Bilingual and monolingual children's (mean age=4;10) elicited production of the past tense in both English and French was examined in order to test predictions from Usage-Based theory regarding the sensitivity of children's acquisition rates to input factors such as variation in exposure time and the type/token frequency of morphosyntactic structures. Both bilingual and monolingual children wer...

We present an implementation of an interactive theorem prover for the basic tense logic Kt, and many of its extensions, using the generic proof assistant Isabelle. The novelty of the implementation is that we use a Display Logic formalism of Kt as opposed to a traditional Gentzen system. The prover is intended to assist in meta-theoretical studies of tense logics rather than to be a fast theore...

This paper discusses a subjunctive construction, namely, the past tense used for present state in Japanese (Teramura 1984). Unlike in Korean and other languages, the past tense marker “ta” can express an unexpected finding or remembrance at the speech time (Inoue and Ubukoshi 1997). I claim the existence of a covert antecedent clause in this construction, and that counterfactuality is involved ...

I consider two semantic issues concerning will-sentences: Stalnaker’s Asymmetry and modal subordination in Karttunen-type discourses. The former prima facie points to drawing a distinction between will and modal verbs, as it seems to show that will does not license non-specific indefinites. The latter points in the opposite direction, suggesting that will-sentences involve some kind of modality...

What are the computational and representational bases of the mental lexicon of words, and of the rules of grammar which productively combine lexical forms into larger words, phrases and sentences? ‘‘Dual-system’’ theories posit that lexical forms with non-compositional (arbitrary) sound-meaning pairings are stored in memory, whereas compositional structures are subserved by a distinct rule-proc...
