To investigate how the valence of unattended background picture modulates perceptual processing of a target letter, participants were required to detect a target letter among six letters superimposed on an IAPS picture. Perceptual load was manipulated by varying the difficulty of letter detection, and behavioral results showed more accurate and faster detection responses at the low-load condition than at the high-load condition. The analysis of ERP data of control condition at which six letters were presented without an IAPS picture showed perceptual load effects on mean amplitude of N1 and P1 ERP components. At experimental condition including an IAPS picture, interaction between valence and perceptual load was observed on mean amplitude of N1 at posterior visual processing area, and the amplitude difference between low-load condition and high-load condition was larger on a negative background picture than on a neutral background picture. The results suggest that more attentional capacity might be consumed by a negative picture than by a neutral picture, and suggest that unattended affective picture is processed automatically and influence the early perceptual processing of target stimulus.

This study examines undergraduate nursing students' user satisfaction and affective experience of collaborative information behavior in a group-based learning through survey method to see the relationship between these factors. For this purpose, the affective experiences (positive and negative aspects) of collaborative information search were examined using the PANAS scale through the same questionnaire. Correlation between students' experiences of collaborative information search and affective aspects were examined, and statistical significance using the t-test were also conducted to measure the relationship among students' demographic factors, experiences of collaborative information search and affective aspects. The results revealed that there was a significant correlation between experiences of collaborative information search and affective aspects. Also, there were significant relationships among students' demographic factors, experiences of collaborative information search and affective aspects. In particular, there were signigicant differences in students' overall satisfaction of collaboration and positive aspects between male and female students who experienced collaborative information search. This study found out the possibilities for a follow-up study for affective aspects in collaborative information behavior.

This study investigated the effects of maternal acceptance attitudes towards children's emotional expressiveness and children's emotional intelligences on peer interaction. A total of 145 Korean mothers with children from 3-5 years old and children's teachers were selected from 4 kindergartens and 6 daycare centers in Incheon and Kyunggi areas. The results were as follows. First, generally, children's emotional intelligence was significantly different depending on gender of the children. Second, there was no difference based on age and gender in maternal acceptance attitudes towards a child's positive emotional expressiveness, but there was a difference based on gender in maternal acceptance attitudes toward a child's negative emotional expressiveness. Third, the children's positive peer interaction was significantly different depending on gender of the children, but the children's negative peer interaction was significantly different based on age and gender of the children.

The depression and anxiety are the most popular mental disorders and not easy to distinguish because of their lots of similarities in the diagnostic criteria, related theories, and clinical symptoms. In this article, we developed the affect scale for distinguishable diagnosis, utilized the relationships between the Positive and Negative affect, and the depression and anxiety. We made up the seed scale of the items which selected by partial correlation, and set the scoring up by multiple regression method. The Multi-dimentional affect scale is reliable and working similarly as the scales used before, but less correlated to each other. We conclude that the affect scale achieved the diagnosis for distinguish between depression and anxiety. Our suggestions for the further study are to redeem the cultural differences, modify by the elaborate methods, and validate by the actual clinical data.

We made Korean IAPS through measuring Korean university students' emotional response(arousal and emotional valence) about the whole 956 IAPS pictures made by Lang et al.(2005). In addition, we examined the emotional difference between American and Korean by comparing the response of original American IAPS and those of Korean IAPS. The results showed that both response of arousal and emotional valence in Korean were highly correlated with those in American respectively. In details, two groups showed differences as well as similarities. Korean showed higher arousal response than American, but in both groups women showed higher arousal response than men. When examining the emotional valence of positive, neutral, and negative stimuli categorized by American IAPS, Korean showed more modest emotional valence than American, and this group difference was the same in both men and women. In particular, Korean women showed more negative emotional valence than Korean men, but American women showed more extreme emotional valence than American men. These results suggest that there are some cultural and sex differences in the emotional response, and that researchers have to consider them when studying with IAPS stimuli.

The purpose of the current study is to investigate how task-irrelevant affective priming affects higher cognitive function. In the study, we selected prime stimuli from International Affective Picture System(IAPS) and examined if they influence participants' performance of syllogistic reasoning task when they are task-irrelevant. In Experiment 1, arousal of IAPS stimuli was controlled while valence of the stimuli was manipulated. In Experiment 2, valence of IAPS stimuli was controlled while arousal of stimuli was manipulated. In both experiments, task-irrelevant affective primes were followed by syllogistic reasoning tasks consisting of three sentences and measured accuracies of task performance. The results showed that valence of affective prime affected logical validity of reasoning and belief-bias whereas arousal of affective primes did not yield any difference. That is, positive valence facilitated logical and analytic processing by reducing belief-bias while arousal did not affect reasoning task performance. These results suggest that dimensions of valence and arousal independently influence higher cognitive function.

Problematic behaviors have been among adolescent population in school and home. Problematic behavior manifested in childhood and adolescence is reported to be a good predictor for adult criminal behavior although no clear factor to cause was identified. Based on literature review on this subject, our hypotheses that delinquency and aggressive behaviors are associated with brain information processing and emotionality in adolescents was developed and this study aimed to test these hypotheses. 1,479 male and female middle school students were selected and given the Trait Meta-Mood Scale, Korea Youth Self Report-Child Behavior Check List and Brain Preference Indicator Test. The main results are as follows: 1) Subjects with problematic behavior compared to average students showed a significant difference in sub-variables of emotionality ant the characteristics of brain information processing. 2) Young adolescent's emotionality and brain information processing characteristics have effects on problematic behaviors. 3) However, the effect on aggression and delinquency was different by gender.

Objective: The purpose of this study is to determine oriental medical concept of emotional intelligence, and to develop the ways of treatment. Methods: We investigated the literature of the oriental and western medicine about an emotional intelligence. Results: Regarding an emotional intelligence from the oriental medicine, it will follow in attributes of five elements(五行), five emotions(五志), seven passions(七情). Due to the five emotions and seven passions will take to control themselves with following the principle of poles at interinhibition, and intergeneration among the five phases. There is a possibility of trying to apply in reflection control of emotion(partIV). Five emotions(五志), depression theories(鬱症), and a control of theories of seven passions(七情調節) will be applied an emotional stability and an emotional control. Conclusion: This study showed that oriental medicine has more merits better than western medicine about emotional intelligence, because oriental medicine consider that the body and mental is an inseparable relation. The further study is necessary with the concept formulation and a historical investigation about an emotional intelligence.

In this paper, we propose an study of the facial emotion recognition considering the dynamical variation of emotional state in facial image sequences. The proposed system consists of two main step: facial image based emotional feature extraction and emotional state classification/recognition. At first, we propose a method for extracting and analyzing the emotional feature region using a combination of Active Shape Model (ASM) and Facial Action Units (FAUs). And then, it is proposed that emotional state classification and recognition method based on Hidden Markov Model (HMM) type of dynamic Bayesian network. Also, we adopt a Harmony Search (HS) algorithm based heuristic optimization procedure in a parameter learning of HMM in order to classify the emotional state more accurately. By using all these methods, we construct the emotion recognition system based on variations of the dynamic facial image sequence and make an attempt at improvement of the recognition performance.
