Jan's cat is classically conditioned to come to the kitchen at the sound of the electric can opener. one day while jan is doing some repairs in the kitchen, she notices that her cat comes running to the kitchen every time jan uses her electric drill, which sounds similar to the can opener. in this situation, the cat is displaying: discrimination. spontaneous recovery. extinction. generalization.

The correct answer is generalization. 

Generalization refers to a concept in classical conditioning wherein stimuli similar to the conditioned stimulus also elicit a similar response. In this case, the conditioned stimulus (CS) is the sound of the electric can opener, and the response is the cat coming to the kitchen. Due to generalization, the new stimulus (sound of the electric drill) leads to the response in the cat, since this stimulus is similar to the CS (sound of the electric can opener). 

Yes all of them are right
