If the daughter loves video games then give video game time as a reward for good behavior, and take away video game time for bad behavior.
Does this actually work? My understanding of conditioning is that it works best if the reward or punishment immediately follows the action, which the taking away of privileges doesn't really: the consequences aren't felt until later (which I imagine is why conditioning doesn't stop people from drinking even if they consistently get terrible hangovers). I seem to recall that when my parents tried this kind of thing on me it just made me like them less.
If the goal is to get the child to think about the consequences of good and bad behavior, then you're the ...
A friend of mine has a rather precocious daughter with poor impulse control, and asked if I knew any behavior games that encourage children to think out the consequences of actions before they do them.
I'm familiar with the Good Behavior Game and the like, but standard conditioning hasn't been very effective with this child in the past. She's quite clever about subverting rules when possible, and shutting down entirely when subversion fails.
Please, one suggestion per thread so that the karma thing can do its thing.
