Research in the laboratory focuses on perception, cognition, and action. The main themes include: (1) scientific investigations on explicit and implicit processes in human perception, cognition and action, (2) interdisciplinary approaches to cognitive science, and (3) real-life applications of knowledge of cognitive science. Recent projects include: perceptual distortion of space and time, psychophysical investigation on audio-visual integration, automization process of learned sequential actions, implicit processes for decision making based on preference, cognitive analysis on media contents, eye movement study on visual cognition and attention, implicit learning of visual context, implicit motor synchronization, cognitive neuroscience on interaction between digital media and children, postdictive decision making. We closely collaborate with AIST (Cognition and Action Research Group, HSBE, Japan), ERATO (Shimojo Implicit Brain Function Project, JST, Japan), Caltech (Shimojo lab, USA), National Center for Child Health and Development (Japan).
