Cognitive Psychophysiology Laboratory (CPL) was first established at Hiroshima University on April 2005 and has moved to Osaka University since April 2016.
Our primary interest is to deepen the understanding of daily psychological activities by using event-related potentials (ERPs) and other psychophysiological measures.
Recently, we have started to explain kawaii (often translated as “cute”) from a behavioral science perspective.
