Have you ever made a mistake while performing a monotonous task, one that requires your concentration but seems to go on and on and on? Some mistakes might be harmless, such as dropping a sock on the way to the laundry. Other mistakes could be more serious. Driving a long distance requires your constant vigilance and attention, but make one mistake and it could be deadly.
What if there was a way to predict our making a mistake in such a task, before the mistake was made? In our driving example, such a method would perhaps result in lives saved.
When people blunder after performing the same task over and over, scientists had suspected that such lapses were due to momentary hiccups in concentration. Still, little was known about what the brain was actually doing before such errors.
To investigate further, the brains of volunteers were scanned as they performed a monotonous task - repetitively pushing buttons that matched images flashed at them.
Unexpectedly, before volunteers made errors, their brains started displaying abnormal behavior … up to a half-minute beforehand.
Excellent! Except for one little problem. Functional MRI scanners don’t exactly fit in anyone’s pocket:
The problem is the researchers scanned the brains of volunteers using functional MRI. This conventionally has patients lying down in a large tube while slowly getting probed with powerful magnetic fields and radio wave pulses — not exactly ideal helping people in everyday situations.
The article suggests that a future technology may be developed to help with this issue, or perhaps the brain signals could pick be picked up by scalp-placed electrodes or another technology, such as functional optical brain imaging (also known as functional near-infrared spectroscopy).
Regardless, this kind of research shows that if certain behaviors can be predicted, even by just a few seconds, it could have an impact in reducing possible harm caused by such behaviors.

Well, I read your article and thought it was very interesting. Unfortunately I had a brain fart and accidently voted one star instead of five stars. Sorry about that!

Wish there were one of these for people like me with bi-polar while on the job. It would save a lot of frustration and job endangerment.

It would be great to have something like that. It could be something like those electrical mechanisms they have for dogs where there is a click before the shock. If they start to get too “zoned out” it clicks and if no response, then comes the shock.
