Research

Associate Professor at the College of Comprehensive Psychology, Ritsumeikan University. I examine how psychology shapes and is received by society—and how society in turn shapes psychology—revisiting its history to consider its future. My work also covers law and psychology (interrogation, the lay-judge system) and the use of AI in qualitative research.

History of psychology and its relation to society

I critically examine how psychology has changed over time—through the lenses of social and academic institutions and of science and technology. By tracing how psychology shapes society, how it is received, and how it is in turn shaped by society, I revisit its past to consider the future of the discipline.

Law and psychology

I study the criminal justice system from a legal-psychological perspective: how the way recorded interrogations are presented affects judgments of confession voluntariness, how a defendant's attributes influence lay judges' sentencing, and how people make decisions in cooperation-type plea bargaining.

AI in qualitative research

Asking whether AI can be incorporated into qualitative research, I conduct qualitative studies using large language models (LLMs) and other AI technologies, examining their significance and limitations through comparison with human analysis.

Cultural and social psychology

I investigate how culture and social context shape human cognition, judgment, and behavior, drawing on social and cultural psychology.
