Emotional state before sleep affects the subsequent sleep onset. The purpose of this study was to investigate how positive/negative emotion before sleep effected hypnagogic state. The movies eliciting positive or negative emotion were presented before sleep. Hypnagogic imagery was recorded as a probe of emotional experience and EEG microstate analysis was used for finding the emotion related EEG activities. The score of emotion ratings for hypnagogic imagery indicated that positive emotion was reported in not only positive condition but also in negative condition. This implied that hypnagogic state might be accompanied by positive emotion. Comparing the appearance of maps obtained from microstate analysis between conditions, the map of right temporal activity was significantly greater in positive condition while the map of the left frontal activity was greater negative condition. These results suggested that the emotion not just in presleep but also in hypnagogic state was involved in sleep onset process.

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.

We examined how changes in participants' heart rate affect their estimation of time when listening to music. We manipulated participants' heart rate using a cycling task on an exercise bike and by varying the tempo of music. The heart rates of 48 participants were measured before and after the pedaling task on the exercise bike. One week later, they listened to the music and estimated the temporal duration (60 seconds) under the non-manipulated condition (without exercise) and heart rate manipulated condition (with exercise). The results showed that the duration of the music (60 seconds) was underestimated after light exercise and overestimated after strenuous exercise. These results suggest that the acceleration of the internal time mechanism due to an increase in the heart rate affects the perceived duration of time with relation to music.

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 face-to-face communication, the listener's body movements are often observed to occur nearly simultaneously with changes in the speaker's voice pattern. This synchronization between speaker and listener is called entrainment. The present study investigated the relationship between classroom seating positions and instructor-student entrainment. Four university instructors individually gave 60-minute lectures to classes of 36-64 students in classrooms. The body movements of the students were captured using a video camera, and the voices of instructors were recorded via a microphone. For each pixel, the covariance between the sound level changes of a instructor's voice and the power of the brightness fluctuations of the pixel was calculated as an index of the entrainment level of each location in the classroom. The results suggested that students sitting in the middle row of the middle column in the classroom showed higher entrainment levels. Moreover, changes of entrainment level were found to reflect changes in student's interest in the lecture.

For the purpose of providing information for the apparel field, the effects of changing the pleat number and skirt length on the visual image of 30 types of pleated skirts by age group were analyzed. The major results are as follows. Changes in the pleat number and skirt length were strongly related to the visual image of pleated skirts; the more pleats there are, the more complicated, dressy and feminine they look, while the fewer pleats there are, the more calm and plain they are regarded. In addition, it was revealed that the shorter the skirts are, the more casual, childlike and simple they look, while the longer they are, the more formal, heavy, mature and luxurious they appeared. Image changes were much more significant for the skirt length than they were for the number of pleats, while for age groups, the number of pleats accounted for much larger differences in visual image than the skirt length. In particular, compared to other age groups, there was a significant difference in image scores for subjects aged 10 to 19 for skirts that were uncommon, and for subjects in their 50s for skirts that gave them a sophisticated and charming image. As a result of principal component analysis, it is considered that the 1st principal component analysis (PC1) largely contributes to an element expressing sensitive fashion image based on expression, while PC2 contributes to the age factor based on activity. However, it was revealed that the items which strongly influence the major components are different by age, as are the items which determine the image of pleated skirts.

Ultra-high definition (4K) imaging allows us to achieve considerably higher image quality than would high definition (HD) imaging. The present study examined how 4K and HD imaging could influence subjective impressions of movies differently, in association with the quantities of motion and fields of view of these movies. We found that stronger impressions regarding comfort and impact were evoked for 4K movies with smaller quantities of motion and medium field of view. Stronger perceptions of impact occurred for HD movies with larger quantities of motion and larger field of view. HD movies also gave stronger impression regarding dynamics regardless of motion quantities. Additionally, HD movies down-converted from 4K movies tended to induce higher impressions regarding evaluation and comfort in some situations. These results suggest that subjective impressions of movies are influenced by the differences in resolution images, as well as interactions between imaging types and characteristics of movie contents.

In recent years, as information equipment has become multi-functional, an easy-to-use interface has been demanded. Particularly, an interface design that can be operated intuitively is urgently required. Therefore, we have re-examined this problem from the point of view of familiarity and organization along the flow of execution of user behavior for the design method, characteristics, and the meaning of an intuitive interface by use of a literature search, a questionnaire survey, and experiments. Based on our results, after reviewing patterns that combine the recognition and operation by a user, we classified interfaces into four types. As a result, we have clarified the characteristics and requirements of an intuitive interface and design guidelines which form the methodological framework of an intuitive interface design. The current study focused on information terminals using a touch panel, but the design guidelines proposed should be applicable to the interface design of various devices.

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.

In this paper, we propose an automatic manzai-dialogue creating system. Manzai is performed mainly by a pair of two comedians. One (called boke) says strange things in a funny way and the other (called tsukkomi) corrects them. This is how they can make their audience laugh. In the proposed system, first, a sentence in a text is changed to a sentence having strange meaning. Then the proposed system produces a sentence which points out the mistakes and sometimes corrects it in a funny way. Tsukkomi does not only correct the mistakes but also compares them to something (called tatoe tsukkomi). By repeating this kind of processing, the proposed system can change a text to a manzai script. MeCab, Japanese language morphological analyzer and Japanese Google N-grams are employed to choose the candidate words considering word similarity and phonological similarity. We conducted experiments to evaluate the proposed system and confirmed the effectiveness of the proposed automatic manzai-dialogue creating system.

This study investigated the basis of a right-side dominance in aesthetic arrangement. In experiment 1, in order to examine the effect of attended position in pictures on aesthetic arrangement, we manipulated the positions of the fixation points, which attract observer's attention, and centroids of triangle arrangement for three objects. Participants rated preference, balance, beauty and harmony by the use of seven points scale for each of the pictures. We found that participants evaluated highly aesthetic in viewing the pictures whose arrangement centroids were near to the fixated position. In experiment 2, in order to examine the effect of participant's dominant hand on aesthetic arrangement we presented the objects which the participants are willing to manually manipulate, or the object which they should avoid to manually touch for right-handed or left-handed participants. We found that right-handed participants evaluated highly aesthetic in viewing the pictures whose arrangement centroid was at right side, but left-handed participant did not.

On-line battle games reached a new stage. It is the movement of making a computer game sublimate for "sport". It is called electronic sport, e -Sports. The leading parts of e -Sports are not a game manufacturer but players. Manufacturers don't have the initiative, but it is the age when a users' community chooses a game. e-Sport develops in America, Europe, South Korea, Taiwan. Even Japan may be so. It may influence not only a market but also culture, education, international relations.

This study investigated how the several factors of BGM (Background music) affected the time estimation . We composed 28 original music tunes with different tempo and notes. Twenty undergraduates estimated one minute by the use of the method of production while listening to a BGM. Results showed that participants underestimated the duration while listening to a tune with a slow tempo, whereas they overestimated while listening to the tunes with fast tempo. The participants overestimated the duration with the increment of the number of the notes per unit time and variety of a note. In addition, the music experiences influenced the auditory time estimation.

This study analyzes the factors for detecting agents to implement a human-like agent in werewolf games, which are new themes in game studies of artificial intelligence. A comparative experiment was conducted to reveal the influences regarding the degree of disclosure of the agent existence; seven players and an agent participated in four games. Communication logs were collected from the game logs. Impressions for each player was reported in questionnaires with five-point scales and detection of the agent were reported in a free writing. Although the most players, who did not know that an agent played the games, did not be aware of the true character of the agent, the most players who knew the existence could detect the agent. The statements of detected agents differed from them of other players. This study concludes that the technical requirement for agents is to adapt to statements of other players.

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.

In recent years, the communication technique known as coaching is getting a lot of attention, and beginning to be implemented in various fields. However, the psychological effect of coaching on healthy individuals remains unclear. In order to rectify this, we have conducted a coaching observation study, and implemented psychological testing to determine its effects in this area. Also, building on the precedent set by other studies, we have carried out analysis of the content of conversation during coaching. The results show a statistical relation between conversation content and the psychological effects of coaching.

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.

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 thesis, the relationship between sound and colour has been analysed with two different methods. First, colours are applied to sounds using the psychological technique that is based on a study on synaesthesia. In the second approach, the ideal tones are linked to hues that are referring to adjectives. However, both methods have their disadvantages. This study investigates the relationship between timbres and colours with quantitative data from tonal structures.In the first step, the relationship between timbres and colours is aggregated by conducting an experiment with subjects. The results are compared with the quantitative structure of the tone colours. From the result, four basic laws that define the causal relationship between timbre and cool or warm colours have been defined: overtone, fundamental frequency, length of sound and decay of sound.

Scent and music are acknowledged to generate physiological and psychological changes on people, and the combination of scent and music is exerted in diverse situations. However, effects and utilization of scent and music in confined resting environment have not been examined exhaustively. To investigate the effects of scent and music on people’s moods and stress in confined resting areas, towards a better understanding about the olfactory and auditory environment, we tested six combinations of scent and music. The results indicated that music hardly changed people’s stress evaluation, but had significant effects on moods. On the other hand, scent dramatically affected both moods and stress assessment. Profound comprehension about scent and music will offer further inspiration for the design of olfactory and auditory environment in confined spaces, and new knowledge and perspectives gained through this exploratory study will serve to the thorough and supplementary research in the future.
