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.

To investigate how the valence of unattended background picture modulates perceptual processing of a target letter, participants were required to detect a target letter among six letters superimposed on an IAPS picture. Perceptual load was manipulated by varying the difficulty of letter detection, and behavioral results showed more accurate and faster detection responses at the low-load condition than at the high-load condition. The analysis of ERP data of control condition at which six letters were presented without an IAPS picture showed perceptual load effects on mean amplitude of N1 and P1 ERP components. At experimental condition including an IAPS picture, interaction between valence and perceptual load was observed on mean amplitude of N1 at posterior visual processing area, and the amplitude difference between low-load condition and high-load condition was larger on a negative background picture than on a neutral background picture. The results suggest that more attentional capacity might be consumed by a negative picture than by a neutral picture, and suggest that unattended affective picture is processed automatically and influence the early perceptual processing of target stimulus.

The mental health of dementia family has been an important topic of research. This study aims to examine the effect of caregiving burden on depression of dementia family caregivers and to verify the moderating effect of the public support that the caregivers perceived. The sample was collected using a quota sampling method and purposive sampling method by selecting 10 institutions from 3 stratified districts in Korea. Since the purpose of the research was to examine ongoing family caregiver burden, 208 responses that matched the purpose of the research were selected. Results showed that the depression of dementia family caregivers was associated with the caregiver burden. The moderating effect of the perceived public support on depression was verified. Based on the results, intervention strategies Results suggest that by increasing perceived public support, depression due to caregiver burden may be reduced or prevented.

As quickly becoming an ageing society in Korea, this study aims to investigate how family caregivers' burden with demented patients and social supports are related to their health and quality of life, and the interaction of caregiving burden and social supports on caregivers' health and quality of life. The participants were 207 family caregivers (106 females) of demented patients lived in Seoul, Kyunggi, and Chungcheong areas, whose average of age were 51.62 ( SD=9.25). The psychological tests used in this research included the following: Multidimensional Caregiver Burden Inventory, Chon's Physical Symptom Questionnaire, Hahn & Jang's Perceived Health Inventory, Negative Affect Self-Statement Questionnaire, and the Korean Version of Cambell's Subjective Well-being Scale, Social Support Survey in Medical Outcomes Study, and Kwon's Questionnaire for Maladjusted Problems of Demented. Results indicated that caregivers' burden with demented patient related to physical symptoms and depression positively, and perceived health and subjective well-being negatively. Social supports showed moderate effects on influences of caregiving burden in perceived health, depression, and subjective well-being of family caregivers with demented patients. It was identified the possibility of their buffering effect on negative results of caregiving burden with demented patients. Since caregiving burden accounted for the 34% of the variances for family caregivers' physical symptoms and depression, researchers discussed the promotion and intervention of their health and quality of life. Beside of different effects of social supports with level of caregiving burden, with previous studies it was discussed some saliant findings such as family caregivers with patients who showed severe dementia symptoms were perceiving even less supports from others.

The purpose of this study was to analyze the perceptions of local residents towards the impact of Geumsan ginseng festival. This study was trying to examine the perception differences between groups of resident by tourism relatedness. Self-administered questionnaire survey was administered for the Geumsan residents. Frequency analysis, factor analysis, regression analysis, and t-test was administered for the perception differences. Using social exchange theory, it was revealed that tourism relatedness was relatively useful to test the perceptions differences of residents towards festival impacts. Tourism related residents perceived positive impacts more strongly and negative impacts Jess strongly compare to non related residents. The result suggested that residents' perception of festival impacts was dependent on the level of tourism relatedness and implications are drawn for community tourism policy and management.

Learning the principles of perception belongs to both the psychology and art field. However, people define that an art education is an activity of expression, so an activity of an art appreciation is either downsized or hardly proceeded in an art class. Therefore, the art appreciation educational program that gives a motivation to appreciate the work of art and to minimize a burden towards the activity of an art appreciation is needed. This paper proposes an educational program that includes activities to appreciate the work of art using the principles of perception and to create personal portfolios. Also, we analyze the eye movement of the paintings according to the principles of perception. Finally, proposes the art appreciation education program based on Feldman's critique method. In addition, we illustrate the example of the proposed art appreciation educational program with the analyzed paintings from section III.

This study is to identify perceptions and response degrees of anxiety for each factor, targeting patients for CT test and analyze the relations between factors. It is to provide scientific fundamental data to reduce anxiety by improving awareness of patients about CT test by analyzing relations between variables. The subjects of this study were surveyed in self-writing type, targeting 263 patients for CT test in the department of radiology at three University hospitals from July to September, 2010. This survey was executed once by a structured self-administered survey type. The targeting patients for CT test of anxiety will investigate for affect. Anxiety by each CT test variables depending on CT test-related features showed independent variable is Expense Responsibility, Economic burden, Sufficient explain, Explain agent, Endoscope, Biopsy, Pre treatment, Previous experience, CT side effect experience, Side effect of contrast medium and dependent variable is physical, Hospital staff, Hospital environment, Socioeconomic These used statistics program SPSS (ver. 13.0). Summarizing the above results of this study, awareness of anxiety and response to it in each variable under CT test appeared significant differences in economic burdens, state anxiety, pre-treatment anxiety, exposure anxiety to radiation, and anxiety of side effect. Therefore, pre-treatment before test and pre-training programs on chemical poison of contrast medium and side effect seem to be able to release patients' anxiety level for CT test. Ways to meditate these anxiety variables and reduce degree of anxiety are needed to be researched more and updated. In addition, impact of patients' economic burdens on CT test anxiety is required to be recognized and solved in society level.

This study was conducted to identify the social perception of schizophrenic patients through films expressed in schizophrenic patients. We analyzed 48 films and scenarios that have been screened for the last 40 years by content analysis method to perceive interpersonal and emotional perception, perception of families and treatment measures. Patients were violent, dangerous, and burdensome to the family. However, specific experience or internal description has increased, and attitude of family or patients related to treatment has been more actively described since 1996. In conclusion, the perception of patients seen negative, want to avoid, giving burdens and pain to others. Therefore, to improve the social perception of mental disorders, it is necessary to make active use of films that have a high impact on public perception, and try to study the influence of visual media on perception change.
