This study examined the mediating effects of irrational beliefs on the relationships of middle school students' autonomy of psychological growth environment and behavioral anger responses(impulsive reaction, verbal aggression, physical confrontation and indirect expression). A sample of 346 first and second year students of middle school participated in the autonomy of psychological growth environment scale, the irrational beliefs scale and behavioral anger responses scale. Pearson's correlation analysis and regression analysis were performed. The results showed that: ⑴ The relations among autonomy of psychological growth environment, irrational beliefs and behavioral anger responses were significant. The autonomy of psychological growth environment had negative correlations with irrational beliefs and behavioral anger responses. Irrational beliefs produced positive correlations with behavioral anger responses. There were positive correlations among the subtypes of behavioral anger responses. ⑵ There were mediating effects of irrational beliefs between autonomy of psychological growth environment and behavioral anger responses. The effects of autonomy of psychological growth environment on impulsive reaction, physical confrontation and indirect expression were fully mediated by irrational beliefs. However, the effect of autonomy of psychological growth environment on verbal aggression was partially mediated by irrational beliefs. This study demonstrated that irrational beliefs mediate the relationship between autonomy of psychological growth environment and behavioral anger responses.

Objective: This entire study has two parts. Study I aimed to develop a psychological assessment scale and the study II aimed to investigate the effects of LFN (low frequency noise) on the psychological responses in humans, using the scale developed in the study I. Background: LFN is known to have a negative impact on the functioning of humans. The negative impact of LFN can be categorized into two major areas of functioning of humans, physiological and psychological areas of functioning. The physiological impact can cause abnormalities in threshold, balancing and/or vestibular system, cardiovascular system and, hormone changes. Psychological functioning includes cognition, communication, mental health, and annoyance. Method: 182 college students participated in the study I in development of a psychological assessment scale and 42 paid volunteers participated in the study II to measure psychological responses. The LFN stimuli consisted of 12 different pure tones and 12 different 1 octave-band white noises and each stimulus had 4 different frequencies and 3 different sounds pressure levels. Results: We developed the psychological assessment scale consisting of 17 items with 3 dimensions of psychological responses (i.e., perceived physical, perceived physiological, and emotional responses). The main findings of LFN on the responses were as follows: 1. Perceived psychological responses showed a linear relation with SPL (sound pressure level), that is the higher the SPL is, the higher the negative psychological responses were. 2. Psychological responses showed quadric relations with SPL in general. 3. More negative responses at 31.5Hz LFN than those of 63 and 125Hz were reported, which is deemed to be caused by perceived vibration by 31.5Hz. 'Perceived vibration' at 31.5Hz than those of other frequencies of LFN is deemed to have amplified the negative psychological response. Consequently there found different effects of low frequency noise with different frequencies and intensity (SPL) on multiple psychological responses. Conclusion: Three dimensions of psychological responses drawn in regard to this study differed from others in the frequencies and SLP of LFN. Negative psychological responses are deemed to be differently affected by the frequency, SPL of the LFN and 'feel vibration' induced by the LFN. Application: The psychological scale from our study can be applied in quantitative psychological measurement of LFN at home or industrial environment. In addition, it can also help design systems to block LFN to provide optimal conditions if used the study outcome, .i.e., the relations between physical and psychological responses of LFN.

This study investigated the psychological and physiological responses to the sound of car horns produced by different. manufacturers. Ten female college students listened to the sound of the horns while their EEG responses on 6 sites were being measured, and rated each hem on psychological scales. Their EEG and psychological responses were investigated as to whether the responses were related to the loudness, sharpness, tonality, and roughness of the horns. The results indicated that the subjects felt more 'dominated' as the loudness and sharpness increased, that the subjects felt more 'pleasant' as the sharpness increased, that the subjects felt more 'dominant' as the tonality increased, and that the subjects felt more 'aroused' as the roughness increased. The physiological results showed that the fast alpha wave in the occipital lobe decreased in the relative power as the loudness, sharpness, and tonality increased, and that the delta wave in the occipital lobe increased and the slow alpha wave in the frontal lobe decreased in the relative power as the roughness increased.

This study examined difference in the responses of children and therapists depending on children's problem type(internalization or externalization) and the therapists' levels of psychological burnout. Play therapy' cases (March 2010 ~ September 2011) were successfully concluded in more than 36 sessions, which targeting 14 children aged 4~9 who had emotional and behavioral problems and two therapists who consulted with the children. To examine the change in the play therapy stepwise process in this case, the responses in the children and the therapists were examined by dividing the stages of therapy into the early stage, the middle stage, and the late stage. The Results showed that (1) the children's response during the play therapy process were not significant different for both types of children's problems. Moreover, there were no differences with different levels psychological burnout by the therapist. (2) A change in the children's response during the play therapy process was noted in both children who had internalization problem and in those who had externalization problems. Moreover, according to the therapist's levels of psychological burnout, a change in the children's responses was indicated in the play therapy process. (3) The therapist's responses in the play therapy process did not show significant difference according to children's problem type or therapists' levels of psychological burnout. (4) A significant difference was noted in the responses between the therapists experiencing psychological burnout depending on their level.

This research examines how various dimensions of physical environments influence patrons' psychological responses(especially emotional responses) in the restaurant service setting, and how these emotional responses, in turn, influence patrons' attitude formation. The result of empirical research indicates that restaurant physical environments have a significant effect patrons' emotional responses, and that these psychological experiences serve as critical mediators in the restaurant physical environments-store attitudes relationship. However, the effects of restaurant physical environments on patrons' psychological responses varied with the dimensions of physical environments. First, the effect of cleanliness on emotional responses was most significant, especially on negative emotion, out of 4 dimension of restaurant physical environment. Second, ambient conditions are the most important predictor on customers' positive emotion, and in turn, positive emotion has the most significant effects on customers' attitude formation of restaurant. Therefore, the result suggests that restaurants should manage(or, improve) their ambient conditions(e.g. background music, scents, ventilation, noise etc.) for efficiently maximizing customers' positive attitude. The implications of this study are discussed, and ideas for future work suggested.

This study intended to explore fundamental causes affecting consumers' response actions from psychological factors in the situation of sellout occurring during shopping in online fashion stores. In addition, this study devised a virtual online shop in order to measure consumers' cognitive and emotional psychological responses they experienced when goods were sold out. The subjects involved women in 20s~30s, major customers of online shopping, and the subjects were randomly allocated to one of eight questionnaire forms (2(stockout size: high vs low)${\times}2$(product assortment similarity: similar vs. dissimilar)${\times}2$(restocking cue: included vs excluded)). The number of final data used for the analysis was 336 and through SPSS 21.0 program, two-way ANOVA and bootstrap were utilized. The analysis result was that consumers' psychological responses (emotions, psychological reactance) of online shops differed by means of varying stockout situations. The stockout size had positive effect on psychological reactance and negative emotions. On the other hand, there was no difference in positive emotions (arousal) according to stockout size. In stockout situation of online fashion store, the moderating effect of product assortment similarity and restocking cues were verified. According to the analysis result, interaction effects between stockout size and restocking cues, product stockout size and product assortment for psychological reactance were significant. Lastly, the mediation effect of psychological reactance and emotion between stockout size and behavioral response was tested. As a result, the moderated mediation effects of psychological reactance for substitute were significant when product assortment was dissimilar and restocking cue was exclude.

It is important to understand psychological and physiological responses of occupants who seated in a chair in order to shape a comfortable indoor official environment. So it is needed to find out optimal seated conditions. The purpose of this study was to explore optimal condition of seat air conditioning control based on psychological or subjective responses (perceived temperature and comfort sensation) and physiological responses (heartrate variability; HRV). To do this, experimental conditions were designed by the difference of indoor temperature and seat air conditioning temperature. In the experiment 1, seven experimental conditions were designed with one control condition which was not used seat air conditioning system, and six experimental conditions which the difference of indoor temperature and seat air conditioning temperature ($-1^{\circ}C{\sim}-6^{\circ}C$). In the experiment 2, four experimental conditions were designed with one control condition and three experimental conditions ($-3^{\circ}C{\sim}-5^{\circ}C$). In addition, participants' psychological or subjective response was measured by CSV (comfort sensation vote) and PTS (perceived temperature sensitivity) as a psychological or subjective response, and heartrate variability was measured as a physiological response. As a result, in the experiment 1, it was reported that the optimal conditions of seat air conditioning control based on participants' psychological or subjective comfort were from $-3^{\circ}C$ to $-5^{\circ}C$ experimental conditions. In addition, in the experiment 2, it was reported that the optimal condition of seat air conditioning control based on participants' physiological comfort was $-4^{\circ}C$ experimental condition. These results suggested that seat air conditioning could affected to comfort sensation of occupants in an appropriate range, rather than unconditionally.

Objectives: This study aims to examined whether physical activity prevent the negative effect of psychological stress on cardiovascular reactivity by reducing stress induced sympathetic output and preventing norepinephrine depletion negative psych-affective responses. It is assumed that physical activity reduces the magnitude of cardiovascular responses and psychological responses to stress which threaten individuals' physical and mental health. The result of investigating the effect of physical activity on reducing negative physiological and psychological responses would suggest useful information health for practitioners who want to prevent stress-induced diseases, especially coronary heart disease. Methods: participants of this study were 30 students (10 males & 20 females), whose mean age was 21.30 (SD=2.29). Fifteen students (5 males & 10 females) were assigned for in each group, treatment and control groups. They were interviewed and given a survey that included a consent form, demographics sheet and psychological tests, such as State-Trait Anger Expression Inventory and State-Trait Anxiety Inventory. Before the application of psychological stress, participants in treatment group were going through with a course of physical exercise, running on treadmill 15minutes, while participants in control group were not physically active. After exercise, there was 15 minutes resting period before applying cognitive stress. During the experiment, all participants performed challenging cognitive tasks for 20minutes in situations that were designed to experience learned helplessness and measured their cardiovascular reactivity including blood pressure and heart rate every 5 minutes, until 10 minutes after finishing the application of psychological stress(recovering state). In the end of experiment, they were given some psychological test again. Results: Heart rates of exercise group were significantly higher than non-exercise group, especially, five minute after applying cognitive stress and at the end of recovery, in other word 10 minutes after stressful event. Systolic blood pressures of exercise group were lower than those of non-exercise group during the stressful event, but this differences in borderline level of significance. state anger level of exercise group decreased even experiencing stress, while those of non-exercise group increase. And state anxiety level of exercise group decreased in borderline level of significance. Conclusion: This study reiterate health benefits of physical activity and suggest that regular moderate exercise may regulate cardiovascular reactivity and psycho-affective responses from stress by reducing stress induced sympathetic output.

This research examines how various dimensions of physical environments influence employees' emotional responses in restaurants, and how these emotional responses, in turn, influence employees' group cohesiveness. The result of empirical research indicates that restaurant physical environments have a significant effect on employees' emotional responses, and that these psychological experiences serve as critical mediators in the physical environment-group cohesiveness relationship in restaurants. However, the effects of physical environ-ments of restaurants on employees' psychological responses varied with the dimensions of physical environ-ments. First, the effect of spatial layout and functionality on pleasure and dominance was significant, not on arousal. Second, ambient factors influence on all dimensions of emotional responses, including the arousal level. In turn, all dimensions of emotional responses have significant effects on employees' group cohesive-ness. Therefore, the result suggests that restaurants should manage(or, improve) their physical environment conditions for inducing employees' positive emotional responses.

The objectives of this study were to investigate physiological and psychological responses to the rustling sound of Korean traditional silk fabrics and to figure out objective measurements such as sound parameters and mechanical properties determining the human responses. Five different traditional silk fabrics were selected by cluster analysis and their sound characteristics were observed in terms of FFT spectra and some calculated sound parameters including level pressure of total sound (LPT), Zwicker's psychoacoustic parameters - loudness(Z), sharpness(Z), roughness(Z), and fluctuation strength(Z), and sound color factors such as ${\Delta}L\;and\;{\Delta}f$. As physiological signals, the ratio of low frequency to high frequency (LF/HF) from the power spectrum of heart rate variability, pulse volume (PV), heart rate (HR), and skin conductance level (SCL) evoked by the fabric sounds were measured from thirty participants. Also, seven aspects of psychological state including softness, loudness, sharpness, roughness, clearness, highness, and pleasantness were evaluated when each sound was presented. The traditional silk fabric sounds were likely to be felt as soft and pleasant rather than clear and high, which seemed to evoke less change of both LF/HF and SCL indicating a negative sensation than other fabrics previously reported. As fluctuation strength(Z) were higher and bending rigidity (B) values lower, the fabrics tended to be perceived as sounding softer, which resulted in increase of PV changes. The higher LPT was concerned with higher rating for subjective loudness so that HR was more increased. Also, compression linearity (LC) affected subjective pleasantness positively, which caused less changes of HR. Therefore, we concluded that such objective measurements as LPT, fluctuation strength(Z), bending rigidity (B), and compression linearity (LC) were significant factors affecting physiological and psychological responses to the sounds of Korean traditional silk fabrics.
