Electromagnetic radiation from your mobile phone may impair your ability to make snap decisions, say when driving a car, an Australian study shows.
The study, which will be published in the journal Neuropsychologia, found evidence of slowed reactions, on both simple reactions and more complex reactions, such as choosing a response when there is more than one alternative.
The researchers found these effects after people were exposed to electromagnetic radiation equivalent to spending 30 minutes on the phone.
Lead researcher Professor Con Stough, director of the Brain Sciences Institute at Swinburne University of Technology in Melbourne, says the reactions tested experimentally have real-life equivalents, such as making braking decisions when driving a car.
"If you are driving a car and somebody runs out in front you, your simple reaction time is the time it takes to brake, while your choice reaction time could be the time it takes to decide between braking, turning left, turning right or hooting the horn to avoid the collision," he says.
The study's 120 volunteers received either active or 'sham' radiation emissions for 30 minutes before swapping for a further 30 minutes. This meant a total active exposure of 30 minutes, equivalent to a long phone call.
The researchers then tested the study participant's reaction times and memory using a battery of neuropsychological tests.
As well as the effect on reactions times, the study found that radiation from mobile phones seems to improve working memory, used for example when remembering a phone number long enough to dial it.
But Stough says this memory finding should be interpreted with caution because the underlying biological mechanism is not known.
Any reactions? (not violent though)
