Outline Activities
Various human natures are based on the characteristics that animals had acquired during long evolutionary processes. However, humans have acquired unique characteristics such as language, esthetic sense, sympathy etc. The purpose of my research is understanding humanity in terms of diversity, genetic bases and neural mechanisms of those characteristics.

Current and Past Project
  • Considerable amount of color vision variation exists in humans due to genetic polymorphisms. Approximately 5% males possess color vision types that show difficulty in discriminating red from green. The difference in color vision would influence attention and might lead to differences in visual preference and/or esthetic sense. In this study, I aim to explore how color vision differences influence attention to visual arts by using eye-tracking technique. I am examining if the genetic differences can be a factor which produces individual differences in visual esthetic sense. By elaborating a methodology which estimates differences of visual attention, preference and esthetic sense, this study would contribute to creating desirable universal visual design.
