A Government study into the effect mobiles have on a child's brain will "provide the evidence base with which to inform policy", the investigation's chief said.
Scamp's principal investigator Dr Mireille Toledano, from Imperial College London, explained:
As mobile phones are a new and widespread technology central to our lives, carrying out the Scamp study is important in order to provide the evidence base with which to inform policy and through which parents and their children can make informed life choices.
By assessing the children in year seven and again in year nine we will be able to see how their cognitive abilities develop in relation to changing use of mobile phones and other wireless technologies.
