Electrodermal Activity as an Indicator of Emotional Processes

Boucsein, Wolfram Korean Society for Emotion and Sensibility 1999 감성과학 Vol.2 No.1

The differentiation of emotions by means of psychophysiological measures has been only moderately successful so far. A major reason for this dilemma may be the lack of appropriate neurophysiological modeling for the various autonomic nervous system based measures being used in emotion research. The aim of the present article is to provide such a neurophysiological background for electrodermal activity which has been frequently used as an indicator of emotional processes. First, the literature is reviewd with respect to the usability of electrodermal measures as an indicators of emotion. second, the neurophysilogical sources of electrodermal phenomena in general are described. Electrodermal activity has different origins in the central nervous system, a limbic-hypothalamic source that dominates during negative emotions as opposed to a premotor and basal ganglia source being predominantly active during positive emotions. Panksepp's model of four basic emotive systems is adopted for demonstrating subcortical structures and pathways possibly involved in the elicitation of both kinds of electrodermal activity in comparison with cardiovascular in dicators of emotional processes.

Anterior Cingulate Cortex and Amygdala Dysfunction Among Patients with Alcohol Dependency During Exposure to Negative Emotional Stimuli

Park, Mi-Sook Korean Society for Emotion and Sensibility 2018 감성과학 Vol.21 No.4

This study aimed to identify specific psychological and brain activation responses relating to the processing of negative emotions in patients with alcohol dependency. The authors hypothesized that patients with alcohol dependency would demonstrate the abnormal functioning of brain regions involved in negative emotions. Eleven male patients diagnosed with alcohol dependence in an inpatient alcohol treatment facility and 13 social drinkers with similar demographics were scanned using functional magnetic resonance imaging (fMRI) as they viewed film clips that evoked negative emotions. During exposure to negative emotional stimuli, the control group evinced significantly greater activity in the right anterior cingulate cortex (ACC) in comparison to patients with alcohol dependency. Correlation analyses demonstrated a negative association in the relationship between beta values from the right ACC and amygdala in participants classified in the control group. No statistically significant relationship was observed for blood oxygenation level-dependent (BOLD) changes between the two regions in the patient group during the elicitation of negative emotions. On the other hand, patients exhibited a greater activation of the amygdala as negative emotions were induced. These results suggest that alcoholism presents pathophysiology of brain activation that is distinct from the responses of healthy individuals functioning as controls.

Differences in Large-scale and Sliding-window-based Functional Networks of Reappraisal and Suppression

Jun, Suhnyoung,Lee, Seung-Koo,Han, Sanghoon Korean Society for Emotion and Sensibility 2018 감성과학 Vol.21 No.3

The process model of emotion regulation suggests that cognitive reappraisal and expressive suppression engage at different time points in the regulation process. Although multiple brain regions and networks have been identified for each strategy, no articles have explored changes in network characteristics or network connectivity over time. The present study examined (a) the whole-brain network and six other resting-state networks, (b) their modularity and global efficiency, which is an index of the efficiency of information exchange across the network, (c) the degree and betweenness centrality for 160 brain regions to identify the hub nodes with the most control over the entire network, and (d) the intra-network and inter-network functional connectivity (FC). Such investigations were performed using a traditional large-scale FC analysis and a relatively recent sliding window correlation analysis. The results showed that the right inferior orbitofrontal cortex was the hub region of the whole-brain network for both strategies. The present findings of temporally altering functional activity of the networks revealed that the default mode network (DMN) activated at the early stage of reappraisal, followed by the task-positive networks (cingulo-opercular network and fronto-parietal network), emotion-processing networks (the cerebellar network and DMN), and sensorimotor network (SMN) that activated at the early stage of suppression, followed by the greater recruitment of task-positive networks and their functional connection with the emotional response-related networks (SMN and occipital network). This is the first study that provides neuroimaging evidence supporting the process model of emotion regulation by revealing the temporally varying network efficiency and intra- and inter-network functional connections of reappraisal and suppression.

Lim, Joa-Sang,Whang, Min-Cheol Korean Society for Emotion and Sensibility 1998 감성과학 Vol.1 No.2

컴퓨터 기술이 급속도로 발전함에도 불구하고 사용자의 감성에 반응하는 컴퓨터는 아직 등장하지 않고 있다. 그 결과 사용자는 컴퓨터 작업 과정에서 발생할 수 있는 부정적 감성에 무방비로 노출되어 있으며, 이는 컴퓨터 작업의 효과적 수행을 저해하게 될 것이다. 본 논문은 사용자의 감성이 컴퓨터 작업에 미치는 영향을 고찰하였으며, 이를 통해 감성 컴퓨터의 개념적 구조를 제안하였다. 본 연구에서 제안한 감성 컴퓨터란 사용자 감성의 변화를 포착하고, 부정적 변화에 대응하도록 설계된다. 또한 본 연구에서는 감성 컴퓨터의 구축에 필요한 세 가지 요소, 즉 감성의 측정 및 평가, 신호 처리, 사용자 인터페이스를 중심으로 향후 연구 과제를 도출하였다. 아직 감성 컴퓨터에 대한 연구가 초기 단계인 점을 감안하면, 이에 관한 체계적인 연구가 시급한 실정이다.

Neuroaesthetics: A Concise Review of the Evidence Aimed at Aesthetically Sensible Design

Choi, Yun Jung,Yoon, So-Yeon Korean Society for Emotion and Sensibility 2014 감성과학 Vol.17 No.2

In recent years, advancing technology and growing interest in neuromarketing and neurobranding have led to foundational research that facilitates a better understanding of consumers' affective responses and unconscious information processing. However, the areas of aesthetics and design have remained largely unaffected by such advances and implications. The purpose of this study is to present a systematic review of the neuroscientific evidence aimed at sensible design for design and marketing researchers interested in exploring neuroaesthetics, an interdisciplinary area by nature. Sciencedirect, EBSCO, and the Google Scholar database were searched in February 2014 to select and review previous studies of aesthetics involving neuroscience. Twenty-eight studies were reviewed and divided into two categories: reward system and emotion. In addition to discussions on previous approaches, future research directions focusing on the process of aesthetic judgments (e.g., design elements, marketing stimuli) are proposed.

A Study on Product Development to Promote the Effects of Exercise on Children and to Induce Their Interest in Exercise: A Survey on the Development of Cognitive and Motor Functions in Children

Cho, Hyun-Seung,Yang, Jin-Hee,Jung, Chan-Woong,Lee, Joo-Hyeon Korean Society for Emotion and Sensibility 2017 감성과학 Vol.20 No.1

This study was conducted to develop wearable products with visual and auditory feedback aimed at promoting exercise interest in children. Here we determined the theoretical characteristics of cognitive and motor function development during childhood, empirical characteristics of children's motor functions, and factors that encourage exercise using natural observation and in-depth interview research methods. The questionnaire assessed children's motor ability, intensively trained body parts in sports programs, types of training or classes that improve the motor ability of each muscle group, significantly considered aspects of children's sports programs, and factors that promote children's interest in exercise. Our results suggest that the development of sport programs comprising varied exercise options that enhance body and limb movements are needed for balanced growth. Furthermore, it is very important to provide motivation for regular exercise and appropriate feedback, such as praise and encouragement, to maintain interest in exercise. This study identifies the standards for developing products that peak children's interest in exercise and the basis for a physically and mentally healthy society.

Emotional Evaluation about Physico-chemistry Laboratory Equipment's Exterior Design

Kim, Hyung-Soon,Lee, Han-Sung,Jeong, Sang-Hoon Korean Society for Emotion and Sensibility 2012 감성과학 Vol.15 No.2

Laboratory equipment will continue to be developed and created as long as experiments continue. Up until now, the designs have been focused on the functional role; successfully process the study purpose. However, nowadays, the requirements of providing emotional satisfaction of the design, has increased. Even so, the users are normally limited by specific groups and investments on these designs have been neglected due to small annual production by the small market. Through this study, we have conducted an emotional evaluation on Temperature and Humidity Chamber's (TH Chamber) exterior shape. First of all, we extracted emotional words and placed them in categories that represent these emotions and conducted an emotional evaluation on four typical TH chamber models. They were selected based on its door lock type and control box type. The result showed that the 'fixed type' of control box and the 'handle type' of door lock were most favorable by the users, satisfying the five representative emotions; 'Attractiveness', 'Classiness', 'Comfortableness', 'Pleasant' and 'Satisfaction in Usability'. Particularly, all 4 emotional words in the 'Satisfaction in Usability' category recorded over 3.65. This indicates that Satisfaction in Usability is relatively an important category when expressing laboratory equipment. The result of this research is expected to be used as a basic data to find a way of right approach in laboratory equipment design.

Emotion Detecting Method Based on Various Attributes of Human Voice

MIYAJI Yutaka,TOMIYAMA Ken Korean Society for Emotion and Sensibility 2005 감성과학 Vol.8 No.1

This paper reports several emotion detecting methods based on various attributes of human voice. These methods have been developed at our Engineering Systems Laboratory. It is noted that, in all of the proposed methods, only prosodic information in voice is used for emotion recognition and semantic information in voice is not used. Different types of neural networks(NNs) are used for detection depending on the type of voice parameters. Earlier approaches separately used linear prediction coefficients(LPCs) and time series data of pitch but they were combined in later studies. The proposed methods are explained first and then evaluation experiments of individual methods and their performances in emotion detection are presented and compared.

The Effects of Color Hue-Tone on Recognizing Emotions of Characters in the Film, Les Misérables

Kim, Yu-Jin Korean Society for Emotion and Sensibility 2015 감성과학 Vol.18 No.1

This study investigated whether people experience a correspondence between color hue-tone and the main characters' emotions in the 2012 British musical drama film, Les $Mis\grave{e}rables$ through three practical experiments. Six screen images, which represent the characters' different emotions (Parrot's six primary types including love, joy, surprise, anger, sadness, and fear) were selected. For each screen image, participants were asked to judge the degree of the character's dominant emotions evoked from 17 varied screen images, which consisted of original chromatic and achromatized images as well as 15 color-filtered images (5 hues X 3 tones of the IRI color system). These tasks revealed that a chromatic color scheme is more effective to deliver the characters' positive emotions (i.e. love and joy) than an achromatic one. In addition, they proved that the hue and tone dimensions partially influence the relationships between the character emotions and colors.

PARK Oh-Soon,NONAKA Takaka,NISHIWAKIA Tsuyoshi,MAEKAWA Zen-ichiro,MORIMOTO Kazunari,KUROKAWA Takao Korean Society for Emotion and Sensibility 2005 감성과학 Vol.8 No.1

Because hand-written characters, especially drawn by a brush can give readers various impressions, they are not only a communication method but also art works. Authors have already investigated the relationship between brush motion analytical results and sensory testing results obtained from Japanese hiragana and reported quantitative evaluation method for the beauty of hiragana, In this paper, sensory tests for South Koreans who cannot recognize the word are carried out, compared with sensory testing results of Japanese. The evaluation objects are 6 hiragana drawn by 4 beginners and 2 experts, Semantic Differential Method based on 30 paired evaluation words are used in the sensory tests. Therefore South Koreans also feel the beauty in hiragana drawn by experts, as compared with by beginners. On the other hand it was confirmed that South Koreans couldnt recognize the difference among beginners. Judging from the factor analysis results, both Japanese and South Koreans selected stability as the 1st factor, there is interesting difference in the following orders.
