In Figures 1b and 2b, the x-axes are incorrectly labelled. The correct Figures 1 and 2 appear below.

Figure 1
figure 1

Reliability of the per-pair slope estimates for sympathetic synchrony (a). Sympathetic synchrony during the knot-tying task for two example pairs (b). Effect of experimental conditions on sympathetic reactivity (c). Error bars represent standard errors of the estimated marginal means.

Figure 2
figure 2

Reliability of the per-pair slope estimates for parasympathetic synchrony (a). Parasympathetic synchrony during the knot-tying task for two example pairs (b). Effect of experimental conditions on parasympathetic reactivity (c). Error bars represent standard errors of the estimated marginal means.
