People's anxiety levels will be tested through heart rate. The resting heart rate of 30 people will be measured, then the test group will be split in half. The first 15 subjects will be told that they will watch a scary video. And for the last 15 we won't tell the subjects anything about what will happen in the video. You will be asked a series of health questions that have nothing to do with our project. The goal of this project is to record any changes in heart rate due to anxiety, anticipation, and being caught by surprise. Anxiety is fear. It's a psychological problem that starts in the brain, when humans see people looking at them and start to think they're being judged. It is immediately assumed that what they think is bad. Scientists targeted a brain chemical involved in understanding fears that already exist and containing them (Cimons). It turns out that the lack of this chemical means that those without it will “forget” to be afraid in times of trauma (Cimons). These tests were conducted on mice but have been shown to have the same effect on humans (Cimons). The goal of the lab is to see whether people will be less, more, or have the same level of sudden fear when they are told that they will see a video that will affect them and when they are simply told that they will watch a video. Their resting heart rate will be tested and then a video will be shown to them. Once they watch the video, their heart rate will be tested again and record any changes that have occurred. Thirty people were randomly chosen for this experiment. They weren't chosen for a specific reason, they were close to where the test was taking place in... middle of the document... suddenly.
