Key Points

This research aims to determine if laughing together in pairs of five-year-old children induces physiological synchrony.
N = 73 same-sex dyads of five-year-olds watched funny or neutral animal videos in a lab setting.
Heart rates were recorded using ECG devices to track physiological responses.
A z-standardized cross-correlation of synchrony values and regression analysis were performed.
The regression analysis revealed no significant effect of laughter on interpersonal synchrony (R² = .035, F(1, 71) = 2.578, p = .113).

Implication

Examines the effect of laughter on physiological synchrony in preschool children, suggesting new social interaction benefits.
