Figure 2

Panels (a) and (b) show the sequence of words that have been classified according to their grammatical function. In this segment of 47 events, only 12 categories appear. 1 = silence, 5 = article, 6 = pronoun, 7 = noun, 8 = verb, 9 = adjective, 10 = adverb, 11 = conjunction, 12 = preposition, 13 = interjection, 15 = adverbial phrase, and 16 = own name. Grammar observed in original series (Panel (a)) shows typical patterns of communicative interaction between caregiver and stranger. This typical pattern is cancelled when original time series are randomized (Panel (b)).
