Every morning I feed my cats before I leave. I have two cats. They live in the garage, and sometimes they're let inside the house.Most mornings, they manage to run into the house and I have to try to catch them.
Good morning Foxy and Tino! It's time for breakfast! Stay here.
Hey, come back here! Why don't you listen? I don't have time to catch you guys! Ugh!
Unconditioned Stimulus (food)
Come kitties! Why aren't you coming?
I'm making your food ready. Follow me to the garage.
Maybe if I whistle, it get their attention.
Whistling is the neutral stimulus.
In response to the 1st whistle, the cats give no response.
After hearing the whistle the 2nd time, the whistle has become the conditioned stimulus and the cat's hunger for food has become the conditioned response.
