On the development of null implicit objects in L1 English

Abstract

AbstractThis article explores a defining property of implicit null object constructions, and how this property emerges during the L1 acquisition process. Implicit objects are non-referential and characterized by a strong semantic association between a null N in object position and the contents of the verb root. By means of an elicited production study, we examine children’s sensitivity to this association in terms of the typicality of implicit direct objects and of their use in a potentially contrastive context. Participants were 73 English-speaking children (between the ages of 2;09 and 5;08) and 20 adult controls. Our results show that children make a distinction between implicit objects with typical and atypical objects—even in scenarios where a previous use introduces a potential contrast—but at rates that differ from those of adults. This suggests an incomplete knowledge of the target properties of null objects and indicates that children use a referential null N until later in development, when the selectional link between V and the null object becomes entrenched and hyponymy with the verb root becomes the sole source of recoverability. We draw implications about the co-development of verb meaning and the null object construction.
