Cognitive Development Based on Sensorimotor Predictive Learning

Human infants acquire various cognitive abilities in the first few years of life. Although behavioral changes in infants have been closely investigated, the underlying mechanisms for the development are not yet completely understood. We proposed a theory of cognitive development based on predictive learning of sensorimotor information. Our robot experiments demonstrated that various cognitive functions such as self-other cognition, imitation, […]

Simulator of Atypical Perception in Autism Spectrum Disorder

Individuals with autism spectrum disorder (ASD) suffer from hyperesthesia/hypoesthesia as well as difficulties in social interaction. To understand the underlying mechanism for atypical perception and its influence on social de cits, we computationally analyzed the process of how atypical perception is elicited in social contexts. Our experiment employed visual and audio processing techniques to let ASD participants reproduce their experiences, and […]

Predictive Coding Account for Developmental Disorders

Developmental disorders such as autism spectrum disorder have been characterized by deficits in social interaction. Recent studies in cognitive neuroscience and Tojisha-kenkyu, however, suggest that atypical processing of sensorimotor signals might be their crucial difficulty and cause deficits in higher cognitive capabilities as a consequence. We aim at understanding the underlying mechanism of developmental disorders by means of computational approach […]

Motionese: Exaggerated Action for Infants and Robots

Developmental studies have suggested that human caregivers significantly modify their actions when interacting with an infant compared to with an adult. Such modification called motionese is characterised by higher roundness of movement, longer and more pauses between actions, and closer distance to the infant. However, the underlying mechanisms of motionese and influences of motionese on infant action development are uncovered […]

Development of Joint Attention

Joint attention is a process to look at the object that someone is looking at. Previous studies in developmental psychology have suggested that the ability to achieve joint attention is acquired between 6 and 18 months old and that it plays an important role in infants’ further cognitive development. We investigate what inherent mechanisms enable infants to acquire the ability, […]

CREST Cognitive Mirroring

JST CREST “Cognitive Mirroring: Assisting people with developmental disorders by means of self-understanding and social sharing of cognitive processes” (Research Director: Yukie Nagai, Period: 2016.12-2022.03) This project aims at developing cognitive mirroring systems that make human cognitive processes observable. We hypothesize that predictive coding in the human brain plays a crucial role in cognition and intend to better understand its […]

KAKEN Constructive Developmental Science (Scientific Research on Innovative Areas)

Grant-in-Aid for Scientific Research on Innovative Areas “Constructive Developmental Science: Revealing the Principles of Development from Fetal Period and Systematic Understanding of Developmental Disorders” (Project Leader: Yasuo Kuniyoshi, Period: 2012.06-2017.03) How does human mind develop? What causes developmental disorders? Recent studies suggest the importance of the fetal period in human development. However, study of human fetuses is strongly constrained by […]

KAKEN Constructive Developmental Science (Specially Promoted Research)

Grant-in-Aid for Specially Promoted Research “Constructive Developmental Science Based on Understanding the Process from Neuro-Dynamics to Social Interaction” (Project Leader: Minoru Asada, Period: 2012.05-2017.03) How the microscopic neural activity is reflected in the human behaviors is a big mystery shared by many different disciplines. Medical and neuroscience have tried to explain the microscopic structure inside the brain but have not […]
