Can a heavier bowl make the same yoghurt seem thicker and more filling?

Details

The researchers reported a series of experiments on how the weight and texture of packaging, tableware and cutlery influence judgments of food and drink. The central example compared exactly the same yoghurt served in bowls that were identical apart from their weight. Participants rated the yoghurt as significantly denser and more filling in the heavier bowl.

Across the experimental series, the researchers also reported effects on judgments of quality and estimated price; the abstract does not specify a direction for those effects. In a separate experiment, the texture of a yoghurt container influenced ratings of certain food-texture attributes, although the abstract does not identify which attributes or how their ratings changed. These findings do not establish that heavier bowls make yoghurt seem higher quality or more expensive.

Participants did not touch the food directly with their hands. The authors suggested that sensations felt in the hands might carry over into perceptions in the mouth, but this is a proposed explanation, not an established mechanism. The abstract does not report participant numbers or the size of the rating differences, limiting conclusions about the effect’s magnitude and how broadly it applies.
