Research Interests





I obtained a Ph.D. (Experimental Psychology, 1995) and MS (Experimental Psychology, 1989) both from the University of Tokyo, Japan. I worked in ATR Human Information Processing Research Laboratories in Kyoto from 1992 to 96 as a Research Associate. Since 1996, I have been working as a leader of Computational Psychology Group in KDB, ERATO, JST.

Research Interests

My original research interest is in human sensorimotor learning from psychological and computational points of view. Using methods of experimental psychology, I have been studied generalization abilities of skills and coordinate systems adopted by the sensorimotor integration mechanism. I have started investigating brain activation using fMRI (functional magnetic resonance imaging) when human subjects are learning skills to use a new tool.
