Multiplied Works, Open Work Seriality and Anonymity in the Cine-visual Research of the 1960s

Ways of presenting technological acoustic knowledge so as to awaken artistic sensibility to architectural students are explored, with emphasis on the acoustics of auditoria. The search is based on recent examples from modern architecture, where forms express in a highly artistic way the acoustical functions being served. There are also accounted, contemporary ideas about intrinsic communalities between musical composition (musical sound effect) and the architectural space, as well as the possibilities emerging from the introduction of modern psychometric methods to the research of audio and visual environmental perception. An audio visual example is employed to demonstrate the intrinsic relationships between musical composition and its visual aesthetic context.Ways of presenting technological acoustic knowledge so as to awaken artistic sensibility to architectural students are explored, with emphasis on the acoustics of auditoria.

IntroductionVisual perception is a fundamental skill that plays a central role in sensing the external environment. Deficits can lead to impairments in everyday activities. Visual perception is known to be impaired in Alzheimer’s disease (AD). However, the extent to which visual perception is impaired in mild cognitive impairment (MCI), often a prodromal state of AD, has not been sufficiently investigated. This study aims to assess visual perceptual abilities in people with MCI and mild AD compared with healthy controls. It will also investigate whether executive functions, activities of daily living and intelligence are affected in this context, providing new insights into the research of visual perception together with MCI and mild AD.Methods and analysisPeople with MCI, mild AD and healthy controls will be assessed for cognitive deficits using the Syndrom-Kurztest (SKT). Visual perceptual performance will be assessed using the German version of the Developmental Test of Visual Perception-Adolescent and Adult: Second Edition (DTVP-A:2; Frostings Entwicklungstest der visuellen Wahrnehmung – Jugendliche und Erwachsene 2. Auflage). Activities of daily living will be assessed through the Erlangen Test of Activities of Daily Living in Persons with Mild Dementia or Mild Cognitive Impairment (ETAM) and the Bayer Activities of Daily Living Scale (B-ADL). Executive functions will be measured using the German adaptation of the Behaviour Rating Inventory of Executive Function - Adult (BRIEF-A) and intelligence will be assessed using the Matrix Reasoning and Vocabulary Test of the Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV). Data analysis will involve descriptive analyses, linear regression analyses, multivariate analysis of variance, mediation analysis and structural equation modelling.Ethics and disseminationThis study has received approval from the Ethics Committee of Helmut Schmidt University/University of the Federal Armed Forces Hamburg, Germany (number: 2023_009). Findings will be disseminated through peer-reviewed publications and presentations at national and international conferences.Trial registration numberRegistered at OSF https://doi.org/10.17605/OSF.IO/PM5AV

본 연구는 국내학술지의 논문 중 고령자의 시지각에 관한 연구내용을 분석하여 고령자의 시지각 특성에 맞는 생활환경조성에 필요한 기초자료를 얻기 위하여 수행하였다. DBPIA의 고령자(노인)에 관한 연구 537편과 시지각에 관한 연구 40편, 그리고 한국노년학회지에 게재된 663편의 논문, 총 1,240편의 학술논문을 연구대상으로 삼아, 고령자의 시지각과 관련된 내용(노인, 고령자, 색채, 조명, 시각, 시지각)을 분석하였다. 그 결과, 고령자와 관련된 연구는 계속 증가하고 있으나 고령자 시지각과 관련된 연구는 매우 부족함을 알 수 있었다. 따라서 고령자의 시지각 특성을 파악할 수 있는 다양한 연구의 필요성이 제기되며 고령자가 자립적인 생활을 하는데 도움을 줄 수 있는 도구의 개발이나 생활환경의 디자인의 필요성을 밝히는 바이다.

We present a brief outline of the development of research in visual perception with the advent of new technologies up to New Media and virtual environments. There is a mutual inspiration and benefiting between fundamental and applied research and technological progress which should be utilized by the disciplines involved. Next, an overview of a conference, held in Nara (Japan) September 2001, is given of which different selections of articles are presented in the current special issues of the Swiss Journal of Psychology and of Japanese Psychological Research.

Research in visual perception has shown that in sensory areas, neural responses to a pair of objects presented together can be approximated by the linear average of the responses of each object shown alone. In this study, we ask if such an averaging relationship is unique to perceptual representations or if it also applies to representations maintained in visual working memory (VWM). By examining fMRI response pattern averaging across two experiments in both male and female human participants, we found that after properly accounting for task factors such as load, an averaging relationship also applies to representations formed in VWM. Specifically, VWM representations for two items can be approximated by the linear average of the VWM representations of each component item in both human occipitotemporal cortex (including early visual areas) and posterior parietal cortex. Although response averaging was originally proposed as a mechanism to combat distortion in representation due to neuronal response saturation in perception, the present study shows that even when response amplitudes were much lower in VWM compared with those in visual perception, an averaging relationship is still present for neural representations formed in VWM. This likely stems from the need to reduce interference among the concurrently stored items in VWM to maintain their representational independence. As an experimental method, response averaging may constitute an efficient yet simple tool to probe response independence in the human brain beyond perception and VWM.

Event Abstract Back to Event Visual perception of circular arcs and straight lines by simple interaction between edge pixels Wonil Chang1*, Suh-Yeon Dong2 and Soo-Young Lee2 1 Department of Bio and Brain Engineering, KAIST, Korea, Republic 2 Department of Electrical Engineering, KAIST, Korea, Republic The extraction of shape primitives such as lines and curves from images is an important problem in the research of visual perception. The mechanism of grouping edge components of image into curves has been extensively explored in previous studies on perceptual organization. Co-circularity is a tendency of edge pixels to lie on a curve with regular curvature, or a circular arc. Field et al. proposed association field [1], a visual cortex model that explains the perceptual organization based on co-circularity. Conventional biological models of curve extraction [2, 3, 4] are based on association field. However, they have shown limited ability to discriminate strict circular arcs from long and salient curves since association field is not tuned to specific curvature. We propose a novel visual cortex model that groups the detected edge pixels into circular arcs. The core of the proposed method is to overcome the limitation of association field in detecting circular arcs by adding delicate inhibitions and co-linearity constraints. An oscillatory network [5] with the proposed neural connectivity groups edge pixels on a circular arc by synchronization of neural oscillation. The proposed network is robust against clutters and partial damage of edge pixels in real images. In addition, slight modifications to the network enable to perceive random curves and straight lines. This work provides a computational model on how the interaction between low-level image elements builds up meaningful high level image representations in visual perception.

: The study objectives involve applying psychological knowledge of visual perception to improve real-time computer image generation (CIG) simulators. The primary objective is to suggest and identify CIG algorithms for visual simulation that improve the training effectiveness of CIG simulators. The secondary objective is to identify areas of basic research in visual perception that have a significant impact on improving CIG technology. The project proceeded in a sequence of three phases. The first phase entailed observing existing CIG simulators. During the second phase existing perceptual knowledge was studied in light of the capabilities and limitations of existing CIG simulators. In the third phase improved CIG algorithms were developed and relevant areas for further perceptual research were identified. (Author)

Visual perception refers to the process of organizing, identifying, and interpreting visual information in environmental awareness and understanding. With the rapid progress of multimedia acquisition technology, research on visual perception has been a hot topic in the academical field and industrial applications. Especially after the introduction of artificial intelligence theory, intelligent visual perception has been widely used to promote the development of industrial production towards intelligence. In this article, we review the previous research and application of visual perception in different industrial fields such as product surface defect detection, intelligent agricultural production, intelligent driving, image synthesis, and event reconstruction. The applications basically cover most of the intelligent visual perception processing technologies. Through this survey, it will provide a comprehensive reference for research on this direction. Finally, this article also summarizes the current challenges of visual perception and predicts its future development trends.

The use of simulation to degrade visual function is an essential tool in visual perception research. However, there are no standardised protocols for simulating different diseases and levels of impairment. Here, we explore various methods used to degrade visual function, inclusion criteria for selection based on participant’s baseline visual functions, and discuss potential advantages and limitations of each method. Methods such as spherical and toric lenses, Bangerter filters, fog filters, Cambridge simulation glasses, cataract glasses, prisms, and goggles for simulating visual field lesions are described. Their effects on visual functions, including visual acuity, contrast sensitivity, stereoacuity and visual field, are also discussed. Simulations may not always fully replicate true visual impairment, mainly due to age of onset of the disease, lack of adaptation to the specific visual condition, and the presence of multiple deficits in patients. Nevertheless, simulations allow the study of sudden and acute visual loss and short-term adaptation processes, and may contribute to developing improved rehabilitation strategies for patients with ophthalmic diseases.
