Novelty Effect

A type of threat to external validity that is similar to the Hawthorne effect. A novelty effect refers to the fact that an outcome or result may be due in part to the uniqueness of an experimental situation or testing rather than the intervention itself. In this instance, the novelty of the experiment or situation is a confounder.
