1. I have a power generator that comes on automatically when the power goes out at my house. The generator also runs for 5 minutes each week as part of routine maintenance. The generator motor makes a noise. The first time my dog heard the noise, he startled a bit and perked his ears up. However, after repeated exposure to the generator, my dog no longer reacts to the sound of the generator starting.
   1. Does this scenario illustrate habituation, sensitization, latent inhibition, US pre-exposure, sensory pre-conditioning, blocking, or overshadowing?
2. Continuing the story from Question #1, after several months of the generator running each week for routine maintenance, we had a storm that knocked out our power. There was a loud clap of thunder, the power went out, and then the generator kicked on. My dog was very frightened during this storm, so I worried that the next time the generator turned on for routine maintenance, he might react fearfully. However, he showed no reaction.
   1. Name and describe two reasons that could explain why my dog didn't react to the sound of the generator. One reason has to do with the timing of the stimuli, and one reason has to do with pre-exposure. Be specific with your explanation.
