We propose a system to prevent identification of an individual identity by changing the size and position of one's facial regions. Invasion of privacy and the right of publicity have been a problem along with the popularization of social media and improvement of image resolution. The mosaic and the blur have been used to prevent identification of a person's identity. These techniques, however, make people difficult to understand the context of the video, because the facial expressions of the characters and the background in the video are masked. In this paper, we focus on naturally conversing the facial appearance in images for protecting their privacy. We examined the proper degree of facial changing parameters, and performed user studies to evaluate these parameters.

The human primary somatosensory cortex corresponds to an organized topological map of all body parts (somatotopy). However, the representative proportion of body parts in the brain differs from that of the physical body. This distorted representation is called the cortical homunculus. Body parts with extensive cortical representation have a greater sensitivity in spatial resolution. We have developed the software, Face Homunculus Viewer, that can modify any facial images to homunculus-like faces with sensitivity parameters. The software was employed to support children and adults in understanding the cortical homunculus and the sensitivity differences of various body parts. Several workshops were held in which participants measured two-point discrimination thresholds at the forearm, lip and forehead to create a personalized homunculus. The software may contribute to user knowledge on the mechanisms of somatosensory perception in the brain of humans through their own embodied experience.

This study examined an acquisition process of “critical thinking disposition” with a four-wave panel data on junior high school students. More specifically, we examined the causal relationships among “critical thinking disposition”, “the skill of practical use of information”, “motivation”, and “communication activity”. We tested several causal models by structural equation modeling, and selected appropriate models. Results showed that “motivation” had effected on “critical thinking disposition” via “the skill of practical use of information”. Also, we found that “truth seeking disposition” which is a factor of “critical thinking disposition” had direct and indirect effected on the other factors of “critical thinking disposition”. Furthermore, we found that “critical thinking disposition” had positive effects on “communication activity”. We concluded that as a way to develop students’ critical thinking disposition, several approach will needed by improving students’ learning motivation, informat on literacy, and truth seeking disposition.

In science education, it is crucial to create teaching materials that are directly linked to students' individual experiences. On “The Japanese Psychonomic Society Committee for Developing Teaching Materials for High School Students,” using computer graphics technology, we developed a visualization system called “Face Homunculus Viewer” (FHV) that provides an opportunity for students to gain a deeper understanding of the relationship between brains and minds. Additionally, we conducted a workshop on human touch perception using FHV. In the workshop, we defined the two-point discrimination threshold of touch as “tactile acuity,” and students measured their tactile acuity with the methods used in psychological experiments. Our contributions are the development of an interactive system for visualizing differences in tactile acuities between bodily sites within each individual and differences between individuals. We believe that this study will indicate a new direction in science education in which computer graphics can be applied.

<p>In this article, we introduce science outreach activities of a committee in the Japanese Psychonomic Society. The committee named as "The JPS committee for developing teaching materials for high school students" started in 2012, aiming at developing interactive teaching materials and media workshops (MWS) for science education, specifically for education of the "brain and mind." The committee members consist of the researchers of various fields, such as cognitive psychology, engineering education, interaction design, virtual reality and media arts. Media technologies enable us to create teaching materials that are directly linked to the students' experiences. Specifically, using computer graphics technologies, we developed a visualization system called "Face Homunculus Viewer (FHV)" and a face image transformation system called "Accidental Resemblance Generator (ARG)." The usage of the systems in the MWS can provide opportunities for students to gain deeper understanding of their brain and mind, and to learn the methods used in psychological experiments. The committee provided FHV application and documented procedures of the MWS for public, in order to broaden the user of the application, such as teachers at schools and science communicators at science museums. The MWS of ARG was also used for the validity evaluation of face image transformation method. For further development of the MWS we are planning to hold an "ideathon" (idea marathon) of concepts of new teaching materials.</p>
