  • The gaze cueing effect appears as detecting a target rapidly and accurately when the direction of others' gaze corresponds with the location of the visual target. The gaze cue can be affected by the orientation of the face. The gaze cueing effect is strong when the face is presented upright, but the effect has only been observed in some studies when the face is presented inverted(e.g., Tipples, 2005). This study aimed to examine whether the gaze can operate as a cue to guide attention with upright faces, and to add variables that can affect the gaze cue, such as the orientation of the face, the orientation of the background, and a time interval between the gaze cue and the target(SOA). Furthermore, it systematically manipulated these variables to explore whether the gaze cueing effect can be observed under the various conditions. The results showed a significant gaze cueing effect even on the inverted face, contrasting with previous studies. These findings were consistently observed when the background stimulus was absent(Experiment 1) and present(Experiments 2 and 3). However, there was no significant interaction in the orientations between the face and the background. Moreover, in the short SOA(150 ms), we found a significant gaze cueing effect in conditions of every face and background orientation, whereas there was no significant gaze cueing effect in the long SOA(1000 ms). By presenting a consistent observation of the gaze cueing effect under the short SOA(150ms) even in the inverted faces, the results of this study pose questions about the reliability and repeatability of previous studies that did not report significant results of gaze cueing effects in that faces. Furthermore, our results are meaningful in providing additional evidence that attention can be guided toward the direction of the gaze even in various directions of the face and background.

  • This study investigated the difference of reference price, preference and quality perception of high functional underwear according to innovation cues. High functional underwear was selected as a research stimulus due to its technological innovative characteristics. A total of 93 male university students participated as subjects and data were collected by simple random experimental design operationalized with three types of innovation stimulus cues. Two types of internal reference price perception-expected price and fair price, preference, and 9 items of product quality perception-8 functional properties and overall quality of stimulus were measured with a questionnaire. The result supported the difference of reference price and quality perception by product innovation cue. The higher cue level group perceived two types of reference price and the overall quality higher than the lower cue level group. The difference of the expected price and fair price, the influence of functional properties on overall quality, and relations of the variables were discussed in depth.

  • Two experiments were performed to test whether the perception of subjective contours occurs not only through bottom-up processes but also throught top-down processes by manipilating such cognitive factors as superimposition cues and selective attention.In the first experiment,the phenomenon of neon color spreading effect was used to investigate the effect of superimpoed Kanizsa triangles.To identify the effect of superimposition, two different colors were used,one for each overlapped Kanizsa triangle,and the subjects were asked which neon-like color they saw for the overlapped portion.Result indicates that the only neon-like color of the superimposing triangle can be perceived,which implies that super impostition cues may act upon the formation process of subjective contour as a a sort of top-down information.In the second experiment,two partially ovwelapped Kanizsa squares of which direction of superimposition were ambiguous and thus reversable depending on the observer's mental set were used to inverstigate the effect of selective attention.Subjects were instructed to pay attention only to one of the squares and report the neon- like color of the overlapped portion of them.Result shows that the subjects perceive only the neon-like color of superimposing square,which implies that such cognitive factors as selective attention may strongly influence the formation of subjective contours. In conclusion,the results of this study show that the subective contour does not depend only on bottom-up processes but also on such cognitive factors as super-imposition cues and selective attention.

  • This study aims to understand what aspects among perceived environmental cues affect on satisfaction and behavior intention of visitors with the object of Gwangju Chungjang Festival 2008, which is a city festival. The survey was performed in the festival period, from October 7 through, 12 2008 with 300 visitors who finished the touring of the Festival. All the 300 questionnaires were returned, but only 270 out of 300 were used, except for the unfaithful responses, for the analysis. For statistical process of the collected data, frequency analysis, reliability analysis, factor analysis and multiple regression were performed by using SPSS 12.0 for Windows via the process of data coding. As the result, first, the factor, environmental cues of city festival were shown differently in three dimensions of satisfaction. In other words, 'food factor' is an important factor for festival satisfaction. Second, for re-visit intention, which is the consequence variable and behavior intention of satisfaction regarding the environmental cue factor, 'convenient facility factor' and 'accessibility and promotion factor' were significant and 'promotion and guidance factor' for the recommendation factor was significant. On the contrary, 'food factor' did not have significant impact. Third and finally, as the analysis result of impact of festival satisfaction on re-visit intention and recommendation intention, which are the behavior intentions, festival satisfaction was significant. This study aims suggestion of development strategies for Gwangju Chungjang Festival 2008. It is appropriate time for this study at the point of promoting city festivals. Also, suggestions in this study can help promotion of development direction.

  • 사람은 실내나 인공구조물을 가진 실외 환경에서 깊이를 지각하는데 소실점이라는 강력한 깊이 지각 단서를 활용한다. 소실점은 관찰자로부터 가장 먼 거리의 지점에 대응된다. 인간은 단안영상이 가지는 기하학적 성분을 이용해서 소실점을 추정하고, 소실점의 위치와 관찰자의 시점을 기준으로 상대적 깊이지각을 할 수 있다. 본 논문에서는 하나의 소실점을 가진 2차원 단안영상에서 유효한 소실점을 추정하고, 입력영상에 대한 소실점의 위치 관계를 이용한 상대적 깊이지도의 생성 방법을 제안한다.

  • 기억의 인출에 관여하는 전전두엽의 역할을 연구하기 위해 지각적 친숙성 정도가 다른 재인 조건을 비교하고, 이에 관여하는 뇌의 활성화 양상을 fMRI로 측정 분석하였다. 이를 위하여 동일조건; 그림으로 학습하고 동일한 내용의 다른 그림이 재인 단서로 주어지는 조건, 교차 조건; 단어로 학습하고 내용이 일치하는 그림이 재인 단서로 주어지는 조건이 비교되었다. 재인 수행(회상율, 정확도)은 동일 조건에서 가장 높앗으며 교차 조건에서 가장 저조하였다. 동일 조건 동안 양측 두정엽에서 가장 유의미한 활성화가 관찰되었으며, 상이 조건동안은 좌측 구조물들(Insular, 중 전전 두엽, hippocampal gyrus, 하두정엽 등)에서 활성화가 관찰되었다. 교차조건에서는 활성화가 좌우 시각 영역 및 두정엽의 연접부위 및 전두엽의 백질 부위(superior longitudinal fasciculus)에서 관찰되었다. 이는 그림의 인출과정에 우측 전두엽이 필수적인 것이 아니라, 인출에 수반되는 하위 정보처리 과정에 따라 다른 뇌 영역이 관여하고 있음을 시사한다. 예를 들어, 좌측 insular, 좌측 하 전전두엽에 의해 매개된 lexical processing이 상이한 그림의 재인과정에(상이조건), 시각피질과 좌측 전전두엽의 상호작용이 시각적으로 제시되었던 단어를 그림 단서로 인출하는 과정에(교차조건) 관여하고 있을 가능성을 시사하고 있다.

  • This study aims to characterize the effect of different combinations of chromatic-achromatic colors and area-ratio of stripe necktie, and gender on the image of male wearer. The experimental materials developed for this study are a set of stimuli and response scales. The stimuli consist of 84 color pictures manipulated with every combination of 12 different colors and 7 different area-ratio. The 7-point scale designed for visual evaluation of image formation included 26 bipolar adjectives. The subjects were 2016 undergraduate students in Gyeongnam, Seoul, Busan, and Daegu areas. The results of this study were as follows.; The analyses of images of male wearer in terms of combinations of chromatic-achromatic colors and area-ratio of oblique stripe necktie reveal that the concerned factors are of five characteristic dimensions of youth-activity, ability, attractiveness, appeal, and warmness. In addition, it has been found that individual images of male wearer are affected by observer's gender as well as combinations of chromatic-achromatic colors and area-ratio of stripe neckties and that those images vary with every combination of each factor. The study results are highly expected to be used as useful sources in developing necktie designs.

  • Size, velocity, and time equivalence are mechanisms that allow us to perceive objects in three-dimensional space consistently, despite errors on the two-dimensional retinal image. These mechanisms work on common cues, suggesting that the perception of motion distance, motion speed, and motion time may share common processing. This can lead to the hypothesis that, despite the spatial nature of visual stimuli distorting temporal perception, the perception of motion speed and the perception of motion duration will tend to oppose each other, as observed for objects moving in the environment. To test this hypothesis, the present study measured perceived speed using Müller-Lyer illusion stimulus to determine the relationship between the time-perception consequences of motion stimuli observed in previous studies and the speed perception measured in the present study. Experiment 1 manipulated the perceived motion trajectory while controlling for the retinal motion trajectory, and Experiment 2 manipulated the retinal motion trajectory while controlling for the perceived motion trajectory. The result is that the speed of the inward stimulus, which is perceived to be shorter, is estimated to be higher than that of the outward stimulus, which is perceived to be longer than the actual distance traveled. Taken together with previous time perception findings, namely that time perception is expanded for outward stimuli and contracted for inward stimuli, this suggests that when the perceived trajectory of a stimulus manipulated by the Müller-Lyer illusion is controlled for, perceived speed decreases with increasing duration and increases with decreasing duration when the perceived distance of the stimulus is constant. This relationship suggests that the relationship between time and speed perceived by spatial cues corresponds to the properties of objects moving in the environment, i.e, an increase in time decreases speed and a decrease in time increases speed when distance remains the same.
