Lots of things influence how your dinner may tasteto you:
how it’s presented on a plate, how hungry you areand of course, your taste buds.
But researchers wanted to know if early courses—appetizers—influence the taste of a meal, and trulydo whet your appetite.
Researchers had 64 volunteers eat one of two meals.
The meals were the same—bruschetta as an appetizer and an entree of pasta with garlic andoil.
The pasta that everyone got was prepared to be only so–so.
But some of the volunteers first got a bruschetta that was made to be mediocre, while theothers got one that was stellar.
Then the volunteers rated the meals.
And people who ate the good appetizer thought their entree was even worse than did peoplewho had the middling appetizer.
The study is in the journal Food Quality and Preference.
This work builds on previous studies that have focused on the perception of food and drink,and other sensory experience.
In one investigation for example, researchers found that hearing a loud sound first then makes a soft sound seem to sound even softer.
Researchers call this effect hedonic contrast—the perception or pleasure gained fromsomething is affected by how it compares to other similar stimuli.
Maybe keep that fact in mind—or on the tip of your tongue—next time you plan your courses.
mediocre: [ˌmi:diˈəʊkə(r)] adj.平平的
hedonic： [hi:’dɒnɪk] adj. 享乐主义的
