The Placebo Effect

A placebo effect can affect how some people feel. The statistics show that placebo effect work on 1 of 3 people. A placebo can change the symptom that a person is having, that is called the placebo effect. Normally the term placebo effect is meant only for the beneficial effects a placebo has on reducing symptoms.(Szabo, A. 2013) The placebo effect usually lasts only a short time. If the placebo effect works scientist, doctors, and researchers have found that it must have something to do with

Unlike conventional medication, the only part of the body affected during the placebo effect is the brain. (The mind and the body are connected and therefore ill people taking placebos often feel physically better). Typically, the person who is receiving the placebo from the doctor thinks he/she is getting real medicine. The client will go through the usual process of getting the treatment; seeing the reliable doctor, taking in medicine at specific times and amounts. All the normal rituals of treatments are preserved. The patient’s expectation of getting better while taking the placebo will be as high as when a real medicine is taken(H.K. Beecher 35% of 1082 patients) (A Comprehensive Review of the Placebo Effect: Recent Advances and Current Thought - Annual Review of Psychology). Numerous pieces of research have shown that people taking a placebo felt as good as people taking the actual medicine. Research is ongoing on how the placebo exactly works. “Indeed, there exists not a single but many placebo effects, with different mechanisms and in different

In the last section of the article the author explains the many issues that have arisen with the discovery of the placebo effect and the many challenges that the placebo effect faces before it is accepted as a common medical practice. One major issue the author brings up is the fact that the placebo effect is not the same for everyone. The author explains that not everyone can take a placebo and expect positive results. In order to explain this variability in the article the author cites Robert Trivers, an evolutionary biologist, of Rutgers University. Trivers explains

A debate rages in psychology, but it is not one of the usual kind, dwelling on a specific aspect of the mind or a new drug, but a controversy dealing with the very foundations of psychology. The main issue is in determining what treatments for patients are valid. Some feel that they must be empirically- supported treatments, treatments backed by hard data and scientifically supported. Others feel that this standard for treatments is much too confining for the complex field of psychology. The American Psychological Association President Task Force on Evidence-Based Treatment came out with a plan for psychology that effectively maintains a high scientific standard but allows for a variety of research designs to be used in determining

A placebo substance is an inert substance that should not directly cause any positive or negative changes in our health. These pills have no medicine in them and the patient gets well. To understand the placebo affect you need to understand the power of the brain. More than half of the population appears to have a positive experience from the placebo effect. Why doesn’t the rest of the population respond in the same way? The human brain is capable of preventing even the best well thought-out drug, medical procedure, therapy or nutritional program from working. Then why do we need supplements of medicine to feel better or reverse disease? Most diseases are related to nutrient deficiencies, chemicals, parasite or metal toxicity.

“A placebo effect is defined as the psychological or psychophysiological effect produced by placebos.” (Shapiro & Morris, 1978)

“The power of placebos has been recognised for improving numerous medical conditions”(Fernandez 2001). However, there is still much speculation as to how the underlying mechanisms of an inert substance manage to instantiate that improvement. To better understand the role of placebos in treatment, a 2001 study of the placebo effect on Parkinson’s disease was conducted.

This is strong, clear and very persuasive evidence that Kennedy was speaking of an outcome that had been totally generated by a subject's negative expectation of a drug or ritual's administration, which was the exact counterpart of a placebo response that would have been generated by a subject's positive expectation.

A placebo effect is a real response to a fake treatment. For example, you give someone a nonalcoholic beer and the response is that they act drunk. The whole point of a placebo effect is to make it seem like an actual treatment. If it does not seem like a real treatment then it leads to confounding, where the effects of two variables cannot be identified. In an experiment, researchers must have an experimental and a control

c) Classical conditioning could help patients reduce pain and anxiety through the use of placebos. For example the use of pills and injections that have no active ingredients or treatments that have no direct physical effect on the problem. The bigger and more impressive the placebos are, the stronger their psychological effects are.

In this essay I will begin by explaining the five major points of the placebo effect, such as the understanding of placebo, the history, phenomenon, experiments and case studies. Placebos are used in everyday life, from it being your doctor or even a commercial you've seen on the tv. Do we really need prescribed medication or do we just think we do?

There has been knowledge of a placebo trail that dates back to 1784, the first trial was under the direction of Benjamin Franklin. Also, it has been said that during the Second World War, Henry Beecher a medic met with two hundred seriously injured soldiers, still able to talk. Beecher offered each soldier morphine and they refused, because they were simply happy to be alive. Afterwards Beecher remembered that before the war he experienced patients with similar injuries that begged for morphine and healthy soldiers complained about minor pain. He concluded that the difference had to do with emotions and expectations of the soldiers as to how they would heal. I believe the placebo effect produces positive results ultimately based on the patient’s individual beliefs, emotions and expectations during the time of their illness. Furthermore, positive thinking is a mental attitude that is usually referred to as optimism. It has been suggested that optimism could appear to be a hereditary trait because it is actually a manifestation of combined traits that are

A debate rages in psychology. It is not one of the usual kind, dwelling on a specific aspect of the mind or a new drug, but a controversy dealing with the very foundations of psychology. The issue is determining how psychologists should treat patients and on what psychologists base their choices. Some feel that they must be empirically-supported treatments, treatments backed by hard data and scientifically supported. Others feel that this standard for treatments is much too confining for the complex field of psychology and that many good treatments cannot be backed by hard data. The American Psychological Association President Task Force on Evidence-Based Treatment came out with a plan for psychology that effectively maintains a high

In total, the results of 1460 patients receiving antidepressant medication and 858 receiving a placebo sugar pill were analyzed. This analysis combined the results from these 19 different studies and generated an effect size (which is calculated as the mean of the experimental group minus the mean of the control group, divided by the pooled standard deviation SD). Once Kirsch and Sapirstein subtracted mean placebo response rates from mean drug response rates, they found a mean medication effect of 0.39 SDs (1). For each type of medication, the effect size for the active drug response to drug response is between 1.43 and 1.69, and the placebo response is between 74% and 76% of the active drug response. This means that 75% of the effect attributed to the perceived use of anti-depressants was due to the placebo. The perception of clinical benefit from antidepressants was largely attributed to the perceptions of the mind, and not to the actual chemical make-up of the pills patients were taking. The placebo effect shows us that the mind heavily influences our perceptions of wellness and health.

While thinking for a question for Science Fair, Tamir and I wondered: What are the limits of the Placebo Effect? While we know it can stop some pain, I would like to see how we can push it. So we decided to try and test this ourselves. We will be applying headaches to people through music, and other means. We will then use a pill that will either be Tylenol or a sugar pill and see if they have a reaction to the [sugar] pill after 45min-1hr. After that, we will ask them a few questions on how they are feeling, how much pain they are in, and if the pill helped them at all. We record this information and see how it affected a large group of people and the differences between groups.
