Thesecorrelations may reflect interdependence (i.e. coordination) among components at various scales of structure anddynamics (e.g., neurons, cortical columns, brain areas, brain-body interactions). Two experiments tested whetherlong-range correlations emerge when two people interact. In experiment 1, perceptual-motor coordination wasinvoked by instructing participant pairs to coordinate uttering the word ”mom” in alternation with key taps. Inexperiment 2, semantic coordination was invoked by alternating free word associations (e.g. one says ”cat”, theother says ”dog”, first says ”collar”, second says ”shirt”, and so on). Fluctuations in series of mom-tap intervals werelong-range correlated. Long-range correlations were also found in semantics fluctuations of free word associations,the latter being weaker and derived from lexical co-occurrence statistics. Results indicate that common principles ofcoordination apply across individual and dyadic scales of perceptual-motor and cognitive performances.655
