Operant conditioning is a method of learning that employs rewards or punishments for behavior.
Hey, Lola please go and clean your room

I will go check on it later. There will be a prize if it is done.
The mom rewards Lola by giving her a cupcake since she cleaned her room as she was asked to do. The mom regularly rewards her for doing such task, so she is already conditioned to do it without a problem.
Here, I am rewarding you with a muffin for doing what I asked.
