Abstract Much of a child’s early learning takes place during social interactions with others. Neural synchrony, the temporal alignment individuals’ functional brain activity, is neural mechanism that may support successful interaction, but its biological origins and sensitivity to environmental factors remain unknown. This study measures coherence between 4- 6-year-old children their mothers using wearable near-infrared spectroscopy (“fNIRS”) in collaborative problem-solving hyperscanning paradigm. Best practices fNIRS data processing are incorporated optimise quantification extricate environmental- task-related effects. Results suggest physiological noise extracerebral layer artificially inflated strength both oxygenated (“HbO2”) deoxygenated (“HbR”) haemoglobin. Coherence remained stronger than individual problem solving chromophores after reduction. Phase-scrambled pseudodyad analyses supported interpretation collaboration relates dynamics interaction rather task- or environmental-related components. Strength HbO2 was positively related task performance negatively background maternal stress. HbR also stress direction results were mixed. Overall, this provides new insight into nature play.
