Researchers have demonstrated that dialogue-based intelligent tutoring systems (ITS) can be effective in assisting students in learning. However, little research has attempted to explore the necessity of equipping dialogue-based ITS with one of the most important capabilities of human tutors, that is, maintaining polite interactions with students,…

In the age when environmental sustainability is among the chief concerns and goals of communities around the world, a number of linguistic studies have been conducted to illuminate the roles of language in protection and destruction of ecological systems. Most of the studies, however, focus on written and/or formal discourses. The present study…

This dissertation aims to extend our knowledge of prosody--in particular, what kinds of information may be conveyed through prosody, which prosodic dimensions may be used to convey them, and how individual speakers differ from one another in how they use prosody. Four production studies were conducted to examine how various factors interact with…

Simultaneous speech and turn-taking patterns vary considerably across cultures. Research on varieties of Spanish has confirmed that frequent, lengthy overlaps within and between turns are common. In this paper it is suggested that when speakers engage in simultaneous talk, they observe Grice's Cooperative Principle by adjusting their utterances so…

The goal of this research was to use politeness theory to analyze the developing tutorial relationship between students and peer tutors in a university writing center. The study monitored two pairs of tutors and students over a period of six weeks, focusing on weeks one and six. Using partial transcripts of recorded sessions along with observation…

When speakers refer to the same referent multiple times in a conversation, they tend to follow established patterns of usage, known as "conversational precedents." Research has found that listeners expect speakers to follow precedents, and that this expectation guides their search for referents (Barr, D. J., & Keysar, B. (2002). "Anchoring…

An investigation of interrogative structures in French examined the extent to which variation in the structure of the questions was conditioned by their function. Data are drawn from a corpus containing 177 yes/no questions and 117 WH- questions. Findings suggest the following: (1) in identifying the communicative function of interrogatives, it is…

The relationship between turn-regulation, the phonetic features of pitch, and loudness is examined in a study of two recorded natural conversations in Akan. Analysis of patterns in turn-delimitation suggests that (1) diminuendo loudness, a low pitch height, and falling pitch movement are treated by turn-occupants and their co-participants as…

Explores the hypothesis that speakers formulate their requests to anticipate the potential obstacles (ability, willingness, possession of the object desired, etc.) which hinder addressees in complying with requests and that the comprehension of these requests depends on how well speakers formulate them. (SED)

Although conversational stories within one individual's corpus share the same structure, they have features that set them apart from one another. Based on the stories' general characteristics and the way they function in ongoing talk, they can be identified as: (1) durable personal experience narratives (PENs), which are often repeated during the…

The structure of televised conversations were compared with theoretical structures of such conversations, based on data drawn from commercial television soap operas. Results show that portions resemble naturally occurring speech as represented in theoretical frameworks, but others do not; implications for language teachers are noted. (17…

A theory of semantics focusing on relationships between meaning and sound patterns in language evolution is proposed. Using cognate sets from traditional comparative studies of closely-related languages in well-defined language families, the theory addresses the use and shifting of language components. The theory begins with the ego attempting to…

This analysis of repeated utterances in Japanese conversational discourse focuses on repetition as an expression of iconicity. In the analysis of a 30-minute conversation among 4 Japanese speakers, the iconic meanings expressed by both reduplication and conversational repetition are highlighted. The iconicity characteristic of conversational data…

This study investigated how native Japanese speakers use honorifics in everyday social interaction. Honorifics are affixes, words, and formulaic phrases that follow linguistic and sociolinguistic rules and are believed to mark a speaker's politeness toward an addressee or another referenced person. The honorific system is incorporated into most…

A study of the phonetics of everyday conversational interaction looked specifically at the occurrence of the "oh" particle, a signal of the receipt of new information. Focus was on the phonetic characteristics of the "oh" utterance in this context. Data were drawn from British and American recorded telephone conversations. It was observed that…
