Document Summary

Identify and explain the basic hardware components that enable animals to respond to their environment. We are born knowing how to do this. Rats run from cats, they eat cheese, they mate with other rats, they feed their children. Humans respond to a knee tap at the doctor. It gives us the ability to stop a reflex from responding over time. Ex. a novel sound in your environment, such as a new ring tone, may initially draw your attention or even become distracting. After you become accustomed to this sound, you pay less attention to the noise and your response to the sound will diminish. Ex. a dog may find a vacuum very frightening at first, but after years of being exposed to it may not find it so scary. Sensation: the ability to sense relative necessities (such as food) or relative avoidances (such as predators) around us.
