This book examines coordinated verbal and nonverbal symmetry in turn-taking behavior during conversation using three modern techniques for analyzing conversational data in nonstationary time series data: windowed cross-correlation, multifractal wavelet analysis, and recurrence quantification analysis. A major goal of this work was to combine the well-established qualitative method of analyzing verbal (and more recently nonverbal) discourse known as conversation analysis (CA) with more recent quantitative methods for analyzing nonstationary time series data.
