Profiling turns in interaction: discourse structure and function

Abstract

Turn-taking provides a basis for comparing interactions in different communication environments, and this paper demonstrates that readily observable features of turns can be linked to principles that organize and manage the interaction. Results are based on 150 decision-making interactions elicited in a face-to-face environment, an asynchronous, e-mail environment, and several types of synchronous computer-mediated environments. We show that three features of turns can be linked to discourse structure and function. First, as turns increase in size, participants switch from serial to parallel strategies to organize their decision-making. Second, pivot turns, which are turns that are much shorter than the turns that precede or follow them, can reflect the discourse functions of the relevant turns. Finally, turns can be used for measures of dominance based on turn size. We conclude that designers of communication systems can take advantage of peoples' ability to develop effective strategies for packaging messages in different environments. 0-7695-

The effects of explicit referencing in distance problem solving over shared maps

“…Also many scholars have detailed the role of persistence in communication [4,10,18,24]. Dialogue persistence has many effects on collaborative work: it reduces the cognitive load by providing an external representation of jointly shared information; it provides a means for pairs to parallelize communication and actions [15], and it affects collaborative task performances [24].…”

A note on the Genitive of Quantification in Polish and derivational phases

“…Unlike the infrequent use of emoticons found by Baron (2008) (Condon and Cech, 2001). In our study, participants mainly expressed their emotions online through facial expressions of smile or frown to express laughter, surprise or approval.…”

Digital Business Discourse

“…Conversational coherence (or the lack of it), for example, has received considerable scholarly attention Lam & Mackiewicz, 2007;Woerner et al, 2007; see also Markman in current volume), as well as the communicative effects of multitasking and multiple concurrent conversations Reinsch et al, 2008;Rennecker & Godwin, 2003;Turner & Reinsch, 2007) and the problematic nature of turn-taking (Condon & Cech, 2002;Hancock & Dunham, 2001;Markman, 2005;Simpson, 2005b).…”
