Articulatory constraints on interpersonal postural coordination.

Abstract

Cooperative conversation has been shown to foster interpersonal postural coordination. The authors investigated whether such coordination is mediated by the influence of articulation on postural sway. In Experiment 1, talkers produced words in synchrony or in alternation, as the authors varied speaking rate and word similarity. Greater shared postural activity was found for the faster speaking rate. In Experiment 2, the authors demonstrated that shared postural activity also increases when individuals speak the same words or speak words that have similar stress patterns. However, this increase in shared postural activity is present only when participants' data are compared with those of their partner, who was present during the task, but not when compared with the data of a member of a different pair speaking the same word sequences as those of the original partner. The authors' findings suggest that interpersonal postural coordination observed during conversation is mediated by convergent speaking patterns.

Physiological evidence of interpersonal dynamics in a cooperative production task

“…We refer to synchrony of pseudo dyads as pseudosynchrony, and-using this terminology-testing whether synchrony (of true dyads) is higher than pseudosynchrony is equivalent to testing our first hypothesis that pairs of people from the same team (true dyads) have higher synchrony than pairs from different teams (pseudo dyads). This type of test has also been used in CRQA analysis of speaker-listener pairs and interpersonal coordination of posture [51,52]. We test this hypothesis with a onesided t-test, independently for each of the four psychophysiological measures, and using three different diagonal CRQA measures for (pseudo-) synchrony: ADL, LDL, and DET.…”

Investigating automatic measurements of prosodic accommodation and its dynamics in social interaction

“…They have been shown to display similar facial expressions (Bavelas et al, 1986;Hess and Blairy, 2001) and mimic gestures and body postures and movements (Condon and Sander, 1974;Meltzoff and Moore, 1977;Maurer and Tindall, 1983;Bernieri and Rosenthal, 1991;Chartrand and Bargh, 1999;Richardson et al, 2007;Shockley et al, 2007Shockley et al, , 2009). …”

Toward a Lifespan Metric of Reading Fluency

“…The nonlinear measures can be highly robust [Riley & Turvey, 2002;Webber & Zbilut, 1994, 2005Zbilut & Webber, 1992] and have been used successfully to evaluate other cognitive and behavioral phenomena where multiple factors interact in a presumably nonlinear fashion (e.g. [Shockley et al, 2007;Riley & Clark, 2003]), as we hypothesize about reading.…”
