In Korean language, questions containing ambiguous wh-words may be interpreted as either wh-questions or yes-no questions. This study investigated 43 Korean three-year-olds’ ability to disambiguate eight indeterminate questions using prosodic and visual cues. The intonation of each question provided a cue as to whether it should be interpreted as a wh-question or a yes-no question. The questions were presented alongside picture stimuli, which acted as either a matched (presentation of corresponding auditory-visual stimuli) or a mismatched contextual cue (presentation conflicting auditory-visual stimuli). Like adults, the children preferred to comprehend questions involving ambiguous wh-words as wh-questions, rather than yes-no questions. In addition, children were as effective as adults in disambiguating indeterminate questions using prosodic cues regardless of the visual cue. However, when confronted with conflicting auditory-visual stimuli (mismatched), the quality of children's responses was less accurate than adults’ responses.

In many of the first English headed which-relatives, which has an NP complement. Using distributional tests grounded in contrasts revealed by research in formal semantics, we demonstrate that the presence of an NP complement forces a nonrestrictive interpretation of the relative, while ‘bare’ which-relatives may be restrictive or nonrestrictive. We situate this finding in relation to both the formal semantics of relative clauses, and the history of wh-relatives in English.
