You could consider using inducement which means:
something that gives you a reason for doing something and makes you want to do it
a motive or consideration that leads one to action or to additional or more effective actions
Example:
English Language and Usage offers reputation points and badges as an inducement for users to keep visiting the site.
[Merriam-Webster]
Edit: Your example makes me wonder if inducement is the right word. In that case, you could consider using reinformcementreinforcement which means:
a strengthening of a specific behavior due to its association with a stimulus. Reinforcement is an important part of operant or instrumental conditioning. A reinforcer is the stimulus that strengthens the behavior, in contrast to punishment that weakens the behavior.
Your new example:
Our parents and teachers used reinforcement to reinforce our routines, rewarding every useful contribution (as positive reinforcement or reinforcer) and penalizing unproductive actions (as punishment).
