Preschoolers learned a novel adjective or count noun for an object and chose between two objects that shared an object kind or a material kind property with the target object. Found that, in interpreting adjectives, four-year-olds were more likely to choose the object sharing material kind with the target if the target was familiar than if it was…

Two studies addressed the relative strengths of object kind bias and syntactic knowledge in 2-year-olds' inductions of word meaning. The study looked at children's interpretations of novel proper names for familiar and unfamiliar objects. In each study, 10 children were assigned to each of 2 conditions (familiar and unfamiliar) and shown 2 cats…

Four experiments examined three- and four-year olds' interpretations of novel words applied to familiar objects in the sentence frame "This Y is X," where X is a novel word and Y is a familiar count noun. Results indicated that preschoolers understood that the novel words were either proper names or adjectives/mass nouns. (MDM)

Three experiments examined preschoolers' and adults' understanding of distinctive semantic functions of adjectives and count nouns. Found that 4-year olds and adults, but not 3-year olds, who heard the adjective version (e.g., "a blue bird") were more likely than those who heard the count noun version ("a bluebird") to choose…
