Outline of Final Research Achievements

We used near-infrared spectroscopy　(NIRS) to measure hemodynamic responses while the participants viewed　photographs of self-face and stranger-face. In the AN group, activity of the brain significantly increased in the right temporal area during the presentation of both the self-face and stranger-face images compared with the baseline level. In contrast, in the control group, the activation significantly increased in the right temporal area only during the presentation of the self-face image. And we also investigated the brain activation in ADHD children who observed smiling and anger facial expressions of emotions using NIRS. ADHD children showed an increased activation for happy faces but not for angry faces, while TD children showed increased activation for both faces. Finally we also studied perceptual development of surface material perception using preferential looking method and categorical color perception using NIRS.
