High school students' impressions of behaviors of child-like robots that can be trained to take intelligence tests

Abstract

In recent years, the demand for clinical psychologists has increased as the proportion of developmentally disabled children in mainstream classes has increased. Training in the administration of intelligence tests is provided through demonstrations with children. However, clinical psychologists cannot provide sufficient training because it is difficult to find subjects for training. In this study, we develop a child-like robot (proposed robot) that receives intelligence tests from clinical psychologists. The proposed robot is equipped with speech and behavior similar to that of a child undergoing intelligence testing. In this paper, we investigate whether the proposed robot's speech and movements are like those of the child being tested. In particular, the size of the robot has a strong influence on the child’s behavior. For this reason, comparative experiments with two types of robots of different sizes were conducted with high school students, who are younger than clinical psychologists. The results showed that the robot with the smaller body made a more childlike impression on the intelligence test than the robot with the larger body.
