The aim of this study was to investigate how the psychological factors of human interrelation or human socialization are associated with the visual design based on sociological and psychological theories. To accomplish this goal, human socialization was examined on the basis of physiology, philosophy, and psychology. Then a case study was employed to assess how they function in the area of visual design. In literature, the sources of psychological factors of human socialization were categorized into 11 items including the sexual hedonic pursuit. These items were used for the evaluation of 40 printed media advertisements, all of which were the winners of the Korea Advertising Awards from 1994 to 2003. As a result, it was revealed that most advertisements responded to the items of adaptive value and cultural imprinting as biological bases. Also, it was discovered that the existential foundation of advertising has been based on mutual distrust and the payoff matrix as a mind of social unrest. In conclusions, it was illustrated that future advertising will remain based on adaptive value, cultural imprinting, social learning, and imitation learning, as long as advertising continue to hold its reason for existence.

Many objects are always present in a visual scene. Since the visual system has limited capacity to process multiple stimuli at a time, how to cope with this informational overload is one of the important problems to solve in visual perception. This study investigated the suppressive interactions among multiple stimuli when attention was directed to either one of the stimuli or all of them. The results indicate that suppressive interactions among multiple circles were reduced in V4 when subjects paid attention to one of the four locations, as compared to the unattended condition. However, suppressive interactions were not reduced when they paid attention to all four items as a set, in order to compute their mean size. These results suggest that whereas focused attention serves to later out irrelevant information, distributed attention provides an average representation of multiple stimuli.

The purpose of this article is to investigate the effect of visual working memory, the types and contents of graphic annotations on English learning. The participants of the experiments were 5th and 6th graders. The result showed that animation was effective only in the word test for children with large visual working memory, whereas text-only-annotation yielded better performance in the comprehension test in Experiment 1. The effect of relevance of animations was tested in Experiment 2. Context-relevant-animations yielded better comprehension than the animations denoting the typical meaning, whereas the opposite pattern was reported in the word test. The result of the two experiments was interpreted in terms of cognitive load theory and the generative theory of multimedia learning.

A recent study of visual working memory(VWM) under a change detection paradigm proposed an idea that the comparison process of VWM representations against incoming perceptual inputs can be performed more rapidly than the process of forming durable memory representations into VWM. To test this hypothesis, we compared the size of interference effect caused by pattern-backward masks following after either the sample(sample-mask condition) or test items (test-mask condition). In Experiment 1, subjects performed a color change detection task for four colored-boxes, and pattern masks with mask-onset asynchronies(MSOA) of either 64ms or 150ms followed each item location either after the sample or after the test items. The change detection accuracy was both comparable in the sample-mask condition regardless of the MSOAs, whereas the accuracy in the trials with a MSOA of 150ms was substantially higher than the MSOA of 65ms in the test-masking condition. In Experiment 2, we manipulated setsizes to 1, 2, 3, 4 items and also MSOAs to 117ms, 234ms, 350ms, 484ms and compared the pattern of interference across a variety of setsize and MSOA conditions. The sample-mask condition yielded a pattern of masking interference which became more evident as the setsize increases and as the MSOA was shorter. However, this pattern of interference was less apparent in the test-mask condition. These results indicate that the comparison process between remembered items in VWM and perceptual inputs is less vulnerable to interference from pattern-backward masking than VWM consolidation is, and thus support for the recent idea that the comparison process in VWM can be performed very fast and accurately.

In the early 1900, photography, magic lantern and cinema were simultaneously introduced and experienced until the mid-1910s as mysterious and magical symbol of modern science and technology. The technology of vision, cinema in particular demonstrated its commercially expandable potentials through serial films in the mid-1910s, silent cinema in the 1920s and talkies in 1930s. I argue that a metaphor 'like a movie' which was would be spoken out by peoples as a cliche ever since the late 1910s whenever they encountered something uncanny, mysterious, and looking wholly new phenomena informs how cinematic technology worked in colonial society at the turning point to the early 20th century. Mass in colonial society accepted cinema and other visual technologies not only as an advanced science of the times but as texts of modernity that is the reason why cinema had so quickly taken cultural hegemony over the colony. Until the mid-1920s, discourse on cinema focused not on cinema itself, rather more on the theatre matters such as hygiene, facilities for public use, disturbance, quarrels and fights, theft, and etc. Since the mid-1920s and especially in wartime 1930s, discourses about negative influences and effects of cinema on behavior, mind and spirit of masses, bodily health, morality and crime were articulated and delivered by Japanese authorities and agencies like as police, newspapers and magazines, and collaborate Korean intellectuals. Theories and research reports stemming from disciplines of psychology, sociology, and mass-psychology that emphasized vulnerability and susceptibility of the crowd and mass consumers who would be exposed to visual images, spectacles and strong toxic stimulus in everyday lives. Those negative discourse on influences and effects of cinema was intimately associated with fear of the crowd and mass as well as new technology which does not allow clear understanding about how it works in future. The fact that cinema as a technology of vision could be used as an apparatus of ideology and propaganda stirred up doubts and pessimistic perspectives on cinema influence. Discourse on visual technology cinema constructed under colonial governance is doomed to be technology of mass control for empire's own sake.

This study assumed two key parameters that describe smoothness. Previously, the number of studies that defined smoothness with the concept of curvature has been limited. The parameters were the two physical characteristics of curvature: the number of waves and the amplitude of them. The purpose of the study was to observe which of the two parameters influences the perception of smoothness and to examine the relationship between the sense of aesthetic beauty and smoothness. The visual stimuli used in the study were transformed three-dimensional spheres, based on the combination of the three levels of the two parameters of nine distinct conditions. We analyzed the three responses that measured the preference of each visual stimuli, the familiarity score, and the smoothness evaluation score, each with the linear mixed model whose fixed effects were the two parameters and random effects were the participants' individual differences. Nearly the eighty percent of the variance of the smoothness evaluation score was explained by the linear model with the two key parameters and their interaction. The physical characteristics of a viewed object were far more significant than individual differences such as personality factors and the manner of art appreciation. In conclusion, the study examined the perception of smoothness based on the change of the physical characteristics of a shape. The study further recognized the relationship between smoothness and the aesthetic preference. No significant influence of the participants' individual difference such as gender, the degree in fine arts, personality factors, and the manner of art appreciation was observed. The amplitude of waves, rather than the number of them, was far more significant to the perception of smoothness.

The presnt study reviewed two contrasting models, fixed-resolution slot versus flexible-resource hypotheses, for the representational characteristics of visual working memory (VWM), and emphasized the necessary efforts for resolving their conflicting arguments. To accomplish this goal, the review explored the background hypotheses of the object-based versus parallel independent storage models, and introduced theoretical bases for their contrasting claims. The review then evaluated validity of empirical evidence provided in the studies to support each model, and attempted an understanding of their neurophysiological background. The study further emphasized the necessity of theoretical and methodological reconsiderations to resolve their conflict as well as the necessity of obtaining converging pieces of evidence to accomplish the resolution.

Animation has been developed as a part of artistry, and maintained a correlation with other various genres such as art, film and music to bring changes in form and to seek new things. Recently, technological advancement also has supported digitalization of producing process with variety in its method. Basic unit of animation production is a frame. A set of frames which has an image of producer's intention comes to life as animation when constructed, connected and transformed. A producer usually goes through a series of trouble when deciding how to express one's intention in images. Framing in animation is a kind of visual information which reflects producer's visual perception. A producer does not simply characterize matters into geometrical figures or give circumstantial explanation, but does framing work that relies on expression. Artistic psychology based on Gestalt Theory does not concentrate on abstract artistic philosophy with conventional beauty as its center, but pursues ambiguity and coherence of formative arts to support on accepting systematic order. Therefore, the purpose of this study is to find theoretical assistance which may be fundamental part in framing of animation. First, ten elements of Rudolf Arnheim centering on Gestalt Theory shall be redefined as concepts. Based on its ground, I will attempt to analyze shape-quality of framing of conventional animation, and make an approach with my personal experimental project. From this research project, I intend to analogize systematic aspect of framing in animation and to make framing of animation possible to assist in actual production of animation.

This paper describes a method for achieving a novel design within a class of 3D objects that would create a preferred impression on users. Physical parameters of the 3D objects that might strongly contribute to their visual impressions are sought through computational investigation of the impression ratings obtained for learning samples. "Car body" was selected as the class of 3D objects to be investigated. A morphable 3D model of car bodies that describes the variations in appearance using a smaller number of parameters was obtained. Based on each car body's rating for the impression of speediness obtained by paired comparison, the visual impression was transformed by manipulating the parameters defined in the morphable 3D model. The validity of the proposed method was confirmed by psychological experiments. A new scheme is also proposed to properly re-sample a novel object of a peculiar shape so that such an object could also be represented by the morphable 3D model.

Objective : This study is planned to determine the neurocognitive difficulties of hydrocephalic adults. Methods : The research group contained healthy adults (control group, n : 15), and hydrocephalic adults (n : 15). Hydrocephalic group consisted of patients with idiopathic aquaduct stenosis and post-meningitis hydrocephalus. All patients were followed with shunted hydrocephalus and not gone to shunt revision during last two years. They were chosen from either asymptomatic or had only minor symptoms without motor and sensorineural deficit. A neuropsychological test battery (Raven Standart Progressive Matrices, Bender-Gestalt Test, Cancellation Test, Clock Drawing Test, Facial Recognition Test, Line Orientation Test, Serial Digit Learning Test, Stroop Color Word Interference Test-TBAG Form, Verbal Fluency Test, Verbal Fluency Test, Visual-Aural Digit Span Test-B) was applied to all groups. Results : Neuropsychological assessment of hydrocephalic patients demonstrated that they had poor performance on visual, semantic and working memory, visuoconstructive and frontal functions, reading, attention, motor coordination and executive function of parietal lobe which related with complex and perseverative behaviour. Eventually, these patients had significant impairment on the neurocognitive functions of their frontal, parietal and temporal lobes. On the other hand, the statistical analyses performed on demographic data showed that the aetiology of the hydrocephalus, age, sex and localization of the shunt (frontal or posterior parietal) did not affect the test results. Conclusion : This prospective study showed that adult patients with hydrocephalus have serious neuropsychological problems which might be directly caused by the hydrocephalus; and these problems may cause serious adaptive difficulties in their social, cultural, behavioral and academic life.
