[quoting Marshall Jones, 8 Dec 98.b] I would add that it would depend, I imagine, on where you come down on the notion of behaviorism. Personally, I think stimulus and response gets a bad rap.
I would echo this and add that if you consider language (speech, writing, etc.) as a form of behavior, behaviorism has some very useful things to say about community and the social construction of knowledge.
Another (unrelated) point that came up was the way in which people "cheat" at games:
[quoting Marshall Jones, 8 Dec 98.a] I often play Doom in "God Mode" so I don't die.
I do too. An investigation of this phenomenon might be instructive. It appears that people tailor the parameters of the game so that the challenge fits their level, perhaps in an attempt to optimize flow (I know that I never last long in Doom without "cheating")--this suggests that we might look at building components so that learners can alter their level of challenge themselves.
