Here we investigate the extent of children’s understanding of the joint commitments inherent in joint activities. Here we investigate the extent of children’s understanding of the joint commitments inherent in joint activities. Afterwards, children who had made the joint commitment were more likely to stop and wait
for their partner on their way to fetch something, more likely to spontaneously help their partner when needed, and more
likely to take over their partner’s role when necessary. There was no clear difference in children’s tendency to tattle on their
partner’s cheating behavior or their tendency to distribute rewards equally at the end. It thus appears that by 3 years of age
making a joint commitment to act together with others is beginning to engender in children a ‘‘we’’-intentionality which
holds across at least most of the process of the joint activity until the shared goal is achieved, and which withstands at least
some of the perturbations to the joint activity children experience.
