visual perception

Executive functions and visual perception are variables that play important roles in learning and educational improvement. Therefore, the aim of this study was to investigate the effectiveness of attention rehabilitation on executive functions and visual perception of students with learning disorder and the study was of quasi - experimental type with pre-test, post-test and control group. The statistical population included all elementary school students in Rafsanjan in the second semester of 2018. The sampling method was multi-stage cluster method and the statistical sample of research involved 20 students with specific learning disorders, selected and replaced by a simple random method in two groups of experiment and control groups (2 groups of ten). The research tools were the visual perception test of Frostig and the Wisconsin cards. After performing pre-test on both control and experimental groups, the experimental group was trained using Captain Log software for 12 session, and at the end, the post-test was performed on both groups. The data were analyzed using SPSS v.24 software and statistical analysis of covariance (MANCOVA). The results of statistical analysis showed that attention facilitator rehabilitation is effective in improving students' ability in visual perception test. Also, the results revealed that rehabilitation of attention can significantly improve the performance of children with learning disorder in the executive functions.

The ability to recognize and compare shapes and understand the concept of proportions is one of the first human findings from environmental geometric data. And certainly the formation of geometry as a science of recognizing the arrangement of lines, shapes and levels and proportions leads to the definition of golden proportions in the mathematical sciences as a new way of organizing shapes and forms. Golden and geometric proportions are effective as a determining element in the scale of spatial forms, and the formation of spatial forms by not using or misuse of geometric proportions is due to functional and psychological interactions on human perception and cognition. Which causes the construction and formation of scales and proportions of the environment and the emergence of psychological effects due to human activities in the environment. And then the abnormal effects and environmental dysfunction on the saccade system of the human eye and as a result the feeling of fear and lack of belonging to the place interacts. On the other hand, nature as the raw material of creation, and the principle and mother of man, which causes him to model the proportions in nature. Understanding the laws governing the relationships between elements and spatial shapes leads to the formation of geometric and golden proportions in the spending of space. Because knowing the symbol of shapes, proportions and scales in the world of meaning and kingdom is reminiscent of the divine order in all dimensions of the world (even in astronomy). Therefore, evaluating the values ​​of spatial proportions in nature as the bedrock of human life and the pattern of psychological perceptions, leads to the adoption of human activities. Also, the study of human needs on a mental and psychological scale from the perception of the environment causes the recognition of scales and dimensions by human visual senses, which leads to the perception of the correct golden and geometric proportions through Sakadi eye movements and psychophysical sciences. . Certain ratios can also be observed in the creation and design of various shapes in nature. These relations are those geometric relations that have immaterial roots and follow the spiritual and supernatural principles, believing that their subject is sacred, and have a symbolic language and spiritual characteristics. In the traditional world, geometry was inseparable from the other four Pythagorean sciences, namely arithmetic, music, and astronomy. And traditional geometry is also associated with the symbolic composition and shapes of space. To this end, the study of the effect of golden and geometric proportions on human visual perception of the architectural environment based on the sense of belonging to the place, causes visual quality to increase the sensory richness of the place and achieve human values ​​and criteria in the sense of belonging to the place and human needs. To be considered by the architect. In this research, with the perspective of this identity and the interaction of geometric and golden proportions and the sense of belonging to the place, the criteria and indicators of the research have been studied and the results have been presented in the form of tables and diagrams.

In recent years, the quality of transitional spaces in residential complexes has emerged as a crucial factor in helping residents find their way and improving their overall spatial experience. To fill a gap in existing research, this study investigated how these spaces influence wayfinding based on visual perception in District 6 of Shiraz. using a mixed-method approach, the research sought to answer two central questions: (1) Which visual perception components are key to wayfinding? and (2) How does the spatial layout of transitional areas affect wayfinding quality? In the qualitative phase, the research team identified core components through a detailed content analysis. For the quantitative phase, they surveyed 378 residents from nine selected complexes, using a questionnaire they had developed. the statistical analysis revealed that the average scores for environmental (2.65), human (2.72), and visual field (2.94) variables were all below optimal levels. The results also confirmed significant differences across various residential types, with lower scores found in complexes that had more blocks. Among the visual indicators, "environmental cues" (mean rank 3.76) and "spatial extent" (3.37) were the most influential, while factors like "enclosure" and "curvilinearity" had minimal impact. ultimately, a balanced combination of environmental factors (form, light, color, signage), human factors (accessibility, safety, social vitality), and visual factors (openness, field of view) is essential for improving legibility, safety, and ease of navigation. These findings offer practical guidance for designers to create residential interface zones that are more legible and easier to navigate.

Background: Understanding how humans perceive and estimate distances in built environments is critical not only for advancing perceptual psychology but also for informing the design of computational models in computer vision, robotics, and architectural design. Aims: This study investigates the mechanisms and limitations of human distance estimation within a controlled architectural environment. Methodology: While some previous experiments focused on estimating distances in virtual settings, the current study examines real-world estimation accuracy across a series of predefined points within an unobstructed corridor. Participants were asked to visually estimate the distance between their position and seven distinct target locations, ranging from near to far without the aid of physical reference cues. The core objective was not simply to measure accuracy, but to identify the perceptual threshold beyond which estimation errors significantly increase. A one-way ANOVA model was employed to assess the influence of variables such as actual distance and participant age on perceptual accuracy. Results: Results revealed a consistent estimation performance up to approximately 2 m, beyond which the margin of error grew increasingly pronounced. Notably, a critical threshold was identified at 7.476 m, where estimation errors sharply escalated. The maximum observed discrepancy occurred at a distance of 10.186 m, suggesting a cognitive boundary in spatial awareness. Conclusion: These findings contribute to the understanding of visual-spatial perception mechanisms and offer theoretical insights relevant to applications in robotics, image processing, virtual reality, and navigation system design.
