The affective primacy hypothesis of Murphy와 Zajonc(1983) was replicated in this study. The results of experiment 1 and 2 expanded the affective priming effect by facial valence as well as affective events on object rating. Experiment 3 explored the affective priming effect of schizophrenics at the supraliminal level and their results compared with those of normal subjects. For normal subjects the effect of affective priming was found only at the subliminal level but schizophrenics showed the assimilation effects by affective priming even at the supraliminal level. Finally. principles of affective processing were discussed.

In this study, we assessed how participants represent various sensory stimuli experiences through behavioral ratings and physiological measurements. Utilizing intersubject correlation (ISC) analysis, we evaluated whether individuals' affective responses of dominance, arousal, and valence differed when stimuli of three modality conditions (auditory, visual, and haptic) were presented. ISC analyses were used to measure the similarities between one participant's responses and those of the others. To calculate the intersubject correlation, we divided the entire dataset into one subject and all other subject datasets and then correlated the two for all possible stimulus pair combinations. The results revealed that for dominance, ISCs of the visual modality condition were greater than the auditory modality condition, whereas, for arousal, the auditory condition was greater than the visual modality. Last, negative valence conditions had the greater consistency of the participants' reactions than positive conditions in each of the sensory modalities. When comparing modalities, greater ISCs were observed in haptic modality conditions than in visual and auditory modality conditions, regardless of the affective categories. We discussed three core affective representations of multiple modalities and proposed ISC analysis as a tool for examining differences in individuals' affective representations.

정서 전달에는 언어적 의사소통뿐만 아니라 비언어적 의사소통이 거론되곤 한다. 하지만 지금까지의 비언어적 의사소통 연구는 대부분 언어의 음향학적 연구나 얼굴표정 연구에 국한되었다. 또한 음악의 정서에 대한 연구는 음악적 구조 혹은 스타일과 여러 성격적 특질 및 행동 간의 관계, 혹은 생리적 효과 등 어떤 음악(what music)이 특정한 효과를 일으키느냐에 중점을 두고 있었다. 따라서 본 연구에서는 Gabrielsson & Juslin(1996)의 연구에 의거, 음악을 통하여 작곡가가 아닌 연주자의 의도된 정서가 청자에게 얼마나 잘 지각될 수 있는지 알아보고자 하였다. 봉 녕구의 가설은 다음과 같다; 첫째, 연주자의 정서적 의도는 음악의 모든 물리적 변인에 영향을 준다; 둘째, 청자는 의도된 정서를 지각하는 데 일반적으로 성공적이다; 셋째, 특정 정서는 다른 정서보다 더 잘 구분된다. 본 연구에 사용된 곡은 학습 효과를 배제하기 위하여 새롭게 전문 작곡가에 의해 작곡되었으며, 전문 연주자는 동일한 곡을 7종류의 정서(행복한, 슬픈, 화난, 두려운, 다정한, 엄숙한, 정서 표현 없음)를 표현하도록 연주하였다. 하나의 완전한 음악을 표현하기 위하여 각 곡은 멜로디(악기구성: 일렉트릭 기타, 베이스, 그랜드 피아노)와 리듬(드럼)을 포함하였다. 실험참가자는 각 곡을 듣고 7개의 정서 종류 각각에 점수를 평정하였다. 그 결과 이전 연구와 마찬가지로 청자는 연주자의 의도된 정서를 일반적으로 지각하는 데 성공하였으며 7개의 정서 중 특징적인 정서("행복한", "슬픈", "화난", "다정한") 는 다른 정서 보다 더 잘 구별되었다. 본 연구에 사용된 "두려운" 정서 곡의 음향분석 결과 소리 강도의 큰 변산이 특징이었다. 이는 이전 연구에서 "두려운" 정서의 특징인 타이밍의 큰 변산과 함께, "두려운" 정서가 '불규칙적이거나 변화가 커서 예측하기 어려운' 속성을 지니고 있음을 시사한다. 또한 "다정한" 정서에 대해서 본 연구에서는 다른 모든 정서와 유의미한 차이를 보인 반면, 이전 연구에서는 "슬픈"과 유의미한 차이가 없었다. 이는 본 연구에 쓰인 "다정한" 정서의 곡은 리듬 패턴을 다른 정서 버전과는 다르게 보사노바 리듬을 사용하였다. 이전 연구와는 다르게 빠른 템포였음에도 불구하고 구별이 잘 된 이유는 이와 같이 장르 특징적인 영향이 컸기 때문이라고 할 수 있다. 이는 연주자나 음악 스타일 자체의 성격이 정서 판단에 있어 큰 영향을 준다는 사실을 시사한다. 종합적으로 음악을 통한 정서 전달에 있어 연주자, 청자, 악기, 음악 스타일의 차이가 영향을 줄 수 있다는 사실을 확인하였으며 이러한 결과는 Scherer & Oshinsky(1977)가 언급하였듯 음악 연주가 다른 비언어적 의사소통 방법과 공유하는 특징이 있음을 시사한다.

인간의 정서를 분류하려는 노력은 오래전부터 있어왔다. 시각 및 청각 자극을 사용한 심리생리적 정서연구는 최근에 들어 활발하게 이루어지고 있으나, 촉각 자극을 사용한 정서연구는 찾아보기 힘들다. 본 연구는 피부에 가해지는 다양한 자극에 따라 나타나는 정서와 관련된 뇌파특징을 측정하고자 하는 기초연구이다. 물리적 특성이 다른 다섯가지의 직물자극을 20명의 대학생 피험자(20-25세)에게 무선적으로 제시하였다. 각 자극의 제시시간은 1분이었으며, 자극간 간격은 3분이었다. 각 자극제시후 매자극후 피험자는 제시자극에 대한 느낌을 주관적 정서척도로 평정하였다. 뇌파는 양쪽 귓볼(A1, A2)을 기준전극으로 하여 좌.우반구의 전두엽(F3, F4), 두정엽(P3, P4), 후두엽 (O1, O2)에서 측정되었고, 측정된 뇌파는 FFT방법으로 분석되었다. 각 피험자의 주관적 평가의 결과에 따라 가장 쾌한 자극과 가장 불쾌한 자극이 제시되었을 때 측정한 뇌파의 분석결과를 비교하였다. 쾌자극 제시시의 뇌파는 불쾌자극 제시시보다 slow alpha(8-10Hz)파의 출현량은 적었다. 결론적으로 직물촉각자극에 의해 유발되는 심리적 반응에 특정적인 뇌파반응이 존재하며, 이는 촉각에 의해 유발되는 주관적인 쾌.불쾌정서를 객관적으로 측정하기 위한 지표로서 뇌파특징을 사용할수 있음을 의미한다.

The snake detection theory posits that, due to competition with snakes, the primate visual system has been evolved to detect camouflaged snakes. Specifically, one of its hypotheses states that the subcortical visual pathway mainly consisting of koniocellular cells enables humans to automatically detect the threat of snakes without consuming mental resources. Here we tested the hypothesis by comparing human participants' responses to snakes with those to fearful faces and flowers. Participants viewed either original images or converted ones, which lacked the differences in color, luminance, contrast, and spatial frequency energies between categories. While participants in Experiment 1 produced valence and arousal ratings to each image, those in Experiment 2 detected target images in the breaking continuous flash suppression (bCFS) paradigm. As a result, visual factors influenced the responses to snakes most strongly. After minimizing visual differences, snakes were rated as being less negative and less arousing, and detected more slowly from suppression. In contrast, the images of the other categories were less affected by image conversion. In particular, fearful faces were rated as greater threats and detected more quickly than other categories. In addition, for snakes, changes in arousal ratings and those in bCFS response times were negatively correlated: Those snake images, the arousal ratings of which decreased, produced increased detection latency. These findings suggest that the influence of snakes on human responses to threat is limited relative to fearful faces, and that detection responses in bCFS share common processing mechanisms with conscious ratings. In conclusion, the current study calls into question the assumption that snake detection in humans is a product of unconscious subcortical visual processing.

The purpose of this study was to develop the Empathy Rating Scale by a third party and examine the validity of the scale. Based on the results of the pilot study, the study 1 focused on developing Empathy Rating Scale by a third party. From the exploratory factor analysis on a total of 15 preliminary items, three fators had been derived: 'Beginning of empathy', 'Process of empathy', 'Result of empathy'. The study 2 identified its validity by confirmatory factor analysis, correlation analysis, and discriminant analysis. Those three factors indicated the reasonable fit index by confirmatory factor addition, this scale identified a significant positive relation with authenticity, emotional clarity, and intimacy. On the other hand, it indicated a negative relation with anxiety attachment and rejection attachment. Therefore, the results indicated that this scale on a total of 11 item has a reliable convergent validity. Finally, implication and limitation of this study were discussed in relation with future studies.

This study examined effects of gender and empathic emotional expression of an anthropomorphic interface agent on users. assessment of the agent. In addition, it examined effects of gender and emotional expression regardless of whether visual fidelity of the agent. In Study 1, The agents were manipulated by photographs of human face. The agent expressed empathic emotion by making an other-oriented emotional response congruent with another's perceived welfare. Subjects participated in a task with the agent and then they assessed the agent by rating interpersonal assessment scale. The result reported their preference to the female agent. In addition, they tended to make positive assessment to the agent of opposite gender. In the study 2, gender and expressed emotion of the agent with low fidelity was manipulated. Subjects participated in a task with the agent and then they assessed the agent by rating the same interpersonal assessment scale as study 1. The result reported their preference to the female agent. In addition, they preferred the agent expressing empathic emotion to the agent expressing self-oriented emotion or no emotion. Though the agent had low visual fidelity, its gender and expressed empathic emotion could make a significant effect on users' assessment.

This study used intersubject representational similarity analysis (IS-RSA) to identify participant-response consistency patterns in previously published data. Additionally, analysis of variance (ANOVA) was utilized to detect any variations in the conditions of each experiment. In each experiment, a combination of ASMR stimulation, visual and auditory stimuli, and time-series emotional video stimulation was employed, and emotional ratings and physiological measurements were collected in accordance with the respective experimental conditions. Every pair of participants' measurements for each stimulus in each experiment was correlated using Pearson correlation coefficient as part of the IS-RSA. The results of study revealed a consistent response pattern among participants exposed to ASMR, visual, and auditory stimuli, in contrast to those exposed to time-series emotional video stimulation. Notably, the ASMR experiment demonstrated a high level of response consistency among participants in positive conditions. Furthermore, both auditory and visual experiments exhibited remarkable consistency in participants' responses, especially when subjected to high arousal levels and visual stimulation. The findings of this study confirm that IS-RSA serves as a valuable tool for summarizing and presenting multidimensional data information. Within the scope of this study, IS-RSA emerged as a reliable method for analyzing multidimensional data, effectively capturing and presenting comprehensive information pertaining to the participants.

Previous studies on texture and emotion have focused on identifying precisely which tactile stimuli trigger specific emotions. Despite the significant role of vision in tactile perception, research has so far only focused on the singular aspect of texture. In this study, we used tactile stimuli to investigate the effects of three variables-roughness, hardness, and visual blocking-on the affective responses to tactile perception. The experimental stimuli that can be encountered in daily life were selected based on the four conditions of "rough/hard," "rough/soft," "smooth/hard" and "smooth/soft" by crossing two roughness conditions (rough, smooth) and two hardness conditions (hard, soft). The experiment was divided into two sessions depending on whether or not visual blocking existed. Participants completed a session in which they evaluated a tactile stimulus after touching it without seeing it and then proceeded with a session in which they evaluated a stimulus after touching it with sight of it. The results of the repeated-measures ANOVA showed that individuals reported a more positive perception when touching stimuli with visual cues and more negative when touching stimuli without visual cues. Furthermore, the inclination to perceive smooth and soft stimuli more positively and rough stimuli more negatively was stronger when touching without visual cues. The results of this study suggest implications for enhancing the understanding of the interaction between emotion and visual information processing by elucidating how emotions are experienced differently in situations where visual information is provided and where it is not.
