This paper aimed at analyzing the psychology of the people who tunes the car from the point of view of the theory of unconscious desire. The theory of unconscious desire to approach human psychology has two features. One point is that it can be applied only to human beings in the sense that animals does not have the unconscious. The other is that we can categorize some types of underlying unconscious desire instead of seeing human desire as the sundry desires according to the specific target. In this paper, we looked at the characteristics of each type of data obtained through interviews for people to tune the car from the point of view of the theory of unconscious desire.

Autonomic and EEG responses of 38 college students were studied during 60-sec long presentation of International Affective Picture System (IAPS )slides evoking, according to subjective reports, negative (disgust, sadness, surprise) and positive (happiness, exciting) emotional. states. Observed were significant heart rate (HR) deceleration, large skin conductance responses (SCR), moderate respiration frequency slowing, reduction of frontal (F 3, F 4 ) and occipital (O 1, O 2 ) fast alpha, and increases of theta, delta and beta relative spectral power values during the first 30 sec of exposure of IAPS pictures. Analysis carried out to differentiate emotion categories according to autonomic responses indicated that observed HR deceleration was larger in magnitude in surprise and sadness than in disgust, SCR amplitude higher in sadness than in disgust. EEC showed significant differences in theta (F 3, F 4 ) and delta (O 1) power increase in disgust vs. happiness, fast alpha (F 3, F 4 ) power was lower in surprise than in happiness, and slow beta power higher. in happiness than in disgust (0 1). Despite some differences. observed within discrete emotion conditions, overall responses pattern of monitored parameters exhibited similar profiles with few variations, most. obvious. in disgust state, which suggests that affective visual stimulation elicits stereotypical responses in a given passive viewing paradigm. However, the magnitude of physiological responses may vary to certain extent across discrete emotional states making it possible to differentiate among particular experimentally-induced emotional states, e.g., disgust vs. sadness by ANS responses or disgust vs. happiness by EEG measures.

본 연구는 개인이 가지고 있는 정서지능 수준의 차이와 타인이 표현하는 정서가 가지는 목표관련성의 차이에 따라서 권력이 타인정서 인식능력에 미치는 영향력이 달라지는가를 알아보고자 하였다. 첫 번째 실험에서는 참가자들의 정서지능을 측정한 후, 권력을 조작하여 사진 속 주인공의 정서를 판단하도록 하였다. 두 번째 실험에서는 사진 속 주인공의 정서가 가지고 있는 목표관련성을 조작 한 후, 실험 1과 동일하게 권력을 조작하고 정서판단과제를 실시하였다. 실험 결과, 권력을 가진 집단은 기존의 연구 결과와 마찬가지로 권력을 갖지 못한 집단보다 타인의 정서에 대한 민감도가 떨어지는 것으로 나타났다. 한편 개인의 정서지능이 높은 경우에는 권력이 타인정서 인식능력에 미치는 영향력이 작았으나 중간 정도의 정서지능을 가진 참가자들은 권력의 영향을 많이 받았다. 또한, 사진 속 정서의 목표관련성이 높은 집단에서는 권력을 가졌음에도 불구하고 비교적 높은 수준의 정서판단의 정확도를 보였다. 또한, 능력으로써 정서지능의 역할을 확인하였고 권력을 가졌다 할지라도 타인의 정보에 대한 동기수준을 유연하게 조절할 수 있다는 점을 밝혔다는 점에서 이론적 공헌이 있다.

Intensity of background noise is a factor significantly affecting both subjective evaluation of experienced stress level and associated electroencephalographic (EEG) responses during mental load in noisy environments. In the study on 27 subjects we analyzed the influence of the background white noise (WN) intensity on psychophysiological responses during a word recognition test. Electrocortical activity were recorded during baseline resting state and 40 s long performance on 3 similar Korean word recognition tests with different intensities of background WN (55, 70 and 85 dB).. An important finding in terms of physiological reactivity was similarity of all physiological response profiles between 55 and 70dB WN, i.e., none of physiological variables differentiated the two conditions, while 85dB WN resulted in a significantly different profile of reactions (higher fast beta power in EEG spectra). This condition was characterized by highest subjective rating of experienced stress, had more fast beta activity and had tendency of right hemisphere dominance, emphasizing the role of brain lateralization in negative affect control.

The paper is addressed to the topic of physiological response-specificity in disgust induced by visual stimulation. The purpose of this study was to evaluate reproducibility of physiological reactivity pattern during disgust elicited by the International Affective Pictures System (IAPS) in 2 experiments. Twenty-nine subjects participated in the first experiment with 3 visual stimulation sessions with disgust-eliciting slides (3 slides in each 1 min long session). In the second experiment disgust-eliciting slides from the IAPS were presented to 42 subjects in 2 sessions (one slide for 1 min). Spectral power of frontal EEG, skin conductance (SCL, SCR and NS.SCR), heart rate(HR), heart period variability(HPV) and respiration rate were recorded. Visual stimulation evoked 1:.n deceleration, higher power of high frequency component of HPV, increased SCL and NS.SCR frequency, frontal slow alpha blocking and moderate increase in fast beta power in most of the sessions in both experiments. However in the second experiment the EEG pattern associated with disgust showed inconsistent shifts in fast alpha and slow beta bands, but was marked by higher power of theta activity. Our data in both experiments emphasizes presence of disgust-specific profiles of autonomic and at the less extent EEG responses in visual stimulation context. Discussed are potential behavioral mechanisms leading to observed physiological manifestations in disgust elicited by visual stimulation. The results support the consideration that disgust is an withdrawal type negative valence emotion associated with relatively low autonomic arousal (low HR, low amplitude SCRs with relatively high NS.SCR frequency) and moderate EEG activation signs. Obtained data showed more consistent reproducibility of disgust-specific autonomic rather than EEG response patterns during visual stimulation design.

The purpose of the current study was comparative analysis of autonomic and electrocortical responses to passive and active touch of the tektites with different subjective emotional preference. Perspective goal of the project is development of a template for classification of tactile stimuli according to subjective comfort and associated physiological manifestations. The study was carried out on 36 female college students. Physiological signals were acquired by Grass and B10PAC 100 systems with AcqKnowledge III software. Frontal, parietal and occipital EEG (relative power spectrum /percents/ of EEG bands - delta, theta, slow and fast alpha, low and fast beta), and autonomic variables, namely heart rate (HR), respiratory sinus arrhythmia (RSA), pulse transit time (PTT), respiration rate (RSP) and skin conductance parameters (SCL, amplitude, rise time and number of SCRs) were analyzed for rest baseline and stimulation conditions. Analysis of the overall pattern of reaction indicated that autonomic response to tactile stimulation was manifested in a form of moderate HR acceleration, RSP increase, RSA decrease (lowered vagal tone), decreased n and increased electrodermal activity (increased SCL, several SCRs) that reflects general sympathetic activation. Parietal EEG effects (on contra-lateral side to stimulated hand) were featured by short-term alpha-blocking, slightly reduced theta and significantly increased delta and enhanced fast beta activity with few variations across stimuli. The main finding of the study was that most and least preferred textures exhibited significant differences in autonomic (HR, RSP, PTT, SCR, and at less extent in RSA and SCL) and electrocortical responses (delta, slow and fast alpha, fast beta relative power). These differences were recorded both in passive and active stimulation modes, thus demonstrating reproducibility of distinction between most and least emotionally preferred tactile stimuli, suggesting influence of psychological factors, such as emotional property of stimulus, on physiological outcome. Nevertheless, development of sufficiently sensitive .and reliable template for classification of emotional responses to tactile stimulation based on physiological response pattern may require more extensive empirical database.

P300 숨긴정보검사에서는 조사대상자가 거짓을 말하고 있는지 판단하기 위하여 관련자극의 P300 진폭이 무관련자극의 P300 진폭보다 통계적으로 유의하게 더 큰지를 평가한다. 구체적인 통계적 방법으로 독립표본 t 검증 또는 부트스트랩 방법을 사용할 수 있다. Rosenfeld와 Soskins, Bosh, Ryan(2004)은 "개인 내에서 관련자극과 무관련자극의 P300 평균을 비교하는데 사용하기에는 t 검증이 너무 둔감하다."면서 부트스트랩 방법을 사용하였다. 본 연구의 목적은 P300 숨긴정보검사에서 t 검증의 검증력이 부트스트랩 방법보다 더 낮은지 평가하는 것이다. 이를 위하여 39명의 실험참가자로부터 측정한 뇌파자료를 이용하여 Monte Carlo 연구를 수행하였다. 연구결과, t 검증과 백분위를 이용한 부트스트랩 방법의 1 종 오류율은 서로 비슷하였으며, 백분위를 이용한 부트스트랩 방법의 검증력이 t 검증의 검증력보다 약간 더 높았다. 두 검증 방법의 1 종 오류율은 모두 유의수준보다 낮은 값을 보였으며, 검증력은 이론적인 t 검증의 검증력보다 약간 낮은 값을 보였다. 반면에 표준오차를 이용한 부트스트랩 방법의 1 종 오류율과 검증력은 이론적인 t 검증의 1 종 오류율 및 검증력과 비슷한 값을 보였으며, t 검증의 검증력보다 실험조건에 따라 .012 ~ .081 더 높았다.
