RESEARCH STUDY 13.3
Dr. Grayson, a health psychologist, conducts a study examining whether when exposed to pictures of food, people eat more 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 (11:30 a.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 their menu board (about two blocks away from the first restaurant). She finds that the restaurant that has pictures of food sells more food than the restaurant that does not have pictures.

Question

Quizplus · Accepted Answer

Dr. Grayson's study specifically looked at people who eat lunch at fast food restaurants, so her findings can be generalized to this population. Her study did not include people who do not eat at fast food restaurants or people who eat at other types of restaurants, so it would not be appropriate to generalize the findings to those populations. The study also only took place in downtown Chicago, so it would not be appropriate to generalize the findings to people who live in other areas.
