Selection maturation as a threat to internal validity is never relevant to a repeated-measures design.

Internal validity is the degree to which observed differences on the dependent variable are directly related to the independent variable, not to some other unintended variable. There are eight threats to internal validity: history, maturation, instrumentation, testing, selection bias, regression to the mean, social interaction and attrition. Maturation, this is a threat that is internal to the individual participant. It is the possibility that mental or physical changes occur within the participants themselves that could account for the evaluation results. Internal validity is defined as the extent to which the observed results represent the truth in the population we are studying and, thus, are not due to methodological errors.
