Children are thought to learn second languages (L2s) using primarily implicit mechanisms, in contrast to adults, who primarily rely on explicit language learning. This difference is usually attributed to cognitive maturation, but adults also receive more explicit instruction than children, which may influence their learning strategies. This study…

Purpose: The current study used an intervention design to test the hypothesis that parent input sentences with diverse lexical noun phrase (NP) subjects would accelerate growth in children's sentence diversity. Method: Child growth in third person sentence diversity was modeled from 21-30 months (n = 38) in conversational language samples obtained…

The aim of this article is two-fold: to test the Aspect Hypothesis, according to which the early use of tense-aspect morphology patterns by semantic/aspectual features of verbs, and Tense is initially defective (e.g. Antinucci and Miller, 1976; Bloom et al., 1980; Andersen and Shirai, 1994; 1996; Robison, 1995; Shirai and Andersen, 1995;…

Examines arguments that language comes from innate, abstract knowledge of universal grammar that signers use to create new grammatical features. (12 references) (CK)

Analyzes the speech of a German-French bilingual boy and observes two major developmental phases: (1) one characterized by object drop similar to that seen in Chinese; and (2) one characterized by the acquisition of the object clitic paradigm and a shift to an adult-like morphological licensing mechanism.

Addresses phenomena exhibited by young children such as suffixed and free articles, double definiteness, genitives, pronouns, and "nominal style." Shows that analysis of these early data must invoke at least one functional projection above the noun phrase. Findings argue against any claim about the universal absence of functional…

Focuses on the acquisition of negation in American Sign Language (ASL) and the developmental relationship between the communicative and grammatical (or linguistic) headshakes for negation in deaf children acquiring ASL. Results indicate that the systems for communication and language are differentially mediated. (35 references) (Author/CK)
