http://en.wikipedia.org/wiki/P3b

I found this article while researching something else and I was intrigued. Is this a neural correlate of confusion?

The P3b has been a prominent tool used to study cognitive processes for several decades. More specifically, this ERP component has played a key role in cognitive psychology research on information processing. Generally speaking, improbable events will elicit a P3b, and the less probable the event, the larger the P3b.[3] However, in order to elicit a P3b, the improbable event must be related to the task at hand in some way (for example, the improbable event could be an infrequent target letter in a stream of letters, to which a subject might respond with a button press). The P3b can also be used to measure how demanding a task is on cognitive workload.[4]

If so, awesome. Hats which actually do sound an alarm when your models are proven wrong could be arranged. I suspect that there might be things that make it not useful for that (like, if it also correlates with a bunch of other things). Seems like it's at least worth mentioning.

This sounds like it should be combined with neurofeedback so people can begin to train themselves to recognise this feeling!

Amazing.

Here's to the day when "I notice that I am confused" will be as superfluous as "I notice that I am in pain".

Yes!
