摘要：The study of quantification in child language traces back to Inhelder andPiaget's (1964) work, when they found that children incurred a non-adult-like interpretation of universal quantification, with what was termed over-exhaustive search: up to the age of six or seven, children would answer no tothe question Are all the circles blue. if they saw blue objects other than cir-cles. Inhelder and Piaget (1964) interpreted this fact as indicating that chil-dren assimilated the quantifier all to the predicate, and so that they under-stood the question above as asking if all the circles are all the blue things.Another error in the child interpretation of universal quantifiers re-ported in the literature is that of underexhaustive search. In this case, supposewe have a set of circles, one of which is red; then the proposition All thecircles are blue is false; if the child considers the proposition true, discartingthe falsifying instance, we have underexhaustive search
