Example cross-wavelet plots.

<p>Wavelet power of child (top), clinician (middle) and cross-wavelet coherence (bottom) plots for an exemplary interaction. The length of the interaction was 283 s. In the top two plots, the color indicates the degree of spectral energy at different points in time of the interaction (x-axis) and at different time scales (y-axis periods). In the bottom plot, coherence magnitude and relative phase at a given time scale and a point in time are denoted by color and the orientation of the arrow (pointing right: child-clinician inphase whole-body movement coordination; left: child-clinician antiphase whole-body movement coordination; down: child leading by 90°), respectively.
