Visual cues and food intake: A preregistered replication of Wansink et al.
This is a pre-registered replication of the bottomless soup bowl experiment, in which a bowl refills slowly and invisibly as the diner eats. The original is one of the most repeated demonstrations in food psychology and comes from a laboratory whose work has since been widely retracted and corrected, which is why an independent replication matters. The result supports the original claim, at a smaller effect size than first reported. People eating from the self-refilling bowl consumed significantly more soup than people eating from a normal bowl, and, as in the original, they did not believe they had eaten any more than the others. The authors' conclusion is that visual cues exert strong control over how much people eat and can override the body's own signals of fullness. This vault cites this paper rather than the original whenever the bottomless bowl is mentioned.
