Many people are not surprised that placebos can have a positive effect on disorders that seem fundamentally psychological, including depression, anxiety, and insomnia. This matching is a matter of controlling these extraneous participant variables across conditions so that they do not become confounding variables. Table 6.2shows such a sequence for assigning nine participants to three conditions. , which means using a random process to decide which participants are tested in which conditions. Or a researcher with a sample of 60 people with severe agoraphobia (fear of open spaces) might assign 20 of them to receive each of three different treatments for that disorder.
