Reactivity refers to the potential for participants to alter their behavior or responses in response to being observed or studied. This is most relevant in observational studies, where participants may be aware that they are being observed and may modify their behavior as a result. This is less relevant in blind studies (where participants are not aware of which group they are in) or case studies (which focus on individual cases rather than group behavior). Electrophysiological studies may involve measuring physiological responses that are less susceptible to reactivity.
