New research indicates that the sound of a snack's name can shape how full people expect it to make them. In a study involving over 600 participants, scientists discovered that people associate certain sounds with size, which in turn affects how they perceive a food's weight and satiety. For example, participants expected snacks with names like "Boge" to be heavier and more filling than those with names like "Tikee." This phenomenon is connected to the "mil/mal effect," a concept introduced by German psychologist Wolfgang Köhler in 1929. It suggests that sounds like "ee" or "t" are linked to smaller sizes, while sounds like "oh" or "b" are associated with larger sizes. The study used fictional brand names for a variety of snacks, both healthy and unhealthy, such as oatmeal and potato chips. Each food type was assigned a name, and participants rated how heavy and filling they expected the food to be. The researchers also took into account the length of the names, participants' preference for them, and how easy they were to pronounce. Interestingly, whether the food was healthy or unhealthy did not influence how the name's sound affected expectations of fullness. Although the study found that the sound of a snack's name influences perceptions of how filling it is, it did not find a significant effect on people's willingness to buy the snacks. However, the researchers noted that buying behavior depends on a person's current goals. For example, participants were more likely to buy snacks with "large" names if they were imagining a friend who prefers heavy, filling food, and more likely to buy snacks with "small" names if they were imagining a friend who prefers lighter, leaner food. The study also opens the door for future research into whether product names affect how full a person actually feels after eating. Researchers pointed out that expectations can influence real experiences—so if someone expects a food to be filling, they might feel more satisfied after eating it than if they expected a light snack. Additionally, future studies should look at real products instead of just verbal descriptions, as factors like packaging design, color, and shape can also influence perception.
