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…

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…

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…

Speakers use speech and gestures to represent referents in discourse. Depending on referents' information status, in speech speakers will vary richness of expression (e.g., lexical noun phrase [NP]/pronoun), nominal definiteness (indefinite/definite), and grammatical role (subject/object). This study tested whether these three linguistic markers…

In spoken discourse, understanding irony requires the apprehension of subtle cues, such as the speaker's tone of voice (prosody), which often reveal the speaker's affective stance toward the listener in the context of the utterance. To shed light on the interplay of linguistic content and prosody on impressions of spoken criticisms and compliments…

Frames are cognitive structures of knowledge grounded in people's social interaction in recurrent sociocultural activities or individual incidences. Discussion concerning the knowledge in frames largely focuses on its linguistic manifestation with regard to roles and role relations in scenes. Little attention has been paid to the scriptal…

Interruptions are common in joint activities like conversations. Typically, interrupted participants suspend the activity, address the interruption, and then reinstate the activity. In conversation, people jointly commit to interact and to talk about a topic, establishing these commitments sequentially. When a commitment is suspended, face is…

A comparison across spontaneous speech collected in the 1980s and the 2000s reveals a dramatic flip between the use of "said" versus "like" as enquoting devices. The greater use of "like" is reflected in a wide variety of quotation types including reported speech, thoughts, exclamations, and sounds. There is no…

Conversation coordinates joint activities and the joint projects that compose them. Participants coordinate (1) vertical transitions on entering and exiting joint projects; and (2) horizontal transitions in continuing within them. Transitions are coordinated using project markers such as uh-huh, yeah, right, and okay. In the authors' proposal,…

A computational framework is presented for the generation of elementary speech acts to establish conceptual alignment between a computer system and its user. This article clearly distinguishes between 2 phases of the alignment process: message interpretation and message generation. In the interpretation phase, presuppositions are extracted from…
