In Alexander Technique, this retrieval strategy is an example of "end-gaining." Since in AT you're learning something new, if you to for new results with this "evoke" or other habitual strategy, rather than following the newer steps - it won't work. Your old "Magic Word" strategies are something to be avoided, mostly because it doesn't work so well when applied to new experiences and an unfamilar process.
Have to say that I'm not making a value judgment on how this works or it's effectiveness with my next observation. It's just that I've just noticed, as people use this process and get some results, then they use it in places where it could be wildly useless and somehow they "believe it's working." It has the effect of being a superstition. People are convinced it's use give a quite a powerful example of "positive thinking" for them. I think the reason this works so well is there's actually a part of the brain that begins to do something as soon as you think of it - and this is why visualization works and why you can "practice" doing something by merely thinking about it.
I've also watched people do this by telling me what something is "not." Their idea that if they leave open what it is they want, whatever it isn't will be allowed to happen on its own. That's part of Alexander Technique too - prevent what's in the way and the right thing happens as if by itself. The use of this idea as a guiding ideal of life leaves a little to be desired, I think. Without their specifying exactly what it's not, they hold the not-specifying it up as a sort of superstition. If they specify it, it will be limited and thus not a surprising enough or gratifying enough sort of experience for them.
It's sort of an interesting phenomena that I'd like to investigate more.
