introduction I chose the topic "Placebo Effect". I heard of this topic from my sister and it sounded very interesting and I wanted to know more. I hope to learn more about the way that our brain works and how our mental state affects our health. summery The placebo effect is a phenomenon in which people experience a benefit after the use of an inactive “fake” treatment or drug which has no medical effect. Most of the time the placebo is in the form of a pill or an injection. Sometimes the patient can be affected from the treatment, positively or negatively. For example, the person's symptoms may improve. These responses are known as the "placebo effect”.We don't know for sure how placebo works but we have a number of theories. The main theory that answers the question, is that the placebo effect is due to the person's expectations. because a person expects a pill to do something, then the body's own chemistry can cause an effect similar to what an active drug would have done. placebo is commonly used when determining the effectiveness of a new treatment. Some people in a study are given a placebo, while others get the new treatment. If participants taking the active drug have an improvement over those taking the placebo, the treatment is effective. conclusion To sum up, the placebo effect is a phenomenon which can have neither negative nor positive effects. No one knows for sure how and why placebo works and that’s why we have diverse theories that try to answer the question. It's very useful and mostly used in drug research to determine whether the drug is effective or not, which shows us the importance of this discovery. reflection at the start of the project i had a really hard time finding a subject but when I finally chose the “placebo effect” to be the subject of my project I started really enjoying this. it was really fun to learn from articles and studies in English which is something that I don't usually do, especially when it's such an interesting topic. I learned a lot from this project, for example, I didn't know that placebo had been used for drug research. in conclusion, it was a fun experience and I learned a lot.
