Quizplus · Accepted Answer

The well-publicised plane crash constitutes a historical event that may have affected the participants' fear of flying, thereby invalidating the results of the study. Maturation refers to changes that occur naturally over time, testing concerns the impact of repeated testing on participants, and experimental effects refer to the effects of the research itself.
