: How do expectations affect behavior and perception I . Introduction

This seeks to answer the question : `How do expectations affect our behavior and perception ?` In response this takes the position that positive and realistic expectations of ourselves and of other people produces good behaviors and perception . The placebo effect and Pygmalion effect concepts will be used to defend the position taken

II . How Our Own Expectations Affect Our Perception

a . Placebo /Nocebo Effect

Placebo effect is

the term used in medical science to signify the beneficial and healing effects of what appears to be there as medicine or otherwise but in reality there was . There is a sense of faith healing manipulation that is happening to the patient because of the expectation of the patient that he or she will get well with what is taken in or done or seen or undergone as prescribed by a doctor

There is therefore a case of subject-expectancy effects or placebo effect that occurs when a patient 's symptoms are changed in some way an otherwise immobile treatment , due to the patients ' having expected or believed that what was done will come to pass or will work . While there are those who will view this concept as an extraordinary aspect of human functioning there are also those who consider it to be just an illusion without basis in science and in research

To be research-based on the issue it may be appropriate to cite Talbot who reported an experiment done by a surgeon named J . Bruce Moseley , in 1994 . In said experiment , Moseley had 10 patients scheduled for an operation intended to relieve the arthritis pain in their knees Since the patients were men who weren 't ready to consign themselves to the rocking chair yet , as most of them middle-aged , they had decided to take a risk and volunteer for a study that must have sounded , when Moseley first told them about it , rather peculiar ' All them would be wheeled into an operating room at the hospital , draped , examined and anesthetized and would be dispatched to the recovery room and sent home from the hospital by the next morning equipped with crutches and a painkiller . Not all of them would undergo the whole process since two of the men of the ten men would undergo the standard arthroscopic surgery for their condition by the scraping and rinsing of the knee joint while three would just have the rinsing alone and the remaining five would have not have the surgical procedure at all . It was therefore the five that would be a placebo , an exercise in just pretend

The idea was to have the arthroscopic knee surgery that normally requires general anesthesia and of course carries risks as compared to the placebo procedure which requires only a tranquilizer and therefore it could be cheaper . The trade off there was clear that if patients may have a favorable respond too...
