Does time feel longer or shorter to you than it feels to others?
Perceptual research brings unexpected discoveries

↑ (Research on the asynchronous processing of color and motion information)

My research team studies study sensation and perception. For instance, in a class, the students are likely to feel that an hour drags on, whereas the lecturer will tend to feel the same hour rush by. Based on various experiments, we strive to clarify the mechanisms of such perceptual wonders relating to time, velocity and locomotion, as well as how the brain processes information gathered by the eyes and ears.

We’re often disappointed to see experimental data that apparently reveal randomness arising from the extremely complex nature of human beings. However, after repeated analyses from multiple perspectives, unexpected universal laws begin to come into view, to our profound satisfaction. Since the study of perception is still full of wonders and the unknown, it’s no pipe dream for you to become the discoverer of some new law.

  • Through perceptual research on time, vision and attention, we’re currently exploring the borders between overlapping studies. (Photo: Books with multiple authors or translators)

Research themes lie within yourself:
Knowing what you want to know is the starting point.

My basic educational policy comes from the idea of a “tabula rasa”. In other words, the starting point is what the students themselves—blank slates—develop an interest in. Perceptual studies are conducted based on more than just subjective judgments such as “I feel this so” in some vague way. They’re conducted based on more scientific thinking. Researchers are required to think independently. What matters most is to know what you want to know or to find a research theme you want to elucidate. Once you determine the theme you want to address, then the necessary experimental methods will follow naturally.
