unit 3

1. Discuss an example of a time when one of the six influences on perception caused you to misperceive someone or something in a work situation. What could you have done differently? Also, discuss a time when you were misperceived by someone else and why you believe this happened. What could you do to change that misperception?

2. Have you ever wondered why you get tired much faster on warmer days than on cold ones or why you become dizzy and weak when you are dehydrated? As you are learning, your body is more than a collection of organs. In addition to understanding where we come from and what we are made of, we must understand the role of chemicals in our body. Chemicals can help you to maintain homeostasis, but an imbalance can also disrupt this important process. Electrolytes, substances that are able to conduct electricity when they are dissolved, are some of these chemicals. Scientists have identified four main electrolytes in the human body: sodium, potassium, chloride and bicarbonate. 

On a warm day, George embarks on his first 5K run. After approximately 40 minutes, he becomes dizzy, then stumbles and falls. When emergency personnel arrive on the scene, they find him weak but awake. He complains of muscle pain in his limbs and dizziness. He mentions that before leaving his home, he ate a piece of toast and a large cup of coffee. He has not consumed any other foods or beverages since leaving his home.

In your main response, please address the following questions. What could be happening to George? How should he be treated? Based on what you’ve learned thus far, what could George have done to help prevent this situation? What factors may be contributing to George's symptoms?
