Outline Activities
Underlying the diversity of color perception in humans are unique neural representations formed by interaction between genetics and environmental stimuli. Specifically, my research aims to understand how humans with various color vision types share color categories by means of language in spite of the diverse perception of colors.
Research Interests
  • Color vision diversity
    keyword : color vision, diversity, gene, neural mechanism
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.
  • The international research group designed experiments to explore the function, evolution, and diversity of color vision in primates.
