This study examined the influence of sex, social dominance, and context on motion-tracked head movements during dyadic conversations. Windowed cross-correlation analyses found high peak correlation between conversants’ head movements over short (2 second) intervals and a high degree of nonstationarity. Nonstationarity in head movements was found to be related to gender of the participants. Multifractal analysis found small-scale fluctuations to be persistent, and large-scale fluctuations to be antipersistent. These results are consistent with a view that symmetry is formed between conversants over short intervals and that this symmetry is broken at longer, irregular intervals.
