Child and adult speakers of English, Hungarian, and Italian described nine triplets of pictures
whose elements varied along the pragmatic dimension of givenness vs newness. In the first
picture of each series, all elements were new. In the second and third pictures, one element
increased in newness and the remaining elements increased in givenness. The devices analysed
were ellipsis, pronominalization, emphatic stress, the indefinite article, the definite article, and
initialization. The results indicated (a) marked differences between the languages, (b) early
learning of the functions of the devices, (c) some changes with age, (d) a relation between
changes in givenness and newness and use of each of the devices, and (e) baseline effects in the
use of the devices.
