Fig. 2: Interaction between rate and motor effector in the synchronization task.

Linear mixed model estimates for the normalized phase locking values (PLVs) and their distributions for tapping (blue triangles, solid lines) and whispering (red circles, dashed lines). The boxes display the median along with the inter-quartile range. The whiskers extend to data points within 1.5 times the inter-quartile range. Each individual point shows the model estimate for one participant (n = 62). The lines show the estimates of the random slope for the rate. **p < 0.01.
