Question

Every morning a graduate student turns on the light in the laboratory and then feeds the fish in the aquarium. After a couple of weeks of this routine, the graduate student notices that the fish come to the surface to feed as soon as the lights are turned on. The behavior of the fish is a result of _____.

Answer 1

I believe the answer is: Classical conditioning.

From the example above, the light is a neutral stimulus while the food acted as a biological stimulus that cause the fish to go up. After pairing the light with the food for a long period of time, the fishes would interpret that light would always mean that they would obtain food, which make them automatically go to the surface everytime they see the light.
