Research<\/h2>\r\n

\r\nHuman infants acquire diverse cognitive functions within the first few years of life. Although the dynamics of cognitive development have been increasingly analyzed, the underlying neural mechanisms are still not fully understood. We aim to clarify these mechanisms from a constructive perspective based on the embodied predictive processing theory, which extends general principles of brain function. Predictive processing is a framework in which internal models are updated and actions are generated to minimize prediction errors\u2014the differences between bottom-up sensory inputs and top-down predictions. By incorporating embodiment into this framework, we explore how not only brain refinement but also sensorimotor development and social interaction influence cognition. We implement neural network models grounded in this theory into robots and allow them to learn from varied sensorimotor experiences to examine how and to what extent developmental continuity and diversity can be accounted for. The findings are further applied to assistive technologies for individuals with developmental disorders, aiming to promote self-understanding and support the design of an inclusive society.\r\n <\/p>\r\n <\/div>\r\n

Biography<\/h2>\r\n

\r\nYukie Nagai received her Ph.D. in Engineering from Osaka University in 2004. Following her doctoral studies, she held research positions at the National Institute of Information and Communications Technology, Bielefeld University, and Osaka University. Since 2019, she has served as a Project Professor at the International Research Center for Neurointelligence (IRCN) at the University of Tokyo, where she leads the Cognitive Developmental Robotics Laboratory. Her research explores the developmental mechanisms of human social cognition through computational approaches.\r\nIn recognition of her contributions, she was selected as one of the Analytics Insight \u201cWorld\u2019s 50 Most Renowned Women in Robotics\u201d in 2020, one of the IEEE IROS \u201c35 Women in Robotics Engineering and Science\u201d in 2022, one of the Forbes JAPAN \u201cWomen In Tech 30\u201d, among other honors. She is also the principal investigator of two JST CREST projects: \u201cCognitive Mirroring\u201d since 2016 and \u201cCognitive Feeling\u201d since 2021. Her concurrent roles include Project Professor at both the Next Generation Artificial Intelligence Research Center and the Center for Coproduction of Inclusion, Diversity, and Equity at the University of Tokyo; Visiting Professor at the Center for Human Nature, Artificial Intelligence, and Neuroscience at Hokkaido University; and Associate Member of the Science Council of Japan.\r\n<\/p>\r\n <\/div>\r\n\r\n
