Although contagious yawning occurs commonly in adulthood, previous studies reported it to be uncommon in children below 4-5 years. However, these studies did not regulate eye contact, a factor that can induce contagious yawning. We therefore investigated whether a cue to make eye contact would influence contagious yawning, particularly in young children. Fifty-six children between the ages of 3 and 16 watched video clips of models either yawning or opening their mouths. Contagious yawning was observed from the age of 3 years, and was negatively correlated with age. Whereas children older than 8 years caught yawns only after the yawning clips, children under the age of 8 years yawned contagiously following both yawn and control clips. Additionally, frequent imitation occurred in children below the age of 8 years. Poor general attention skills or reduced attention to specific facial features (e.g. the eyes) may be responsible for the reduced yawn contagion previously described in young children.
