Influence on brain waves of appreciating a picture

Changes of emotion in viewing a picture were measured by brain waves with an emotion identification system. Picture No.1 was by Dali, No.2 by Lautrec, and No. 3 by Sam Francis. Two subjects viewed each picture for 5 minutes. Subject’s brain waves viewed were evaluated based on four emotion indexes (relaxation, sadness, joy and anger). The two subjects showed a strong pattern of anger to all three pictures. The pictures used for this study represented highly individualized styles of painting. Therefore, they were considered to have possibly evoked strong feelings.
