We investigate how people feel product's impressions using functional near-infrared spectroscopy (fNIRS). We show product's pictures processed in various ways and price to subjects, they decided to purchase or not. Then, we observe their brain activities using fNIRS. Subjects reported their impressions about product's appearance and prices. Product's pictures assign to categories by kinds of process. We classified results in the category. Viewing picture of the category with the trend of low level rating on impression of the product's appearance, the orbitofrontal cortex changed activity. Viewing ones with the trend of one-sided rating, the orbitofrontal cortex changed activity more widely. These findings suggest a possibility that the orbitofrontal cortex changed activity corresponding to impressed level by viewing product's pictures.
