1.Becca thought her fish were boring. They became active when she fed them; but the rest of the time, all they did was hide behind rocks orsit at the bottom of the tank. So she decided that when she fed the fish, she would tap on the cover of the aquarium. After pairing thetapping with the feeding for several weeks, Becci found that when shetapped on the cover, the fish swam to the top of the aquarium and were very active.

2.A rabbit is brought into a laboratory and it initially shows no reaction when a loud tone sounds. Later, however, the tone is paired with a puff of air in the animal's eye. Every time the tone sounds, a puff of air occurs and the animal blinks. After many pairings, the rabbit blinks when the tone occurs without the puff of air.

3Your BF / GF used to wear a very unique cologne / perfume.Even though they broke up with you 6 months ago, you still get a warm feeling on the rare occasion when you smell the cologne on a stranger.
