Objective : We try to show the necessity of crafts and arts comparing visual perception of autism with that of mental retardation using craft programmes. Methods : We applied a visual perception programme after sorting 10 autism and 10 mental retardation according to criteria. A used craft programmes are consulted and produced by specialist who are applying crafts as treatment or have experienced applying crafts. The items included potter, mobile art, wheat flour kneading, clay, corrugated cardboard work and color mix work. We applied the programmes twice a week during 4 weeks and used motor-free visual perception test-third edition(MVPT-3) to investigate the effect before and after treatments. Results : First, craft programmes had effect on both autism and mental retardation. Second, craft programmes had more effect on mental retardation. Conclusion : We could know that craft programmes influenced on visual perceptional development of autism and mental retardation.

This treatise deals with the profitable suit image design of middle-aged men by examining visual effects in physical design. The sample of this study is people who lives in Kwangju, the Republic of Korea and 20-50 age's men and women. And it is very variety in each population statistics factors the differences of associate design visual effect which considering the difference of sex and age group, numbers of button, a figure and material pattern. Firstly, look into the associate design visual effect by sex and button number. In men's group, the style with three buttons was the most attractive and that with two buttons was the least attractive. In 50's group, the style with two buttons was the least attractive and those with 1.3 and 4 buttons were a little attractive. Secondly, in the difference of associate design with sex and shape, men's group was considered that standard type was the most attractive shape, women's group was thought that lean and standard types were the most attractive shape. So we can know that the attractive shape is different with sex. In the difference of association design with age and shape, 20's considered that standard type was the most modernistic and fat type was the least modernistic. 30's considered that lean type was the most modernistic and 50's thought that fat type and standard type were the most modernistic. Thirdly, see the sex and material pattern. In familarity, men's group considered that stripe pattern was more familiar than checks and plain patterns. And they considered that striped pattern and plain was more manly than checks. In sex and material pattern, 20's thought that plain was the most attractive, stripe was the next, and checks was not attractive. 40's estimated that plain and stripe were more attractive than checks. 50's judged that stripe was the most attractive material. Thus. the attraction is different with ages and material patterns.

Background and Objectives: The influence of visual stimulus on the auditory component in the perception of auditory-visual (AV) consonant-vowel syllables has been demonstrated in different languages. Inherent properties of unimodal stimuli are known to modulate AV integration. The present study investigated how the amount of McGurk effect (an outcome of AV integration) varies across three different consonant combinations in Kannada language. The importance of unimodal syllable identification on the amount of McGurk effect was also seen. Subjects and Methods: Twenty-eight individuals performed an AV identification task with ba/ga, pa/ka and ma/ṇa consonant combinations in AV congruent, AV incongruent (McGurk combination), audio alone and visual alone condition. Cluster analysis was performed using the identification scores for the incongruent stimuli, to classify the individuals into two groups; one with high and the other with low McGurk scores. The differences in the audio alone and visual alone scores between these groups were compared. Results: The results showed significantly higher McGurk scores for ma/ṇa compared to ba/ga and pa/ka combinations in both high and low McGurk score groups. No significant difference was noted between ba/ga and pa/ka combinations in either group. Identification of /ṇa/ presented in the visual alone condition correlated negatively with the higher McGurk scores. Conclusions: The results suggest that the final percept following the AV integration is not exclusively explained by the unimodal identification of the syllables. But there are other factors which may also contribute to making inferences about the final percept.

In this study, we examined the effects of spatial attention in Hangul word recognition depending on visual factors. The visual complexity of words (Experiment 1) and contrast (Experiment 2) were manipulated to examine whether the effect of spatial attention differs depending on visual quality. Participants responded to words with and without codas in experiment 1 and words in high-contrast and low-contrast conditions in experiment 2. The effects of spatial attention were investigated by calculating the difference in performance between the condition where spatial cues were given at the target location (valid trial) and the condition where the spatial cues were not given at the target location (invalid trial) as the cuing effects. As a result, the cuing effects were similar depending on the complexity of the words. It indicates that the effects of spatial attention were not different across the visual complexity conditions. The cuing effects were greater in the low-contrast condition than in the high-contrast condition. The greater effect of spatial attention when the contrast is low was explained as a mechanism of signal enhancement.

Game graphics provide players with a sense of immersion, leading to active participation. This paper aims to analyze the mythological meaning for symbolic design of game skill visual effects that reproduce the narrative and the worldview of games borrowing myths. The research method classified the visual effect image into a symbol of the form of a universal archetype representation and a symbol of color expressing the narrative in the game, and analyzed it by applying Roland Barthes' semiological scheme. Through this study, it was possible to analyze the meaning of visual effects as a mythical meaning that can be universally sympathized and an implicit meaning that symbolizes the narrative of the game. The symbolic expression of the visual effect, which reproduces the narrative of the game reflecting the myth, can induce players to engage and participate, and the design direction was intended to provide the visual effect to have a unique symbolism that reflects the game's mythical worldview of the game.

This study was to investigate the effect of EEG wave type of visual cortex on conjugate movement of eyeball according to movement of visual target. Visual evoked potential(VEP) system used the Bio-Pag(production in USA) and recorded to 586 computer. The illumination of test room was 50lux and the visual target was red light dot of 3cm size. The results of dextroversion and levoversion as follows : The visual stimulation waves on the visual cortex have about 71% of delta wave, about 12% of beta wave, about 9% theta wave and about 6% of alpha wave respectively. The dextroversion and levoversion state was similar results on the histogram amplitude of EEG wave, frequency of EEG wave type, EEG wave style and phase diagram of amplitude. Expecially the histogram amplitude of EEG wave appeared almost the Gaussian shape and the phase analysis of amplitude of EEG wave was nearly linear shape. On the fast fourier transform of the amplitude and Hz, the frequency was almost low frequency under 20 Hz, and the dextroversion and levoversion shape was similar results.

In the digital media era, coded and non-coded communication are used to convey the message. As the computer interface has been adopted human communication methods, non-coded communication has bee used in the computer interface as well. The changes of message structure in the computer interface have an effect on shifting the way of user's message acceptance from passive to active. The recently developed computer user interfaces are for user to experience diverse visual effect The communication conveyed with this visual effects could be vague but user can conceive strong impact. This experience is understood not only through the visual experience from a monitor screen but also with a sense of tactile. The meaning of sensual and spectacle motion image could be ambiguous. However in the experience of using an interface, it plentifully expands the human sense by giving a visual experience on a whim. The sensually extemporaneous and splendid visual effect that has vague meaning has been very common happening in digital media environment.
