The answer remains the same. The crucial point here is *not* what is the post hoc interest/focus from the investigator, but how the brain presumably responds to the two emotions or reward conditions. In other words, a good model should characterize the effects (brain responses) as accurately as possible. If you do believe that brain regions can differentiate large and general rewards, then the two conditions should be treated as two different effects (or regressors) in the model.
