Abstract

Mother–child interaction has been characterized by a fine-tuning of behavior and physiological activity. Yet, little is known about the dynamics of mother–child physiological synchrony during early school age and their associations to positive affect. To investigate these processes, 42 mother–child dyads, with children aged 8 to 10 years, played an interactive game while their interbeat intervals (IBI) and respiratory sinus arrhythmia (RSA) were measured simultaneously. IBI/RSA synchrony was calculated using cross-correlations of the IBI/RSA second-by-second time series for lags − 3 to + 3 seconds. Mother’s and child’s individual and shared positive affect were microcoded. During the interactive tasks, IBI and RSA synchrony significantly increased compared to control conditions. RSA and affect synchrony were significantly stronger for negative compared to positive lags indicating a stronger child leads/mother follows covariation. Further, dyad’s IBI and RSA synchrony were significantly associated to mother’s and child’s individual positive affect. Our data suggest that in low-risk community samples, mothers may respond to their children’s positive affect by matching their own affect and physiology. Investigating these temporally precise, concurrent and lagged synchrony processes may open up new avenues for understanding the ways in which parent–child interactions contribute to child developmental outcomes.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Previous studies have reported IPS in both familiar and unfamiliar pairs of participants.

    “While previous studies have reported IPS in both familiar [4, 24, 43, 44] and unfamiliar [45, 46, 47] pairs of participants”
  • Previous research has established that social interaction leads to interpersonal alignment of heart rate, pupil diameter, breathing rate, and skin conductance.

    “Previous research has already established that social interaction leads to the interpersonal alignment of the physiological measures tested here—namely, heart rate [4, 44, 51, 86, 87, 88], pupil diameter [16, 17, 89], breathing rate [11, 90, 91], and skin conductance [8, 92, 93, 94].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
