A review of recent studies indicates that positive emotions help buffer stress. In particular, humor is what only human can appreciate. Humor plays an important role in many facets of human life including psychological, social, and somatic functioning. This study is to identify children's ANS responses by humor or joy using audio-visual film clips. 49 male and female children (12-13 years) participated in this study. The participants were briefed on the experiment was its procedure. During the experiment, electrodes were attached to participant and middle fingers of left hands. Physiological responses(EDA, SKT, PPG and ECG) were measured for 30s both in the resting state and experiment state during which emotion provoking stimulus was presented for 2 min. Also, self-report on emotions was followed for 1 min. Results from the self-report showed that both humor and joy were evoked effectively among 89.3% of children. It explains that emotion-eliciting stimuli were effective and appropriate. ANS responses in both emotion were significant in three physiological variables (i.e., SCL, NSCR, LF). There was a significant difference between humor emotion and joy emotion, and both emotions were distinguishable by a specific ANS response pattern.

정서인식분야에서 현재 활발히 연구되고 있는 방법은 다양한 생체신호를 통해 인간의 감정을 인식하는 것이다. 생리심리학적 연구에서 인간의 감정상태와 생체반응은 강한 상관이 있다고 알려져 있다. 생체신호는 센서 등으로 비교적 간단하게 획득할 수 있으며, 이를 이용한 감정인식은 사회적, 문화적인 차이에 덜 민감하므로 최근에 주목 받고 있다. 본 연구에서는 audio-visual film clips 자극으로 기쁨, 분노, 놀람, 스트레스 4종류의 정서를 유발하고 그에 대한 반응으로써 생체신호를 측정하였다. 그리고 생체신호로부터 feature를 추출하였고, 주성분분석(PCA)로 특징 축소를 수행하였다. 4가지 정서를 분류 한 결과, 9명의 가우시안 프로세스 분류기에 의한 평균 정서 판별율은 64.85 % (57.14~70.0)의 결과를 얻었다.

This study investigates happy life experiences and their emotional responses to these experiences with a sample of Korean students and adults. A total of 489 Korean university students and adults completed an open-ended questionnaire developed by the present researchers. Three sets of results have been found. First, while experiences of achievement and failure affect the strength of feelings of happiness or unhappiness, social relationships with family members and friends affect the frequency of feelings of happiness or unhappiness. Second, while strong positive affects are aroused by sense of achievement and pride, frequent positive affects are aroused by feeling of calmness and positive relational emotions (such as Jung - deep affection and attachment). Third, while strong negative affects are aroused by sense of frustration and sadness, frequent negative affects are aroused by anxiety and negative relational emotions (such as the sense of indebtedness and shame). These results indicate that the interpersonal relationships with family members and friends and personal achievements and failures influence the subjective well-being of feeling happy or unhappy with people's lives.

This study was conducted to investigate children's emotional response, emotion regulation strategy, and emotion regulation effect (regulation effect of strategies), and to determine the relationships among emotion regulation strategy, emotion regulation effect and children's psychological well-being in anger, (ear, and disappointment situations. Emotion regulation strategy recomposed four strategies through factor analysis based on the children's direct answers to the question inquiring on the method used to regulate anger, fear, and disappointment. A total of 359 elementary school children in glades 5 or 6 selected one strategy use to regulate anger, fear, and disappointment. The effect of that selected strategy were estimated. Psychological well-being is evaluated by a questionnaire. The results of this study showed that most of elementary school children used the attention evocation strategy to regulate anger, fear, and disappointment, and this strategy was confirmed to be the most effective. Children's psychological well-being was associated with only emotion regulation effect in anger, fear, and disappointment situations.

There have been many studies on patients who suffer from anxiety disorders. However, there is been not enough attention on the difference in the level of between the two populations with and without anxiety disorders. This study was performed to investigate the difference in the ANS responses induced by fear in children. Experimental procedures were as follow: All subjects were in upper grade levels in elementary school. ANX(anxiety) scales of PIC(Personality Inventory for Children) were used to measure fear anxiety. Audio-visual clips were used as stimulus to provoke fear emotion. Baseline of physiological signals, ECG, PPG, EDA, and SKT, were measured for 30 seconds before the fear stimulus. Physiological signals were then recorded for 2 minutes while fear is evoked. Psychological and physiological responses were analyzed. All the children reacted to the fear stimulus with high intensity of fear. Physiological responses showed that SKT, SCR, NSCR, HR, RSA, RESP, HF were increased, while R-R was significantly decreased, respectively, during the period of fear induction. Analysis of the level of anxiety and the physiological responses produced by the experience of fear revealed a statistically significant positive correlation in SKT, HR, and RSA. In other words, the higher the level of anxiety, the higher the levels of SKT, HR, and RSA when children experienced fear in conclusion, it is confirmed through this research that physiological responses to fear is associated with the level of anxiety each individual.

Tn the present study, 9 photographs from the International Affective Picture System (IAPS) judged to express best 2-dimensional sensibility were selected and used to stimulate the subjects. The goal of the study lay in verifying whether or not the consequent affective changes in the subjects can be discriminated psychologically and physiologically in terms of arousal and relaxation. In order to determine affective changes, the physiological signals of the subjects' autonomic nervous system were measured through electrocardiogram (ECG) , galvanic skin response (GSR), skin temperature, and respiration. After stimulation and measurement, subjective evaluation was conducted. Subjective evaluation revealed that affective arousal level could be classified into 4 consecutive stages: arousal 〉 unpleasant arousal, pleasant arousal 〉 comfort 〉 relaxation. Analysis revealed that the responses of the autonomic nervous system, too, could be classified into 3 consecutive stages: arousal, unpleasant arousal, pleasant arousal 〉 comfort 〉 relaxation. By selecting and using 9 photographs from the IAPS deemed best to express Koreans'2-dimensional sensibility, the present study confirmed that it is possible to discriminate changes in the subjects' affective arousal level in terms of arousal and relaxation through psychological and physiological evaluation.
