The elaborate on the Schultz paper, dopaminergic reward feedback mechanism is for unexpected reward only. Repeated stimulation depreciates the neuronal signals.

A take home message from this is that an ideal diablo 2 drop has a expected drop time of T, and should never change. The reward, of course, can come from increased benefit of character strength, or from the rare item itself (Herald of Zakarum + Barnar Star ftw).

It seems to me like the T for Diablo 3 is much greater than that of Diablo 2, and because pretty much set items and unique items are non-existent, the satisfaction of getting the item from drops is also non-existent. Alas, the AH allows you to gain strength when you are stuck, but because the time it takes you to go to AH is not a function of T itself, since you can go whenever you want, it does not really contribute to the over all game reward mechanism.

Not to mention the horrible infrastructure they have built for the AH as Lewisham mentioned.

As I'm still working through this stuff, and am certainly no psychologist or neurobiologist, did I say anything above that was contradictory to this? It sounds like you know more than I do about the subject (I'm dabbling in it for my Computer Science thesis) and I'm always paranoid that I'm overstating or overgeneralizing some experiment result.

Oh no, you did not contradict it at all. It is one of the vital point that was pointed out in the paper, and I wanted to make sure anybody else who don't having interest in reading the actual paper to have an opportunity to get this particular point across. I'm a researcher in a neuroscience lab, and this is one of the foundational paper into modern understanding of reward mechanism. Kudos to you for linking it here :)
Dopamine doesn't just spike at unexpected "rewards," though. It can also spike at surprising loud noises, etc.
