An example you can try: Get a friend, and stand near the light switch. When you turn out lights, pupils get big to take in all the available light. So, clap, then shut off the lights repeat for a few minutes Then clap, but leave the lights on, and if you watch your friends pupils, they should get real big Another is Pavlov's dogs, which began salivating (watering mouths) whenever a bell was rung because whenever that bell rang they got food, so then their body reacted every time it rang, as if food was coming.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
