The dogs used in conditioned response experiments by a Russian scientist of the late nineteenth century, Ivan Pavlov.  In these experiments, Pavlov sounded a bell while presenting                                                                food to a dog, thereby stimulating the natural flow of saliva in              the dog’s mouth. After the procedure was repeated several times,   the dog would salivate at the sound of the bell, even when no food                                       was presented.

Now, you’re not a dog, and I don’t want to make you salivate, but as my daughter has told me, she has a Pavlovian response to rain/thunder storms. She hears them, she wants to sleep. In the short video in this post, you likely won’t have time to fall asleep, but you will have time to get your mind a little bit of rest.

So go ahead. Close your eyes for a minute, and test the theory.
