Executive function among adults with autism spectrum disorder: An eye-tracking study.

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by social communication deficits and repetitive behaviors. Eye movement abnormalities are common in ASD, suggesting underlying cognitive impairments such as working memory and response inhibition. However, several investigations suggest deficits in inhibitory control and working memory among individuals with ASD, whereas others indicate performance levels similar to typically developing individuals. The variability observed in executive function (EF) profiles across various tasks and age cohorts underscores the intricate interplay between ASD and cognitive functioning. Therefore, to bridge these gaps and gain a comprehensive understanding of the specific components of EF affected by ASD, this study used eye-tracking technology to analyze cognitive processing. In the working memory task, the clinical group comprised adults with ASD (N = 52), aged between 25 and 47 years (M = 31.65 years, SD = 6.05), while the control group (non-ASD) included individuals (N = 53), aged between 25 and 55 years (M = 33.15 years, SD = 5.92). For the response inhibition task, the clinical group consisted of adults with ASD (N = 50), aged between 25 and 47 years (M = 31.66 years, SD = 6.153), and the control group comprising individuals (N = 56), aged between 25 and 55 years (M = 33.03 years, SD = 5.80). The study revealed that individuals with ASD demonstrate notable impairments and increased errors in EF, encompassing inhibitory control and working memory when compared to non-ASD individuals. Additionally, individuals with ASD exhibited differences in fixation duration, saccade count, and fixation count compared to their non-ASD counterparts, further highlighting the distinct cognitive profile associated with ASD. Analyzing EF in adults with ASD through eye movement patterns provides valuable insights into the underlying cognitive processes and attentional mechanisms at play.

How condensation and non-condensation impact viewers’ processing effort and comprehension – an eye-tracking study on Chinese subtitling of English documentaries

ABSTRACT Interlingual subtitling is expected to be concise to facilitate viewers’ comprehension and avoid drawing their attention, so condensation is a strategy frequently applied. While research has shown that longer subtitles cause longer mean fixation duration, viewers’ processing effort is affected not only by subtitle length but also by linguistic complexity and information intensity. It remains to be investigated whether condensation is suitable for information-intensive genres like documentaries. This study explores viewers’ processing effort for and comprehension of condensed and non-condensed Chinese subtitles of an English documentary via an eye-tracking experiment. Forty-five participants took part in the experiment and did a comprehension test. Data analyses show that the fixation duration per Chinese character for the non-condensed version is significantly lower and the saccade length is significantly larger, implying that the processing effort for non-condensed subtitles is lower. Furthermore, there is no significant difference between the two groups’ comprehension test scores. The results suggest that non-condensed subtitles can be more suitable for information-intensive genres like documentaries.

Multiple factors on driving load in mountain area at night based on factor analysis.

Different driving environments may lead to increased mental workload and fatigue among drivers, consequently diminishing driving safety. To investigate the impact of various factors on drivers' driving load, this study approaches the issue from three perspectives: external weather environment, road driving environment, and in-vehicle driving environment. Through the experimental modeling of the mountainous road section of Provincial Highway S208 in Chongyang County, Xianning City, and employing simulated driving experiments, various factor combinations were designed to investigate the visual characteristics of drivers. Through factor analysis, a comprehensive examination is conducted on four visual indicators: the rate of change in pupil area, fixation duration, saccade velocity, and saccade angle, to explore the patterns of influence exerted by these factors on the driving load of drivers. The evaluation results of driving workload indicate that the degree of driver distraction decreases when the plant spacing is set at 6 meters and the type of road traffic auxiliary facilities is configured to two. When the traffic flow on the road is zero and no driving sub-mission are present, the driver experiences the minimum level of workload. The findings of this study provide robust theoretical support for nighttime mountain driving safety, contributing to the in-depth exploration of traffic safety theories.

The safety of humeroradial fixation using Kirschner wires in children

Humeroradial joint fixation (HJF) has been employed during elbow surgery to maintain stability. Kirschner wire (K-wire) fixation is the most commonly used method in children; however, there are valid concerns regarding complications such as breakage. In this study, we retrospectively analyzed the safety of humeroradial fixation using K-wires in children. In total, 249 patients diagnosed with Monteggia fractures underwent HJF at our institute from January 2013 to November 2021. All relevant clinical data were collected after applying the inclusion and exclusion criteria. Skin irritation, incision infection, elbow instability, and ulnar healing were followed up. The elbow function was evaluated using Mackay standards. There were 81 females and 168 males (average age, 6.6 ± 2.8 years). Of these patients, 67 did not have ulna fixation, whereas 127 were fixed with K-wires after osteotomy of the proximal ulna or correction of the deformity. The K-wire sizes used for HJF were 1.6, 1.8, and 2 mm in 6, 125, and 118 patients, respectively. The duration of K-wire fixation of the humeroradial joint was 6.6 ± 2.5 weeks on average. Two patients suffered from K-wire breakage and underwent reoperation. There were three patients with K-wire end irritation. According to Mackay standards, the elbow function score was excellent, good, and poor in 188, 41, and 20 patients, respectively, at 6 months postoperatively. No bone bridge was found at the capitellum and radial head fixation sites in any patient. HJF using K-wires combined with a cast is a safe method with a low incidence of complications in children and should be considered a reliable option when humeroradial joint fixation is required.Level of evidenceIV.

A novel multi-modal model to assist the diagnosis of autism spectrum disorder using eye-tracking data.

Timely and accurate detection of Autism Spectrum Disorder (ASD) is essential for early intervention and improved patient outcomes. This study aims to harness the power of machine learning (ML) techniques to improve ASD detection by incorporating temporal eye-tracking data. We developed a novel ML model to leverage eye scan paths, sequences of distances of eye movement, and a sequence of fixation durations, enhancing the temporal aspect of the analysis for more effective ASD identification. We utilized a dataset of eye-tracking data without augmentation to train our ML model, which consists of a CNN-GRU-ANN architecture. The model was trained using gaze maps, the sequences of distances between eye fixations, and durations of fixations and saccades. Additionally, we employed a validation dataset to assess the model's performance and compare it with other works. Our ML model demonstrated superior performance in ASD detection compared to the VGG-16 model. By incorporating temporal information from eye-tracking data, our model achieved higher accuracy, precision, and recall. The novel addition of sequence-based features allowed our model to effectively distinguish between ASD and typically developing individuals, achieving an impressive precision value of 93.10% on the validation dataset. This study presents an ML-based approach to ASD detection by utilizing machine learning techniques and incorporating temporal eye-tracking data. Our findings highlight the potential of temporal analysis for improved ASD detection and provide a promising direction for further advancements in the field of eye-tracking-based diagnosis and intervention for neurodevelopmental disorders.

Айтрекинг в нейропсихологическом исследовании особенностей зрительного гнозиса детей с нарушением слуха

<p>The article is devoted to the problem of assessing the state of visual gnosis in children with hearing impairment in order to identify possible mechanisms for compensating for uneven development of mental functions and assessing the possibilities of remedial education. We combined the research potential of the classical neuropsychological approach with the eye-tracking methodology in order to study in detail through eye movements the uneven development of auditory, visual and verbal functions in information processing in children with hearing impairment. The task was to conduct not only a classical neuropsychological assessment of visual gnosis in children with hearing impairment, but also to obtain new data on eye tracking during neuropsychological tests. The study involved cochlearly implanted preschoolers with hearing impairment (N=15) and typically developing preschoolers (N=16) aged 5 to 7 years (M=6.1; SD=0.5). At the first stage, classical neuropsychological tests for visual gnosis were conducted, at the second stage, eye tracking was used to record eye movements during neuropsychological tests by preschoolers. Our study confirms the weakness of visual information processing processes during neuropsychological tests in children with hearing impairment. Analysis of eye movement strategies recorded by the eye tracker during neuropsychological tests allowed us to identify a number of features of visual information processing in children with hearing impairment: chaotic search, changes in the recognition sequence, decreased noticeability (“recognizability”) of images or decreased interest (duration of fixations and viewing), weakness of the holistic strategy and synthesis, fragmentation of perception. The duration of the scanning path, spatial density of fixations, scanning regularity, and scanning direction during image recognition differ. Features of the visual search strategy are observed in the number of switches, fixation time, and patterns of gaze transitions between areas of interest. In children with impairments, when performing tests for visual gnosis, an increase in the time of fixations is recorded, which indicates the cognitive complexity of perception. The combination of weakness in the processing of auditory and visual information leads to diffuseness, incorrectness of the correlation of the image of an object and its verbal designation due to the poverty of the vocabulary of children with hearing impairments.</p>

An Eye Tracker Study on the Understanding of Implicitness in French Elementary School Children

Background: The aim of this study is to use an eye tracker to compare the understanding of three forms of implicitness (i.e., presupposition, conversational implicatures, and irony) in 139 pupils from the first to the fifth year of elementary school. Methods: The child was invited to read short texts composed of a context about some characters and a target sentence conveying one of the three kinds of implicitness. After that, there was a comprehension yes/no question to check whether the child had understood the implicit content of the target sentence. At the same time eye, movements were recorded by a remote system (Pro Fusion by Tobii). The number of correct answers, the duration, and the number of fixations on the texts were measured. Results: We showed that children’s reading time is positively correlated with the accurate comprehension of implicitness, and that children similarly understand the three types of implicitness. Furthermore, the number and the duration of fixations depend both on the age of the children and on their good or poor understanding of the implicit contents. This fact is particularly noticeable for children in the first-grade class, for whom fixations are significantly longer and more frequent when they correctly understand sentences containing implicitness. Conclusion: These results argue in favor of the possibility of teaching the comprehension of some types of implicitness (presupposition, implicature, and irony) from an early age.

Development of an experimental oculographic test battery as part of a software and hardware complex for diagnosing the tendency to computer gaming addiction

Currently, the problem of determining the state of the individual in the «norm-pathology» continuum for non-chemical addictions remains relevant. Our analysis of diagnostic materials allows us to conclude that the vast majority of methods for diagnosing computer gaming addiction are foreign clinical scales translated into Russian, built on the basis of the clinical criteria of the American Psychiatric Association. In connection with this fact, as well as the rapid development of society and the digitalization the practical psychology are needed to modern and effective psychodiagnostic techniques.The research was carried out with the financial support of the Federal State Budgetary Institution «Fund for Assistance to the Development of Small Innovative Enterprises in the Scientific and Technical Sphere» (Innovation Promotion Fund) within the framework of the implementation of innovation project.Purpose of the study - to develop an experimental oculographic test battery for diagnosing computer gaming addiction.Methods. In the empirical research of the first stage of work we used the following methods: clinical conversation; psychodiagnostic methods: method of multilateral personality research by S. Hathaway, J. McKinley (adapted by F.B. Berezina, M.P. Miroshnikova), style of self-regulation of behavior by V.I. Morosanova, questionnaire of volitional self-control by A.G. Zverkova, E.V. Eidman, Distress, Depression, Anxiety and Somatization Questionnaire by B. Terluin (adapted by A.B. Smulevich). To assess oculomotor reactions (fixation duration, number of fixations), we used the GP3 Gazepoint remote software and hardware system for assessing oculomotor reactions.We used the Spearman rank correlation coefficient (p ≤ 0.05) for study the relationships between the structural-dynamic parameters of oculomotor reactions and the personal characteristics of respondents.Results. During the first stage of the work, we obtained the following scientific results: requirements for digital images that make up visual stimuli, and for the visual stimuli themselves have been formulated; stimulus images have been developed to assess the tendency to computer gaming addiction; we was carried out a comparative analysis and studied the relationship between the structural and dynamic parameters of oculomotor reactions and the personal characteristics of respondents; we has been developed the experimental oculographic test battery to diagnose computer gaming addiction.Conclusion. Requirements for visual stimuluses will become part of the guidelines to the oculographic test battery, which will be developed in the second stage of work. Comparative analysis made it possible to identify the most effective visual stimulus that we included in the experimental oculographic test battery.

Saliency response in superior colliculus at the future saccade goal predicts fixation duration during free viewing of dynamic scenes.

Eye movements in daily life occur in rapid succession and often without a predefined goal. Using a free viewing task, we examined how fixation duration prior to a saccade correlates to visual saliency and neuronal activity in the superior colliculus (SC) at the saccade goal. Rhesus monkeys (three male) watched videos of natural, dynamic, scenes while eye movements were tracked and, simultaneously, neurons were recorded in the superficial and intermediate layers of the superior colliculus (SCs and SCi respectively), a midbrain structure closely associated with gaze, attention, and saliency coding. Saccades that were directed into the neuron's receptive field (RF) were extrapolated from the data. To interpret the complex visual input, saliency at the RF location was computed during the pre-saccadic fixation period using a computational saliency model. We analyzed if visual saliency and neural activity at the saccade goal predicted pre-saccadic fixation duration. We report three major findings: 1) Saliency at the saccade goal inversely correlated with fixation duration, with motion and edge information being the strongest predictors. 2) SC visual saliency responses in both SCs and SCi were inversely related to fixation duration. 3) SCs neurons, and not SCi neurons, showed higher activation for two consecutive short fixations, suggestive of concurrent saccade processing during free viewing. These results reveal a close correspondence between visual saliency, SC processing, and the timing of saccade initiation during free viewing and are discussed in relation to their implication for understanding saccade initiation during real-world gaze behavior.Significance statement Contrary to traditional controlled stimuli/task studies, eye movements in day-to-day life are not discrete events but occur in (rapid) succession and often without a predefined goal. Therefore, the study of visual processing during free viewing of dynamic scenes is an essential step in understanding visual processing in its functional context. We present an investigation into saliency and visual responses in the superior colliculus (SC) during task-free viewing of dynamic videos and their correspondence to saccade initiation. In short, these results show the correspondence between fixation duration, pre-saccadic visual saliency at the saccade goal and SC processing and provide first evidence of a neural correlate of concurrent visual processing across a chain of saccades in the SC during free viewing.

Eye movements of children with and without developmental dyslexia in an alphabetic script during alphabetic and logographic tasks

Eye movements (EM) during naming alphabetic versus logographic stimuli in children with and without developmental dyslexia (DD) were examined for each stimulus separately to identify conspicuous characteristics that influence naming performance. 40 children (group DD = 18; control group C = 22) were taught Chinese characters. EM were recorded during naming alphabetic words, pictures and Chinese characters. Main variables were articulation latencies, numbers and durations of fixations, secondary variables were fixation locations and error rates. Group DD showed significantly longer latencies and more fixations while reading words, but only insignificantly more fixations while naming pictures and Chinese characters. However, their error rate was significantly higher during naming Chinese characters but correlated neither with severity of phonological deficit nor with visual complexity. Their first fixation was significantly more often on the center of characters, in group C on the left. In both groups, EM variables were influenced by conspicuous features of characters, such as visual complexity, composition and structure. EM variables and scanning behavior while naming Chinese characters indicate holistic processing in the visuo-spatial pathway and were affected by conspicuous features of characters. The higher error rate in group DD could be determined by several factors, without a major role of the phonological deficit.

Identification of Distinct Visual Scan Paths for Pathologists in Rare-Element Search Tasks.

The search for rare elements, like mitotic figures, is crucial in pathology. Combining digital pathology with eye-tracking technology allows for the detailed study of how pathologists complete these important tasks. To determine if pathologists have distinct search characteristics in domain- and nondomain-specific tasks. Six pathologists and six graduate students were recruited as observers. Each observer was given five digital "Where's Waldo?" puzzles and asked to search for the Waldo character as a nondomain-specific task. Each pathologist was then given five images of a breast digital pathology slide to search for a single mitotic figure as a domain-specific task. The observers' eye gaze data were collected. Pathologists' median fixation duration was 244 ms, compared to 300 ms for nonpathologists searching for Waldo (P < .001), and compared to 233 ms for pathologists searching for mitotic figures (P = .003). Pathologists' median fixation and saccade rates were 3.17/second and 2.77/second, respectively, compared to 2.61/second and 2.47/second for nonpathologists searching for Waldo (P < .001), and compared to 3.34/second and 3.09/second for pathologists searching for mitotic figures (P = .222 and P = .187, respectively). There was no significant difference between the two cohorts in their accuracy in identifying the target of their search. When searching for rare elements during a nondomain-specific search task, pathologists' search characteristics were fundamentally different compared to nonpathologists, indicating pathologists can rapidly classify the objects of their fixations without compromising accuracy. Further, pathologists' search characteristics were fundamentally different between a domain-specific and nondomain-specific rare-element search task.

Effectiveness of negative pressure wound therapy in complex surgical treatment of necrotizing fasciitis of the upper limb.

Necrotizing fasciitis (NF) of the upper extremities is a severe surgical pathology, and the incidence of this disease has been steadily increasing in recent decades. Surgical treatment is accompanied by the formation of extensive wounds, which can be treated with significant difficulties. In recent years, negative pressure wound therapy (NPWT) has proven to be highly effective. It is also promising for the treatment of NF. To explore the effectiveness of NPWT in the treatment of NF of the upper extremities. The results of the treatment of 36 patients with NF of the upper extremities in two groups (NPWT group and control group; 2022-2023) were retrospectively analyzed. In the NPWT group, the NPWT method (120 mmHg; constant mode) was used after surgical treatment. The number of vacuum-assisted dressings in patients ranged from 1 to 3, depending on the dynamics of the wound process. The duration of fixation of one bandage was up to 2-3 d. In the control group, conventional methods of local wound treatment were used. The following indicators were analyzed: The treatment delay, the prevalence of inflammation, the microbial landscape, the number of debridements, the duration of wound preparation for surgical closure, and the nature of skin plastic surgery. Most patients experienced a significant treatment delay [4 d, interquartile range (IQR): 2-7 d], which led to the spread of the pathological process to the forearm and shoulder. The most common pathogens were Staphylococcus aureus (14; 38.9%) and Streptococcus pyogenes (22; 61.1%). The average number of debridements per patient was 5 (IQR: 3-7), with no difference between groups. The average time to prepare wounds for surgical closure was 11 ± 4 d in the NPWT group and 29 ± 10 d (P = 0.00001) in the control group. In the NPWT group, the wounds were more often closed with local tissues (15; 83.3%), and in the control group, split-thickness skin grafts were more often used (4; 50%). The predominant isolation of Staphylococcus aureus and/or Streptococcus pyogenes from the lesions allowed us to classify these patients as NF type II. Multiple debridement procedures have become a feature of this disease treatment. The use of NPWT has significantly reduced the time required to prepare wounds for surgical closure. Early closure of wounds allows for more frequent use of local tissue repair, which ensures better results. NPWT is a highly effective way to prepare wounds for early surgical closure in patients with upper extremity NF.

Eye movements in binary food choice context: assessing the complexity of restaurant menus on virtue vs. vice foods

ABSTRACT This paper explores binary food choices through the lens of information load theory. We conducted two laboratory studies using the eye-tracking approach to understand the influence of the high menu complexity on visual attention for virtue versus vice food options. This paper also examined the moderating effect of time on the initial fixation. Our findings showed that the time duration taken to reach the first fixation influences binary food choices. This was evident when participants were tasked with selecting food options from a high menu complexity. Specifically, fixation duration is greater for virtue food than vice food in a high menu complexity context. However, no differences in fixation duration between vice and virtue foods were observed in low menu complexity. This study provides key insights into understanding how differences in menu complexity impact customers’ binary food choice decisions concerning vice and virtue foods.

Reading comics: The effect of expertise on eye movements

The theory of expertise suggests that there should be observable differences in the eye movement patterns between experts and non-experts. Previous studies have investigated how expertise influences eye movement patterns during cognitive tasks like reading. However, the impact of expertise on eye movements in comics, a multimodal form of text, remains unexplored. This article reports on a study that uses eye tracking to examine patterns in the ways that experts and non-experts read comics. Expert participants (14) with experience in reading comics than non-expert participants (17). When controlling for variables such as layout and text quantity, we found significant differences in visual scanning between experts and non-experts. Experts exhibited more frequent saccades and greater amplitude of saccades. Further analysis revealed distinct strategies in processing text and image content between the two groups: the interaction between expertise level and content type in specific AOI showed significant differences across multiple visual measurement metrics, including Average duration of fixations, number of fixations, and number of saccades within AOI. These findings not only support the applicability of the expertise level theory in the field of comic reading but also provide a new perspective for understanding the reading processing of multimodal texts.

Fixation durations on familiar items are longer due to attenuation of exploration

Previous studies have shown that fixations on familiar stimuli tend to be longer than on unfamiliar stimuli, theorized to be a result of retrieval of information from memory. We hypothesize that extended fixations are due to a lesser need to explore an already familiar stimulus. Participant's gaze was tracked as they tried to encode or retrieve a familiar face displayed either alone or alongside other unfamiliar faces. Regardless of the memory task (encoding\\retrieval), longer fixation durations were observed when a single familiar face was presented alone, and not when presented among unfamiliar ones. Thus, fixations were not prolonged when it was possible to explore other, unfamiliar stimuli. We conclude that prolonged fixations on familiar stimuli reflect a lesser need to explore an already familiar percept. The results underscore how memory representations influence active sensing, yielding fresh insights into efficient deployment of attention resources. We conclude that fixation durations could be used in applied memory detection tests, preferably together with other measures and when the familiar stimulus is presented alone.

Effects of sequential and non-sequential presentation conditions of multiple-stem facts on memory integration and cognitive resource allocation.

What limits the self-generation of new knowledge in the memory integration process? One striking contender is the amount of necessary pieces of information that are dispersed. Specifically, when essential information is scattered across multiple sources/places, it becomes challenging to effectively integrate and generate new knowledge. Most of the studies on memory integration have focused on the study of paired stem facts, but have neglected the exploration of multiple-stem facts. The present study examined college students' performance on memory integration under different conditions of three stem facts. In Experiment 1, participants were exposed to a series of novel, authentic stem facts in which every three relevant ones could be integrated to generate new knowledge. The results of Experiment 1 found that college students could spontaneously generate a new piece of information by integrating two or three separate but related facts. The integration can occur in at least two distinct types due to the different presentation orders of the learning materials: sequential recursive integration and non-recursive integration. College students performed better in sequential recursive integration than in non-sequential recursive integration, and this difference in integration performance is not caused by differences in memory for the stem facts. Based on Experiment 1, Experiment 2 used eye-tracking technology to explore the allocation of internal cognitive resources across different conditions of three stem facts. We found that in non-sequential recursive integration, college students had the longest visual duration and the highest number of fixations on the second stem fact. In sequential recursive integration, there were no other significant differences in the number and duration of visual fixations for the three stem facts. College students paid longer fixations to the second stem fact and the third stem fact in the non-sequential recursive condition than in the sequential recursive condition. Our study suggests that when information is related but cannot be integrated, longer fixation indicates stumbling when dealing with an unresolvable difficulty. When knowledge is presented in a stepwise manner (such as in the sequential recursive integration condition), it results in better semantic memory extension.

The effects of embedded quizzes on self‐regulated processes and learning performance during a multimedia lesson

AbstractBackgroundPrevious research has demonstrated that quizzing can improve self‐regulation processes and learning performances. However, it remains unclear whether quizzes in multimedia material bring similar benefits, and whether interindividual differences such as working memory capacity (WMC) modulate quizzing effects.AimsThis study aimed to examine the effects of embedded quizzes (multiple quizzes within the learning sequence) with feedback during a multimedia learning sequence on self‐regulated processing (monitoring and control) and learning performances on repeated (material already tested) and new (untested) questions, and possible WMC moderation on performances.Sample and MethodsParticipants were 59 students who learned a multimedia neuroscience course module in either a no‐quiz or embedded quizzes condition. With regard to self‐regulated processing, control was assessed with eye‐tracking measures (fixation durations and transitions between texts and illustrations), and monitoring by comparing self‐reported judgements of learning with actual performances (calibration). At the end, students' WMC was measured, and learning performances were assessed with repeated and new questions.ResultsQuizzing improved learning performances on repeated and new questions, and enhanced monitoring (better calibration). Students with low WMC benefited more from quizzing for new questions than those with high WMC. However, contrary to our hypothesis, the embedded quizzes group allocated less time to the learning than the no‐quiz group.ConclusionsEmbedded quizzes are relevant tools to help students recalibrate their monitoring process and foster more effective self‐regulated learning. Results confirm that the use of quizzes can be recommended to improve the learning of multimedia material, especially among students with low WMC.

A study on color visual perception of museum exhibition space based on eye movement experiments.

Color is an essential element in the exhibition space of museums, influencing people's visual experience. To quantitatively study the relationship between color and individual visual perception in museum exhibition spaces, the study used eye-tracking technology combined with a questionnaire, exploring the relationship between color and visual perception in the exhibition environments of history museums in terms of hue, saturation, and brightness of color. Taking the Ruijin Central Revolutionary Base in Jiangxi Province as a historical display space for research, the results show that when the saturation is 69-77%, or the hue is red (0°H), the exhibited. environments have stronger color attractiveness. The study demonstrated that the first fixation duration in eye movement data significantly negatively correlates with the subject's personal preference, comfort, pleasure, and attractiveness. Researchers can use this as an evaluation parameter for visual perception of exhibition space.

How does contextual information affect aesthetic appreciation and gaze behavior in figurative and abstract artwork?

Numerous studies have investigated how providing contextual information with artwork influences gaze behavior, yet the evidence that contextually triggered changes in oculomotor behavior when exploring artworks may be linked to changes in aesthetic experience remains mixed. The aim of this study was to investigate how three levels of contextual information influenced people's aesthetic appreciation and visual exploration of both abstract and figurative art. Participants were presented with an artwork and one of three contextual information levels: a title, title plus information on the aesthetic design of the piece, or title plus information about the semantic meaning of the piece. We measured participants liking, interest and understanding of artworks and recorded exploration duration, fixation count and fixation duration on regions of interest for each piece. Contextual information produced greater aesthetic appreciation and more visual exploration in abstract artworks. In contrast, figurative artworks were highly dependent on liking preferences and less affected by contextual information. Our results suggest that the effect of contextual information on aesthetic ratings arises from an elaboration effect, such that the viewer aesthetic experience is enhanced by additional information, but only when the meaning of an artwork is not obvious.

"Mirror, mirror in the call": Exploring the Ambivalent Nature of the Self-view in Video Meeting Systems with Self-Reported &amp; Eye-Tracking Data

Video meeting systems offer great potential for work and life, but they can also have negative effects. One reason is the presence of technical stimuli that do not exist in the physical world. A prominent example is the self-view feature, a mirrored image of oneself shown during the video meeting. The self-view feature comes with a trade-off between the advantage of enhancing control and the disadvantage of increasing cognitive load of its users. So far, research is scarce when it comes to understanding this ambivalent nature and studies mostly relied on self-reported data without considering the actual interaction with the self-view. To address this gap, we conducted an experimental study with 57 participants and two design variants (with/without self-view), analyzed user perceptions through surveys and interviews, and explored gaze patterns using eye-tracking technology. Results reveal varying perceptions of cognitive load and control among self-view users and between the design variants, highlighting its ambivalent nature. We see differences in how participants interact with the self-view. In a cluster analysis, we identify three user groups (Benefiting Users, Cognitively Challenged Users, Control Losing Users). These groups also show differences in visual behavior, especially median fixation duration, and user characteristics. Based on our findings, we outline design recommendations for more flexible and intelligent design solutions by considering user groups and their individual differences.
