Getting to the Core of Role: Defining Interpreters' Role Space

This article describes a new model of interpreted interactions that will help students as well as experienced practitioners define and delineate the decisions that they make. By understanding the dimensions that comprise the concept we call role, interpreters can more effectively allow participants to have successful communicative interactions

Beyond ‘Interaction’: How to Understand Social Effects on Social Cognition

In recent years, a number of philosophers and cognitive scientists have advocated for an ‘interactive turn’ in the methodology of social-cognition research: to become more ecologically valid, we must design experiments that are interactive, rather than merely observational. While the practical aim of improving ecological validity in the study of social cognition is laudable, we think that the notion of ‘interaction’ is not suitable for this task: as it is currently deployed in the social cognition literature, this notion leads to serious conceptual and methodological confusion. In this paper, we tackle this confusion on three fronts: 1) we revise the ‘interactionist’ definition of interaction; 2) we demonstrate a number of potential methodological confounds that arise in interactive experimental designs; and 3) we show that ersatz interactivity works just as well as the real thing. We conclude that the notion of ‘interaction’, as it is currently being deployed in this literature, obscures an accurate understanding of human social cognition

Conversational Alignment: A Study of Neural Coherence and Speech Entrainment

Conversational alignment refers to the tendency for communication partners to adjust their verbal and non-verbal behaviors to become more like one another during the course of human interaction. This alignment phenomenon has been observed in neural patterns, specifically in the prefrontal areas of the brain (Holper et al., 2013; Cui et al., 2012; Dommer et al., 2012; Holper et al., 2012; Funane et al., 2011; Jiang et al., 2012); verbal behaviors such acoustic speech features (e.g., Borrie & Liss, 2014; Borrie et al., 2015; Lubold & Pon-Barry, 2014), phonological features (e.g., Babel, 2012; Pardo, 2006), lexical selection (e.g., Brennan & Clark, 1996; Garrod & Anderson, 1989), syntactic structure (e.g., Branigan, Pickering, & Cleland, 2000; Reitter, Moore, & Keller, 2006); and motor behaviors including body posture, facial expressions and breathing rate (e.g., Furuyama, Hayashi, & Mishima, 2005; Louwerse, Dale, Bard, & Jeuniaux, 2012; Richardson, March, & Schmit, 2005; Shockley, Santana, & Fowler, 2003; McFarland, 2001). While conversational alignment in itself, is a largely physical phenomenon, it has been linked to significant functional value, both in the cognitive and social domains. Cognitively, conversational alignment facilitates spoken message comprehension, enabling listeners to share mental models (Garrod & Pickering, 2004) and generate temporal predictions about upcoming aspects of speech. From a social perspective, behavioral alignment has been linked with establishing turn-taking behaviors, and with increased feelings of rapport, empathy, and intimacy between conversational pairs (e.g., Lee et al. 2010; Nind, & Macrae, 2009; Smith, 2008; Bailenson & Yee, 2005; Chartrand & Barg, 1999; Miles, Putman & Street, 1984; Street & Giles, 1982). Benus (2014), for example, observed that individuals who align their speech features are perceived as more socially attractive and likeable, and have interactions that are more successful. These cognitive and social benefits, associated with conversational alignment, have been observed in both linguistic and neural data (e.g., Holper et al., 2012; 2013, Cui et al. 2012; Jiang et al., 2012; Egetemeir et al., 2011; Stephens et al. 2010). The purpose of the current study was to examine conversational alignment as a multi-level communication phenomenon, by examining the relationship between neural and speech behaviors. To assess neural alignment, we used Near-Infrared Spectroscopy (NIRS), a non-invasive neuroimaging technology that detects cortical increases and decreases in the concentration of oxygenated and deoxygenated hemoglobin at multiple measurement sites to determine the rate that oxygen is being released and absorbed (Ferrari & Quaresima, 2012). While still considered a relatively new neural imaging technique, NIRS has been well established as an efficacious and effective data collection approach, particularly appropriate for social interaction research (e.g., Holper et al., 2013; Jiang et al., 2012; Holper et al., 2012; Suda et al., 2010). We utilized hyperscanning, a technique that allows for the quantitation of two simultaneous signals, allowing us to document neural alignment between two individuals (Babiloni & Astolfi, 2012). Recent studies have revealed neural alignment between two persons in cooperative states, including alignment in the right superior frontal cortices and medial prefrontal regions (Cui et al., 2012; Dommer et al., 2012; Funane et al., 2011). This increased prefrontal interbrain alignment has also been observed in other social interactions, including joint attention tasks (Dommer et al., 2012), imitation tasks (Holper et al., 2012), competitive games (Cheng et al., 2015, Duan et al., 2013), teaching-learning interactions (Holper et al., 2013), face- to-face communication (Jiang et al., 2012), mother-child interactions (Hirata et al., 2014), and during cooperative singing tasks (Osaka et al., 2015). Interestingly, Jiang et al. (2012) showed that increased neural alignment only occurred between conversational participants when they were speaking face-to-face, but not when participants had their backs facing one another. The authors speculated that the multi-sensory information, for example motor behaviors such as gestures, was required for neural alignment to occur

Self-organization in Communicating Groups: the emergence of coordination, shared references and collective intelligence\ud

The present paper will sketch the basic ideas of the complexity paradigm, and then apply them to social systems, and in particular to groups of communicating individuals who together need to agree about how to tackle some problem or how to coordinate their actions. I will elaborate these concepts to provide an integrated foundation for a theory of self-organization, to be understood as a non-linear process of spontaneous coordination between actions. Such coordination will be shown to consist of the following components: alignment, division of labor, workflow and aggregation. I will then review some paradigmatic simulations and experiments that illustrate the alignment of references and communicative conventions between communicating agents. Finally, the paper will summarize the preliminary results of a series of experiments that I devised in order to observe the emergence of collective intelligence within a communicating group, and interpret these observations in terms of alignment, division of labor and workflow

Towards the Humanisation of Programming Tool Interactions

Program analysis tools, from simple static semantic analysis by a compiler, to complex dynamic analyses of data flow and security, have become commonplace in modern day programming. Many of the simpler analyses, such as the afore- mentioned compiler checking or linters designed to enforce code style, may even go unnoticed or unconsidered by most users, ubiquitous as they are. Despite this, and despite the obvious utility that such programming tools can provide, many warnings provided by them go unheeded by programmers most of the time.There are several reasons for this phenomenon: the propensity to produce false positives undermines confidence in the validity of warnings, the tools do not in- tegrate well into the normal workflow of the developer, sometimes the warning message is simply too esoteric for most users to understand, and so on. A com- mon theme can be drawn from these reasons for ignoring the often-times very useful information given by a programming tool: the tool itself is difficult to use.In this thesis, we consider ways in which we can bridge this gap between users and tools. To do this, we draw from observations about the way in which we interact with each other in the most basic human-to-human context. Applying these lessons to a human-tool interaction allow us to examine ways in which tools may be deficient, and investigate methods for making the interaction more natural and human-like.We explore this issue by framing the interaction as a "conversation" between a human and their development environment. We then present a new programming tool, Progger, built using design principles driven by the "conversational lens" which we use to look at these interactions. After this, we present a user study using a novel low-cost methodology, aimed at evaluating the efficacy of the Progger tool. From the results of this user study, we present a new, more streamlined version of Progger, and finally investigate the way in which it can be used to direct the users attention when conducting a code comprehension exercise

Denunciation, blame and the moral turn in public life

Public denunciations involve ritual destruction of the moral standing of the target. They are intimately related to the assigning of blame and to the alleged perpetrator’s concomitant denial of wrongdoing. While public denunciations are not a new phenomenon, what has arguably changed in recent years is the loosening of strictures on publicly denouncing immoral behavior, even when (alleged) moral transgressions happen within the remit of traditionally conceived intimate or private relationships, and the broadening of what counts as a public figure. The aim of this paper is to interrogate this moral turn in public life by examining how public denunciations are accomplished in broadcast talk, and the role they play in co-constructing and reaffirming perceived common moral ground. We conclude that while moral criticisms, such as accusing, blaming, denouncing, reproaching, and so on, are evidently oriented as sensitive actions in the public sphere, it appears that constraints on publicly denouncing immoral behavior are on the wane

When I Move, You Move: Coordination in Conversation

Researchers have been interested in the dynamics of human conversation for several decades. One major focus of this line of research has been the mechanisms by which humans coordinate in conversation. To study the coordination of conversation within dyads often requires an understanding of statistical methods, which handle time series data. Traditionally, there are no definitive standards for defining one of the important parameters in time series analysis, window size. Therefore, the purpose of the current project was to elucidate the mechanisms through which conversational coordination emerges by utilizing conversational turn-taking as the basis for choosing the appropriate window size in the time series analysis. Data from previously collected videotaped conversational interactions were analyzed for the presence of movement coordination using an image-differencing algorithm in MATLAB. Additionally, speech signals time-locked to the video segments were examined for vocal synchrony in pitch using Praat. The participants from the original study were asked to engage in three tasks designed to elicit sarcasm. Only data from one of these tasks, discussing an ironic scenario, were analyzed for the current project. There were eleven dyads each contributing one conversation and each lasting between 2 and 8 minutes. It was thought that both movement and pitch were possible coordination mechanisms, but that coordination patterns would only be uncovered by using time series windows adjusted for turn-taking rates in each dyad. Results from windowed cross-correlations revealed that participants significantly coordinated movement. Post-hoc tests revealed an effect of window size on mean correlations. Although not significant, results from the analysis of vocal coordination revealed a pattern of results similar to those from the movement coordination study. This could be due to a lack of statistical power. Interestingly, patterns of movement coordination were found strictly as a function of a vocal parameter: turn-taking. These results suggest a novel approach to the study of conversational coordination and a more crucial role for turn-taking in the emergence of coordinative structures

Turn-Taking Strategies: Alignment Development in Casual Discussion

This paper reports a conversation analysis of a 10-minute-long audio-recorded casual conversation between two Asian women and identifies the strategies they used to achieve alignment in casual discussion. It then argues that organizational patterns of conversation are context-sensitive; the turn-taking strategies adapted by participants to establish alignment can be influenced by factors such as culture and gender but ultimately determined by the communicative goal in a given speech event
