This research investigated that participants' response time and recognition in the decision-making situation would vary according to either rational or emotional stimuli and analyzed how brain functions are related to each type of stimuli by means of fMRI. We tried to address the difference of cognitive processing between rational stimuli and emotional stimuli in the perspective of information processing theory. In order to achieve the research purpose above, we conducted two kinds of experiment studies. In study 1, subjects conducted decision-making task which selected which kind of information type the stimuli was after stimuli - rational stimuli or emotional stimuli - was randomly seen during experiment. During this experiment, we investigated the effect of each stimuli by measuring the duration from the onset time at which stimuli was shown to the response time at which subjects conducted decision-making. Furthermore, we compared the brain functions by finding out what kinds of brain areas were activated during the decision-making task. In study 2, subjects conducted recognition task at which subjects made a decision whether the stimuli was sees in the previous experiment or not. During the second experiment, we investigated the recognition effect by measuring the memory for each stimuli type. Moreover, we compared the cognitive processes during recognition by analyzing the differences of brain area functions. The results of two experiments above were as following. Firstly, regarding the response time as the effect of stimuli, we found that the effect of emotional stimuli was higher than that of rational stimuli. And regarding the recognition as the effect of stimuli, it was found that the effect of rational stimuli was higher than that of emotional stimuli. Secondly, the explanation about the characteristics of cognitive processes with the result of behavioral response by analyzing brain functions was as following. First of all, regarding the decision-making task which conducted for analyzing the effect of response time, the relatively high activated brain areas of rational stimuli were related with the functions of movement control or working memory, and the relatively high activated brain areas of emotional stimuli were connected with the functions of lingual processing.

The purpose of this study is to examine the effect of violin learning as to enhance the attention span and impulsiveness of children with Attention Deficit Hyperactivity Disorder(ADHD). Three children with ADHD, grade 2, 3, 4 were selected to participate in the research. A total of 15 session were given during 8 week time span, including a final performance session. For measurement, Korean-Child Behavior Checklist(K-CBCL), Home Situation Questionnaire-Revised (HSQ-R), Conners Teacher Rating Scale-Revised (CTRS-R) were administered before and after the implementation. Other behavioral checklist were used to record inappropriate or interruptive behaviors. The results showed that violin learning has increased attention span and reduced impulsive behaviors of all three children with ADHD. Along with these changes, the identified inappropriate behaviors reduced as sessions progressed. Also the changes observed within the music environment were generalized to non-music environment, such as family and school. These results also indicate that violin can be a therapeutic medium used in music therapy setting to bring positive changes for children with ADHD problems.

This study examines the relationship between customer experience, customer-influencer relationship quality, and customer behaviors. This study employed questionnaire survey and collected 413 data. The structural equation modeling (SEM) method is used to test the hypotheses of the study. As a result of the study, it was found that among customer experiences, emotional experience had a greater effect on hot IRQ than cold IRQ, and cognitive experience had a greater effect on cold IRQ than hot IRQ. And it was found that hot IRQ had a greater effect on relationship retention intention than recommendation intention, and cold IRQ had a greater effect on recommendation intention than relationship maintenance intention. This study provides various implications both theoretically and practically by examining the relationship quality between customers and influencers.

In this study, we conducted an empirical analysis to examine the effects of corporate cultural marketing activities on customer satisfaction and customer citizenship behavior through positive emotion variables. For this study, we conducted a survey on customers who have experienced cultural marketing activities of companies. The results are as follows. First, among the four factors of culture marketing activities, 'sponsorship','synthesis','style', and other factors excluding 'sales' factors influenced positive emotion. Second, positive emotion have a positive effect on customer satisfaction with products and services. Third, positive emotion affect voluntary customer citizenship behavior. As a result, it can be seen that the marketing activities of companies practicing cultural activities, differentiation of products and services based on culture, and formation of corporate culture emphasizing culture lead to positive emotion of customer. In addition, positive emotion are likely to lead to customer satisfaction with products and services, and furthermore, in order to create common value, it is sometimes possible to lead to customer citizenship behavior that voluntarily perform the same role as the company's spokesperson have. Based on the results of this study, it is necessary for domestic stakeholder to engage in innovative perspectives and ongoing activities based on the essential concepts of cultural marketing to secure customer and build competitive advantage.

Organic solvents are known toxic effects like vertigo, behavioral obstacle, distracting, and peripheral neuropathy in neuron areas. However, there have been few studies how neurotoxic solvents-exposed workers are affected by the cognitive load of preceding working memory tasks. Therefore, we used fMRI as to measure the neural correlates of working memory impairment in occupational workers who had from chronic exposure to organic solvent. Twenty-nine solvent-exposed workers were included in this study. Each participant concluded the verbal N-back tasks (1- and 2-back) during the fMRI acquisition. Within-group analyses showed fronto-parietal networks were active in each condition. Direct comparisons between 1- and 2-back showed higher activation during the 2-back than 1-back. We found that increased activation of these regions at lower task demand is associated with increased cost of implementing.

The present study compared computer users target-selection response patterns when the targets were varied in terms of their relative location and distance from the current position of the cursor. In Experiment 1, where the mouse was used as an input device, the effects of different directions and distances of simple target(small rectangle) on target-selection response were investigated. The results of Experiment 1 can be summarized as follows: (1) Overshooting was more frequent than either undershooting or correct movement and (2) this tendency was more prominent when the targets were presented in the oblique direction or in farther location from the current cursor position. (3) Although the overshooting and undershooting were more frequent in the oblique direction, the degree of deviation was larger in horizontal and vertical direction. (4) Time spent in moving the mouse rather than that spent in planning, calibrating or clicking was found to be the most critical factor in determining total response time. In Experiment 2, effects of the font size and line-height of the target on target-selection response were compared with regard to two types of input devices(keyboard vs. mouse). The results are as follows: (1) Mouse generally yielded shorter target-selection time than keyboard. but this tendency was reversed when the targets were presented in horizontal and vertical directions. (2) In general, target-selection time was the longest in the condition of font size of 10 and line-height of 100%, and the shortest in the condition of font size of 12 and line-height of 150%. (3) When keyboard was used as the input device, target-selection time was shortest in the 150% line-height condition, whereas in the mouse condition, target-selection time tended to be increased as the line-height increased. which resulted in the significant interaction effect between input device and line-height. Finally, several issues relating to human-computer interaction were discussed based on the results of the present study.

This study examines children's responses on Audie music activity based on Gordon's Music Learning Method. Subjects of study were 3 five year old children(2 boys, 1 girl) in kindergarten. Data collection drew from participatory observation, researcher journal, the classroom teacher interview. Where more specific data were necessary, video and digital camera recorded. The data were described, analyzed, and interpreted. The main findings in this study are as follows : The children who participated in Audie music activity showed desirable changes in many ways. Their music listening attitude was the one that changed most remarkably. At the beginning activity application, the children were not naturally and could not listen attentively while researcher was singing song without words. Gradually children could listen attentively to the researcher's singing without words. Through the Audie music activity, the children began to think carefully the tone and rhythm of music and to express themselves freely and creatively. At the beginning activity application, the children who showed negative responses and blocked up activity became gradually able to show positive aptitude and to amuse. Also the children who showed passive attitude and no responses became gradually able to react spontaneously.

Unilateral neglect is associated with stroke, a neurological disorder caused by cerebrovascular injury, and is a symptom of not recognizing or responding to the opposite stimulus of the cerebral hemisphere, mainly in the right cerebral hemisphere injury. In this paper, we implemented contents using Virtual Reality based on 10 items and contents of Korean Catherine Bergego Scale(K-CBS), which is used as a behavioral evaluation scale for unilateral neglect. Implemented contents can evaluate body disregard, motility disregard, visual and spatial disregard, auditory attention, etc., which are symptoms of unilateral neglected patients, and can confirmed progression of disease quantitatively by measuring time and rotation angle of head during visual recognition. This method is expected to be useful for rehabilitation training using convenient unilateral neglect diagnosis and its applied contents.

Three experiments compared two hypotheses on visual selection; perceptual load hypothesis and dilution hypothesis. The perceptual load hypothesis predicts that perceptual load of task-relevant processing determines the level of task-irrelevant processing whereas the dilution hypothesis predicts that competition for limited-capacity attentional resource, not perceptual load, determines the locus of selection. To compare the two hypotheses, we investigated the influence of perceptual load in visual search on response interference by a distractor. Experiment 1 and 2 manipulated perceptual load by the set size of a search array and the colors of a target and non-targets, respectively. As a result, distractor interference decreased with a set size regardless of perceptual load. In order to further test the set size effect, Experiment 3 manipulated the perceptual categories of non-targets and a distractor. The results showed that distractor interference decreased only when non-targets belonged to the same category as a distractor. Overall, the current findings support the dilution hypothesis, but not the perceptual load hypothesis, and provide the evidence that visual selection is constrained by capacity-limited, category-specific attentional resources.
