Experimental studies show that children have greater difficulty with "wh"-extraction from object position than subject position, arguably an intervention effect (e.g., Relativized Minimality). In this study we provide additional evidence of a S/O asymmetry in A'-dependencies from a novel source--sluicing. The results of our first…

First written in 1986, prior to the many findings concerning the optionality of finiteness and the root infinitive phenomenon, this article attempts to extend the parameter-setting model of grammatical development to the acquisition of inflectional morphology. I propose that the Stem Parameter, which states that a stem is/is not a well-formed word…

This paper focuses on the temporal and modal meanings associated with root infinitives (RIs) and other non-finite clauses in several typologically diverse languages--English, Russian, Greek and Dutch. I discuss the role that event structure, aspect, and modality play in the interpretation of these clauses. The basic hypothesis is that in the…

The question of why language acquisition is not instantaneous is addressed in terms of two related issues: the logical and the developmental aspects of language acquisition. The role of linguistic theory and research in determining the interplay of these two aspects of grammatical development is examined. It is suggested that the…

Argues that the data used to claim that morphosyntactic development of Italian-speaking children are inconsistent with nativist, parameter-setting models of language development is irrelevant to the specific hypothesis being evaluated. (25 references) (JL)

Studied interpretation of local anaphor "sjalfan sig," the long-distance anaphor "sig," and pronouns in 55 Icelandic-speaking children and 10 adult controls. Results support an approach to binding that distinguishes the syntactic use of sig from its logophoric use and treats sig as a pronominal both in its internal structure…

It is argued that the general consensus of researchers of child language that the grammatical system underlying the child's earliest multiword utterances is semantically-based, fails to provide an adequate description of even the earliest multiword utterances, and that the most sparing account of the acquisition data must include reference to…

Outside the core grammar, the set of "peripheral" or marked properties of a language include exceptions or relaxations of the settings of core grammar and the idiosyncratic features of the language governed by particular lexical items. The core/peripheral distinction has direct implications for grammatical development in children. The…
