Not OP, but they said: > Intermittent variable rewards ... will induce compulsive behavior As a dog owner this is why you need to give a variable amount of treats (sometimes zero) to your dog when they obey a command, for the "jackpot effect". For example, if I land a trick while skating it gives me a boost. Is that addictive behaviour? not sure. It gets me to exercise. My point is that variability is probably part of what gets you back to pepper planting and fishing. Intermittent variable rewards reinforcing a behaviour seems to be a fact. If this is good or bad regarding a specific activity is left as an exercise for the reader. EDIT: grammar
