Academic disciplines in the humanities, such as psychology, linguistics, economics, and aesthetics, construct models of mental processes based on observations and records of human behavior. When developing such models, it is crucial to understand the impact of affect on human behavior. However, models that directly incorporate affective information have been challenging to construct due to the difficulty of accurately measuring “how an individual feels”.
fMRI is a technique to measure the brain activity of living humans, known to be safe without concerns of radiation exposure. Due to recent advancements in analytical techniques using machine learning, it is now possible to estimate an individual's emotional state by observing their brain activity (Chikazoe et al., 2014; Pham et al., 2021). However, there are many technical difficulties in the analytical processes and few linguistic, economic, and aesthetic models have successfully incorporated affective information estimated from brain activity.
In this research area, Chikazoe (Araya Inc., National Institute for Physiological Sciences), an expert in fMRI research using machine learning, aims to construct a new academic framework that interprets language, economics, and art through the perspective of affect. He is assisted by Professor Daichi Mochihashi (Institute of Statistical Mathematics), who specializes in natural language processing; Professor Yasutora Watanabe (University of Tokyo), an expert in microeconomics; and Professor Tomohiro Ishizu (Kansai University), a specialist in aesthetic research.
