Hiroshi Imamizu, Ph.D.
Computational Psychology Group
Kawato Dynamic Brain Project, ERATO, JST
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.
