Reactivity refers to changes in behavior that occur as a result of being observed or participating in an experiment. In this scenario, Wally may be reacting to the presence of the experimenter and attempting to behave in a way he perceives as desirable. Attribution refers to the process of assigning causes to behavior, experimenter bias refers to the unconscious influence of the experimenter on the results, and social facilitation refers to the tendency for individuals to perform better on simple tasks in the presence of others.
