Fig. 4 — Interpersonal support induces physiological synchrony related to pain reduction. (A) Synchrony comparison by condition. Three one-sample t-tests revealed that partner support induced physiological synchrony, on average, within each condition. Pairwise comparisons revealed that synchrony was higher during Handholding than Stroking. Synchrony during Handholding was nonsignificantly higher than during the no-touch Present condition. Synchrony during the Present condition was a borderline significantly higher than Stroking. (B) Increased SCR synchrony predicts lower pain ratings. Pearson correlations between pain intensity ratings and average SCR synchrony within each condition.
