Actually, they may be on to something. We could take the idea of "speak[ing] without thinking" in several directions, including the use of mindless drill, but what is intended (I think) is closer to "flow," as proposed by Csíkszentmihályi, the experience of "completely focused motivation" -- or being in the zone.
A couple of nights ago, for the first time, I tried to do a 3-minute talk about haptic research and teaching using RFC "Flow-ency" accompanying or driving everything I said. In part because I had rehearsed the talk a number of times--and it is something that I probably have "completely focused motivation" about, it went very well (at least from my perspective, if not that of the audience!) At least a couple of very partisan observers agreed with that assessment!
I have experimented with the "Flow-ency" technique with learners for a number of years. Will now get it operationalized and more "teachable" as an extension of RFC. If you still haven't signed on as a haptician, try that for a couple minutes sometime with a topic that you are truly passionate about. And keep in touch.
