Final answer:
Using within-subject design in sociological research can be time-consuming because it requires repeated measures and may not accurately represent real-world behavior as it often tests within a controlled, artificial environment.
Step-by-step explanation:
Two disadvantages of using within-subject design are that it can be time consuming and may fail to reflect real-world behavior. Using this design involves testing the same subjects across different conditions, which has several implications:
- One disadvantage is that due to the necessity of repeated testing, the process can consume a significant amount of time for both participants and researchers, which might lead to participant fatigue.
- Another issue is that while within-subject design captures attitudes and beliefs well, it sometimes lacks the ability to accurately represent behavior in real-life situations, since a controlled environment can influence participants' responses differently than their natural settings.
