FACEBOOK users may feel socially successful in cyberspace but they are more likely to perform poorly in exams, according to new research into the academic impact of the social networking website.
The majority of students who use Facebook every day are underachieving by as much as an entire grade compared with those who shun the site.
Researchers have discovered how students who spend their time accumulating friends, chatting and “poking” others on the site may devote as little as one hour a week to their academic work.
The findings will confirm the worst fears of parents and teachers. They follow the ban on social networking websites in many offices, imposed to prevent workers from wasting time.
About 83% of British 16 to 24-year-olds are thought to use social networking sites such as Facebook, MySpace and Bebo, to keep in touch with friends and organise their social lives.
“Our study shows people who spend more time on Facebook spend less time studying,” said Aryn Karpinski, a researcher in the education department at Ohio State University. “Every generation has its distractions, but I think Facebook is a unique phenomenon.”
