawing 1-1 with Iceland in their group opener with Lionel Messi failing to sparkle, they believe Jorge Sampaoli’s team can go the distance.

“I am an Argentina fan. I have booked tickets for a quarterfinal match, a semifinal and of course the final. If Argentina goes on to lift

“We have been waiting for this World Cup. Indians come in large numbers during the World Cup and we wanted these eateries to be a melting point,” he added.

According to Cutting Edge Events, FIFA’s official sales agency in India for the 2018 World Cup, India is amongst the top 10 countries in terms of number of match tickets bought.

Prodyut came to Moscow to study engineering and later started working for a pharmaceutical company here before trying his hand in business. Besides running the two restaurants with the help of his wife, he was into the distribution of pharmaceutical products.

“After Russia won the first match of the World Cup, the footfall has gone up considerably. The Indians are also flooding in after the 6-9 p.m. game. That is the time both my restaurants remain full,” Prodyut said.

There are also plans to rope in registered fan clubs of Latin American countries, who will throng the restaurants during matches and then follow it up with after-game parties till the wee hours.

“I did get in touch with some of the fan clubs I had prior idea about. They agreed to come over and celebrate the games at our joints. Those will be gala nights when both eateries will remain open all night for them to enjoy,” Prodyut said.

Watching the World Cup is a dream come true for the couple, Sumana said.

“We want to make the Indians who have come here to witness the spectacle and feel at home too. We always extend a helping hand and since we are from West Bengal, we make special dishes for those who come from Bengal,” she added. (IANS)
