Women’s Softball × Sports Brain Science▼Abstract

In the world of sports, the key to success is often the ability to make snap decisions and act instinctivelyfaster than making conscious decisions. The Kashino Diverse Brain Research Laboratory at NTT
Communication Science Laboratories is researching the implicit brain functions that are exhibited byathletes under these special conditions. Together with the Japan women’s national softball team, which won
the gold medal at the 2021 international sporting event held in Tokyo, NTT has been working on practical
initiatives in parallel with academic research to apply the findings of this research to improving the team’s
chances of winning.
