Three-year-olds can predict a noun based on an attributive adjective: evidence from eye-tracking

This paper investigates whether three-year-olds are able to process attributive adjectives (e.g., soft pillow) as they hear them and to predict the noun (pillow) on the basis of the adjective meaning (soft). This was investigated in an experiment by means of the Visual World Paradigm. The participants saw two pictures (e.g., a pillow and a book) and heard adjective–noun combinations, where the adjective was either informative (e.g., soft) or uninformative (e.g., new) about the head-noun. The properties described by the target adjectives were not visually apparent. When the adjective was uninformative, the looks at the target increased only upon hearing the noun. When the adjective was informative, however, the looks at the target increased upon hearing the adjective. Three-year-olds were as fast as adult controls in predicting the upcoming noun. We conclude that toddlers process adjective–noun phrases incrementally and can predict the noun based on the prenominal adjective.
