Amit Varma writes in Cricinfo about choking, and how it is related to implicit versus explicit learning.

hmm...worrisome. Definitely worrisome for someone who's stumbled through life more or less on what is called "implicit learning" that is.

This may explain why for some inexplicable reason I've lost the plot at times I'm not supposed to, as also why I revel in the same ulcer-inducing conditions at a different time and place.

Actually, this does make sense. I've looked back at times in my life when I've done well, and honestly, I have no f*&^ing clue what I was thinking of then. Which makes that success irreproducible. (Heisen-success anyone?). The heartening part is, it's happened enough times for me to know that it isn't all uncertainty.

But I do need to bone up on that "explicit learning" part he goes on about.

Read the article for sure.
