However, I though you were using the verb to mean, instead, the experiencing of some negative hedonic state.
I think that wanting to change your current state is identical with what we generally mean by being in a negative hedonic state. For reasons outlined above, I suspect that qualia aren't indepent of all the other stuff that is going on (attitudes, dispositions, memories etc.).
Studies by Kent Berridge have established that 'wanting' can be dissociated from 'liking'. This research finding (among others; Guy Kahane discusses some of these) undermines the claim that affective qualia are intextricably linked to intentional attitudes, as you seem to suggest.
I've always been more of a theoretician, but it's important to try one's hand at practical problems from time to time. In that vein, I've decided to try three simultaneous experiments on major Less Wrong themes. I will aim to acquire something to protect, I will practice training a seed intelligence, and I will become more familiar with many consequences of evolutionary psychology.
In the spirit of efficiency I'll combine all these experiments into one:
She's never seen Star Wars or Doctor Who.
She's never seen David Attenborough or read J. L. Borges.
She's never had a philosophical debate.
She's never been skiing.
Never had sex, never been hugged or even been licked by a dog!
She has so much to look forwards to...
(Though she'll be very boring for several months yet!)
