Expectancy

People's beliefs that certain consequences will follow certain actions. An example of a response expectancy is the Placebo Effect: a phenomenon which occurs when a person’s response to a treatment or response on the dependent variable in an experiment is due to expectations regarding the treatment rather than to the treatment itself.
