Developmental Construction of Infant's Gaze Alternation as Active Subjectivity
Takeshi Konno, Takashi Hashimoto (JAIST)
Abstract (in Japanese) (See Japanese page) 
(in English) Gaze alternation behavior is thought of as a basis of infant's communication ability. The importance of subjectivity of the gaze alternation is pointed out. Namely, infants understand others' intentions and subjectively gaze at the others' gazing points. In this paper, for understanding the subjective aspect of the behavior, we constructed a computational model with constructive approach. In the model, an agent of infants acquires behavior of gazing at mother's face and objects through reinforcement learning. In the process of acquisition, the agent stores the relations between sensory information while looking mother's face and that while looking objects as a frequency distribution. The sensory information includes three elements:(1) the placement directions of the mother's face and the objects,(2) the mother's eye directions and the object shapes, and (3) the proprioception of the muscle states. Using the distribution, the agent associates sensory information during looking mother's face with that during looking objects. As results of computer simulations, we confirmed that the agent could acquire the behavior of gaze alternation. Furthermore, the agent can gaze at an object beyond sight following the association.
