1 Theeraporn Ratitamkul, University of Illinois and Adele E. Goldberg, Princeton University Introduction How do young children learn verb meanings? Scene observation is not sufficient (e.g. Fisher et al. 1994; Gillette et al. 1999). Syntactic evidence helps (e.g. Landau & Gleitman 1985; Naigles 1990; Fisher 1996, 2002). What happens when syntax does not reflect semantics? Even in English, an important cue, the number of arguments, is not always reliable. I pushed, but it did not move. In Thai, arguments are readily omitted when they are recoverable from discourse. Khaw tham dii khruu cUng chom He do well teacher then praise ‘He did well, so the teacher praised (him).’ How is verb meaning acquired when an object argument is omitted? The puppy blicked quickly. Then, the kitten fell down. Intransitive act with 1 participant? Or transitive with missing object? Discourse context? 2-year-olds use discourse/pragmatic knowledge to determine when arguments can be unexpressed (Allen 2000). 3-year-olds rely on cues from discourse to interpret the referent of an ambiguous pronoun (Song & Fisher 2005). 6-year olds pay attention to the listener’s knowledge of situational context when using adjectives (Nadig &Sedivy 2002). Do children also use discourse context to figure out verb meanings? An apparently intransitive verb might be taken as transitive if there is a second element mentioned in the local context. Method Study 1: Thai-speaking children 28 4-year-olds (3.9 to 4.9, M = 4.3) 28 5-year-olds (4.9 to 5.7, M = 5.1) Study 2: English-speaking children 16 5-year-olds (4.9 to 5.7, M = 5.2) Same subject A kitten and a puppy were playing tag. The kitten was running behind the puppy. The kitten was running very fast. The puppy blicked hard. Then, the puppy fell down. Then, they both laughed and laughed. Results Discussion and Conclusions Conclusions Young children are able to draw on discourse context to determine the argument structure of an unfamiliar verb. The influence of discourse context is not restricted to children acquiring languages in which argument omission is common (e.g., Thai, but is true of English-speaking children as well). Discourse context functions as additional cue to verb interpretation. References Allen, S. (2000). A discourse pragmatic explanation for argument representation in child Inuktitut.

Cognition, 52, Boston University Conference on Language Development, Boston, MA, November 3-5, 2006 Syntax also matters. 46% of Thai children and 38% of English children only produced intransitive enactment. Transitive interpretation was more likely when the event described in the subsequent sentence could be causally related to the sentence with a novel verb. This interpretation increases discourse coherence. Practice trials Enactment of 7 sentences (known and nonsense verbs) Test trials 4 short stories, each of which contained a nonce verb presented in intransitive frame (N+V+ADV) Stories varied in whether the sentence immediately following the target sentence shared the same or different subject as the target sentence. Subject of the target sentence had also appeared as subjects in previous sentences half of the time. Task: to act out target sentence after the story was heard, using toy animals Different subject A kitten and a puppy were playing tag. The kitten was running behind the puppy. The kitten was running very fast. The puppy blicked hard. Then, the kitten fell down. Then, they both laughed and laughed. Why 2-participant acts? “The puppy blicked hard. Then, the kitten fell down.” blick (agent, patient) – interpreted with omitted patient Discourse affects verb-argument structure interpretation. Thai- and English-speaking children both acted out intransitively expressed events as semantically transitive more often when the subject of the novel verb was different from the subject in the immediately following sentence. * *
