In this study, we developed a chatbot that gives advice for improving well-being and obtained basic knowledge about its well-being improving effect. In the design of the chatbot, we derived advice candidates from behaviors that are highly correlated with well-being based on a questionnaire survey. In the quantitative survey, the chatbot gave advice 172 verification subjects 13 times from the derived advice candidates. As a result, we confirmed that the group that executed a lot of contents of the advice improved the well-being level compared to the group that executed few ones.

A total of 10 highly representative sitcoms from the United States and China were selected, and questions were asked about how the laugh track insertion point (L.I.P) occurred due to the factor of “mixing reality and fiction’’, and what kind of expression between the American and Chinese sitcoms. Clarified if there was a difference. As a result, it was found that there were many points of occurrence of laugh tracks caused by the major category item “mixture of reality and fiction” in China with a significant difference. In terms of small classification items, the United States has a relatively higher ratio of “insertion of real things into topics,” “logic justifying strange obsessions,” and “serious discussion of fiction” compared to China. In China, the ratio of “exaggeration”, “becoming serious after being lied to”, “lieping and making mistakes”, “strange proposal”, and “successful operation” was shown to be relatively high.

This research focuses on picture books, a medium for childhood reading, during which gender stereotypes are formed. The colors of the clothing of characters in picture books and the words they utter reveal characteristics of gender expression. The results showed that gender and age were among the most prominent characteristics in depicting characters in picture books, with red used more frequently for females and less bright shades for males. The proportion of colorful colors was higher among children, and the ratio of achromatic colors increased with age. These results are consistent with previous studies on color images and the evolution of color preferences with age. In the text, it was found that the differences between men and women in the way they perceive things are reflected in the text. These results suggest that picture books may influence the formation of children’s gender images and color preferences.

The correspondence between subjective expression (psychological quantity) and physical information (physical quantity) of the texture of black Roiro lacquer film was examined in relation to the sensitivity evaluation and light reflection characteristics of Roiro finish lacquer film, using Urushi (Asian lacquer), cashew resin paint, and polyurethane resin paint as the coating film and surface polishing used for finishing in the freshly painted finish and black Roiro finish. As a result, in the black Roiro (polished black color) finish, a coating film with low light scattering and a strong sense of blackness was evaluated as “blackness” and “glossiness.” The black lacquer coating film in the Roiro finish is assumed to be an effect of the top-sliding process using Japanese Urushi in the lacquer coating process.

This study evaluated the effect of the sense of unity on the plant on the likeability. To evaluate the effect on the sense of unity, experiment was conducted on the sense of body ownership, sense of agency, psychological distance, and likeability. In the experiment, three conditions were tested: Condition in which experimental participants move but plant do not (No Movement: NM), Condition under which the plant also move in synchronization with the movements of the experiment participants (Synchronous Movement: SM), and Condition that the plant behaves randomly regardless of the behavior of the experimental participant (Random Movement: RM). Participants in the experiment were asked whether they were currently growing plants, and were divided into two groups: those who were growing plants and those who were not. The results of the experiment confirmed that, regardless of whether the plants were cultivated or not, the movement of the plant in sync with the movement of the human body increased the sense of agency, likeability, and brought the participants closer psychologically to the plant. However, the effect on the sense of body ownership was limited.

In this study, as material for discussing vehicle driving comfort at night, analysis was conducted based on the results collected and organized by means of a questionnaire administered to 297 respondents. Specifically, 80% of the respondents felt that nighttime driving was not comfortable, which was the majority of all respondents. There was no difference in the number of respondents who felt nighttime driving was less comfortable than daytime driving according to gender and the number of times they drove, but there were differences according to age and the number of years they had held a driver’s license. The most common reasons for feeling uncomfortable driving at night were “poor visibility,” “glare from oncoming traffic,” and “not enough light”. The effect of LED lighting was found to be significant in scenes where nighttime driving is comfortable.

The quality of communication significantly changes by depending on whether people face each other in a real space. We have developed MR system that people in remote locations exist in the same place virtually. The sense of being together is defined as sense of coexistence as if members of an organization or a community exist in the same place. We hypothesized that this sense of coexistence would be enhanced by the presence of people in remote locations in the same space. In this research we construct a system that places a person in a remote location in the same space virtually and verify how much sense of coexistence can be obtained through MR system. The results for coexistence show that the communication by MR system is close to one by face-to-face and is better than one by Zoom system and MR system is valid among not familiar but unfamiliar people.

The purpose of this study was to examine the effects of environment-conscious information about goods and showcase in commercial environment on forming an intention for environment-conscious behavior. Questionnaire survey was carried out with 60 university students divided the perspectives of customers (in Experiment 1) or store employees (in Experiment 2). The results indicate that participants viewed their purchasing and working behaviors as environmentally conscious behaviors. The presentation of information about environmentally conscious goods and showcase influenced forming a specific intention of environmentally conscious behavior, from both consumer and employee perspectives. Additionally, information about the environmentally conscious of showcase influenced forming a general goal intention of environmentally conscious behavior in both perspectives, as well as a specific intention of environmentally conscious behavior from the employee perspective. However, information about the environmentally conscious of goods didn’t influence forming a specific intention of environmentally conscious behavior from either perspective.

We investigated how audio-visual emotional expressions from humans and robots impact human altruistic behavior. Participants took part in the Dictator Game as “allocators” and allocated money to either a human (Study 1) or a robot (Study 2) acting as the “recipient.” After the first allocation, the recipient responded with emotional expressions of happiness or sadness through body gestures and voice. In the second round, participants allocated money again. The results showed that when the human recipient expressed sadness through body gestures, participants increased their allocation amount, regardless of vocal expressions. However, participants’ altruistic behavior towards robots was not influenced by the robot’s emotional expressions. Instead, they increased their allocation when they perceived the robot’s emotion as sadness, irrespective of the robot’s actual emotional display (happiness or sadness). These findings indicate that human altruistic behavior is present towards both humans and robots, but the triggers for such behavior differ.

Past research has assumed that a one-factor structure can illustrate the Implicit Theory of Intelligence (ITI), however recent studies revealed that rather two-factor structure could account for the ITI. Thus, the present study focused on two-factor structure ITI and examined whether the incremental theory or the entity theory affect more Grit that consists of perseverance and passion for long-term goal dimensions. The survey adopted 162 undergraduate students, who were asked to complete the questionnaire assessing about their items concerning the incremental theory, the entity theory, and Grit. The results of multiple regression analyses demonstrate that the incremental theory significantly relates to the perseverance of effort. These results suggest that the incremental theory would be one of the predictors influencing the perseverance of effort but not the consistency of interest.
