This paper describes linguistic features of generally unreadable person names, which are defined as “KIRAKIRA names,” and proposes a method to detect KIRAKIRA names based on the features. Through the discussions, the following eight features are founded as the linguistic features of KIRAKIRA names: 1) Too many Kanji characters, 2) Too many syllables, 3) Multiple usage of a common Kanji character, 4) Kanji variants are used, 5) The pronunciation of Kanji is generally unknown, 6) Too many stroke count for Kanji, 7) Mismatching of gender between a person and the name, and 8) The pronunciation of name equals an imported word. Based on the features, KIRAKIRA names are automatically detected by using Support Vector Machine. The experiments to detect KIRAKIRA names were conducted for 10,000 names. The results of the experiments showed 81.79% accuracy, 76.89% precision, and 91.84% recall.

Plastic surgeons create of external noses based on their kansei. The outcome of the rhinoplasty depends on the surgeons' technique and artistic sense. We consider that reconstructing an external nose by using a template would solve the inconsistency of the outcome. However, there are few studies about curves of outlines of external noses. Thus, the aims of our study were to analyze curves of outlines of external noses of 84 normal subjects and to classify the curves in order to create templates as a guide for total nasal reconstruction. Concretely, we took photographs of 84 subjects' external noses and abstracted the curves of their profile outlines of external noses from the photographs by image processing. Next, we analyzed characteristics of the curves by using those profiles of curvature and classified the curves into 5 types of curves. Lastly we made innovative 380 (= 5 types × 76 sizes) nose templates based on our study in order to express the individual subtle differences of the reconstructed new nose.

In order to increase the number of videos playback, we researched on the thumbnail images and the titles which were selected by the viewers. We built the samples and conducted the questionnaires in order to reveal the factors that make a great influence on the evaluation and be clear about the positive levels. We revealed the viewers decide the videos under the influence of the images rather than sentences and words. Also, Images factors are particularly effective for males. On the other hand, females are more affected by sentences and words than males. This research revealed the guidelines that YouTuber creates thumbnail images and titles and the elements to incorporate according to the target the males or the females. As a starting point of this research, we will be able to conduct more detailed research on thumbnail images and titles.

This paper is aimed at evaluating the effect of prolonged mental stress on human physiological state. The human secretory immune and endocrine substances were introduced as “biomarkers” of such a prolonged stress. This relatively new field of study investigating the relationship and/or interaction between human mental and somatic states has been developed according to the development of the molecular analysis techniques, such as Enzyme-linked immunosorbent assay (ELISA), and showed that the several secretory hormones and immune substances could possibly be useful stress markers. However, what types of stressors and its duration could be evaluated by such biomarkers is not well understood. In this article, the effect of prolonged mental stress during long-term graduation examination of undergraduate students was investigated comparing with the effect of short-term mental stress by simple arithmetic task. As a result, one immune substance within saliva, immunoglobulin A, was showed as a possible stress marker for both long- and short-term stressors.

We investigated the acoustical characteristic of the sounds of crickets and its physiological and psychological effect on Japanese people. The sounds of crickets belonging to Family Grylloidae were grouped into 3 clusters by using the acoustical characteristics of the sounds. For this study, 3 Grylloidae species and 2 Tettigoniidae species were selected, and the sounds were recorded in a dark room. The psychological effect, i.e., pleasantness, was investigated by administering a questionnaire, which was based on the Semantic differential (SD) method. The comfort provided by the sounds was estimated on the basis of the findings on electroencephalograms in terms of an increase in the alpha wave. From the results of the questionnaire, people preferred the sound of crickets belonging to Family Grylloidae, rather than to those of crickets belonging to Family Tettigoniidae. It seemed that there was a deep relationship between the generation of alpha wave and the duration of the silent time within the sequential sounds. On the other hand, the rate of alpha wave increase in each species was not in good agreement with the results of the questionnaire, suggesting that further study is requires to understand the relationships between psychological and physiological effect on the human's Kansei. Finally, we proposed the effective presentation of the pleasant cricket sounds.

In this study, we investigated the relation between autism spectrum tendencies of normal observers and evaluation of facial emotional expressions, used for “Ban Dainagon Emaki”. Recognition of facial expressions was verified by Scheffé’s (Nakaya) paired comparison method using the evaluation attributes of the four emotions (fear, anger, sadness, and happiness) in conjunction with investigation of the Autism-Spectrum Quotient (AQ). Different cognitive patterns especially extracted from communication ability, were confirmed, comparing facial expression recognition tendencies for the two groups, higher levels of autistic - like traits and lower levels of autistic - like traits. Between the two groups, the high levels on the AQ were difficult to recognize the fear of negative emotions, but regarding the happiness of positive emotion, similar tendency was demonstrated. These results are consistent with the findings obtained from previous studies on the tendency of facial expression recognition between healthy individuals and those with traits of ASD.

Interest in pet robots and virtual pets is currently increasing along with the pet boom. Pet robots and virtual pets have been found to be therapeutic. However, what characteristics of pet robots and virtual pets are therapeutically effective have yet to be clarified. In this study, we carried out experiments to compare the therapeutic effects between pet robots and virtual pets in terms of physical embodiment from psychological and physiological aspects. Psychological evaluation results showed that the reduction in the tension score and increase in the vigor score with pet robots were significantly higher than those with virtual pets. Physiological evaluation results showed that the increase in the percentage of alpha waves with pet robots was significantly higher than that with virtual pets. These results suggest that physical interaction is an element for reducing mental strain and improving vitality.

We discussed how people behave on seeing kawaii animal toys. Many studies have indicated the effects of kawaii emotions. However, few have described how they are expressed behaviorally. Therefore, this paper reports observable behavioral indicators. Specifically, we observed 4 human behaviors: smiling, touching, talking, and watching (kawaii toys or people) - during conversations when they see animal toys. Participants were divided into two groups. One (kawaii group) selected the animal toys that they felt had the most kawaii, and another (non-kawaii group) selected the animal toys that they felt had the least kawaii. Time to behavior was measured by annotation software, analyzed by analysis of variance. Comparison of groups showed that kawaii group was smiling, talking, and watching people for a longer time. Conversely, non-kawaii group was watching animal toys for a longer time. These results deepened our understanding of human behavior caused by kawaii emotion.

Modern life overflows with the maturity of industrialized society. The ideal way of the consumer who makes [Yarikuri] is long lost. Now the theme of ecology is important. It is thought that we should review the lost custom, and improve the way we consume. Kimono, if it is seen from the point of “Let us not waste! [Mottainai] value”, has an excellent characteristic in recycling and reuse. The system that uses it well exists. Kimono returns to one cloth when the seams are removed. It was a merchant named Shikkai to have handled the system. The industrialization society put it at maturity then, I researched who Shikkai are in what situation and what role he plays. As a result, it is exposed to the crisis of the disappearance with the decline of the kimono culture though Shikkai has undergone a transfiguration with the transition of economy and industry of our country after the war. However, the idea and aspect of “Let us not waste! [Mottainai] value” run to the basic concept [Kurimawashi] of Shikkai, and peeling off and using the original value of kimono. In addition, it is thought that it is necessary to study the behavior patterns of the coordination of collecting knowledge over many topics and using it.

To create innovative ideas, it is important for designers to monitor thought patterns by reflecting upon their thought structure and then control thought. In this study, we visualized the inference process, which includes deduction, induction, and abduction, as well as the associative process. Subsequently, by connecting them radially along the flow of thought, we employed a method of visualizing the inference process of designers on a two-dimensional plane. We conducted an experiment to visualize a part of the thought of designer using the “inference mapping method.” Consequently, we found out that different cognitive biases occurred in designers' deductive, inductive, abductive, and associative thinking processes. From the technical viewpoint of cognitive science, we studied the phenomena and clarified the structure of bias in each thought process. Finally, we proposed a way to visualize cognitive biases and to consciously eliminate them when designers engage in the creative process.

This paper proposes a new approach for the analysis of a customer's initial impressions of an automobile front view. It is important for manufactures to analyze the differences in the expression that a studied automobile provokes in the viewer. We have tried to estimate quantitatively both the “facial expression” and the “perceived age” using modals that are already in common usage, for fifty automobile front views. Two visual stimuli were used in our experiments: the drawings and the caricatures generated by an automotive caricaturing system coche-PICASSO. The results show that this approach is effective in analyzing motor vehicle viewer perception.

Oshibori is a small wet towel to wipe hands before meal in Japan. Most of researches on oshibori have investigated the towels from the perspective of cleaning and sanitation. Few studies have assessed the qualitative and sensory characteristics associated with oshibori. In this paper, subjective evaluation experiments were carried out using cotton oshibori of different temperatures such as 5, 15, 30, 45, 60, and 75 °C in the laboratory temperature at 20, 25 and 30 °C over four seasons. 29 males and 33 females evaluated oshibori on following properties such as “favorite,” “rare,” “hot,” “feel-smooth,” “high-grade,” “comfortable,” “soft,” and “moist,” according to five point grading. As results, the oshibori at the temperature of 5, 15, 45 and 60 °C were evaluated to be comfortable. Contrary, those of 30 and 75 °C were evaluated uncomfortable. Moreover, sexual specificity of the evaluation was observed.

Color has long been considered important by both the manufacturing industry and academia because it affects people’s perceptions, emotions, and behaviors. However, the evaluation of purchasing behavior until now has mainly been only in an experimental environment, and there have been concerns that differed from the actual consumer behavior. Therefore, the causal effect of the strong impression of a manufacturer’s brand color on the purchase behavior in the Japanese automobile industry was verified. Covariate was homogenized by propensity score matching based on the online survey, and the causal effect on purchase intention was extracted. As a result, the impression of the brand color had a positive effect on the purchase intention. This effect was estimated to be 5.739 in odds ratio. Commercial brands, logos, emblems, car body colors, dealers, showrooms, and even professional baseball teams were found to be factors that foster brand color.

A person who is struck by deep grief due to the loss of, or unwanted separation from, his/her family, spouse or the one he/she loves is believed to take a long and gradual recovery process from the state of severe mental suffering. This study conducted interviews on ten people who went through such experience to find out how their painful loss or separation took place, their psychological states, their actions in the process of recovery afterwards, the psychological change brought about by such actions, etc. The result found that the activities recognized by the sufferers as effective in facilitating the recovery process included “creative activities, such as painting, crafting, writing, etc.” along with “social activities, such as works and volunteering”, “communications with close friends and relatives”, etc. The creative activities referred here are voluntary ones and exclude “art therapy” implemented as a part of psychotherapy.

Robot-assisted therapy has gained attention as one of mental health measures. In this paper, we investigated the influences of soft tactility on psychological and physiological stress relief effects to verify whether soft robots or hard robots are effective as therapy robots. Resultantly, we confirmed that psychological stress relief effects obtained by interaction with soft robots are significantly higher than that with hard robots, particularly reducing tension and depression, improving vigor. And we also verified that physiological stress relief effects, especially increasing alpha waves, obtained by interaction with soft robots are significantly higher, too. In addition, we found that soft tactility may have effects of inhibiting reduction users' motivation for interaction. These results suggest that soft robots are more effective as therapy robots.

Classification of fragrances has not accepted widely, because the range of stimuli was very wide and words of evaluation were a little. This study picked up essential oils, and selected words from prior questionnaire. Purpose of this study was to classify fragrances by psychological method. This study consisted of 2 experiments, A and B. The same materials and procedures were used in both experiments. Subjects were asked to evaluate fragrances by SD(semantic differential) method. In experiment A, a total of 220 subjects were joined and 15 pair words were used. In experiment B, 75 subjects were joined and 18 pair words were used. Cluster analysis and Factor analysis were used for analyzing the data. As a result, in both experiments, 11 clusters and 3 factors were observed, and clusters of citrus fragrances were showed. The factor of “Pleasantness” was showed in the first factor. This factor was common both experiments.

This paper describes the relationship between voice quality of singing voice and color. We conducted 2 experiments. As stimuli, 28 voices were recorded from 11 amateur female singers. First, matching between voice quality and color was made with paired comparison. Color stimuli were categorized by 3 conditions and selected from the PCCS color system. As a result of binomial test, raters tended to agree with each other in the lightness condition. Second, voice stimuli were evaluated with 13 pairs of word as psychological features and 3 factors were extracted by factor analysis. In addition, 10 acoustic features were calculated as physical features. Based on the result of correlation analysis, it turned out that many features of colors are associated with impressions like a factor of “activity”. We also found that spectral centroid and spectral tilt might be related to some of the color features in the analysis of physical features.

Recently, value-sharing consumption and participation behaviors triggered by words and images transmitted by celebrities, bloggers, and friends are attracting attention. The focus of this research is to clarify the various processes involved in sharing these values, and to contribute to the business management of an industry that relies heavily on sense and emotion. First, I define the idea of value-sharing, then I outline three hypotheses of the processes involved in sharing these values, followed by establishing my hypothesis model. In order to test these hypotheses, I conducted a survey targeted to influencers and event attendees, and conducted a psychological experiment about memory infiltration. The hypotheses were partially supported, however the hypothesis model leaves room for further verification. This research revealed images shared on social media were associated with memories of previously encountered images and real-life memories, and participants showed a unification of a positive state of emotions with others.

This study reports the results of a subject investigation that was conducted on the cause and effect of the phenomenon known as “kawaii.” To experience that something is “kawaii” is a psychological phenomenon; however, it has not been clarified what type of causes lead to this type of effect. Due to the existence of several opinions regarding what comprises “kawaii,” it is difficult to entirely clarify the topic. Three group interviews were conducted with a total of 30 subjects. The laddering method devised by D. Hinkle was used as the question form, and 15 stimuli were used for the investigation. The causes were classified into “shape,” “behavior or expression,” and “personality ”; the effects were classified into 20 social needs and 16 emotional categories. Regarding the effects of “kawaii,” “happiness” was considerably selected followed by “affiliation” and “nurturance.” Moreover, the relationship between the causes and the effects was further understood.

In this paper, we propose a moral judgment system using distributed representation and associative information. Moral judgment means right and wrong judgment. There are two features in the proposed system. The first one is the usage of distributed representation of sentences. It enables consideration of the meaning of the complicated sentences. Here, the distributed representations adjusted for moral judgment are used to increase the accuracy. The second one is the usage of associative information to consider the related knowledge. In the proposed system, a database of predicate argument structure is constructed by a large corpus (British National Corpus) and is used for association. In the experiments, we compared the proposed system with the judgments by human. We confirmed the effectiveness of the proposed system.
