Dr. Rafael wanted to see if he could get his students to develop a sudden craving for ice cream. While showing to his class a short video about eating disorders, he arranged it so that a picture of someone eating ice cream would flash for less than a second every 5 seconds. Following the video, more than half of the students in the class reported having a desire for ice cream. In Dr. Rafael’s experiment, which of the following was demonstrated?
