Behavioral and affective attunement between caregiver and child are considered essential for attachment and emotion regulation (Stern, 1985). Especially sensitive caregiving is associated with behavioral and physiological synchrony during mother-infant interactions (Leclère, 2014). Brain-to-brain synchrony, proposed to facilitate communication between mothers and infants (Leong et al., 2017), is only recently being addressed in developmental research. Here, we present a dual functional near-infrared spectroscopy (fNIRS) study looking at 36 mother-child dyads to investigate whether maternal caregiving and attachment affect brain-to-brain synchrony and the quality of mother-child interaction during a problem-solving task. Wavelet transform coherence is used to assess the cross-correlation between the two fNIRS time series. Preliminary results from linear-mixed model analyses reveal a significant increase in brain-to-brain synchrony in the dorsolateral prefrontal cortex (dlPFC) and tempo-parietal junction (TPJ) when mother and child solved the task in collaboration in comparison to individual problem solving. Further decoding brain-to-brain synchrony in the collaboration condition, synchrony in both areas is associated with less time needed to solve one template. The findings highlight the complexity of neuro-behavioral synchronization between mother and child and will be further discussed in relation to attachment theory.
