Dr. Grayson, a health psychologist, conducts a study examining whether people eat more when they are exposed to pictures of food than when they are not exposed to pictures of food. She goes to a fast-food restaurant in downtown Chicago that has pictures of menu items on its menu board and measures the amount of food ordered during the lunch rush (11:30a.m.-1:30 p.m.) on Tuesday. On Thursday, she does the same thing but at a fast-food restaurant that does not have pictures on its menu board (about two blocks away from the first restaurant). She finds that the restaurant with pictures of food sells more food than the restaurant that does not have pictures.
Dr) Grayson decides to conduct her study again, but in the new study, she studies people at a sit-down restaurant, and she manipulates whether the menu they use at the table has pictures or not. This is known as which of the following?

A conceptual replication allows researchers to test the robustness and generalizability of their findings.
