Comprehension of two types of negative comparisons in children

English-speaking and Italian-speaking children between the ages of 6 years 8 months and 9 years 10 months were asked to solve instructional relation problems (i.e., to complete a picture on the basis of a sentence). Sentences contained either marked or unmarked adjectival forms in one of three types of comparative construction:positive comparative (e.g., “bigger” “più grande”),negative-equative constructions as explicit negative forms (e.g., “not as big as,” “non è grande come”), orcomparative-with-less constructions e.g., “less big,” “meno grande”) as implicit negative forms. Subjects had to focus on either the grammatical subject or the grammatical object of a sentence to complete, the picture. Three findings were consistent with predictions derived by considering syntactic and pragmatic differences between explicit and implicit types of negative comparisons. First, comprehension depended on the type of comparative construction, with the poorest comprehension for the implicit comparative-with-less construction. Second, the effect of the marked adjective depended on the type of comparison. Third, in all three types of comparison, accuracy was greater when the question was focused on the grammatical subject instead of the grammatical object.
