Objectives: The current study aims to develop Korean Social Affective Visual Stimuli (K-SAVS) to arouse social affect. Methods: K-SAVS is composed of pictures of social situations among East Asians. Each picture contains a negative, positive, or neutral affect. Positive and negative stimuli were presented to one group of subjects. Negative and neutral stimuli were presented to another group of subjects. All subjects were required to fill out Affective Valence and Arousal Manikin. Results: In the initial test, 18 positive affective stimuli pictures (1 set) and 36 negative affective stimuli pictures (2 sets) were chosen from 95 stimuli pictures. Positive affective stimuli pictures showed higher valence (p < 0.001) and lower arousal (p < 0.001) than negative affective stimuli pictures. In the confirmatory test, 18 neutral stimuli pictures (1 set) were additionally selected out of the total of 79 pictures of neutral stimuli pictures and the pictures used in the former experiment. Neutral stimuli pictures showed higher valence (p < 0.001) and lower arousal (p < 0.001) than negative affective stimuli pictures. Conclusion: K-SAVS can be a valid and useful tool for inducing specific social affects of Koreans.

Negative emotions play an important function as to human's existence. In this research, we employed the audio-visual film clips to induce negative emotions and examined the classified responses in the autonomic nervous system(ANS) due to each negative emotion.30 adults(22.6 years $old{\pm}1.24$, 15 males and 15 females) took part in this experiment. Through the preliminary experiment, 2 minutes film's stimuli were selected as the emotion-induced stimuli. During the period when participants were viewing and listening to the selected movie, EDA and ECG were examined as soon as one stimulus was displayed, participants were tested by completing the psychological appraisals of their experienced emotion due to each emotional stimulus. With regard to the result of analyzing the psychological responses, each negative emotion appropriately and effectively induced its target emotion. While concerning the result of analyzing ANS responses, each negative emotion induced its respective activation in ANS. What is more, compared with other types of negative emotional stimuli, the scaring stimulus induced higher activation of the sympathetic nervour system(SNS) as to the indexes in EDh and ECG. This research made segmentation of ANS responses to each negative emotion, which has its significance.

Objects : The aim of this study was to determine whether the P3 elicited by the negative emotional stimuli is different to that by positive stimuli. Methods : We measured the event-related potentials, especially P3 elicited by the facial photographs in 12 healthy subjects. Subjects were instructed to feel and respond to the rare target facial photographs imbedded in frequent non-target checkerboards. Results : We found that amplitude of P3 elicited by negative emotional photographs was significantly larger than that by the positive stimuli in healthy subjects. Conclusion : These findings suggest that P3 elicited by facial stimuli may be used as a psychophy-siological variable of the emotional processing.

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.

This study tries to explore that the relationship between social media company's coercive and involuntary marketing stimuli and the negative consequences that have not been intensively discussed in measuring the performance of social media companies. To reflect the influence of the socio-cultural environment of country, a comparative study was conducted on major social media market in Korea and China. As result of the verification, it was found that coercive marketing stimuli had influence on social media firm's negative consequences. And there are significant differences by country in the effect of company's coercive marketing stimulus on user attitudes and negative performance. The results of this study are expected to provide practical implications for the operation of social media firms and individuals who want to do business using social media.

This study examined the effect of emotional sounds on satisfaction of search (SOS). SOS occurs when detection of a target results in a lesser chance of finding subsequent targets when searching for an unknown number of targets. Previous studies have examined factors that may influence the phenomenon, but the effect of emotional sounds is yet to be identified. Therefore, the current study investigated how emotional sound affects magnitude of the SOS effect. In addition, participants' eye movements were recorded to determine the source of SOS errors. The search display included abstract T and L-shaped items on a cloudy background and positive and negative sounds. Results demonstrated that negative sounds produced the largest SOS effect by definition, but this was due to superior accuracy in low-salient single target trials. Response time, which represents efficiency, was consistently faster when negative sounds were provided, in all target conditions. On-target fixation classification revealed scanning error, which occurs because targets are not fixated, as the most prominent type of error. These results imply that the two dimensions of emotion - valence and arousal - interactively affect cognitive performance.

This study investigated the relationships of preschool children's interactive peer play, stimulated home environment, and mother-child interaction. A total of 255 children were selected in this study. Data were analyzed with Pearson correlations and covariance structural analysis by using SPSS and AMOS, a statistical program for structural equation modeling. The major findings of this study were as follows: First, interactive peer play was associated with stimulated home environment and mother-child interaction. Second, the results confirmed the pathway from stimulated home environment via mother-child interaction to interactive peer play showing a significantly good model fit. The paths from stimulated home environment to children's interactive peer play were mediated by mother-child interaction.

본 연구는 기존의 인터넷 및 웹 광고에 대한 연구들을 바탕으로 동영상 UCC 광고에 대한 소비자의 태도와 수용에 영향을 미치는 요인을 분석해 보고자 하였다. 웹 광고 모델에서 사용된 정보성, 오락성, 부정적 자극 이외에 유용성과 용이성, 개인사용자 특성, 플로우, 그리고 인센티브를 새로운 변인으로 추가하였다. 연구 결과에 따르면, 오락성, 부정적 자극, 유용성 및 용이성, 플로우는 동영상 UCC 광고에 유의한 영향을 미치는 것으로 나타났지만, 정보성, 개인사용자 특성, 그리고 인센티브는 그렇지 않은 것으로 나타났다. 플로우는 동영상 UCC 광고의 수용에도 직접적으로 영향을 미치는 것으로 나타났으며, 동영상 UCC 광고에 대한 태도는 수용에 유의한 영향을 미치는 것으로 나타났다.

본 연구는 사건관련전위를 이용하여 정신병질자들이 정서인식에 따른 반응억제의 어려움이 있는지를 알아보기 위해 수행되었다. 교도소에 수용 중인 수형자들을 대상으로 PCL-R(Psychopathy Checklist-Revised)의 점수에 따라 6명의 정신병질 수형자집단과 4명의 정상 수형자집단을 선별하고, 얼굴자극을 이용한 시각 Go/NoGo 과제를 실시하였다. 모든 피험자들은 Go 자극에 버튼을 누르고 NoGo 자극에 버튼을 누르지 않도록 지시를 받았으며, 과제를 실시하는 동안 사건관련전위를 측정하였다. 과제 1에서는 공포표정을 NoGo자극으로 사용하고 중성표정을 Go자극으로 사용하였으며, 과제 2에서는 슬픈 표정을 NoGo자극으로 사용하고 중성표정을 Go자극으로 사용하였다. 정신병질 수형자집단은 공포표정의 NoGo P3 진폭이 중성표정의 Go P3 진폭보다 크게 나타난 반면에 정상 수형자집단은 공포표정과 중성표정 간의 P3 요인의 진폭이 유사하거나 공포표정의 NoGo P3 진폭보다 중성표정의 Go P3 진폭이 더 크게 나타났다. P3 잠재기를 분석한 결과, 정신병질 수형자집단은 슬픔 표정자극의 NoGo조건에서 중성표정자극의 Go조건보다 느린 P3 잠재기를 나타낸 반면, 정상 수형자집단은 NoGo조건에서 Go조건보다 빠른 P3 잠재기를 나타냈다. 정서인식검사결과, 정신병질 수형자집단은 정상 수형자 집단보다 유의미하게 낮은 정확도를 나타냈다. 이러한 결과는 정신병질자들이 공포, 슬픔과 같은 부정적인 정서를 인식한 후에 반응을 억제하는데 인지적인 어려움을 겪는다는 것을 보여준다.

인간의 감성평가 기술은 제품설계에 필요한 중요한 기술로 인식되고있다. 정량적이고 객 관적인 감성평가를 위한 구체적인 연구가 요구된다. 본 연구는 생리신호가 인간감성에 따라 변화한 다는 가정아래 인간 오감(청각, 시각, 후각, 미각, 촉각)에 대한 생리신호 (EEG, ECG, GSR, FEMG)의 변화를 측정하였다. 감각종류로 긍정적 감성과 부정적 감성을 유발할 4개의 자극이 피실험자에게 제시되었고, 모든 생리신호를 동기화하여 측정하였다. 측정된 신호는 통계처리하여 주관적으로 평가한 감성과의 상관성을 분석하였고 긍정적인 감성과 부정적인 감성에 따른 신호변화의 특성을 파악하여 감 성평가를 위한 상관성을 관찰했다.
