| Abstract: | ABSTRACT— How do infants acquire their first words? Word reference , or how words map onto objects and events, lies at the core of this question. The emergentist coalition model (ECM) represents a new wave of hybrid developmental theories suggesting that the process of vocabulary development changes from one based in perceptual salience and association to one embedded in social understanding. Beginning at 10 months, babies learn words associatively, ignoring the speaker's social cues and using perceptual salience to guide them. By 12 months, babies attend to social cues, but fail to recruit them for word learning. By 18 and 24 months, babies recruit speakers' social cues to learn the names of particular objects speakers label, regardless of those objects' perceptual attraction. Controversies about how to account for the changing character of word acquisition, along with the roots of children's increasing reliance on speakers' social intent, are discussed. |
