Document Summary
The prosodic specifics of a sequence (a nursery rhyme) Acquisition of knowledge about how these words combine. In languages in which function words and inflections are more salient, they are acquired sooner. Challenge: words are often learned in the context of combinations of other words. Speach stream has no silences in it, no gaps in an acoustic signal. After infants were exposed to words, infants better able to map meaning onto words. If you already know the name of the object, a novel word must refer to something else. The more featurally different the word, the more likely the infant will think it refers to (look at) the novel object. They play with the infant, using the new words they"ve learned. The proportion of the field of view predicts learning. Meaning is not necessary for the infant to start extracting word-like segments from the environment. Infants demonstrate whole object bias and mutual exclusivity.
