There are many parallels between the role of possible worlds in modal logic and that of times in tense logic. But the similarities only go so far, and it is important to note where the two come apart. This paper argues that even though worlds and times play similar roles in the model theories of modal and tense logic, there is no tense analogue of the possible-worlds analysis of modal operators...

Modal realists should fashion their theory by postulating and taking seriously the modal equivalent of tense, or modal tense. This will give them a uniform way to respond to five different objections, one each by Skyrms, Quine, and Peacocke, and two by van Inwagen, and suggest a non-Lewisian path to modal realism. 0. Introduction The extensive parallel between temporal logic and modal logic has...

This study addresses the acquisition of the morphological markers in Persian learners of English as a foreign language. To this end, the accuracy order of nine morphemes including plural –s, progressive –ing, copula be, auxiliary be, irregular past tense, regular past tense –ed, third person –s, possessive -ʼs and indefinite articles was studied in 6...

This study was conducted to investigate the influence of teaching accurate grammar inwriting via enriched long text and short text for the elementary students atShokouhe_Farhang institute. The homogenized subjects were divided into two groups of 18and 17 participants. Using a writing exam as a pretest in order to check the students’knowledge in English past tense. The control group received the...

We present a new compositional tense-aspect deindexing mechanism that makes use of tense trees as components of discourse contexts. The mechanism allows reference episodes to be correctly identified even for embedded clauses and for discourse that involves shifts in temporal perspective, and permits deindexed logical forms to be automatically computed with a small number of deindexing rules. 1 ...

This paper investigates how linguistic expressions of time, in particular temporal adverbs and verb tense morphemes, are used to establish temporal reference in the brain. First, a semantic analysis of tense and temporal adverbs is outlined. It is proposed that computing temporal reference amounts to solving a constraint satisfaction problem. Further, the results of an ERP study are presented w...

According to Hans Kamp and Frank Vlach, the two-dimensional tense operators “now” and “then” are ineliminable in quantified tense logic. This is often adduced as an argument against tense logic, and in favor of an extensional account that makes use of explicit quantification over times. The aim of this paper is to defend tense logic against this attack. It is shown that “now” and “then” are eli...

There is substantial debate over the mental representation of regular past tense forms in both first language (L1) and second language (L2) processing. Specifically, the controversy revolves around the nature of morphologically complex forms such as the past tense –ed in English and how morphological structures of such forms are represented in the mental lexicon. This study focuses on the resul...

Usually writing teachers feel commitment to provide their learners with corrective feedback (CF) to their linguistic errors. The study investigated whether two types of written corrective feedback, indirect focused corrective feedback and indirect unfocused corrective feedback, produced differential effects on the accurate use of grammatical forms by high intermediate EFL learners. In this stud...
