Syntactics of interpretation of negation: a developmental study

Two cues are considered as syntactic indicators of the focus of a sentential negation in 7- and 10-year-olds and adults. One is the articles; it is proposed that an indefinite noun phrase is taken within the scope of a negative and a definite noun phrase outside it. A second cue is position. Based on R. S. Jackendoff's (1969, Foundations of Language, 5, 218-241) and P. A. Hornby's (1971, Child Development, 42, 1975-1988) work, subjects may be expected to take the second noun within the focus of sentential negatives regardless of the articles. In Experiments 1 and 2, subjects made picture selections for sentences of the form A/the Noun1 isn't V-ing the/a Noun2 and their passives. In Experiment 3, 10-year-olds describe the scenes of the sentences of the prior experiments. Noun position and article independently influenced the focus of the negation with age trends. Developmental differences in the uses of the articles are related to the acquisition of mastery of these linguistic markers.
