They probably wouldn't say the person is moving, even though both descriptions are technically correct. But what if that person were the only one moving in a room full of people standing still?
According to research by Anna Papafragou, a professor in the Department of Linguistics in the School of Arts & Sciences, and her group, the context in which words are used can significantly influence how people interpret language and determine whether they deem a description appropriate. Their findings suggest that people evaluate verbs not simply according to their literal meanings but also according to how effectively they communicate information in a particular situation. "The kind of description you use is going to vary depending on context and how informative and relevant that description is for the conversation," Papafragou says.
This study builds on decades of psychological and linguistic studies examining how people categorize objects and choose words to describe them. The findings could inform clinical approaches to language difficulties and the development of artificial intelligence systems designed to interpret human communication. People generally prefer what linguists call "basic-level" nouns, such as dog or chair, over broader—"superordinate"—terms such as "animal" or "furniture," explains Papafragou.
For example, when shown a photograph of a dog, most people will identify it as a dog rather than an animal or a Dalmatian, even though all three descriptions might be accurate. To investigate whether similar preferences apply to verbs, linguistics Ph.D. student Ruidi Huang and undergraduate student Izzy Chapman worked with Papafragou to conduct two experiments involving 80 adults. Half of the participants viewed photographs of people performing different actions.
A cartoon character named Lion described each action using either a basic-level verb, such as "A woman is running," or a broader verb, such as "A woman is moving." They evaluated the descriptions by rewarding Lion with a small, medium or large cupcake, depending on how appropriate they considered his statement. The researchers found that participants consistently preferred basic-level verbs, giving significantly lower rewards to broader descriptions. A second experiment examined whether introducing additional visual context changed those preferences.
The other half viewed groups of four photographs depicting different actions. In some cases, all four actions could be described using the same broad verb. In others, only one action fit that description.
