A psychologist investigated desensitisation to aggression. They assessed participants' levels of hostility before and after they watched an active-shooter video game clip for 10 minutes. Using a repeated measures design, 20 participants rated the level of hostility in a single set of 15 ambiguous photographs depicting social interactions, both before and after watching the clip.
Explain how two different sets of photographs could be used in this study and why this would be an improvement.
