The cohort effect is a special case of the history effect in which the dependent variable is influenced by the shared experiences of members of a particular age group or cohort. This can create differences in outcomes for different experimental groups that are not directly related to the independent variable being manipulated. The Hawthorne effect refers to a change in behavior that occurs because subjects are being observed or studied. The testing effect refers to the fact that repeated testing or assessment can itself influence the dependent variable. The instrumentation effect refers to changes in the measuring instruments or methods used in an experiment that can influence the dependent variable.
