Do 2nd and 3rd generation mobile phone exposures affect sensory and cognitive function in adolescents, adults and elderly?

Conference Paper


Abstract


  • There has been considerable interest in the possibility that mobile phones (MP) may

    adversely affect human sensation and cognition. In terms of sensory and cognitive function,

    studies have so far been inconclusive with some reports of improvements, some reports of

    impairments, but on the whole no consistent findings. Further to this there is uncertainty as to

    whether different age groups may be differentially sensitive to mobile phone-related

    exposures (e.g. adolescents, young adults and elderly), and whether different technologies

    (e.g. 2nd versus 3rd generation phones) may effect people differently. The present study

    addresses these uncertainties by testing cognitive function of different age-groups during

    exposure to 2G, 3G and sham conditions separately.

    Event related potentials (ERPs), which are derivations of the electroencephalogram, offer

    a sensitive means of assessing brain function. The present study employed ERPs to assess

    brain function during an auditory oddball task, which required participants to press a

    response button whenever they heard a target stimulus. Non-targets and novel stimuli were

    also presented, which enabled the assessment of neural processing associated with sensory

    processing (early ERPs to non-targets), cognitive processing (later ERPs to targets), and the

    ‘surprise’ associated with the presentation of the ‘novel’ stimuli (ERPs to novels).
