In the research subfield 'C01', the underlying mechanism of neuronal dynamics on communications is elucidated by investigating the strategy for communication between humans, humans and non-human primates, humans and robots, or humans and the environment.

| Clarification of mechanisms for getting information by interactions with others | ||||
| OBJECT | ||||
| This study aims at testing an assumption that interaction with others facilitates obtaining information of new knowledge or technics with a combination of behavioral, neuropsychological, neurophysiological and brain imaging studies in human and nonhuman primates. This assumption is based on the idea that abilities for understanding behaviors or establishing a framework for recognition or physical consciousness of self-other by imitating behaviors of others are important as the basis for communication. The primary purpose is to elucidate how different children with autism are from normal children in understanding behaviors, observational learning and imitation. The secondary purpose is to clarify differences in understanding behaviors, observational learning and imitation between human and nonhuman primates by comparative studies. These comparative studies will elucidate why human communication has dramatically evolved and what are human-specific abilities. We can make a proposal for better educational environment and contribute to well-being of children by elucidating effects of interactions with others in the process of obtaining novel knowledge, technics and concepts in humans. Moreover, elucidating mechanisms for learning relationships between self and others leads to proposals for methods of training for and approach to children with disabilities of understanding mind of others such as autistic children. | ||||

| Study on automonous role taking mechanism of human in social situation | ||||
| OBJECT | ||||
| In this study, we model a human-human interaction as a process that apply action decision process of self to other person, estimate an intention or purpose of the person that is difficult to observe directly and decide action of self based on the estimation. But in general, the process is dynamic. We must quickly respond to a change of other’s intention. We can’t explain the ability of quick responding by known behavior learning model based on trial and error. In this study, we try to explain a rapid emergence of role taking based on the intention estimation of other and on the self action decision using a functional parts combination model of brain (FPC model). In FPC model, we consider plenty of brain cortical and sub-cortical areas as a set of functional parts that can be combined to realize an information processing required for solving a task of a moment.
In this study, we try feasibility study of FPC model for the human-human interaction and construction of a computational theory for social situation.

| Study on a mechanism of meaning creation through interaction between linguistic inference and continuous dynamics | ||||
| OBJECT | ||||
| Communication is considered to be a dynamic process consisting of creation of novel expressions, and sense-making of the expressions through body-environment interactions. We develop system theoretical understanding of the mechanism underlying such dynamic and creative process of communication based on the following three elements:
A Modeling: We construct a mathematical model of the dynamic process of communication as a hetero-system of linguistic inferences and continuous dynamics. By analyzing this system, we study conditions, processes and mechanisms enabling the creation of novel expressions and meanings. B Experiments: We construct an experimental paradigm demonstrating the fundamental dynamics of communication. Through conducting these experiments, we study characteristics of the dynamic processing of meanings and expressions in order to define conditions necessary for communicative interactions.. C Theory: We formulate a model of a hierarchical hetero-complex-system consisting of combinatorial infinity and continuous infinity, by abstraction of the model studied in element A. We analyze this new model to develop system theoretical understanding about the creation of new expressions, meanings and structures. |

| An integrative study on brain mechanism of realtime motor command generation throurgh interaction between the body, environment and neural modules | ||||
| OBJECT | ||||
| The present project aims for revealing the mechanism that our brain generates appropriate motor commands in a real-time manner through interaction with the external enviroment, and for examining the meta-mechanism which generates such motor control structure through self-organization. The fundamental hypothesis is that the temporal consistency between the mechanical dynamics of body/environment and computational dynamics of neural system is essential for real-time motor command generation. Goals of the project include 1) to establish the principle of "intermittent control" which divides the continuous motor task (or temporal axis) into discrete sub-tasks (or short time periods) and executes sub-tasks for individual time periods by feedforward control strategy, 2) to examine the validity of this principle by simulated experiments, behavioral experiments and electro-physiolical experiments (human and animal), and 3) to consider the meta-process where the intermittent control structure emerges by self-organization. | ||||
