Applications of the Delbouef Illusion
Which circle below looks bigger?
- Our main contention is that the Delboeuf illusion biases consumers’ ability to accurately determine how much food they need to serve to reach the target serving size they would otherwise typically serve and consume. Basically, when our plate is large, we sense a large gap between the edges of the serving size and the plate.
- Jul 12, 2018 Zitron-Emanuel and Ganel presented examples of the Delboeuf illusion to two groups of experimental participants. One group was mildly food-deprived, after abstaining from eating for 3 hours prior.
Sep 12, 2019 The idea is based on something called the Delboeuf Illusion, which claims that using a smaller plate will not only help to serve less food, but the portion will actually appear larger and more filling. In turn, you will feel like you’ve eaten a lot while actually eating less.
Having already learned about the Ebbinghaus illusion, you were probably right in guessing that the circle with the ring around it appears larger than the non-surrounded circle. This is an example of the Delboeuf illusion, first identified by Belgian philosopher and mathematician Joseph Delbouef in 1887 or 1888. Modern psychologists have tested this illusion in various experiments, including one to determine if eyeshadow makes eyes look bigger (it does), and others to determine if the quantity of food on a plate looks larger if the plate is smaller.

Studies by Koert Van Ittersum and Brian Wansink[1] at the Cornell Food and Brand Lab have studied the effect of the Delbouef illusion on eating and serving behavior. In several different experiments, they measured if people would take more or less than a typical serving size depending on the size of their plate, the color of the plate, the color of the tablecloth, and how much they knew about the Delboeuf illusion.
