In this article, we propose a reconceptualization of the principles and parameters (P&P) framework. We argue that in lieu of discrete parameter values, a parameter value exists on a gradient plane that encodes a learner's confidence that a particular parametric structure licenses the utterances in the learner's linguistic input. Crucially,…

According to the Interface Hypothesis (IH) (e.g., Tsimpli & Sorace 2006; Sorace 2011), external interfaces are more challenging for L2 learners than internal interfaces. It is not clear, however, if linguistic phenomena associated with external interfaces are necessarily problematic and if internal interfaces are necessarily unproblematic. In…

Generative approaches to language have long recognized the natural link between theories of knowledge representation and theories of knowledge acquisition. The basic idea is that the knowledge representations provided by Universal Grammar enable children to acquire language as reliably as they do because these representations highlight the…

The induction problems facing language learners have played a central role in debates about the types of learning biases that exist in the human brain. Many linguists have argued that some of the learning biases necessary to solve these language induction problems must be both innate and language-specific (i.e., the Universal Grammar (UG)…

This article reports on an experimental investigation of knowledge of distributivity in nonnative (L2) Japanese learners whose first language (L1) is English or Korean. The availability of distributive scope in Japanese is modulated by word order and the semantic features of quantifiers. For English-speaking learners, these subtle interpretive…

Coupling a review of previous studies on the acquisition of grammatical aspects undertaken from contrasting paradigmatic views of second language acquisition (SLA) with new experimental data from L2 Portuguese, the present study contributes to this specific literature as well as general debates in L2 epistemology. We tested 31 adult English…

Data from 37 children (aged 3;1 to 6;10) and 15 adult controls support idea that poor performance on Principle B of Binding Theory is result of exposure to sentences like "I chose me" and insensitivity to contrastive stress (CS). There was a high correlation between performance on Principle B and sensitivity to CS. The Contrastive Stress…

It has been known for several decades that young children have difficulties with universal sentences. In this article, I present an analysis of the main errors that have been reported in the literature. My proposal is based on an old idea, namely, that children's errors are caused by a noncanonical mapping from syntactic form to semantic…

Presents evidence for a theory that children learning Russian at a certain age know a syntactic principle that governs the distribution of pronouns, but that they do not know a pragmatic or semantic principle that restricts the situations in which noun phrases may be contraindexed.
