GRAPHOMOTOR SKILLS IN PRESCHOOL-AGED CHILDREN

Mastering writing skills is preceded by a significant developmental pathway of graphomotor abilities, which starts early in childhood. Considering that graphomotor ability and visual perception are prerequisites for mastering the writing, this study analyzed the graphomotor abilities in preschool-aged children, with the aim of identifying children exhibiting elements suspected of dysgraphia. The sample consisted of 100 preschool-aged children (age 5-6), of both genders (49 girls and 51 boys). Pre-writing skills were assessed using the Predictive Test for Dysgraphia. The research was conducted in a Preschool Institution in Danilovgrad, in March and April 2024. The results of analysis showed that preschool-aged children have specific difficulties in meeting the following criteria: accurately following the given sequence of figures and their careful and precise drawing (size and shape). It was also found that children of this age group have a particular problem in maintaining the specified distance of the figures from the edge of the rectangle (drawing around the edge). The only test item that the majority of respondents were able to respond to was perseverance in completing tasks, in terms of finishing the drawing (a series of started figures). Based on inadequate visual discrimination of the size and shape of given and drawn figures, and poor spatial orientation on paper, it is possible to identify children with graphomotor difficulties. Early detection of children with visual-perceptual and graphomotor difficulties will help overcome these deficiencies through systematic exercises through speech therapy treatments, so that children can start school being better prepared.

Light-Adapted Optoelectronic-Memristive Device for the Artificial Visual System.

With the development of artificial intelligence systems, it is necessary to develop optoelectronic devices with photoresponse and storage capacity to simulate human visual perception systems. The key to an artificial visual perception system is to integrate components with both sensing and storage capabilities of illumination information. Although module integration components have made useful progress, they still face challenges such as multispectral response and high energy consumption. Here, we developed a light-adapted optoelectronic-memristive device integrated by an organic photodetector and ferroelectric-based memristor to simulate human visual perception. ITO/P3HT:PC71BM/Au as the light sensor unit shows a high on/off ratio (Iph/Id) reaching ∼5 × 104 at 0 V. The memristor unit, consisting of ITO/CBI@P(VDF-TrFE)/Cu, has a RON/ROFF ratio window of ∼106 under 0.05 V read voltage and ultralow power consumption of ∼1 pW. Moreover, the artificial visual perception unit shows stable light-adapted memory windows under different wavelengths of irradiation light (400, 500, and 600 nm; they meet the spectral range of human visual recognition) and can clearly identify the target image ("T" shape) because of the apparent contrast, which results from the high ROFF/RON ratio values. These results provide a potential design strategy for the development of intelligent artificial vision systems.

No such thing as the female eye: ditching gender-binary categories in art perception

ABSTRACT We still know little about whether and how gender informs, shapes, or influences art perception. This multidisciplinary article investigates the role that gender might play in the perception of art through historical analyses and an eye-tracking experiment. We first traced how gender identity, sexual identity, and sexual orientation have been used to theorize the existence of a gender-binary difference between viewers in traditional aesthetics and feminist art theory. To test whether such claims reflect any measurable experience, we collected eye-tracking data from 84 participants and divided them into two groups of cisgender, heterosexual individuals by self-definition. Each group participated in two experiments; the first showed digital reproductions of mixed artworks, varying in subject, style, form, and size; the second showed artworks with only one figure, either explicitly showing sex-linked traits or not. In both cases, we measured the number of fixations, average fixation duration, and saccade amplitude as well as differences in the location of fixations and entropy. Our analysis did not detect any significant difference between the groups. This proves empirically, for the first time, that in spite of having been often reiterated in history, gender binary categories are not suitable for describing the visual perception of art.

Evaluating Activation Functions in GAN Models for Virtual Inpainting: A Path to Architectural Heritage Restoration

Computer vision has advanced much in recent years. Several tasks, such as image recognition, classification, or image restoration, are regularly solved with applications using artificial intelligence techniques. Image restoration comprises different use cases such as style transferring, improvement of quality resolution, or completing missing parts. The latter is also known as image inpainting, virtual image inpainting in this case, which consists of reconstructing missing regions or elements. This paper explores how to evaluate the performance of a deep learning method to do virtual image inpainting to reconstruct missing architectonical elements in images of ruined Greek temples to measure the performance of different activation functions. Unlike a previous study related to this work, a direct reconstruction process without segmented images was used. Then, two evaluation methods are presented: the objective one (mathematical metrics) and an expert (visual perception) evaluation to measure the performance of the different approaches. Results conclude that ReLU outperforms other activation functions, while Mish and Leaky ReLU perform poorly, and Swish’s professional evaluations highlight a gap between mathematical metrics and human visual perception.

Supporting Infants’ Motor Development through Water Activities: A Preliminary Case–Control Study

The first twelve months of an infant’s life are the most dynamic time in the development of motor activities. Water activities can positively stimulate the motor skills, visual perception, and cognitive abilities of infants. The purpose of this study was to evaluate the motor development of infants aged 3–12 months participating in water activities. Participants in the study included 43 infants aged 3–12 months who attended water activities classes at Warsaw City swimming pools (n = 21) and infants not attending any classes (n = 22). Two methods of assessing motor development were used in the study: the Alberta Infant Motor Scale (AIMS) and the Early Motor Development Questionnaire (EMQ). The raw scores of the AIMS test and the EMQ questionnaire were statistically significantly different (p < 0.05) in both groups between the first and second examinations. In contrast, there was a statistically significant improvement in motor development measured by AIMS and expressed in percentiles (p = 0.002) and in percentiles for Polish children (p = 0.030) in the water group. The age-independent total score of the EMQ before and after the intervention did not change significantly (p = 0.149). The water environment has the potential to support the motor development of infants aged 3–12 months.

Distinct neural plasticity enhancing visual perception.

The developed human brain shows remarkable plasticity following perceptual learning, resulting in improved visual sensitivity. However, such improvements commonly require extensive stimuli exposure. Here we show that efficiently enhancing visual perception with minimal stimuli exposure recruits distinct neural mechanisms relative to standard repetition-based learning. Participants (n=20, 12 women, 8 men) encoded a visual discrimination task, followed by brief memory reactivations of only five trials each performed on separate days, demonstrating improvements comparable to standard repetition-based learning (n=20, 12 women, 8 men). Reactivation-induced learning engaged increased bilateral intra-parietal sulcus activity relative to repetition-based learning. Complementary evidence for differential learning processes was further provided by temporal-parietal resting functional connectivity changes, which correlated with behavioral improvements. The results suggest that efficiently enhancing visual perception with minimal stimuli exposure recruits distinct neural processes, engaging higher-order control and attentional resources, while leading to similar perceptual gains. These unique brain mechanisms underlying improved perceptual learning efficiency may have important implications for daily life and in clinical conditions requiring re-learning following brain damage.Significance Statement The adult human brain shows remarkable plasticity resulting in improved visual perception following practice. Here, we document a distinct neural pathway in the human brain, supporting enhanced perceptual learning efficiency. These unique neural mechanisms are triggered by brief memory reactivations, which replace prolonged repetition-based stimuli exposure to enable enhanced visual perception. The results suggest that efficiently enhancing visual perception with minimal stimuli exposure distinctively engages higher-order control and attentional resources, while leading to similar behavioral gains. Evidence for differential offline learning processes was further provided by resting functional connectivity changes. The findings shed light on unique brain mechanisms underlying improved perceptual learning efficiency, and may have important implications for daily life and in clinical conditions.

Grace, too: the sense of agency and Jeremy Safran's relational vision.

The sense of agency, our felt sense of authorship for our actions, is a difficult concept to define, yet its faltering stands at the heart of psychopathology. Historically undertheorized by psychoanalysis and typically positioned opposite relatedness by clinical psychology, Jeremy Safran conceived of agency and relatedness as paradoxically related. This paper pays tribute to Safran's ideas by taking his writings on agency as a starting point to elaborate how agency forms, and goes awry, in the relational crucible of early life. In doing so, the paper draws on the developmental theory of Winnicott, empirical research on embodied agency from adjacent fields of study, and Safran's clinical phenomenology.

Achieving Image Encryption Quantum Dot-Functionalized Encryption Camera with Designed Films.

The risk of information leaks increases as images become a crucial medium for information sharing. There is a great need to further develop the versatility of image encryption technology to protect confidential and sensitive information. Herein, using high spatial redundancy (strong correlation of neighboring pixels) of the image and the in situ encryption function of a quantum dot functionalized encryption camera, in situ image encryption is achieved by designing quantum dot films (size, color, and full width at half maximum) to modify the correlation and reduce spatial redundancy of the captured image during encryption processing. The correlation coefficients of simulated encrypted image closely apporach to 0. High-quality decrypted images are achieved with a PSNR of more than 35dB by a convolutional neural network-based algorithm that meets the resolution requirements of human visual perception. Compared with the traditional image encryption algorithms, chaotic image encryption algorithms and neural network-based encryption algorithms described previously, it provides a universal, efficient and effective in situ image encryption method.

The influence of affective voice on sound distance perception.

Affective stimuli in our environment indicate reward or threat and thereby relate to approach and avoidance behavior. Previous findings suggest that affective stimuli may bias visual perception, but it remains unclear whether similar biases exist in the auditory domain. Therefore, we asked whether affective auditory voices (angry vs. neutral) influence sound distance perception. Two VR experiments (data collection 2021-2022) were conducted in which auditory stimuli were presented via loudspeakers located at positions unknown to the participants. In the first experiment (N = 44), participants actively placed a visually presented virtual agent or virtual loudspeaker in an empty room at the perceived sound source location. In the second experiment (N = 32), participants were standing in front of several virtual agents or virtual loudspeakers and had to indicate the sound source by directing their gaze toward the perceived sound location. Results in both preregistered experiments consistently showed that participants estimated the location of angry voice stimuli at greater distances than the location of neutral voice stimuli. We discuss that neither emotional nor motivational biases can account for these results. Instead, distance estimates seem to rely on listeners' representations regarding the relationship between vocal affect and acoustic characteristics.

Research on visual experience evaluation of fortress heritage landscape by integrating SBE–SD method and eye movement analysis

Urbanization has led to homogenizing heritage site landscapes, and the protective measures have become disconnected from public needs. Additionally, the complex and diverse overall characteristics of heritage sites and the uneven distribution of values across different areas are related to the lack of landscape experience assessment. The “subjective + objective” cognitive evaluation and visual perception framework that adopts the Scenic Beauty Estimation Procedure-Semantic Differential (SBE–SD) method and eye-tracking analysis can compensate for the limitations of a single evaluation method by integrating quantitative and qualitative analysis. This research takes the Yi’an Fortress in Zhangpu County, Fujian Province, as the object and examines the visual experiences of different areas and types of landscapes within the Yi’an Fortress. The findings reveal several key insights: (1) Significant differences were found in the landscape experiences of different areas within the heritage site. The visual experience score of the core building area of Yi’an Fortress is (1.01) > the heritage entrance area (0.897) > the residential area (0.841) > the natural ecological area (0.784), indicating that the natural ecological area should be the focus of future protection and development efforts, with a particular emphasis on enhancing the ‘landscape aesthetic’ and ‘landscape cultural’ aspects. (2) The landscape experience scores can be used to understand the reasons for the differences in participants’ experiences of different landscapes. The architectural heritage landscape of the Yi’an Fortress scored highest in the experience evaluation due to its superior performance in terms of ‘landscape form’ factors. The cultural decorative landscape scored next, while the garden greening landscape scored the lowest, due to their poorer performance in terms of ‘landscape form’ and ‘landscape aesthetics’. (3) The eye-tracking data was consistent with the results of the subjective evaluation, validating the “subjective + objective” cognitive evaluation and visual perception framework, employing the SBE–SD method and eye-tracking analysis is a scientific and effective method for assessing the visual experience of heritage landscapes. These results provide a scientific basis for the heritage planners and managers of the Yi’an fortress to improve the landscape environment, better meet public needs, and preserve the unique character of this vital cultural resource. Furthermore, this study offers a new research method and approach for the protection of other heritage landscapes.

Feature binding is slow: Temporal integration explains apparent ultrafast binding.

Visual perception involves binding of distinct features into a unified percept. Although traditional theories link feature binding to time-consuming recurrent processes, Holcombe and Cavanagh (2001) demonstrated ultrafast, early binding of features that belong to the same object. The task required binding of orientation and luminance within an exceptionally short presentation time. However, because visual stimuli were presented over multiple presentation cycles, their findings can alternatively be explained by temporal integration over the extended stimulus sequence. Here, we conducted three experiments manipulating the number of presentation cycles. If early binding occurs, one extremely short cycle should be sufficient for feature integration. Conversely, late binding theories predict that successful binding requires substantial time and improves with additional presentation cycles. Our findings indicate that task-relevant binding of features from the same object occurs slowly, supporting late binding theories.

Application of Video Abnormal Behavior Detection Algorithm in Evaluation of Track and Field Teaching and Training Effect

With the development of track and field, people pay more and more attention to the quality of classroom teaching of track and field technology, and the evaluation of teaching quality plays a key role in it. In today's educational reform, teaching evaluation plays an important role as an important method to test teachers' teaching and students' learning. With the rapid development of machine learning, especially deep learning, image-based individual abnormal behavior detection technology is becoming more and more mature, but there are still many difficulties to be solved in video-based group abnormal behavior detection technology. Therefore, it is necessary to study the detection algorithm. Based on machine vision theory, image processing theory and video analysis technology, this paper studies three key technologies involved in human abnormal behavior detection in video: moving target detection, moving target tracking and abnormal behavior detection.

Mediatized Eurocentric Beauty Ideals and their Effects on African Women: Demystifying the Moroccan Context

This research investigates the profound influence of Eurocentric beauty ideals, propagated predominantly through mainstream media, on the self-perception and body image of Moroccan women. Focusing on a sample of 134 females, the study examines how exposure to these ideals through media outlets, such as television, and social media impacts beauty and self-perception. The findings highlight several critical dynamics. Firstly, there is a significant negative correlation between high exposure and both self-esteem and body image, indicating that greater consumption of Western media is associated with lower self-esteem and more negative body image perceptions. Secondly, our research reveals that Moroccan women experience substantial pressure from social media as well as their inner circle to conform to certain beauty standards, which adversely affects their psychological health and perception of beauty. Finally, the study identifies age and education as significant moderators in how media exposure affects women, suggesting that these factors may offer some resilience against the negative impact of media. These insights underscore the need for a broader representation in media to foster healthier self-perceptions and challenge the dominance of Eurocentric beauty standards.

Effect of an acute bout of exercise on executive function and sleep in children with attention deficit hyperactivity disorder and autism spectrum disorder

Background and aimsThe present study aimed to examine the effect of an acute bout of circuit-base exercise on executive function, visual perception and sleep parameters in neurodiverse children. MethodsAfter familiarisation, 34 children (4 female) with ADHD and/or ASD completed two trials (30-min circuit-based exercise (E) or a rested control (C) trial) in a randomised, counterbalanced, crossover design. Participants completed cognitive function tests (Stroop test, Sternberg Paradigm and Visual Search Test) at baseline, immediately post-exercise, and the morning after exercise. Participants were provided with a wrist actigraph to wear overnight to determine sleep duration, wake after sleep onset, sleep efficiency, and sleep latency. Statistical analyses were conducted via ANCOVA, with diagnosis included as a covariate. ResultsAccuracy on the Stroop test (complex level) was better maintained following circuit-based exercise when compared with rest immediately post-exercise (E: 1.88% decreased accuracy; C: 4.73% decreased accuracy, p = 0.009), and on day two (E: 1.22% increased accuracy; C: 6.37% decreased accuracy; p < 0.001). Accuracy on the Sternberg Paradigm (5-item level) was improved immediately post-exercise on the exercise trial when compared with rest (E: 0.37% decreased accuracy; C: 7.29% decreased accuracy; p = 0.011). Improvements in accuracy across both tests were at the expense of response time, which was slower on the exercise trial (all p < 0.05). Sleep parameters did not differ across trials (all p > 0.05). ConclusionModerate intensity circuit-based exercise is an ecologically valid exercise modality that, acutely, improves executive function (compared to rest), which may alleviate the impaired executive function in children with ADHD and ASD.

Few-shot bronze vessel classification via siamese fourier networks

Exploring ancient Chinese artifacts is crucial for analyzing East Asian technological development, with bronze vessel being the critical element. Bronze vessels, typically featuring intricate carvings, hold historical significance and provide valuable insights into past civilizations. However, identifying bronze patterns can be challenging for human vision, and most RGB-domain methods fail to capture periodic designs. Addressing these issues, we propose the Siamese Fourier Networks (SFN), a parallel network model designed for few-shot regular pattern classification. The Siamese network can differentiate between intricate shapes, while Fourier features enable the extraction of regular textures. To optimize parallel networks, we combine the BCE loss and focal contrastive loss, balancing positive and negative samples. Moreover, we introduce the Bronze Vessel Dataset, featuring 527 samples with diverse shapes and unbalanced distributions. Extensive experiments with advanced few-shot methods demonstrate the superiority of SFN and focal mechanism, significantly improving accuracy.

Sound symbolic associations: evidence from visual, tactile, and interpersonal iconic perception of Mandarin rimes

Sound symbolism refers to the non-arbitrary relationship between phonemes and specific perceptual attributes. Few studies have focused on the sound symbolic associations between Mandarin phonemes and multiple perceptual dimensions, including social attitudes. The main purpose of the current study is to identify the acoustic cues crucial to perceptual judgment on the visual, tactile, and interpersonal dimensions based on the Mandarin rimes. The study found that in addition to the first and second formants, formant transitions and nasal codas were crucial in characterizing sound symbolic associations. Machine learning models also showed that critical acoustic parameters could successfully classify the different perceived attributes of rimes. The study further examined the mechanisms underlying forming a sound symbolic association. Through mediation analyses, the light/heavy dimension proved to have a suppression effect on the politeness and friendliness perception of Mandarin compound rimes (diphthongs and diphthongs with nasal codas /n/ or /ŋ/). This finding suggested that the two potential mechanisms of sound symbolism (i.e., language pattern account and shared-property account) could coexist and interact with each other.

Are increased symptoms of orthorexia nervosa linked to self-perceived body image and nutritional adequacy of Turkish adults?

ABSTRACT This cross-sectional study, conducted on 4003 participants aged between 18 and 45, aims to contribute to orthorexia nervosa (ON) research by examining the relationship between ON, body image and nutritional adequacy. The Orthorexia Nervosa-11 scale (ORTO-11) and body perception scale were applied to individuals, and food consumption records were taken with a 24-hour dietary recall method. The study found that more individuals with orthorexia nervosa (ON) considered themselves overweight compared to non-ON individuals. Evaluating diet quality, the mean adequacy ratio was significantly higher in ON individuals. Nutrient adequacy ratios for total fiber, magnesium, zinc, thiamine, folic acid, and vitamin C were higher, while those for carbohydrate and iron were lower in ON individuals. Additionally, increasing the number of snacks, protein, and total fiber adequacy decreased the ORTO-11 score. Distorted body image perception may be a risk factor for ON, but healthy eating fixation does not lead to nutrient inadequacy unless it involves progressive food restriction.

Open-Ended Online Learning for Autonomous Visual Perception.

The visual perception systems aim to autonomously collect consecutive visual data and perceive the relevant information online like human beings. In comparison with the classical static visual systems focusing on fixed tasks (e.g., face recognition for visual surveillance), the real-world visual systems (e.g., the robot visual system) often need to handle unpredicted tasks and dynamically changed environments, which need to imitate human-like intelligence with open-ended online learning ability. Therefore, we provide a comprehensive analysis of open-ended online learning problems for autonomous visual perception in this survey. Based on "what to online learn" among visual perception scenarios, we classify the open-ended online learning methods into five categories: instance incremental learning to handle data attributes changing, feature evolution learning for incremental and decremental features with the feature dimension changed dynamically, class incremental learning and task incremental learning aiming at online adding new coming classes/tasks, and parallel and distributed learning for large-scale data to reveal the computational and storage advantages. We discuss the characteristic of each method and introduce several representative works as well. Finally, we introduce some representative visual perception applications to show the enhanced performance when using various open-ended online learning models, followed by a discussion of several future directions.

Traffic Sounds in Office Spaces: PLS-SEM Study on Audio-Visual Perception with Open or Closed Windows and Biophilic Design.

Herein, we investigated the audio–visual perception of indoor greenery and intruding traffic sounds through open or closed windows in a shared office context that accommodates two people. A set of 32 audio–visual stimuli was used, featuring combinations of greenery dosages (0%, 7%, 10% and 13%) and traffic sound levels (50 dBA, 55 dBA, 60 dBA and 65 dBA) , for both open and closed windows. These stimuli were presented to 42 participants in an indoor office environment using two-dimensional screens and over-ear headphones. We employed a partial least squares structural equation model to integrate greenery dosages, traffic sound levels and perceptual attributes such as pleasantness, eventfulness, appropriateness, preference and visual aesthetics. The findings demonstrate the impact of traffic sound levels on visual perception, highlighting a bidirectional interaction between auditory and visual perceptions. Indoor greenery indirectly enhances the pleasantness of the auditory environment, supporting the implementation of biophilic design in office spaces that are visually appealing and acoustically pleasant. Furthermore, the study contributes to discussions on adaptive acoustic comfort in naturally ventilated spaces, providing evidence of how visual perception impacts the acoustic environment. While the research results highlight the positive impact of open windows on the appropriateness ratings of traffic sounds, it is important to consider the limitation of assessing outdoor-recorded traffic sounds at high sound pressure levels (50–65 dBA) without the filtering effect of the facade. This limitation reduces the realism and ecological validity of the experiment, which should be considered when interpreting these results.
