  • 본 연구는 피부에 가해지는 직물촉각 자극에 따라 나타나는 정서와 관련된 뇌파특징을 알아보려는 기초연구이다. 실험l에서는 촉각에 의한 정서가 생리적인 측정치를 통해 구분될 수 있는지를 알아보고자, 피험자에게 물리적 특성이 극단적으로 다른 자극을 선택하여 실험을 실시하였다. 20명의 대학생 치험자 (20-25세)에게 자극이 무선적으로 제시되었고, 각 자극제시후 피험자는 제시자극에 대한 느낌을 주관적 정서척도로 평정하였다. 뇌파는 양쪽 귓볼(A1, A2)을 기준전극으로 하여 F3, F4, C3, C4, T4, P3, P4, O1, O2에서 측정되었고, 측정된 뇌파는 FFT방법으로 분석되었다. 각 피험자의 주관적 평가 결과에 따라 가장 쾌한 자극과 가장 불쾌한 자극이 제시되었을 때 측정한 뇌파의 분석결과를 비교하였다. 전두엽, 두정엽, 후두엽 영역에서 쾌자극 제시시에 alpha파가 유의미하게 높은 값을 나타내었고, 후두엽 영역에서 불쾌자극 제시시 beta가가 유의미하게 높게 나타났다. 물리적 특성이 유사한 다섯 가지 직물자극을 가진 실험 ll에서와 유사한 절차에 다섯 가지 직물자극을 가진 실험 1에서와 유사한 절차에 의해 실험ll가 실시되었다. 실험l의 결과에 근거하여 측정 부위를 F3, F4, P3, P4, O1, O2로 축소되었다. 쾌자극 제시시의 뇌파는 불쾌자극 제시시보다 slow alpha(8-10Hz)파의 출현량이 많은 반면, slow beta(13-20Hz)파의 출현량은 적었다. 결론적으로 직물촉각자극에 의해 유발되는 심리적 반응에 특정적인 뇌파반응이 존재하며, 이는 촉각에 의해 유발되는 주관적인 쾌.불쾌정서를 객관적으로 측정하기 위한 지표로서 뇌파특징을 사용할 수 있음을 의미한다.

  • 이 연구의 목적은 IAPS(국제정저사진체계) 사진자극에 의해 유발된 각각의 주관적 정서상태에 특정적인 자율신경계 반응이 존재하는지를 규명하는 것이다. 부정적 정서(분노, 슬픔, 놀람)와 긍정적 정서(행복, 흥분)를 유발하는 IAPS사진을 각 60초 동안 제시하였을 때 유발되는 심박률, 호흡률, 피부전도반응을 측정하였다. 시각자극이 주어진 초리 30초 동안 통계적으로 유의미한 심박률 감속 및 호흡률 감소를 보여주었으며, 뚜렷한 피부전도반응이 출현하였다. 심박률 감속은 혐오보다 흥분에서 더 크게 나타났고, 피부전도반응의 진폭은 혐오보다 흥분에서 더 큰 것으로 나타났다. 한편, 피부전도반응의 진폭이 상승하는 시간은 슬픔, 행복, 놀람보다 혐오에서 더 짧아지는 경향을 보여주었다. 이와 같은 자율신경계 반응(심박률, 호흡률, 피부전도반응)은 정서상태간에 뚜렷한 차이를 보여주며, 특정 정서상태에서 자율신경계 반응은 개인차가 있기는 하지만 전체적으로 매우 전형적인 반응패턴을 보여주었다. 본 연구의 결과는 정서 특정적인 자율신경계 반응이 존재할 가능성을 시사해주며, 생리신호분석을 통해서 심리적 정서를 결정할 수 있는 형판(template)의 구성을 위해서 다양한 자율신경계 정서반응의 지표를 포괄적으로 측정 분석하는 후속연구가 요구된다.

  • This study investigated the effects of mild mental imagery inducing pleasantness or unpleasantness and cognitive mental arithmetic task on skin conductance level. Subjects were f undergraduates(male 5, female 4). They were given the list of the words and asked to write down the liked objects and the disliked ones freely associated with these words. Among these objects the most-liked one and the most disliked one were selected as the self-induced mental imageries. Data-collection procedures were as follows ; first baseline, pleasant imagery, 2nd baseline, unpleasant imagery, finally 3rd baseline, and mental arithmetic task subtracting continuously 7 from the number 500. During these trials, the SCLs were recorded every 10 seconds. The results indicated that there were nonsignificant differences between the 3 trial-baselines ot each condition. This suggested that unlike the procedures used in the previous studies, our procedures would give the stability of the baseline level necessary for the comparison of the effects of several stimuli. Also, the level of skin conductance in mental arithmetic condition was significantly higher than that of the emotional mental imagery. This suggested the possibility that mental arithmetic task would gave rise to the higher physiological arousal in comparison to mental imageries. Overall, it was suggested that the procedures and the stimulus presentation methods used in this preliminary study could be useful for the data-collection techniques for The future study. Implications for the future study were presented.

  • This study analyzes the Soju(Korean alcohol) advertisement image, which is relatively easy to interpret subjectively, among sexual appeal advertisements that stimulate consumers' curiosity, where the image is verified through AOI (area of interest) 3 areas (face, body, product), and eye-tracking, one of the psychophysiological indicators. The result of the analysis reveals that visual attention, the interest in the advertising model, was higher in the face than in the body shape. Contrary to the prediction that men would be more interested in body shape than women, both men and women showed higher interest in the face than a body. Besides, it was derived that recognition and recollection of the product were not significant. This study is significant in terms of examining the pattern of visual attention such as the gaze point and gaze time of male and female consumers on sexual appeal advertisements. In further, the study looks forward to bringing a positive influence to the soju advertisement image by presenting the expression method that the soju advertisement image should pursue as well as the appropriate marketing direction.

  • Objectives: Domestic violence is related to many psychiatric diseases, such as depression, anxiety disorder, and PTSD. Heart rate variability (HRV) is an index of autonomic control of the heart and is related to cardiovascular and emotional disorders. Although there have been some studies on the effects of domestic violence on women's mental health, relatively little information is available on HRV in this population. The aim of this study is to investigate demographic data, psychological features, and HRV in female victims of domestic violence and difference between Korean and foreign female victims. Methods: A total of 210 female victims of domestic violence (166 Korean women and 44 foreign women) were recruited for this study. Psychological symptoms were measured using the Hamilton Rating Scale for Anxiety (HAM-A), Hamilton Rating Scale for Depression (HAM-D), and Impact of Event Scale-Revised (IES-R). HRV measures were assessed by time-domain and frequency-domain analyses. Results: The mean score of HAM-A was 13.81, that of HAM-D was 12.92, and that of IES-R was 33.61 ; there were no significant differences between Korean and foreign women in these measures. In HRV time domain analyses, approximate entropy (ApEn) was significantly increased in foreign women compared to the Korean women. The square root of the mean of the sum of the squares of differences between adjacent NN intervals (RMSSD) was significantly decreased in foreign women compared to Korean women. There were no significant differences in the other HRV variables between Korean and foreign women. Conclusion: Female victims of domestic violence in Korea are associated with depression, anxiety, and PTSD symptoms. The physiologic factors of a female victim's nationality could be related to higher ApEn and lower RMSSD in foreign female victims. These findings have important implications for future study to study the relationships among ethnic and environmental factors and HRV variables.

  • The noise of MRI shooting is 100dB loud and has an intensive psychological and physiological influences on the human body. ECG signals were measured by experimental methods, while wearing earplugs for 15 minutes in the stable state. Then the ECG signals were measured for 30 minutes while listening to about 100dB of sound in a MRI equipment. In this study, the heart rate variability of men and women was analyzed according to the MRI noise stress level through the frequency analysis. As the MRI noise level is about 100dB, HRV analysis resulted in an imbalance between the sympathetic and parasympathetic. During the period from the resting state up to 10 minutes, the maximum stress state was shown. This study will encourage MRI workers to take interests in hearing protection for the patient and to make objective indicators about MRI noises.
