Rituals are fundamental social acts that structure relationships and enable the filtering of important cognitive attributes (e.g. working memory and inhibitory control) that make humans what they are today. This study investigated the influence of model age and familiarity on the reproduction of ritual behaviour in five-year-old children. Through an exploration of these factors, this study sheds light on the cognitive mechanisms children use to comprehend and replicate rituals. Ninety-eight five-year-old children were divided into two groups: an experimental group, which observed an adult or child model, either familiar or unfamiliar to them, demonstrating eight ritual acts; and a control group, which received no video demonstration. The results revealed that children who observed an adult reproduced more ritual acts than those who observed a child, and children who observed unfamiliar models reproduced ritual acts more frequently than those who observed familiar ones. Additionally, when exposed to unfamiliar models, children's reproductive fidelity was higher. These findings suggest that children have the ability to address new adaptation challenges by participating in rituals at an early age and that they generate suitable solutions depending on the model's characteristics. This provides evidence for the adaptive bias in children's cultural learning from a ritual perspective.
