Predicting Human Errors From Brain Activity

Hugh Pickens writes "Researchers report that brain activity can be used to predict the likelihood of someone making an error about six seconds in advance, with gradual changes starting as much as 30 seconds ahead of time. The team used an imaging machine to scan the brains of a group of volunteers who performed a task in the presence of distracting information. When performing correctly the volunteers' brains showed increased levels of activity in those parts associated with cognitive effort, as would be expected. However, these areas gradually became less active before errors were made and at the same time another set of regions in the brain became more active. These regions are part of a so-called "default mode network" and show increased use when people are resting or asleep [PDF]. While imaging machines are far too big and complex to be used in workplaces to monitor the brain activity of people engaged in important tasks, the team hopes to correlate errors to changes in electrical activity in the brain with electroencephalography (EEG), using electrodes placed on the scalp. If EEG features can be found that correspond to the change in brain activity, then a hat that gives warning of an imminent mistake might one day become reality. We've previously discussed similar studies of brain activity."

I don't believe it

I've seen some stupid research in my time, but actually believing you can predict errors in advance is like saying you can predict which leaf will fall off of a tree in the next 6 seconds.

I don't know. This research is more like predicting whether leaves will fall in six seconds... when it can tell a big breeze is six seconds away.

From TFS, it sounds like people are getting distracted and bored doing stupid mind-numbing tasks and when they do so, they make errors. As such, they have invented a bulky and expensive way to tell when you're drifting off (and that is fairly well correlated with making errors.)

As someone who has taken too many of these tests, the problem ends up being your mind gets bored with the whole exercise withing minutes... these test take hours. After about 10 minutes at MOST, your brain starts to wander. You can NOT focus on the test no matter how much mental effort you put into these. It simulates situations like driving a car where actions and attention become so repetitive that there is an autopilot mode that kicks in. Bit in the same regard it can't be applied logically to situations like being in a boxing ring, because in those circumstances your brain is constantly adjusting to vectors that can't possibly be predicted, therefor always being up to paying attention at the task at hand.
