The purpose of the paper is to examine sidedness effects of comparative advertising and moderating roles of the emotions of customer and product type. To test the research hypotheses, this study conducted experimental designs. One hundred ninety-two undergraduate students were assigned to one of the four experimental groups. Comparative Advertising message type and product type were manipulated as between-subject factors. There was a surprising event situation(free gift event) when participants came to laboratory for experiment, which is for the emotion manipulation. If a participant in a positive emotion group, he or she gets a free gift. The data demonstrate that comparative message type have a significant effect on both attitude toward the advertising and acceptance intention. In addition, consumers' emotion and product type play a significant moderating role between the message types and the dependent variables. The results of this study contribute to the literature as a new attempt to examine the sidedness effect of the comparative advertising message. We suggested that message types and consumer's emotion is one of very important aspects for a comparative advertising and marketers should consider people's emotion when they release a comparative advertising, which can help when marketers make their strategy for a comparative advertising.

This study examined the difference in memories for emotional stimuli. After giving participants the memory task instruction that they should remember the given stimuli, the emotion-induced photographs and the neutral photographs were presented. To minimize the possibility to regulate the expressions of their mood which induced by emotional stimuli and to find out whether the antecedent-focused emotion regulation process would damaged the memory of emotional stimuli in men, participant's memory was measured directly after the presentation of each photograph by free reflection method. Also Sex differences in memories about emotional and neutral stimuli were measured and compared. Women memorized stimuli more than men, and as expected, women remembered more about the emotional stimuli than neutral ones. The analysis of sex difference about central and peripheral features indicated that women remembered central features of emotional stimulus more than those of neutral ones, but that men had no difference between central features of emotional stimuli and those of neutral ones. These results showed that men's damaged memories of emotional stimuli were caused by the antecedent-focused emotion regulation process.

The purpose of this study was to investigate the effects of marital conflicts on dyadic adjustment and the mediating effects of positive emotion and sex-role attitude. The participants were total 270 middle-aged married people and data was collected from April 12 to June 24 in 2014. The data was collected with structured questionnaire and analyzed with the SPSS 17.0 and AMOS 18.0 programs. Results were as follows. First, marital conflicts had a significant direct effect and indirect effect through the mediation of positive emotion on dyadic adjustment. Second, positive emotion had a significant mediating effect but sex-role attitude did not. Third, The modified model showed a good fitness indices( ${\chi}^2$=38.90 standardized ${\chi}^2$=1.77(CMIN/df), GFI=.97, AGFI=.94, NFI=.98, SRMR=.02, CFI=.99, RMSEA=.05) and explanation power was 88.9%. These results suggest that middle-aged dyadic adjustment can be improved by increasing positive emotion. This study results will be contribute to develop intervention program for enhancement of marital relationship and education program for middle-aged.

Objectives The purpose of this study was to examine the effects of positive and negative emotion on the quality of life(QoL) in each Sasang contitution, using Positive Affect and Negative Affect Schedule(PANAS) and Short Form-12 Health Survey Questionnaire(SF-12) questionnaire. Methods A total of 1,123 participants completed the Korean version of the PANAS and SF-12 questionnaire. The participants were classified into one Sasang constitution by QSCC II. The effects of emotion on the QoL were compared between the each Sasang contitution using analysis of variance(ANOVA). Results We found significant differences between constitutions in Positive Affect(PA), PA-Joy, PA-Interest and PA-Activation of PANAS. And we found significant differences between constitutions in Mental Component Summary(MCS) of SF-12. Negative correlation of less -0.4 was shown in Negative Affect(NA), NA-Afraid, NA-Upset of PANAS and MCS of SF-12. Conclusions The Soyangin has significantly higher score than Soeumin in PA, PA-Joy, PA-Interest and PA-Activation of PANAS as previous studies. This study also shows the correlation between negative emotion and decline in the quality of mental status.

This study identified heart response of participants while listening to sounds which have 1/f fluctuations with exponent ${\alpha}$ gradient. The participants were engaged in emotional stress work. Prior studies related to 1/f fluctuation sound have reported that sound source can alleviate psychological and physiological state of users. Subjects of this study were exposed to sound with three levels of ${\alpha}$ gradient. Heart response of subjects were measured with Photoplethysmography(PPG) sensor simultaneously. The dependent variables of this study were beat per minute(BPM), very low frequency percent of pulse rate variability (VLF percent), the standard deviation of all normal RR intervals (SDNN), and high frequency power(HF power). Subject showed arousal response when exposed to sound with exponent ${\alpha}$ gradient of 3 whereas the sound with exponent ${\alpha}$ gradient of 1 and 2 resulted in relax effect. The characteristic of 1/f fluctuation sounds can be applied to alleviate stress for employers under emotional labor.

Many studies have shown that musical dissonance generally evokes negative affect, but few studies detail how distinct dissonant intervals, ranging in various roughness, influence emotions and cognition. This research entailed two experiments to confirm whether varying musical intervals of dissonance trigger particular negative emotions and increase cognitive interference. Experiment 1 assumed that different dissonant intervals would elicit distinct negative emotions. In a survey involving 131 participants, there was an overwhelming consensus that dissonant intervals elicited stronger high arousal negative affect than low arousal negative affect. The major 7th degree was found to evoke a significantly stronger feeling of scared. Experiment 2 investigated whether emotions-affecting dissonance would have an enhancing effect on cognitive interference. According to a color-word Stroop task conducted on 81 participants, the presence of any dissonant sound caused significantly higher reaction times and error rates than in the absence of sound. In particular, the minor 2nd degree was cognitively the most disruptive and associated with the slowest reaction times. This paper shows how different ranges of dissonance can effectively influence negative affect and heighten cognitive interference.

According to the core affect theory, affect consists of two independent dimensions of valence and arousal. Previous studies have found that various types of stimuli, such as pictures, videos, and music, are mapped onto the core affect space. However, the research on affect using gustatory stimuli has not been explored sufficiently. This study investigated whether the affects elicited by tastes could be mapped onto the core affect space. Stimuli were selected based on two factors (taste types and intensity). Participants were presented with each stimulus, evaluated the tastes, and rated their affective responses on taste and emotion scales. The data were analyzed using repeated-measures ANOVAs and multivariate analyses (multidimensional scaling and classification). The results of univariate analyses indicated that participants felt positive for sweet stimuli but negative for bitter and salty. Furthermore, participants reported high arousal with high intensity. Multidimensional scaling revealed that taste stimuli are also represented on the core affect dimensions. Specifically, it was confirmed that in the first dimension, sweetness was represented as a positive affect, while bitter and salty tastes were represented as a negative affect. In the second dimension, bitterness was represented as low arousal and sourness as high arousal. Classification analyses confirmed that the taste was identified consistently based on the affective responses within and across participants. This study showed that the taste stimuli in daily life are also located on core affect dimensions of valence and arousal.

An accurate prediction of emotion is a very important issue for the sake of patient-centered medical device development and emotion-related psychology fields. Although there have been many studies on emotion prediction, no studies have applied the heart rate variability and neuro-fuzzy approach to emotion prediction. We propose ANFEP(Adaptive Neuro Fuzzy System for Emotion Prediction) HRV. The ANFEP bases its core functions on an ANFIS(Adaptive Neuro-Fuzzy Inference System) which integrates neural networks with fuzzy systems as a vehicle for training predictive models. To prove the proposed model, 50 participants were invited to join the experiment and Heart rate variability was obtained and used to input the ANFEP model. The ANFEP model with STDRR and RMSSD as inputs and two membership functions per input variable showed the best results. The result out of applying the ANFEP to the HRV metrics proved to be significantly robust when compared with benchmarking methods like linear regression, support vector regression, neural network, and random forest. The results show that reliable prediction of emotion is possible with less input and it is necessary to develop a more accurate and reliable emotion recognition system.

To create urban landscapes that take human emotion into consideration, the present study verified the psychological effects of artificial waterscape facilities on users, as these facilities significantly impact their psychological comfort. Data was collected using the SD scales and POMS of 60 male and 60 female participants after they watched a video of four waterscape facilities. Participants deemed the video clip of a fountain waterscape to be artificial and linked it with changeable images that increased their vigor. The video clip of waterfall stimulated various impressions (e.g., vital, liked, active, etc.) and changed participant' mood states by increasing their vigor and decreasing fatigue. The video clip of the pond yielded familiar impressions, produced less free images, and decreased tension among participants. Finally, the video clip of the stream stimulated quiet and comfortable images as well as reduced negative feelings of anger, confusion, and depression among participants. Furthermore, males experienced more positive effects than females, regardless of the type of waterscape facility. The study findings indicate that the four different waterscape facilities influenced participants' mood states. Additionally, the psychological effects differed by gender. The data suggest that landscape planners need to carefully consider their choice of waterscape facility when designing green spaces to ensure that the space is psychologically comforting to users.

The purpose of this study is to clarify the constructs of emotion suppression and help understanding on the multidimensional nature of emotion suppression by classifying constructs for suppression according to the KMW model. Also, this study examined the gender differences of emotion suppression. For this purpose, 657 adult male and female subjects were evaluated for attitude toward emotions, and difficulty in emotional regulation, as well as depression, state anger and daily stress scale. As a result of the exploratory factor analysis on the scales related to the emotion suppression factors, the emotion suppression factors corresponding to each stage of the KMW model were found to be 'distraction against emotional information, 'difficulty in understanding and interpretation of emotions', 'emotion control beliefs', 'vulnerability on emotional expression beliefs'. Next, the study participants were classified by performing a cluster analysis based on each emotion suppression factor. As a result, four clusters were extracted and named 'emotional control belief cluster', 'emotional expression cluster', 'emotional attention failure cluster', and 'general emotional suppression cluster'. As a result of examining the average difference of male depression, depression, state anger, and daily stress for each group, significant differences were found in all dependent variables. As a result of examining whether there is a difference in the frequency of emotional suppression clusters according to gender, the frequency of emotional suppression clusters was high in men, and the ratio of emotional expression clusters was high in women. Finally, it was analyzed whether there was a gender difference in the effect of the emotional suppression cluster on psychosocial adaptation, and the implications were discussed based on the results of this study.
