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 (11:30 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 with pictures of food sells more food than the restaurant that does not have pictures.

-Dr.Grayson wants to conduct her study again,but this time she wants to conduct it in her laboratory.She wants people to feel and act the same way in her laboratory that they would when facing ordering choices in an actual fast food restaurant.To this end,she must try to enhance which of the following?
A)Experimental realism
B)Generalizability
C)Construct validity
D)Cultural relativity

Dr. Grayson wants to enhance experimental realism, which refers to the extent to which a laboratory study reflects the real-world situation it is studying. By attempting to make the laboratory setting similar to a fast food restaurant, Dr. Grayson is trying to increase the experimental realism of her study. This will help to ensure that the results obtained in the laboratory are more generalizable to real-world situations. However, while experimental realism is important, it is not the only consideration in research design. Other considerations, such as construct validity and cultural relativity, may also be important depending on the specific research question being addressed.
