  • This study proposed a Long-Short Term Memory network to consider changes in emotion over time, and applied an attention mechanism to give weights to the emotion states that appear at specific moments. We used 32 channel EEG data from DEAP database. A 2-level classification (Low and High) experiment and a 3-level classification experiment (Low, Middle, and High) were performed on Valence and Arousal emotion model. As a result, accuracy of the 2-level classification experiment was 90.1% for Valence and 88.1% for Arousal. The accuracy of 3-level classification was 83.5% for Valence and 82.5% for Arousal.

  • In approach of human-robot interaction, it is importance task in future robot industry to make to robot recognize, express, coping the emotions. The purpose of this study was to examination the effects unconscious positive and negative emotion of information processing of motor program. 13 participants(male=11, female=2) viewed smile-face picture and angry-face picture priming at 10ms level, and then performanced button press, button press and one tennis ball hitting, and button press and two tennis ball hitting task. The results appeared that positive emotion triggered more fast RT than negative emotion in planning complex motor program. Possible explanations for the performance differences depended on emotion are discussed and future research directions were provided.

  • This study examined the factors affecting the career identity of high school students. We adopted the ecological systems theory by Bronfenbrenner. The consumer typology approach was applied based on their negative emotions, and they were categorized into two distinct groups: unstable emotion group(n=903) and stable emotion group(n=1,107). We used the panel data of Korean Children & Youth Panel Survey. Data of a total of 2,010 participants were analyzed. The results of this study are as follows. In the unstable emotion group, parental supervision, parental excessive expectation, peer communication, peer trust, and teacher attachment significantly influenced career identity. In the stable emotion group, parental supervision, parental abuse, peer communication, and teacher attachment significantly influenced career identity.

  • The present study examined memory accuracy for faces with positive, negative and neutral emotional expressions to test whether their emotional content can affect visual working memory (VWM) performance. Participants remembered a set of face pictures in which facial expressions of the faces were randomly assigned from pleasant, unpleasant and neutral emotional categories. Participants' task was to report presence or absence of an emotion change in the faces by comparing the remembered set against another set of test faces displayed after a short delay. The change detection accuracies of the pleasant, unpleasant and neutral face conditions were compared under two memory exposure duration of 500ms vs. 1000ms. Under the duration of 500ms, the accuracy in the pleasant condition was higher than both unpleasant and neutral conditions. However the difference disappeared when the duration was extended to 1000ms. The results indicate that a positive facial expression can improve VWM accuracy relative to the negative or positive expressions especially when there is not enough time for forming durable VWM representations.

  • The Scale of Positive and Negative Experience (SPANE) is a newly developed emotional scale to measure well-being that was designed to overcome the limitations of the previous emotional scales (Diener et al., 2010). It comprises 12 items that measure positive and negative emotional experiences, including general (e.g., positive, negative) and specific (e.g., joyful, sad) items. It also reflects all levels of arousal. This study examined the factor structure and gender invariance of the Korean version of the SPANE. For this purpose, responses to the scale of a sample of 551 Korean college students (276 males and 275 females) were analyzed. The results exhibited high internal consistency reliability and construct validity for a Korean population. Furthermore, the configural, metric, and scalar invariance of the SPANE held across gender. These results suggest that the Korean version of the SPANE is a valid scale for measuring the emotional experiences of Korean students, and it is appropriate to use in future studies of gender difference in emotional well-being.

  • The purpose of this study was to verify the mediating effect of adaptive/maladaptive cognitive emotion regulation strategies in the relation between perceived spouse's covert narcissism and marital satisfaction. For this purpose, 300 adults who were married in Seoul and Gyeonggi province were subjected to covert narcissism, marital satisfaction, and cognitive emotion regulation strategy scale and analyzed using the SPSS 23.0 program. The results of the study was followed. First, perceived spouse's covert narcissism showed a significant negative correlation with marital satisfaction and adaptive cognitive emotion regulation strategy, whereas it showed a significant positive correlation with maladaptive cognitive emotion regulation strategy. The marital satisfaction showed a significant positive correlation with adaptive cognitive emotion regulation strategy, but a significant negative correlation with maladaptive cognitive emotion regulation strategy. Second, adaptive/maladaptive cognitive emotion regulation strategies partially mediated the effects of perceived spouse's covert narcissism of on marital satisfaction. Based on these results, the implications and limitations of this study and suggestions for future research were discussed.

  • The purpose of this study is to determine the effects of error sources in emotional intelligence assessment of young children. The emotional intelligence of 198 five years old children was assessed using the Emotional Intelligence Scale developed by Lee[14]. Evaluation results were analyzed using G study for generalizability theory. G study results show that parents can be effective evaluators for emotional intelligence in young children. Strategies to reduce error effects are discussed.

  • This study is to examine if emotional valance depending upon the result of baseball game(losing or winning) of subjects' favorite team yields hemispheric asymmetry measured by fMRI. Subjects were twelve fans of the Samsung Lions baseball team. The brain activations have been observed while they watched winning and losing scenes of their favorite team. As a results of the experiment, those who watched winning scenes showed the activation of the left and right cuneus, right inferior occipital gyrus, right inferior frontal gyrus, left amygdala, right parahippocampal gyrus, left uncus, left cingulate gyrus, left inferior temporal gyrus, right middle temporal gyrus, left declive, left culmen. On the contrary, those who watched losing scenes showed the activation in the right middle frontal gyrus, left anterior cingulate, left sub-gyral, left lentifomrm nucleus, left thalamus, left claustrum, left insula. The evidence of hemispheric asymmetry from this study has not been demonstrated and activation in amygdala observed during watching winning scene has not been observed in losing scene. Therefore more in-dept research is required about defeat stimuli induction.

  • The present study was conducted to investigate the influences of emotion priming and the number of negation words on the task of sentential predicate reasoning in groups with or without anxiety symptoms. 3 types of primed emotions and 2 types of stimulus and 3 conditions of negation words were used as a within-subject variable. The subjects were instructed to make facial expressions that match the directions, and were asked to choose the correct answer from the given examples. Mixed repeated measured ANOVA analyses on reaction time first showed main effects for the variables of emotion, stimulus, number of negation words and anxiety level, and the interaction effects for the negation words x anxiety combination. These results are presumably suggested to reflect that externally intervening emotion works on language comprehension in a way that anxiety could delay task processing speed regardless of the emotion and stimulus type, meanwhile the number of negation words can slower language processing only in a anxiety group. Implications and limitations were discussed for the future work.
