DETECTING CYCLICITY IN SOCIAL-INTERACTION

Reviews spectral and cross-spectral analytic methods for detecting cyclicity, cross-cyclicity, and lead-lag relationships in continuous data derived from the observation of dyadic interaction. It is found that lead-lag relationships can be assessed using the phase spectrum. Spectral analytic methods are then generalized to categorical observational data (taken from a study by the author and his associates; see record 1978-20895-001). It is shown that by these methods one can derive the classical information theory definition of social communication and its distribution statistics.
