Facebook 'enhances intelligence' but Twitter 'diminishes it', claims
Spending time on the Facebook networking site could enhance a key
element of intelligence that is vital to success in life, a
psychologist has claimed, but using Twitter may have the opposite effect

Playing 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
''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.
