Give two examples where a within subjects design would not work. Explain why in each case.
What will be an ideal response?
Ans: There are many times when a within subjects design will not work, even with counterbalancing or one of the other designs meant to take care of context effects. For example, studies where effects may not be reversible cannot be conducted with a within subjects design. For example, if researchers are testing the effect of a drug, and the drug turns out to be a cure, conducting a within subjects design is a bad idea because we cannot give participants the drug and then go back to baseline. This is a good thing as far as the participants are concerned, but it means we cannot really show the effects are due to the drug. Another example of where a within subjects design would not work is in stages of learning where practice is not a focus. This is one reason a regular longitudinal design does not really work with studying intelligence changes with age. In these cases, participants have to take the same intelligence tests again and again so their scores can be compared. However, if you take the same test again and again, you naturally improve. This can be helped by long gaps in time between testing, but then participants drop out. In this case, a within subjects design is necessary, but is best paired with a cross-sectional to assess the effects of practice.
