All behavior is learned through reinforcement. Reinforcement is when we receive something that is motivating enough that encourages us to do a behavior again in order to reach that reinforcer again. For example, if you hate to run but your dog escaped, I bet you will start to run. The reinforcer (catching your dog!) outweighed the effort required to run. If you do end up catching your dog, you’ll most likely run the next time your dog escapes too, because you’ve now learned that running was successful to getting your reinforcer.
