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.

Dr. Grayson's study has a high degree of ecological validity because it was conducted in a real-world setting, rather than a laboratory. This means that the results are more likely to apply to real-life situations, which is an advantage of field studies. However, it may not automatically generalize to other situations or people, and there may still be threats to internal validity.
