Since Wanting and Hunger are both quantitative variables, are you sure that you want to model the interaction between Wanting and Hunger? I'm not so sure what 3dMVM would do with that.

I thought 3dMVM would not mind a missing + sign in post hoc test coding, so I'm puzzled by the fact you got the same result between tests 3 and 4.
