Dear Jan

Many thanks for your remarks. You have a very kind way of disagreeing.

You may have seen what I am sneaking up on.

Say you are monitoring an operation, and things begin to go badly
wrong. Presumably, there is an accompanying adrenalin hit, increased
heart rate, etc. Let's call this a 'stress step'.

Review of some aircraft accident reports reveals that the crew most
likely experienced several stress steps, the final one of which
induced apparent incompetence, or cognitive collapse. Is it possible
to train people so, by monitoring themselves, they can recognise that
the next step could put them over the threshold. Recognising that, can
they then introduce counter measure(s)?

The onset of stress arousal is not going to be in steps, most likely.
Picking the point along a steadily increasing stress gradient where
the 'go no further' boundary lies will thus be even more difficult.
Nevertheless, I happen to believe that people whose employment puts
the lives of others in their care need to be able to do this. I have
some ideas on how it could be done, for pilots, at any rate, either
solo or in a crew, but they are far from certain. Basically, you
familiarise them with their cognitive threshold. But I get so few
volunteers. They'd all rather play with the Rottweiler!

Cheers

Doug
