  • To elucidate the effect of working memory (WM) load on negative facial emotion processing, we examined ERP components (P1 and N170) elicited by fearful and neutral expressions each of which was presented during 0-back (low-WM load) or 2-back (high-WM load) tasks. During N-back tasks, visual objects were presented one by one as targets and each of facial expressions was presented as a passively observed stimulus during intervals between targets. Behavioral results showed more accurate and fast responses at low-WM load condition compared to high-WM load condition. Analysis of mean amplitudes of P1 on the occipital region showed significant WM load effect (high-WM load > low-WM load) but showed nonsignificant facial emotion effect. Analysis of mean amplitudes of N170 on the posterior occipito-temporal region showed significant overall facial emotion effect (fearful > neutral), but, in detail, significant facial emotion effect was observed only at low-WM load condition on the left hemisphere, but was observed at high-WM load condition as well as low-WM load condition on the right hemisphere. To summarize, facial emotion effect observed by N170 amplitudes was modulated by WM load only on the left hemisphere. These results show that early emotional processing of negative facial expression could be eliminated or reduced by high load of WM on the left hemisphere, but could not be eliminated by high load on the right hemisphere, and suggest right hemispheric lateralization of negative facial emotion processing.

  • The purpose of this study was to explore the normative expectations of positive emotions such as happiness and pride in Korean culture by analyzing the children's textbooks in the Chosen Dynasty period. The method of this study was document analysis and the materials for analysis were 'Dongmongsensp', 'Gyukmongyogyul', 'Myungimbogam', and 'Sohak', that were the textbooks for children's education and invoked the ethics of individual life based on Confucianism. The analysis was focused on the antecedent events, emotional consequences, and emotional regulation in the emotional process of happiness and pride. According to the analysis, happiness was caused by the accomplishment of cultural tasks such as supporting parents, observing laws, being moderate, improving oneself with reading good books, and modeling good deeds, as well as parents' love, which had desirable consequences. Hence, the emotional regulation was to enhance happiness, but far as immoderate experience of happiness, the regulatory rule was expected to suppress it. Also, the antecedents of pride were those demonstrating to have power or occupying a high social position, and the consequences of pride led to self-destruction, and pride was therefore not allowed to be expressed. Consequently, happiness was enhanced because it motivated individuals to accomplish cultural tasks of interdependence, whereas pride was inhibited because it tended to disengage self from social connectedness.

  • Decades of psychological research have shown that emotion brings users various kinds of physical and psychological advantages and disadvantages. Moreover, this also impacts human decision-making. However, in spite of the weight of emotion, combined with HCI, relevant research is still insufficient. We hypothesized that the user's temporal emotion could influence the product evaluation, especially in terms of product usability. Two studies were carried out to investigate the effect of induced priming on user evaluations. In exp1, we manipulated participants' temporal emotions using positive and negative images from IAPS. In our results, we saw image priming had a statistically significant effect, with the positive condition group giving the product high ratings for usability. In exp2, emotional image manipulation was conducted with valence and arousal. As a result, we found that the variables of valence and arousal had some interaction effects. These studies have demonstrated that temporally induced emotion could affect users' emotion in different ways, in addition to influencing product evaluations.

  • 우리나라는 음주에 대해 비교적 관대한 정서적 문화를 가지고 있으며, 청소년 음주도 흡연이나 약물 등 다른 비행에 비교해 본다면 상대적으로 경미하다고 판단하는 경향이 있다. 그러나 청소년 음주행위는 건강에 해로운 또 다른 약물과 물질의 오ㆍ남용을 불러오는 길잡이 노릇을 하며, 정서적으로 안정되지 못하고 심리적 갈등이 유발되기 쉬운 청소년기에 흥분이나 거친 행동 등 각종 비행의 원인이 될 수 있을 뿐 아니라, 이 시기에 잘못 길들여진 음주 습관은 일생동안 계속되고, 후에 술로 인한 질병에 걸리거나 알코올 의존자가 되어 일생을 그르칠 가능성이 높다.(중략)

  • The study is to examine how facial EMG responses change when children experience a positive emotion(happiness) and a negative emotion(fear). It is to prove that the positive emotion(happiness) could be distinguishable from the negative emotion(fear) by the EMG responses. Audiovisual film clips were used for evoking the positive emotion(happiness) and the negative emotion(fear). 47 children (11-13 years old, 23 boys and 24 girls) participated in the study Facial EMG (right corrugator and orbicularis oris) was measured while children were experiencing the positive or negative emotion. Emotional assessment scale was used for measuring children's psychological responses. It showed more than $85\%$ appropriateness and 3.15, 4.04 effectiveness (5 scale) for happiness and fear, respectively. Facial EMG responses were significantly different between a resting state and a emotional state both in happiness and in fear (p<001). Result suggests that each emotion was distinguishable by corrugator and orbicularis oris responses. Specifically, corrugator was more activated in the positive emotion(happiness) than in the negative emotion(fear), whereas orbicularis oris was more activated in the negative emotion(fear) than in the positive emotion(fear).

  • Today's employees are facing various socio-emotional problems due to the lack of appropriate supports and intervention in the workplace. These problems, however, cause considerable stress and inflict fatal damage on the quality of the employees' lives. Thus, this study analyzed the negative effects of the employees' socio-emotional problems on their stress, depression, and a sense of self-esteem. As a result, the study has identified that the problems occurred widely in the work life area such as job-related problem, predicament of retirement, workplace violence, family life area such as family relationship, child education, crisis problem, and lastly culture and health related area. This study also found that the socio-emotional problems in the three areas were the main stressors after all and they once again negatively affected depression and a sense of self-esteem. However, the role of social support, which is known to have the buffering effect on depression and a sense of self-esteem, was not sufficiently proved. This strongly implies that traditional social supports necessarily have limitations to overcome employees' socio-emotional problems in hand and thus systematic intervention toward the troubled workers in the organizational level must be required.

  • Various imperative statements that can be represented in the way in which the product or service is used describe how or how to achieve the goals, or induce or prohibit a specific action. This study focuses on The Effects of age and type of imperative sentence (directive vs. declarative) on behavioral intention and recall. As a result of the experiment, older people who have shorter lives remaining access information in a more emotional way, so they have been rejected by directive (vs. declarative) statements that felt more negative feelings, resulting in lowered behavioral intention. Conversely, the negative feeling caused by directive statements increased salience of directive (vs. declarative) sentence for older people more, which in turn increased memory for older people. Process analysis showed that emotions when exposed to statements mediated these results. The results of this study show that in order to improve consumers' behavioral response and/or the performance of information processing, it is necessary to deeply consider their age and how to construct the statement.

  • Current researches on emotion detection classify emotions by using the information from facial, vocal, and bodily expressions, or physiological responses. This study was to review three representative emotion recognition methods, which were based on psychological theory of emotion. Firstly, literature review on the emotion recognition methods based on facial expressions was done. These studies were supported by Darwin's theory. Secondly, review on the emotion recognition methods based on changes in physiology was conducted. These researches were relied on James' theory. Lastly, a review on the emotion recognition was conducted on the basis of multimodality(i.e., combination of signals from face, dialogue, posture, or peripheral nervous system). These studies were supported by both Darwin's and James' theories. In each part, research findings was examined as well as theoretical backgrounds which each method was relied on. This review proposed a need for an integrated model of emotion recognition methods to evolve the way of emotion recognition. The integrated model suggests that emotion recognition methods are needed to include other physiological signals such as brain responses or face temperature. Also, the integrated model proposed that emotion recognition methods are needed to be based on multidimensional model and take consideration of cognitive appraisal factors during emotional experience.

  • This study examined affective representation by analyzing physiological responses measured using wearable devices and affective ratings in response to emotional videos. To achieve this aim, a published dataset was reanalyzed using multidimensional scaling to demonstrate affective representation in two dimensions. Cross-participant classification was also conducted to identify the consistency of emotional responses across participants. The accuracy and misclassification in each emotional condition were described by exploring the confusion matrix derived from the classification analysis. Multidimensional scaling revealed that the represented objects, namely, emotional videos, were positioned along the rated valence and arousal vectors, supporting the core affect theory (Russell, 1980). Vector fittings of physiological responses also showed the associations between heart rate acceleration and low arousal, increased heart rate variability and negative and high arousal, and increased electrodermal activity and negative and low arousal. Using the data of behavioral and physiological responses across participants, the classification results revealed that emotional videos were more accurately classified than the chance level of classification. The confusion matrix showed that awe, enthusiasm, and liking, which were categorized as positive, low arousal emotions in this study, were less accurately classified than the other emotions and were misclassified for each other. Through multivariate analyses, this study confirms the core affect theory using physiological responses measured through wearable devices and affective ratings in response to emotional videos.

  • We investigated the brain activity in perceiving the emotional stimuli between a science invention group(n=13) and a general group(n=13). The science invention group, which mostly consisted of recipients of creativity prizes, scored 96% on creative personality tests(WKOPAY, SAM), whereas the general group performed at an average level on these tests. Analyzing the brain activity in perceiving the emotional stimuli(IAPS pictures), the science invention group than the general group showed higher activity in certain areas, such as MTG, STG, and so on. When correlation analysis was performed on the creative personality score and brain activity, MTG, STG, and so on areas showed significant correlations. There were more correlation areas in valence than in arousal. These results show that scientific creativity is related to emotional susceptibility. Thus, we insist that emotion be considered in the assessment and education programs for the gifted in science.
