History refers to potential external events or circumstances that may occur during the course of a study that could influence the results. This is particularly relevant in single-subject designs where participants serve as their own controls. Changes in the environment or circumstances outside of the researcher's control can introduce variability into the data, making it difficult to determine whether changes in the dependent variable are due to the treatment or some external factor. Maturation, attrition, and testing can also be threats to single-subject research designs, but history has been noted as the most significant.
