Jul 17, 2018 The study examines a phenomenon known as the Delboeuf illusion in relation to food. The original illusion shows how our brain can become confused by the size of objects depending on their context. 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. Jun 01, 2020 The Delboeuf illusion leads humans to overestimate food size in a small context.

Here, we studied whether domestic dogs perceive the Delboeuf illusion. In human and non-human primates, this illusion creates a misperception of item size as a function of its surrounding context. To examine this effect in dogs, we adapted the spontaneous.
A new study by Dr. Brian Wansink and Dr. Koert van Ittersum indicates that it does - or more specifically, that the color contrast between food and plate creates an optical illusion known as the Delboeuf illusion. Named after the Belgian scientist who discovered it in 1865.

This is an example of the Delboeuf illusion, first identified by Belgian philosopher and mathematician Joseph Delbouef in 1887 or 1888.

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.
