A variety of theoretical frameworks predict the resemblance of behaviors between two people engaged in communication, in the form of coordination, mimicry, or alignment. However, little is known about the time course of the behavior matching, even though there is evidence that dyads synchronize oscillatory motions (e.g., postural sway). This study examined the temporal structure of nonoscillato...

The position of intervals and the degree of musical consonance can be objectively explained by temporal series formed by mixing two pure sounds covering an octave. This result is achieved by means of Recurrence Quantification Analysis (RQA) without considering neither overtones nor physiological hypotheses. The obtained prediction of a consonance can be considered a novel solution to Galileo’s ...

Accessibility theory (Ariel, 1988; Gundel, Hedberg, & Zacharski, 1993) proposes that the grammatical form of a referring expression depends on the accessibility of its referent, with greater accessibility permitting more reduced expressions. From whose perspective is accessibility measured? Recent experiments (Bard, Hill, & Foster, 2008; de Ruiter & Lamers, submitted) using a joint construction...

Natural language dialogue between multiple participants requires conversational grounding, a process whereby interlocutors achieve a shared understanding. However, the mechanisms involved in the grounding process are under dispute. Two prominent models of dialogue between multiple participants are: interactive alignment, a simpler model that relies on automatic priming processes within individu...

In the present study the character of slip regimes in laboratory spring-slider system under weak external periodical forcing has been investigated. We report the experimental evidence of phase synchronization (PS) in a slip dynamics, induced by the external periodic electromagnetic (EM) impact. The quality of synchronization depends on the intensity and frequency of the applied field; the corre...

A molecular dynamics simulation of a Lennard-Jones fluid and a trajectory of the B1 immunoglobulin G-binding domain of streptococcal protein G ~B1-IgG! simulated in water are analyzed by recurrence quantification, which is noteworthy for its independence from stationarity constraints, as well as its ability to detect transients and both linear and nonlinear state changes. The results demonstrat...

The study of glottalization is usually based on methods whose limited reliability in the analysis of non sustained phonation is widely acknowledged. In this study we propose a method to measure the degree of glottalization which is robust to variation of fundamental frequency and which, applied to the electroglottographic signal, does not depend on changes in vocal tract resonances. The method,...

When standing quietly, the human body is continuously moving about an upright posture in an erratic fashion. Conventional posturographic analyses that ignore structure of postural steadiness time series do not fully characterize properties of sway dynamics. Recurrence quantification analysis is a technique that can extract the dynamics of postural fluctuations through several variables. In this...

A database may contain inaccurate information. When querying such a database, one may want to impose filtering constraints so that only answers produced from reasonable subsets of the data are presented. We call the problem of producing these answers with respect to a set of filtering constraints the Reasonable Query Answers (RQA) problem. The general problem is NP-Hard in data-complexity, but ...
