Follow us on social media. Only so much brain One of my favourite studies in this area was undertaken by Marcel Just at Carnegie Mellon University. Participants drove along a winding road in a rudimentary simulator, controlled via a mouse, while lying in an fMRI scanner to record brain activity.
You might also like A ban on any mobile phone use while driving should be standard for young drivers — but should it extend to all motorists? Thus a mobile conversation ie325 demand even more attention, at the worst possible time. But is using a hand-held mobile phone really that dangerous when driving?
A recent police clampdown on driving while using hand-held mobile phones caught nearly 8, UK drivers in a weekostensibly reflecting a widespread disregard of a law intended to protect all. During the dual task however, activation became apparent in the temporal lobes, reflecting the processing of the auditory messages.
Thanks to the ban, at least drivers know they are doing something illegal and potentially dangerous when making a hand-held call, so one might hope that they moderate their driving behaviour to compensate — by slowing down, for example.
Time to hang up? This increase in temporal-lobe activation corresponded with a significant decrease in parietal-lobe activation, clearly suggesting that the auditory task was commandeering attention, and diverting it away from the safety-critical driving task.
If we prioritise a conversation over road safety, then we risk a crash. The obvious implication is that hands-free phone calls may be almost as dangerous as a hand-held call. It is easy to understand why using a hand-held phone is a problem: In fact, the evidence is irrefutable. The hand-held law is necessary and important, but if it is not combined with warnings about the dangers of hands-free calls, then it may inadvertently promote an almost equally distracting and dangerous behaviour.
In one condition, participants had to engage in a sentence comprehension task while driving, similar to engaging in a mobile phone conversation. If the driver is trying to enter a fast-flowing motorway from a slip road, the passenger might, quite sensibly, shut up for a minute until the manoeuvre is complete.
One big difference between in-car and mobile phone conversations is that the passenger can see what the driver sees. Studies conducted in both simulators and in the real world have shown that drivers on a mobile phone reduce their visual scanning of the road ahead, are more likely to weave within their lane on bends, and are slower to respond to hazards.
Expert Database Find experts with knowledge in: Mobile phones Brain Driving. In the control condition, there was a lot of activity in the parietal lobe of the brain, considered to be vital for spatial processing. Many such studies have demonstrated that the demands of a meaningful conversation can account for a large amount, if not the majority, of the increased risk during driving. Fans of hands-free calls may also argue that such conversations are no different to those held with a passenger in the car.

David CrundallNottingham Trent University. Many mobile phone users now text, or intently perform some other function on their phone, while walking. For many people, this is the obvious reason why hand-held driger are banned while driving. Indeed, evidence suggests that if the driver becomes quiet at times of high demand, the remote partner may increase their level of communication to fill the silent, social void.

We cannot attend to everything in the world at the same time, so we must prioritise some stimuli over others. Available editions United States.
