Fatigue

Explanation:

In a Within subject design, which is a form of experimental design, involves whereby participants having all the aspect or conditions of the experiment, that is, the various stages of the stages of the independent variable: such variable that is controlled by the reseacher.

Therefore, due to participants getting involved in all the stages of the experiment, it tends to leads to FATIGUE, in the sense that, participants tend to lose interest, mentally tired or even find the research boring after involving in various stages or taking various questions of survey.

Hence, in this case, when Geraldine notices participants are failing to fully complete the last level of the independent variable. Specifically, leaving questions blank and do not appear to be placing as much effort into the study as they were in the first level of the independent variable, this clearly shows FATIGUE of the participants, and it is one of the disadvantages of Within Subject Design.
