The Internet is being utilized as a means of communication channel for science information. In this study, an experiment was conducted against college students, in which participants were assigned to one of the following four conditions: source status(professor, student) x social categorization(in-group, out-group). When the participants finished reading an online news article, perceived usefulness of and attitude toward the science technology were measured. The results show that the effect of source expertise on perceived usefulness was moderated by social categorization.

An experimental research investigated the components of lottery games affecting lottery-purchasing behaviors and the psychological consequences of the behaviors. In the experiment, participants were given a chance to purchase a lottery tickets during a series of computer games and their decision of purchasing the lottery ticket was measured. Also, the size and probability of the lottery games were manipulated and the perceived difficulty, satisfaction of the mid-outcome, and perceived probability of success in the computer game were measured in order to examine their impacts on participants' lottery-purchasing decisions. In addition, the behavioral tendency, satisfaction of the final outcome, and perceived self-capability in the computer game were measured at the end of the computer games in order to examine the effects of lottery-purchasing experiences on the variables. Participants who perceived the games as easier and estimated the probability of their success highly were more likely to buy the lottery tickets. However, the winning prize and odd of lottery tickets, perceived satisfaction of their own performance, and the performance itself did not influence the purchasing decisions. The common beliefs on the negative effects of lottery-purchasing experiences on human motivation and behaviors were not supported. The implications of the present research findings and limitations of the experimental research on lottery were discussed.

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.

The purpose of this paper is to evaluate the effects of perceived risk and brand attitude on licensing brands comparing with non-licensed brands(virtual brand). Data was collected through a self-administered questionnaire in quasi-experimental design setting. I designed the experimental setting that there were two virtual companies to sell the luxury bags(symbolic goods) or cruise tour(experiential goods) and to launch their goods with own brand or licensed brand. The experimental groups were composed of women consumers who were familiar with consuming experiential goods and symbolic goods. Results from the experiment suggest that consumer's perceived risk on brands gives a negative impact on brand attitude. And congruence in goods types and licensed brand values leads to difference in the level of perceived risk. In experiential goods, brand licensing from famous and experiential brands can reduce perceived risk. But in symbolic goods, brand licensing effect which reduces the perceived risk is less effective than in experiential goods. This findings suggest that brand licensing may lower the level of consumer's perceived risk, but incongruity in goods type and brand value may result in strategic failure.

The purpose of this study was to investigate the scope of color perception for Japan standard color. In addition to, we compared the difference in the color perception between the Korean and the Japanese undergraduates. 140 male and 119 female Japanese undergraduates were selected as the random sample. Color perception was made with the naked eyes. Minolta Chroma Metre CR 300 was used for physical measurement of the color. The results were as follows, 1) Japanese students' perceived color perception was classified into four large groups: simple group includes Red, Yellow, Blue, White, Gray and Black, X(-axis)group includes Green, Red Purple, Y(-axis)group includes Green, complex group includes Blue Green, Purple, Purple Blue, Red Purple. 2) There is difference between Korean color perception and Japanese; for Yellow Red, Blue, Blue Green, Red Purple. 3) There is little difference between the values of standard color and mean percept color for Yellow while big difference for Blue. And as for as country was concerned, Korean is more accurate than Japanese in color perception.

The current study examined the moderating effect of visual cues in eWOM on the relationship between perceived risk and purchase intention. Specifically, the study tested the different directions of the moderating effect in positive and negative eWOM. Two studies from a 2 (perceived risk: high vs. low) by 2 (visual cue: presence vs. absence) experimental design were used with online subjects. Findings from study 1 (n=123) supported that visual cues in positive eWOM help to reduce the negative effect of perceived risk on purchase intention. However, study 2 (n=122) showed that visual cues in negative eWOM intensify the negative effect of perceived risk on purchase intention. The findings demonstrated that visual cues in eWOM influence consumers' decision under high risk conditions. We discussed findings of this study how visual cues in positive and negative eWOM can be strategically managed for new online sellers.

Social exclusion, which does not fulfill the desire for respect as one of the most basic human desires, makes those who perceive themselves to be socially excluded seek physical warmth. However, very few studies have examined whether this phenomenon-wherein social exclusion develops a preference for warmth-can be generalized to the emotional or symbolic aspects, such as the color of lighting. This study aimed to verify the effects of perceived social exclusion on warm lighting preferences, and two experiments were performed for this purpose. In Experiment-1, participants who were respected by people the previous day were assigned to the group that did not perceive social exclusion (non-perceived social exclusion group), and those who were not respected were assigned to the group that perceived social exclusion (perceived social exclusion group). Following this, their preference for warm lighting (3000K), neutral lighting (4000K), and cold lighting (6000K) was measured. The results showed that the perceived social exclusion group had a stronger preference for warm lighting and a weaker preference for cold lighting than did their counterparts. Moreover, the perceived social exclusion group showed a strong preference for warm lighting over neutral lighting; they also showed a weak preference for cold lighting. In Experiment-2, after assigning the participants into groups as in Experiment-1, the participants' preference for a space with warm lighting, neutral lighting, and cold lighting was measured. The results showed that the perceived social exclusion group had a stronger preference for the space with warm lighting and a weaker preference for cold lighting than did their counterparts. Further, the perceived social exclusion group showed a strong preference for the space with warm lighting over the space with neutral lighting; they also showed a weak preference for the space with cold lighting. The findings of this study have implications that can be applied to designing living spaces for people who experience social exclusion, such as handicapped individuals, multicultural families, or immigrant workers, as well as developing artificial intelligence services and cyber-friend characters for this demographic.
