| Research Abstract |
We investigated the brain activities that are associated with abstract faces by using functional MRI (fMRI). The experimental results showed that the right inferior frontal gyrus was activated with emoticons, graphic emoticons and photorealistic faces. It is possible that the activation of the right inferior frontal gyrus is related to nonverbal communication. The middle temporal gyrus was activated with caricatures and graphic emoticons. We may perceive graphic emoticons and caricatures as dynamic and living agents. It is believed that caricatures and graphics emoticons play an important role in enriching communication among users.
