This conversation analytic study investigates the use of the Japanese contrastive marker "demo" "but" as a preface to responses to polar questions. "Demo"-prefaced responses are one type of nonconforming answers, that is, responses that provide (dis)affirmation to preceding questions without yes/no-tokens. This study…

When communicating, interlocutors negotiate knowledge by proposing propositional content to be added to their shared common ground. The way in which speakers put forward propositional content -- expressing more or less confidence in its truthfulness -- may affect the way in which other interlocutors react to such content. This article examines…

We report three experiments that assess whether structural priming in a question-answer dialogue context is affected by the use of direct requests, conventional indirect requests, and nonconventional indirect requests. In Experiments 1 and 2, experimenters made phone calls to businesses and asked either "Can you tell me (at) what time you…

To secure mutual understanding in interaction, speakers sometimes explain or negotiate expressions. Adopting a conversation analytic and interaction linguistic approach, I examine how participants explain which kinds of expressions in different sequential environments, using the format "x heißt y" ("x means y"). When speakers…

The study aimed to disentangle the influence of information status and referential form on the distribution of gestures in sustained discourse. Previous research shows that new and less accessible rather than old and more accessible information, expressed by rich rather than lean referential forms, is more likely to be accompanied by gestures.…

The "given-new contract" entails that speakers must distinguish for their addressee whether references are new or already part of their dialogue. Past research had found that, in a monologue to a listener, speakers shortened repeated words. However, the notion of the given-new contract is inherently dialogic, with an addressee and the…

This study formalizes and compares two major hypotheses in speakers' choices of referring expressions: the topicality model that chooses a form based on the topicality of the referent, and the rational model that chooses a form based on the informativity of the form and its speech cost. Simulations suggest that both the topicality of the referent…

Speech and music emerge from a spectrum of nested motor and perceptual coordination patterns across timescales of brief movements to actions. Intuitively, this nested clustering in movements should be reflected in sound. We examined similarities and differences in multimodal, multiscale coordination of speech and music using two complementary…

This study examined conversational turn-taking when reading scripted dialogue versus having a spontaneous conversation. When reading, listeners waited until speakers' turns had been completed before moving to start their own turns, and gap lengths between turns were longer than those of spontaneous, natural conversation. Theatrical performance…

We introduce applications of established methods in time-series and network analysis that we jointly apply here for the kinematic study "of gesture ensembles". We define a gesture ensemble as the set of gestures produced during discourse by a single person or a group of persons. Here we are interested in how gestures kinematically relate…

Requesting plays a key role in human communication. One can request the same thing in multiple ways (e.g., "Pass the salt" vs. "Could you pass the salt?"). How do speakers determine which request form to produce? And how does this choice affect a recipient's evaluation of a request? Previous analyses of naturalistic…

Through a structured examination of four English causal discourse connectives, our article tackles a gap in the existing research, which focuses mainly on written language production, and entirely lacks attests on English spoken discourse. Given the alleged general nature of English connectives commonly emphasized in the literature, the underlying…

Referent accessibility influences expressions in speech and gestures in similar ways. Speakers mostly use richer forms as noun phrases (NPs) in speech and gesture more when referents have low accessibility, whereas they use reduced forms such as pronouns more often and gesture less when referents have high accessibility. We investigated the…

In formulating a referring expression, speakers may choose between an explicit expression (such as a proper name or a noun phrase) or a reduced form such as a pronoun. We investigated whether speakers are influenced by their conversation partners to produce full noun phrases instead of pronouns and whether this differs depending on whether their…

When two people interact, reference presentation is shaped with the intention of supporting addressee understanding, allowing for ease of acceptance, thus minimizing overall collaborative effort. To date, analysis of such "audience design" has focused largely on adult-adult or adult-child interaction but seldom on adult-teenager…
