Not only facial expression and gesture, but contagious yawning is also known as a representative example. Previous studies suggested that the frequency of contagious yawning is rare in autism spectrum disorder, while contagious yawning between in-group is more frequent than out-group. Thus, there would be robust relation between contagious yawning and empathy. However, it is not clear that the sequence of empathic function when we observe the other's yawning motion. Present study investigates the temporal sequence of brain activities observing other's yawning motion with event-related brain potentials (ERP). In addition, we use standardized low-resolution brain electromagnetic tomography (sLORETA) to investigate the spatial dynamics for observation of yawning. As a result, when we observed the yawn, although the inhibition function of reaction was activated, the mirror neuron system (cognitive contagion) would be automatically elicited, then affective contagion (i.e., empathy) was induced, from the evidences of event-related potential. The presented study suggested that the cognitive contagion and the affective contagion were qualitatively different with each other, because they were processed by different brain areas with different temporal dynamics. We demonstrated a temporal dynamics of cognitive/affective empathy as well as spatial dynamics., 信学技報 IEICE Technical Report HCS2013−7,HIP2013−7(2013−05)}, pages = {37--41}, title = {あくびの伝染に関する認知的・情動的共感機能の時間的遷移 : 事象関連電位を用いた検討}, volume = {113}, year = {2013} }
