Various explanations have been put forth for the asymmetrical acquisition of tense and aspect morphology across categories of lexical aspect. This experiment tested the adequacy of a subset of such accounts by examining English native speakers' (n = 40) use of progressive and past tense morphology within activity and accomplishment verb frames…

A pervasive question in second language (L2) research is whether L2 learners can acquire parameterized functional features that are not instantiated in their first language (L1). While some researchers have argued for a representational deficit (e.g., Clahsen & Muysken, 1989; Hawkins & Chan, 1997), claiming that L2 learners' competence is…

Little is known about older adult language learners and effects of aging on L2 learning. This study investigated learning in older age through interactions of learner-internal and -external variables; specifically, late-learned L2 (bilingualism) and provision of grammar explanation (explicit instruction, EI). Forty-three older adults (age 60+) who…

Second language acquisition research into the effects of corrective feedback has investigated a variety of learning targets using a wide range of implicit and explicit feedback types (Li, 2010). To date, however, its linguistic focus has been limited to theoretically noticeable surface features (Carroll, 2001; Schmidt, 2001), and researchers have…

GPARS is a generalized transition network system designed for language study by both students and researchers. It generalizes the Augmented Transition Network formalism by allowing top-down, bottom-up, depth-first, breadth-first, determininistic, and nondeterministic parsing strategies to be freely intermixed.

Didascalia, a Belgian research group, has developed Verbochip, a computer program dealing with the formation and contextual uses of English tenses, based on the principle of external versatility. The content base includes various fields with information that allows the content to be implemented in a selection system that fits the user's own…

A research program was planned to develop a first, experimental computer-assisted instruction system that would permit interaction with students in a subset natural English. At the base of this system was a model of cognition that would represent the knowledge content of the material to be taught and the student's current knowledge of it. A…

This paper defines the structure of a semantic network for use in representing discourse and lexical meanings. The structure is designed to represent underlying semantic meanings that, with a lexicon and a grammar, can generate natural-language sentences in a linguistically justifiable manner. The semantics of natural English can be defined as a…

BEFORE ESTABLISHING HOW A DIGITAL COMPUTER COULD BE USED FOR DESCRIBING BASIC CONTRASTS BETWEEN AMERICAN ENGLISH AND STANDARD UKRAINIAN, IT WAS NECESSARY TO DEVELOP A SET OF SYMBOLS CORRESPONDING TO CERTAIN ELEMENTARY DESCRIPTIVE UNITS OF GRAPHEMICS, PHONOLOGY, MORPHOLOGY, AND SYNTAX AND TO APPLY THESE SYMBOLS TO ENCODING FOR THE IBM 7094. THE…

The system described in this report is designed for use as a computational tool that allows a linguist to develop and study methods for generating surface strings from an underlying semantic structure. Initial findings with regard to form-determiners (such as voice, form, tense, and mood), some rules for embedding sentences, and some attention to…
