This can mean holding situation or task variables constant by testing all participants in the same location, giving them identical instructions, treating them in the same way, and so on. It can also mean holding participant variables constant. Netteta disadvantage of holding a variable constant is that it limits an experiments external validity true One general concern for within-subjects research is that participation in one treatment condition may influence an individual's scores in a later treatment condition.
