Autonomic and EEG responses were analyzed in 32 college students exposed to visual stimulation with Korean Affective Picture System (KAPS) and 36 students exposed to the International Affective Picture System (IAPS). Cardiac, electrodermal, and electrocortical measures were recorded during 30 sec of viewing affective pictures. The slides intended to elicit basic emotions (fear, anger, surprise, disgust, and sadness) were presented to subjects via Kodak slide-projector. The aim of the study was to differentiate autonomic and EEG responses associated with the same negative valence emotions elicited by KAPS and IAPS stimulation and to identify the influence of cultural relevance on physiological reactivity. The analysis of obtained results revealed significant differences in physiological responsiveness to emotionally negative valence slides from KAPS and IAPS. The typical response profile for all emotions elicited by the KAPS included HR acceleration (except surprise), and increase of electrodermal activity, slow and fast alpha blocking and fast beta power increase in EEG, which was not associated with significant asymmetry (except fast alpha in sadness). Stimulation with the IAPS evoked HR deceleration, specific electrodermal responses with relatively high tonic electrodermal activation, alpha-blocking and fast beta increase, and was accompanied also by theta power increase and marked frontal asymmetry (e.g., fast beta, theta asymmetries in sadness, fast alpha in fear). Physiological responses to fear and anger-eliciting slides from the IAPS were significantly less profound and were accompanied by autonomic and EEG changes more typical for attention rather than negative affect. Higher cardiovascular and electrodermal reactivity to fear emotion observed in the KAPS, e.g., as compared to data with the IAPS as stimuli, can be explained by cultural relevance and higher effectiveness of the KAPS in producing certain emotions such as fear in Koreans.

The purpose of this study is to investigate the difference of the response to fashion ad and its effect between traditional ad and postmodern ad, to examine the difference of the response to fashion ad and its effects according to sensation seeking tendency, and to investigate the effect of the response to fashion ad on its effect. For the purposes of this study, two postmodern ads and one traditional ad were selected as stimuli and data were collected from 230 female college students. The results are as follows: 1) Postmodern advertisement was unique, impacting, hard-to-understand, sensory-stimulating, and fantastic, when compared to traditional advertising. 2) Consumers felt disgusted by confusion and shock coming from postmodern advertising, but at the same time, recognized its value as an advertisement and took more pleasure and fun from it. 3) Consumers with high sensation-seeking-tendency perceived postmodern ads more sensually and showed more positive response to the postmodern ads. 4) While subjective, emotional response affected the attitude toward advertisements, sensory-stimulating affected the attitude toward brand and purchase intention. Thus, cognitive response should also be considered significant to form brand equity in long term.

이전 정서연구에서는 다양한 정서유발자극을 이용한 정서 차원 연구들을 통해 쾌불쾌 차원(valence)과 각성 차원(arousal)이란 두 가지의 핵심정서(core affect) 차원을 밝혔다. 최근 등장한 ASMR은 심리적 안정감, 편안함 등의 정서를 유발하는데, 이런 새로운 자극 또한 핵심정서차원에 위치하는지, 사람들에게 일으키는 정서표상은 어떤 양상을 보이는지 확인하고자 하였다. 본 연구는 3가지 정서유형(부정, 중립, 긍정)으로 구분한 ASMR 영상을 자극으로 사용하였다. 연구1에서는 청각 ASMR, 연구2에서는 청각 및 시청각 ASMR을 자극으로 사용하였고, 각 자극마다 10가지의 형용사에 대해 5점 리커트 척도로 정서경험을 보고받았다. 자료수집 이후 다차원척도법과 분류분석을 실시하였다. 다차원척도법 결과, 청각 및 시청각 ASMR 모두 핵심정서차원인 쾌불쾌 차원에서 잘 구분되었다. 분류분석 결과, 동일한 감각양상 및 서로 다른 감각양상의 ASMR에 대한 참가자 개인의 정서표상 구분과 참가자들간 정서표상 구분이 잘 이뤄졌다. 종합적으로 본 연구는 다른 정서유발자극들과 같이 ASMR 또한 핵심정서차원에 위치한다는 것을 시사한다는 점에서 기존의 Russell(1980)의 핵심정서차원 이론을 지지한다. 또한, 감각양상에 상관없이 ASMR에 대한 참가자 개인의 정서표상이 예측가능하며, 참가자들의 정서표상이 일관적이라는 점을 시사한다.

In this study, the reliability and validity of the retrospective pre-post test were analyzed in order to solve the problem of traditional pre-post test including response shift bias. Samples of the study were 162 elementary school students who are studying at the S university gifted education center in Seoul. Before completion of the field trip, we conducted pre test of science-related attitudes. After completion of the field trip, respondents were asked to compare their responses of pre and post science-related attitudes to quantitatively analyze the commonalities and differences of the two tests. To find out more characteristics, qualitative data such as daily records and interview were also gathered and analyzed. The major results of the study are as follows. First, for the paired t-test, there was no statistically significant difference between separate pre-test scores and retrospective pre-test. There was a very high correlation between the separate pre-test scores and the retrospective pre-test. Second, there were significant differences in all seven sub-factors of science-related attitudes between the retrospective pre-test and the post-test. Third, the separate pre-test scores showed a slightly higher tendency than the retrospective pre-test scores. This suggests that the response shift bias appears when it is performed the separate pre-test in affective domain. As a result of the interview, it was found that the evaluation standards of separate pre-test did not match with those of post-test. Forth, internal consistency reliability of the retrospective pre-test was higher than that of the separate pre-test. However, there were significant differences in six factors of science-related attitudes excluding the 'social implications of science' between the separate pre-test and the post-test. Based on these results, the retrospective pre-post test design provides simplicity and convenience to both respondents and investigators, as it is done with one test. The retrospective pre-post test design can be regarded as a valid design for the self-report measurement of affective domain on a single experimental group.

As the modern society is called the narcissistic society, the narcissism is widespread in the personality of individuals and the society at large. In consideration of this side, this study explored for several characteristics of the narcissistic personality and the job stress, and explored for the relationships between the two things theoretically. The narcissism is an attempt to repair self-esteem weakened by the splitting anxiety, the lack and the pathological fusion of self-structure. The job stress is a factor that a characteristic of the job influenced on the behavioral and affective response of the person on the job directly or indirectly. This study selected organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development as factors of the job stress. This study viewed that the stress is made from an interaction between environmental stimulus and personal particular reaction by defining the stress as an interaction model of stimulus-response and personal reaction is caused by psychological adjustment process, personal differences. On this occasion, this study discussed that the narcissistic personality is easy to get stress and weak in the job stress with regarding the personality as a mediation variation of psychological process. As a result, the narcissists estimated themselves positively and their self-esteem is high, but they excessively showed a self biased cognitive and affective response about the negative feedback to protect themselves. Moreover, this positive estimate on themselves and high self-esteem was vulnerable and weak in the self threat. In this view, the narcissistic personality is easy to get more job stress such as organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development.

Attentional processes facilitate cognitive and behavioral performance in several ways. Attention serves to reduce the amount of information to receive. Attention enables humans to direct themselves to appropriate aspects of external environmental events and internal operations. Attention facilitates the selection of salient information and the allocation of cognitive processing appropriate to that information. Attention is not a unitary process that can be localized to a single neuroanatomical region. Before the cortical registration of sensory information, activation of important subcortical structures occurs, which is called as an orienting response. Once sensory information reaches the sensory cortex, a large number of perceptual processes occur, which provide various levels of perceptual resolution of the critical features of the stimuli. After this preattentional processing, information is integrated within higher cortical(heteromodal) systems in inferior parietal and temporal lobes. At this stage, the processing characteristics can be modified, and the biases of the system have a direct impact on attentional selection. Information flow has been traced through sensory analysis to a processing stage that enables the new information to be focused and modified in relation to preexisting biases. The limbic and paralimbic system play significant roles in modulating attentional response. It is labeled with affective salience and is integrated according to ongoing pressures from the motivational drive system of the hypothalamus. The salience of information greatly influences the allocation of attention. The frontal lobe operate response selection system with a reciprocal interaction with both the attention system of the parietal lobe and the limbic system. In this attentional process, the search with the spatial field is organized and a sequence of attentional responses is generated. Affective, motivational and appectitive impulses from limbic system and hypothalamus trigger response intention, preparation, planning, initiation and control of frontal lobe on this process. The reticular system, which produces ascending activation, catalyzes the overall system and increases attentional capacity. Also additional energetic pressures are created by the hypothalamus. As psychophysiological measurement, skin conductance, pupil diameter, muscle tension, heart rate, alpha wave of EEG can be used. Event related potentials also provide physiological evidence of attention during information process. NI component appears to be an electrophysiological index of selective attention. P3 response is developed during the attention related to stimulus discrimination, evaluation and response.

Cardiac, respiratory, electrodermal and frontal (F3, F4) EEG responses were analyzed and compared during to slides of International Affective Picture System (IAPS) in the study on 42 students. Physiological responses during 20s of exposure to slides intended to elicit happiness (nurturant and erotic), sadness, disgust, surprise, fear or anger emotions were quite similar and were expressed in heart rate (HR) deceleration, decreased HR variability (HRV), specific SCR, increased non-specific SCR frequency (N-SCR), and EEG changes exhibited in theta increase, alpha-blocking and increased beta activity, and frontal asymmetry. However, some emotions demonstrated variations of the response magnitudes, enabling to differentiate some paris of emotions by several physiological parameters. The profiles showed higher magnitudes of HRV and EEG responses in exciting (i.e., erotic) and higher cardiac and respiratory responses in surprise. The most different pairs were exciting-surprise (by HR, HRV, theta, and alpha asymmetry), exciting-sadness (by theta, alpha, and alpha asymmetry), and exciting-fear (by HRV, theta, F3 alpha, and alpha asymmetry). Nurturant happiness yielded the least differentiation. Differences were found as well within negative emotions, e.g., anger-sadness were differentiated by HRV and theta asymmetry, while disgust-fear by N-SCR and beta asymmetry. Obtained results suggest that magnitudes of profiles of physiological variables differentiate emotions evoked by affective pictures, despite that the patterns of most responses were featured by qualitative similarity in given passive viewing context.
