The Early Days of Cognitive Task Analysis at USC
David Perry: I wanted to start by talking about your educational background. How did you end up at USC? What did you focus on there and what were those early days of exposure to CT like for you? He says he had never set out to get a PhD or get involved in research or any of those sorts of things but ended up studying cognitive science, somewhat by accident. Perry: At the core of it is the notion that expertise is important. That one of the things that makes experts expert is that they're able to do things with very little or even no mental effort that other people can really struggle to do.
