Although cross-linguistic research on second language tense-aspect acquisition has uncovered universal tendencies concerning the association between verbal semantics and tense-aspect markers, it is still unclear what mechanisms underlie this link. This study investigates the acquisition of two imperfective aspect markers ("-ko iss-" and…

Cross-linguistic research on the development of tense-aspect marking has revealed a strong effect of lexical aspect. But the degree of this effect varies across languages. Explanation for this universal tendency and language-specific variation is still an open issue. This study investigates the early emergence and subsequent development of four…

The relationship between prototype meanings and frequency of use is investigated with a view to establishing a foundation for the problem of "prototype acquisition." One polysemous basic verb, "put," is used in this study of native speaker discourse, and implications for both prototype theory and the acquisition of polysemy are…

Focuses on Elman's (1990) statistical analyses of the hidden unit activation patterns in his simple recurrent network on sentence prediction, first to highlight the feasibility of such analyses and then to show how connectionist explanations contribute to the development of effective explanatory theories. Argues for the evolutionary nature of…
