LED lighting has an advantage of adjusting color temperature. This change of color temperature may derive change in behavioral and physiological responses of the visual perception for indoor environments. This research examined the changes of behavioral and physiological responses caused by the color temperature. The environment was configured that the indoor temperature was 20 degrees centigrade or less as the perceived uncomfortable environment in winter. Then, the comfortable sensation vote (CSV) and the results of 3-back working memory test were measured as behavioral responses. In addition, the Electrodermal Activity (EDA) and Electrocardiogram (ECG) were measured as the responses of autonomics nervous system (ANS) in the three conditions of color temperature (red: 3862K, white: 5052K, blue: 11,460K). As a result, behavioral responses were not significant by the condition of color temperature, but the tendency of occupants' physiological relaxation appeared in the blue color temperature condition compared with the white color temperature condition. Although the color temperature of LED lighting might be a small factor in terms of the characteristics of indoor environment, it suggests that the color temperature could have an impact on the physiological changes in the parasympathetic nervous system.

In this paper, we propose the new emotion model and the robot behavior decision model based on proposed emotion model. As like in human, emotions are hierarchicalized in four levels (momentary emotions, mood, attitude, and personality) and are determined from the robot behavior and human responses. They are combined with motivation (which is determined from the external stimuli) to determine the robot behavior.

Using ordors with the different concentration of essential oils, e studied the effect of a pleasant olfactory stimulation on physiological responses. we examined psychological response, mental task and changes in cardiac, immunity and EEG in responses to 150times solution (feel easily) and 500times solution (feel with difficulty) which of essential oil (called PCK) were diluted in propylene glycol, and neutral (water). The 150times solution that was felt pleasant produced significant differences (p<0.05) in relative power change of beta activity in the left frontal region (Fp1, F3, F7) of the brain, and heart rate (HR) deceleration after mental task. these results are consistent with substantial research that has documented cardiac and EEG responses to pleasant stimuli. What is more, 150times solution increased the concentration of s-IgA know as an index of immunity.

By investigating Internet shopping malls from a viewpoint ofenvironmental psychology, this study tries to expand the subject of servicescape into the Internet rather than to confine it to physical space. This study empirically validates the effect of e-servicescape (hereinafter e-scape) on customers' cognitive and emotional responses which subsequently can lead to customers' behaviors. An analysis of 490 questionnaires found that e-scape influences the emotional and cognitive responses, ultimately triggering customers' behaviors. We also found that the effects of e-scape on customers' behavior may be mediated by customers' internal responses. Based on the analysis result, servicescape management is important on the Internet just as it is in physical space. Concepts such as e-scape management can be one of the effective strategies to make an Internet shopping mall distinguishable from other Internet shopping malls.

The social behaviors of 177(84 girls, 93 boys) 5-6 year olds were rated by the SCBE teacher questionnaire. Mothers reported on their reactions to children's negative emotions and on children's emotionality by questionnaires. Results showed that girls' emotionality was related to maternal punitive responses and their withdrawn behaviors. Maternal emotion-focused reponses were associated with boys' social behaviors. Maternal distress reactions were correlated with girls' prosocial behaviors; maternal punitive responses were related to girls' prosocial and withdrawn behaviors. Maternal emotion-focused responses were associated with girls' aggressive behaviors. Partial correlation analysis indicated girls' emotionality was not related to their withdrawn behaviors when maternal punitive responses were taken into account.

A new device introducing brief pulses of odorozed air synchronized with subject's respiration to human subjects creating a positive response was developed. By the using superimposition technique of an evoked potential the positive responses to skatole in normal subject's were distinguishable. The odorant pulse trigger was the subject's respiration. Responses to aerosolized skatole consisted mainly of a positive wave with a peak latency of approximately 150 ms. In our cases, saturation of responses was found after 4-5 averagings with the responses becoming most clear after 7-8 averagings. And in cases of Alzheimer disease very quick adaptation was recognized.

감성을 인식하고 반응하는 감성컴퓨터를 개발하기 위한 감성인식에 대한 연구가 활발하다. 본 연구는 2차원으로 정의한 감성을 측정하기 위해서 시간에 따른 생리신호의 반응 변수를 정의하고 그 변수로 인한 감성을 구분하고자 하였다. 10명의 대학생에게 16장의 감성을 유발시킬 수 있는 이미지를 제시하였다. 그리고 자율신경계 반응으로 ECG(electrocardiogram), PPG(photoplethysmogram), GSR(Galvanic skin response), RSP (respiration), 그리고 SKT(skin temperature)를 측정하였다. 본 연구는 자율신경계 반응에 대해 Delay, Activation, Half recovery 그리고 Full recovery로 이루어진 TDP(Time Dependent Parameters)를 정의하고 감성을 구분할 수 있는지에 대한 통계적 유의성을 검증하였다. 그 결과, TDP가 감성을 구분할 수 있는 유의미한 변수로 확인하였고 특징적 경향을 보임을 알 수 있었다. 그러므로 본 연구는 TDP가 감성 인식을 위한 유효한 변수일 가능성을 보였다.

I Previous scrolling-shooter games cannot represent various emotions of characters as a personality and situations, so it can only represent simple and momentary emotions. This paper purpose to develop and applying an artificial emotion which gives emotional responses and actions to character as a personality and situations of a character. So we proposed an artificial emotion that receives emotional stimulus, analyzes what emotion will be generated, controls various emotions by a personality and time, and exports a current emotion. To visualize and to test an artificial emotion, We made a scrolling shooter game which has two characters who have a different personality each other. And we applied an artificial emotion to that game, modified it to be able to change status as emotions. To estimate a satisfaction of a artificial emotion for a scrolling-shooter game, we made up a question to two groups-one has people who likes a scrolling shooter game, the other has people who doesn't.

Autonomic responses were analyzed in 323 college students exposed to visual stimulation with Korean Affective Picture System (KAPS). Cardiac, vascular and electrodermal variables were recorded during 30 sec of viewing affective pictures. The same slides intended to elicit basic emotions (fear, anger, surprise, disgust, sadness, happiness) were presented to subjects in 2 trials with different experimental context. The first time slides were shown without any instructions (passive viewing), while during the second with instruction to exert efforts to magnify experienced emotion induced by pictures (active viewing). The aim of the study was to differentiate autonomic manifestations of emotions elicited by KAPS stimulation and to identify the role of instructed emotional engagement on physiological response profiles. The obtained results demonstrated reproducibility of responses in both trials with different contexts. Pairwise comparison of physiological responses in emotion conditions revealed the most pronounced differentiation for "ear-anger" and "fear-sadness" pairs (in electrodermal and HR variability parameters). "Fear-surprise" pair was also well differentiable. The typical response profile for all emotions included HR acceleration (except happiness and surprise), an increase of electrodermal activity, and a decrease of pulse volume. Higher cardiovascular and electrodermal reactivity to fear observed in this study, e.g., as compared to data with IAPS as stimuli, can be explained by cultural relevance and higher effectiveness of KAPS as stimuli, can be explained by cultural relevance and higher effectiveness of KAPS in producing certain emotions such as fear in Koreans.
