Keeping up with friends on Facebook stretches the 'working memory', according to one scientist Photo: BLOOMBERG NEWSPlaying video war games and solving Sudoku may have the same effect as keeping up to date with Facebook, according to Dr Tracy Alloway.
But text messaging, micro-blogging on ''Twitter'' and watching YouTube were all likely to weaken ''working memory''.
Working memory involves the ability both to remember information and to use it.
At a job interview, a candidate will employ working memory to match answers to questions in the most impressive way.
Dr Alloway, from the University of Stirling in Scotland, has extensively studied working memory and believes it to be far more important to success and happiness than IQ.
Her team has developed a working memory training programme that greatly increased the performance of slow-learning children aged 11 to 14 at a school in Durham.
After eight weeks of ''JungleMemory'' training, the children saw 10 point improvements in IQ, literacy and numeracy tests.
A number who started off close to the bottom of the class ended up near the top.
''It was a massive effect,'' said Dr Alloway, who today gave a talk on working memory at the start of the British Science Festival at the University of Surrey in Guildford.
Video games that involve planning and strategy, such as those from the Total War series, may also train working memory, Dr Alloway believes.
''I'm not saying they're good for your socialisation skills, but they do make you use your working memory,'' she said.
''You're keeping track of past actions and mapping the actions you're going to take.''
Sudoku also stretched the working memory, as did keeping up with friends on Facebook, she said.
But the ''instant'' nature of texting, Twitter and YouTube was not healthy for working memory.
''On Twitter you receive an endless stream of information, but it's also very succinct,'' said Dr Alloway. ''You don't have to process that information.
''Your attention span is being reduced and you're not engaging your brain and improving nerve connections.''
She said there was evidence linking TV viewing with Attention Deficit Hyperactivity Disorder (ADHD) while extensive texting was associated with lower IQ scores.
Riot police stormed a 30th birthday party for just 15 people and shut it down, thinking it was a rave because it was advertised on Facebook.
Four police cars, a riot van and a helicopter were involved in the swoop on Andrew Poole's gathering for his family and friends.
He was just about to light the barbecue and had not even turned on the music when the gazebo suddenly started flapping wildly and the sound of chopper blades filled the air.
I love and live social media and therefore I help people and enterprises in how they can use social media in a way that adds value for them.
In the past I used to be a successful long distance swimmer who won several national championships and crossed the the IJsselmeer three times (a swim of approximately 25km).
In the present I am a social media evangelist at Capgemini, technological optimist, blogger and consultant.
