There are different types of reinforcement? Which one do you mean here?. I think for example positive reinforcement and negative reinforcement have a great impact in brain activity and social life.
Reinforcement comes after you have taught and find that students may still need some additional examples in order to master the skills, knowledge, and attitudes taught. You can reinforce with additional practice exercises or home work.
Reinforcement learning is learning where the "learner" is presented with some form of "reward", normally refers to machine learning. The systems learns so that to maximise this cumulative "reward", just like live forms behave. Good luck with robotics!
