There has been growing interest in social robots for the past ten years, especially in the context of their assistive contribution to the diagnosis and rehabilitation of certain specific disabilities. Numerous studies have confirmed that robots are a good tool for learning social, communication, motor and other skills because they provide the experience of social characteristics that are present in human interactions, but they are also objects that can be manipulated. However, most of research has been conducted on the population of children with autism spectrum disorder, and there isn’t many data about how typically developing children react to robot and his actions. In addition, it has not been systematically investigated whether, and in which extent, do reactions of children to the actions of humanoid robot differ from reactions to the same actions performed by human. The purpose of this study was to construct a protocol for testing the reactions of children to the humanoid robot and to use it to examine whether children prefer robots or visually similar object, and do they focus more attention on a person or humanoid robot when interacting. The study included three tasks and was conducted on the sample of 14 typically developing preschool children. According to the results, participants did not pay more attention to the robot in comparison to the object. Furthermore, the participants did not spontaneously imitate dance and greeting gesture performed by humanoid robot, and did not behave in a way that would suggest that they perceive humanoid robot as a person. However, it has been confirmed that participants directed more attention to the humanoid robot while observing communication between humanoid robot and human being. Finally, it has also been observed that the participants shared their experience and enjoyment of the robot's dance with the adult companion. Despite the fact that generalization of results is not possible, due to the small, heterogeneous sample, further extensive trials, which will seek to minimize the technological shortcomings and omissions in the protocol, could yield significant information.
