The ipsilateral dorsal lobe of the brain one or two days after cutting a left antenna in Pieris rapae has been examined with electron microscope to investigate the connection of the receptor cells between antenna and dorsal lobe. The proximal removal of the left antenna leads to the weakly-dark, semidark or dark degeneration of antennal receptor tenninals in ipsilateral dorsal lobe. Therefore, it is concluded that some of antennal receptor cells which project into the brain terminate in ipsilateral dorsal lobe located immediately behind the antennal lobe.

This study tries to investigate the relationship between physical perception and creative thinking of dancers by dance imagery training programs. The inner imagery and the external expression of dancers are a divergent expression process of autosuggestion, and substantiate the relationship between physical perception and creative thinking. The key point consists in the active thinking process of problem recognition and problem solving by imagination, and means a new perceptivity and the communication capability. Dance imagery is a perception training based on the integration principle of body and soul, and so dancers should create a new approach of communication through the diversity of wide inner imagination and the active thinking of external expression.

To analyze a room reverberation, many objective parameters have been suggested as measures of subjective perception in concert hall acoustics. However, it is difficult to understand the relationship among the individual parameters and to have a whole image of them. In this paper five primary objective parameters were selected and a reverberation model based on them was established by the reverberation decay curve. The proposed model was interpreted geometrically in terms of subjective characteristics. And finally we discuss the usefulness and the limitation of the model when it is applied to the analysis and.

Nowadays, some movie theaters provide additional sensory information in 3D movies to enhance visually induced motion perception. However, no studies have investigated how motion perception increases. Thus, in this study, we examined the effect of visual coherent sensory information on visually induced motion perception and quantification of sensory information. A visual stimulus rotated sinusoidally and visual coherent sensory information were applied as vibrations to a subject's foot. We measured the sway of the subject's body by using a force plate and somatosensory bar rotation that represents the subject's perception of the horizon using an encoder. By using this data, we obtained the weight of the sensory information using a Kalman filter. As a result, it was found that subjects rotated the somatosensory bar more when visual coherent vibrations were applied. The weight of vision also increased when visual coherent vibrations were applied. Thus, we can conclude that visual coherent sensory information tends to enhance visually induced motion perception and weight of vision.

Perception refers to the process of acquiring all the information about the environment through various sensory organs such as the visual, auditory, tactile, and olfactory senses and integrating and interpreting the information transmitted to the brain. The ability to use these perceptions efficiently is called perceptual skill, and perceptual skill is an important factor for improving performance in the field of sports. As a result, many researchers have developed various perceptual training programs to maximize these perceptual skills while they have also progressed on attempting to verify their effects. The perceptual skill training introduced in this study is a training method that focuses on visual perception and is a training method that is applied in the United States and Europe. to improve sports performance. As a result of carrying out the perceptual skills training based on the kicker's important clue (the kicker's hip - the angle of the body and foot before kicking) to the goalkeeper in the situation of a soccer penalty kick improved the ability of predicting the direction of the ball while even in tennis, carrying out the perceptual skills training based on the server's important clue (position, ball, racket) improved the accuracy of the ability to predict in the direction of serve. Recently, there have been numerous research studies that were carried out on such perceptual skills training, but the number of studies conducted are insufficient, especially in Korea where research studies on perceptual training seem to be in a relatively neglected state. In addition, extensive studies need to be carried out to investigate whether the improvement of perceptual skills in the laboratory situation can be transitioned to an actual performance situation. Therefore, in order to elevate sports performance, researchers need to examine the perceptual training program's extent of necessity as well as the research direction regarding its effects.

We used holes defined by color similarity (Experiment 1) and binocular disparity (Experiment 2) to study how the inner contour of an object (i.e., boundary of a hole in it) is encoded in visual working memory. Many studies in VWM have shown that an object's boundary properties can be integrated with its surface properties via their shared spatial location, yielding an object-based encoding benefit. However, encoding of the hole contours has rarely been tested. We presented objects (squares or circles) containing a bar under a change detection paradigm, and relevant features to be remembered were the color of objects and the orientation of bars (or holes). If the contour of a hole belongs to the surrounding object rather than to the hole itself, the object-based feature binding hypothesis predicts that the shape of it can be integrated with color of an outer object, via their shared spatial location. Thus, in the hole display, change detection performance was expected to better than in the conjunction display where orientation and color features to be remembered were assigned to different parts of a conjunction object, and comparable to that in a single bar display where both orientation and color were assigned into a single bar. However, the results revealed that performance in the hole display did not differ from that in the conjunction display. This suggests that the shape of holes is not automatically encoded together with the surface properties of the outer object via object-based feature binding, but encoded independently from the surrounding object.

With the widespread adoption of mobile devices, such as smart phones and smart pads, as well as the rapid growth of mobile technologies, consumer shopping patterns are changing. This study investigates key factors of consumer purchasing intention in a mobile shopping mall context by incorporating trust belief into the theory of planned behavior. We posit perceived usefulness, perceived enjoyment, perceived ease of use, and trust belief as antecedents of behavioral attitude toward mobile shopping malls. Moreover, social influence and security are identified as key enablers of trust belief on mobile shopping malls. Data collected from 154 consumers with purchasing experience in mobile shopping malls are empirically tested against a research model using partial least squares. Analysis results show that behavioral attitude and perceived behavioral control significantly influence purchasing intention. Moreover, this study reveals the significant effects of perceived usefulness and perceived enjoyment on behavioral attitude. Trust belief indirectly influences purchasing intention through behavioral attitude and is significantly affected by social influence. Understanding consumer purchasing decision-making processes in mobile shopping malls can help service providers to develop effective marketing and operation strategies and campaigns.

시각 자극의 운동 방향을 파악하는 것은 시각의 주요 기능 가운데 하나이다. 동일한 망막상의 영상 운동은 다양한 조합의 시각 자극의 운동 벡터와 눈 운동의 벡터의 합으로 발생할 수 있는데, 이렇게 망막 정보가 애매한 경우에도 불구하고 시각 자극의 움직임을 정확하게 파악하며, 이것은 시지각의 안정성을 돕는 망막 이외의 정보가 통합된 결과이다. 본 발표는 이러한 정보 중에 하나인 도약 안구 운동에 즈음하여 제시되는 시자극 운동의 지각 과정에서 안구 운동 정보의 역할을 결정한 실험의 결과에 관한 것이다. 도약 안구 운동의 발생 전후에 제시된 자극의 속성에 대한 판단은, 자극의 속성과 도약 안구 운동 방향에 따라 일정한 방식으로 조절되는 것을 관찰하였다. 이러한 시각 운동의 지각 왜곡을 일으키는 신경 기전은 일차 시각 피질에서 일어날 가능성이 있는 것으로 생각된다.
