Уровни понимания и градуальность смысловой организации текста: комплексный подход на стыке психологии и лингвистики

<p>The article describes an interdisciplinary framework which we have developed to study verbal text comprehension based on a combination of psychological and linguistic approaches. The comprehension phenomenon is considered to be a result of a reversible transformation between verbal symbols and mental images of the to-be-comprehended material, with the obligatory condition of preserving its semantic invariance. We emphasize a gradual nature of comprehension and its reliance on a coordinated activity of the recipient's cognitive and emotional mechanisms. We pay particular attention to the negative potential of subjective projections in the comprehension process. We also describe the method of in-depth semi-structured interview, which allows for a multi-level explication of the processes involved in building up a mental representation of the text’s content. As a model for studying the comprehension phenomenon, we suggest a short story "Invisible Japanese Gentlemen" by G. Greene, which has a complex intrinsic structure of implicit meanings. Using linguostylistic and propositional analyses, we described the story’s structure of implicit meanings and identified its various elements (87 in total) and 66 key textual propositions. The reliability analysis showed a high degree of consistency between the experts' (ɑ = 0.6 for elements, ɑ = 0.67 for propositions). This indicates that this text and the structure of its implicit meanings can serve as an adequate stimulus material for studying the comprehension phenomenon. Finally, based on in-depth semi-structured interview data (N = 30), we developed a set of quantitative criteria for assessing the completeness of text comprehension on a 5-point scale.</p>

Evaluative Perception of Memes Among Youth Internet Audiences: A Pilot Psycholinguistic Experiment

This study explores the evaluative perception of memes and demotivators among youth internet audiences within the framework of a pilot psycholinguistic experiment. The research identifies the specifics of evaluative opinions, verbal reactions, and the components of multimodal texts that effectively capture attention. Data collection was conducted using the online service Yandex Forms, with a sample of 100 participants aged 18 to 22 years. The stimulus materials comprised a heterogeneous set of multimodal texts, including 26 memes and demotivators featuring static images. The results and statistical analyses reveal the ambiguity in evaluative perceptions and the breadth of preferences among participants. Analysis of evaluative opinions indicates a strong preference among youth audiences for humorous, contemporary, and original multimodal texts that accurately reflect life realities, including those related to their social status. Conversely, outdated and irrelevant memes, both in form and content, elicited negative reactions, being perceived as unfunny and foolish, and contrary to their viewpoints. The study also highlights distinctive features in the evaluative perception and interpretation of meme content elements by participants, including variability in interest distribution, polarization of opinions regarding the same content element, and the influence of individual preferences and personal experiences.

Motion Cognitive Decoding of Cross-Subject Motor Imagery Guided on Different Visual Stimulus Materials.

Motor imagery (MI) plays an important role in brain-computer interfaces, especially in evoking event-related desynchronization and synchronization (ERD/S) rhythms in electroencephalogram (EEG) signals. However, the procedure for performing a MI task for a single subject is subjective, making it difficult to determine the actual situation of an individual's MI task and resulting in significant individual EEG response variations during motion cognitive decoding. To explore this issue, we designed three visual stimuli (arrow, human, and robot), each of which was used to present three MI tasks (left arm, right arm, and feet), and evaluated differences in brain response in terms of ERD/S rhythms. To compare subject-specific variations of different visual stimuli, a novel cross-subject MI-EEG classification method was proposed for the three visual stimuli. The proposed method employed a covariance matrix centroid alignment for preprocessing of EEG samples, followed by a model agnostic meta-learning method for cross-subject MI-EEG classification. The experimental results showed that robot stimulus materials were better than arrow or human stimulus materials, with an optimal cross-subject motion cognitive decoding accuracy of 79.04%. Moreover, the proposed method produced robust classification of cross-subject MI-EEG signal decoding, showing superior results to conventional methods on collected EEG signals.

Понимание подростками электронного учебного гипертекста (в сравнении с печатным гипертекстом)

<p>The article presents the results of a study comparing reading and understanding of two identical versions of educational hypertext – electronic and printed. The relevance of the work is determined by the important role of hypertext structures in the system of modern digital technologies, the need to teach schoolchildren effective strategies for navigation, search and analysis of hypertext information. The study involved 108 students in grades 7-8 of secondary schools in Moscow and the Moscow region. A specially designed educational hypertext of humanitarian content was used as a stimulus material. A comparative analysis of electronic and printed hypertext was carried out according to the following parameters: understanding of the general content of the text, understanding of conceptual and factual information. It was found that students who worked with electronic hypertext coped with the diagnostic test in general and with understanding factual information in particular significantly better (p <0.05) than those who worked with the paper version. Conceptual information understanding was also more successful when reading from the screen, although the differences were insignificant (p>0.05). However, regardless of the reading format, most students demonstrated superficial comprehension: only 9.7% of them were able to fully correctly understand and formulate the main idea of ​​the text, and about half (50.5%) failed to complete the task. The data obtained allow us to conclude that, although working with hypertext is more successful in a digital environment, the prevalence of incomplete and inaccurate understanding indicates the need for special regular work in schools to teach students effective strategies for interacting with hypertext both from screens and from paper.</p>

Social Perception of Male Faces. Individuals, Clusters, Dimensions

In an online experiment in a German and an English version, portrait photographs of 59 men from the age range late 20s to late 50s served as stimulus material. 1618 participants each rated a randomly selected photo on 36 personality-descriptive rating scales and estimated the age, body height and weight. In supplementary assessments, the degree of smile, degree of hair loss, hair color, facial hair, glasses, formal dress, head rotation, head tilt and brightness of the image background were determined. All variables show sufficient, mostly high to very high reliability. The data analysis was carried out at the level of the stimulus persons, on the one hand from a dimensional and on the other hand from a typological perspective. A principal component analysis of the personality-descriptive traits yielded a five-dimensional space with orthogonal factors. These can be interpreted straightforwardly as Social Agreeableness, Attractiveness, Masculinity, Status/Intelligence and Negative Affects. Using multiple regression, the age estimates and the degree of smiling can be fitted into the psychological space in an excellent way. Wearing glasses and height estimates can also be localized well in this space. In addition to the customary dimensional approach, a typological approach was adopted, which is rarely found in this field of research. In a hierarchical cluster analysis of the five personality dimensions and the external characteristics, groups of stimulus persons were identified who are similar to each other in a bundle of characteristics and who differ markedly from other groups. These clusters were mapped into the five-dimensional face perception space. In this way, it is demonstrated that not only does each approach provide interesting insights in its own right, but that both approaches mutually enrich each other by combining them. A main emphasis of this paper is the comparison with the two-dimensional Valence-Dominance model, which has been the most influential paradigm for more than a decade. It is not disputed that evaluation on the Badness – Goodness dimension is of paramount importance, nor is the importance of Dominance or Power called into question. Nevertheless, it is shown that a two-dimensional model cannot do justice to the complexity of face perception. Face perception is much more differentiated and – this is the crucial point – it largely coincides with the personality structure known from differential psychology, which is based on self-assessments and assessments of acquaintances.

Восприятие пиктографических систем альтернативной коммуникации при расстройствах интеллектуального развития

<p>Alternative communication is an assistive communication tool for people with communication disorders. Because of the variety of alternative communication symbols' graphic representation, it is important to evaluate both classical and unstudied symbolic systems from the perspective of their effectiveness in compensating communication difficulties for persons with disorder of intellectual development. This article deals with the specifics of visual perception and interpretation of concept-nouns and concept-verbs as elements of pictographic alternative communication. The sample of the study (N=92) consists of high school students at special education schools aged 13 to 19 years (M=15.5; SD=1.18), 72% are male. The study's stimulus material was composed of pictogram interpretation tasks in a verbal context and included symbols from three alternative communication languages: Blissymbolics, LoCoS ©, and Pictogram. The analysis of associative interpretations has shown that the factor of pictogram belonging to the particular system affects the correct interpretations of students with mild disorder of intellectual development (p=0.008), as well as the parameters of eye-movement activity: the number of gazes returns to pictograms (p=0.007), number of fixations (p=0.018) and viewing time (p=0.037). We conclude that, considering the cognitive characteristics of students with mild disorder of intellectual development, simpler graphic forms have the greatest efficiency in conveying information, regardless of the part of speech or level of schematism.</p>

A Registered Conceptual Replication and Extension of Carter and Weber (2010): Generalized Trust, Lie Prevalence, and Deception Detection

This paper provides a conceptual replication and extension of Carter and Weber investigating the effects of generalized trust on deception detection. Three alternative predictions were tested: trust lowers accuracy, trust increases accuracy, or trust facilitates accuracy for truths but inhibits lie detection. Compared to Carter and Weber, our experiment involved different stimulus materials, a much larger sample, and the inclusion of a lie prevalence measure. As anticipated, Carter and Weber’s finding were not replicated. Neither generalized trust nor lie prevalence predicted deception detection accuracy or truth bias. We speculate about why generalized trust appears to play little role in deception detection.

The Effects of Virtual Reality-Based Reminiscence Therapies for Older Adults With Cognitive Impairment: Systematic Review.

Reminiscence therapy (RT) is a commonly used nonpharmaceutical treatment for cognitive impairment. Artifacts or conversations are used in RT to recall individuals' memories and past experiences. Virtual reality (VR) has increasingly been used as an assistive technology during RT. However, the effects of VR-based RT (VR-RT) methods remain unclear, and insights into the related benefits and challenges are urgently needed. The study aims to systematically review the effects of VR-RTs for older adults with cognitive impairment. Seven databases (MEDLINE, Academic Search Premier, CINAHL, Web of Science, PubMed, the Cochrane Central Register of Controlled Trials, and ScienceDirect) were searched to identify relevant articles published from inception to August 10, 2023. Peer-reviewed publications that assessed the effect of VR-RTs (ie, using virtual clues to evoke participants' memories or past experiences) on cognitive-related outcomes were included. Two independent researchers conducted the literature search, review, and data extraction processes. A narrative synthesis approach was used to analyze the extracted data. Of the 537 identified articles, 22 were ultimately included in the data analysis. The results revealed that VR-RTs could maintain cognitive status (4/4, 100%) and reduce anxiety (2/2, 100%) in older adults with cognitive impairment. Nevertheless, one study found a cognitive improvement after VR-RTs, whereas cognitive degradation was observed at a 3- to 6-month follow-up measure. Around 88% (7/8) of the included studies indicated that VR-RTs improved memory; however, the evidence regarding the beneficial effects of VR-RTs was limited in improving quality of life (1/4, 25%) and reducing apathy (0/2, 0%) and depression (1/3, 33%). The results indicated that VR-RTs are safe, engaging, acceptable, and satisfying for older adults with cognitive impairment. In VR scenarios, personalized stimulus materials related to the users' youth experiences were more effective for treating cognitive impairment than other stimulus materials. The results of this systematic review demonstrate the potential benefits of VR-RT for older adults with cognitive impairment, especially in improving emotion and memory and maintaining cognitive status. VR-RT is also safe and enjoyable for older adults. However, due to the trial heterogeneity of included studies, we can only provide qualitative results instead of performing meta-analysis to quantify the effect size of VR-RTs. Thus, more randomized controlled trials are required to examine the designs and effects of VR-RTs for groups of older adults with specific needs.

Modulation of memory by prism adaptation in healthy subjects

Recent findings suggest that prism adaptation can extend its effects beyond spatial attention, modulating the performance of different cognitive tasks by acting on cerebellar, parietal and temporal-frontal networks. We tested groups of healthy subjects to investigate the effects of rightward vs. leftward prism adaptation vs. neutral lenses exposure in a series of memory tasks, probing either short-term (Digit span, Corsi span) or long-term memory (Supraspan verbal and spatial learning). In the short-term memory tasks, leftward prism adaptation selectively increased verbal span, while rightward prism adaptation increased spatial span. In the long-term memory tasks, leftward prism adaptation selectively increased verbal supraspan, i.e., increased the number of digits in the correct sequence reproduced and reduced the number of repetitions needed to learn the supraspan sequence. On the other hand, rightward prism adaptation selectively increased spatial supraspan, i.e. it increased the number of spatial positions in the correct sequence reproduced and reduced the number of repetitions needed to learn the supraspan sequence. Moreover, rightward, but not leftward, prism adaptation selectively increased supraspan recall after a delay interval, regardless of the stimulus material, i.e., it increased the number of digits or spatial positions recalled after a delay interval. Neutral lenses exposure did not influence any memory task. These findings suggest that prism adaptation can induce both modality/hemispheric-specific and process-specific effects on short-term and long-term explicit memory.

Modifying the Methodology of Letter Cancellation Test for Digital Representation

Standard tools of attention diagnosis have seen only a few attempts of modernization. A theoretical and methodological analysis revealed data contradictions both in assignment and criteria. Digital versions of cognitive diagnostic material could be more objective due to modern hardware and software methods that register psychophysiological indicators. This research was an attempt to digitalize a standard letter variant of letter cancellation test. It involved a theoretical and methodological analysis of attention studies and diagnostic methods. The authors developed new stimulus material for digital attention tests and studied them using oculography. The research involved 90 people (33 men and 57 women) aged 16–70 y.o. The oculography revealed a set of oculomotor reactions that made it possible to describe the peculiarities of attention process and its stages, as well as to establish such a phenomenon as inattention blindness. The experiment also revealed some stable patterns in search strategies and oculomotor reactions that occurred during the testing. While searching for a target stimulus in a limited time, respondents usually employ two basic strategies: 1) they read elementary units of information to integrate them into a single image; 2) they stick to symbolic content with subsequent selective processing to select the target stimulus from the information flow. In this research, however, the participants also used additional strategies: 3) they completely ignored the target word; 4) they reduced the volume of the target stimulus (incomplete response) with its complete detection by oculomotor reactions; 5) they combined elements mechanically; 6) they turned to confabulation.

Effects of scenery frame on visual depth perception in classical Chinese gardens: A case study of the Lvyin Pavilion in Lingering Garden

Visual depth (distance) perception is a fundamental aspect of environmental cognition, as it allows people to judge the spatial scale of their surroundings. However, estimating the depth of classical Chinese gardens is challenging, especially from static viewpoints that frame the scenery. Previous studies have examined how the internal components of the scenery frame affect depth perception. Still, the role of the frame and its peripheral information as environmental background have been largely overlooked. This study investigates how depth perception at viewpoints is influenced by viewing position displacement, frame geometry, and environmental context. The authors created nine stimulus materials in a cave virtual reality environment (three image treatments × three positions). Seventy-one participants were asked to evaluate depth perception using the magnitude estimation and adjustment methods. Their eye movement behavior was also recorded using an eye-movement instrument (SensoMotoric Instruments (SMI) eye-tracking glasses, 120 Hz). The results showed that participants could perceive spatial depth differences between viewing positions even when the internal viewpoint displacement was small; frame shape did not significantly affect depth perception and gaze behavior; and peripheral visual information of the frame enhanced depth perception significantly. Moreover, the form of the environmental background, especially the position of the scenery window, strongly guided the participants’ gaze. These findings suggest that ambient visual information significantly impacts environmental experience, which landscape designers should consider.

A Computer Vision System for an Automated Scoring of a Hand-drawn Geometric Figure

Visual Reproduction is a condition to measure Visual Spatial Memory as one of the cognitive domains commonly used to measure visuo-spatial memory. Geometric figures serve as stimulus material, and probands have to reproduce the figures from memory through a hand drawing. The scoring of the drawing has subjective elements. This study aims to evaluate the scoring criteria for the Figural Reproduction Test (FRT), part of the Indonesian Neuropsychological Test Battery, and to develop and evaluate an automated scoring system based on computer vision technology (FRT-CVAS). Scoring evaluation conducted by Cohen Kappa analysis, accuracy, sensitivity, and specificity. The analyzes of the three criteria of the manual confirmed a subjective element in the scoring of the shape of triangles by a moderate (0.74) inter-rater agreement; this agreement could be improved to 0.84 by a slight modification of its criteria. FRT-CVAS, based on computer vision’s identification of the different elements of the hand drawing, was developed and trained using 290 drawings. The system was additionally tested by comparing its scoring with the scoring of two independent raters on 120 drawings from a second data set. FRT-CVAS recognized all elements, and its comparison between human raters showed a high accuracy and sensitivity (minimally 0.91), while the specificity was 0.80 for one of the three criteria. FRT-CVAS offers a highly standardized, consistent, precise, and objective output from the first card in the FRT. This approach is advantageous to data-hungry alternatives such as deep learning when applied to the automated scoring of hand drawings with relatively little data available for training.

Multifunctional Microneedle Patch with Diphlorethohydroxycarmalol for Potential Wound Dressing.

Treatment of skin wounds with diverse pathological characteristics presents significant challenges due to the limited specific and efficacy of current wound healing approaches. Microneedle (MN) patches incorporating bioactive and stimulus materials have emerged as a promising strategy to overcome these limitations and integrating bioactive materials with anti-bacterial and anti-inflammatory properties for advanced wound dressing. We isolated diphlorethohydroxycarmalol (DPHC) from Ishige okamurae and assessed its anti-inflammatory and anti-bacterial effects on macrophages and its antibacterial activity against Cutibacterium acnes. Subsequently, we fabricated polylactic acid (PLA) MN patches containing DPHC at various concentrations (0-0.3%) (PDPHC MN patches) and evaluated their mechanical properties and biological effects using in vitro and in vivo models. Our findings demonstrated that DPHC effectively inhibited nitric oxide production in macrophages and exhibited rapid bactericidal activity against C. acnes. The PDPHC MN patches displayed potent antibacterial effects without cytotoxicity. Moreover, in 2,4-Dinitrochlorobenzene-stimulated mouse model, the PDPHC MN patches significantly suppressed inflammatory response and cutaneous lichenification. The results suggest that the PDPHC MN patches holds promise as a multifunctional wound dressing for skin tissue engineering, offering antibacterial properties and anti-inflammatory properties to promote wound healing process.

The game as a methodological means of training students of humanities at the university

The article is written in the context of an integrative approach to psychology that combines methods for studying personality and group from different areas of human knowledge, contributing to the creation of a comprehensive psychosocial methodological apparatus aimed at studying the process of providing social and psychological support and assistance in an individual and group format. The article reveals the essence of a psychological game as a resource that contributes to the formation and development of professionally significant personal qualities and skills of university students majoring in the humanities (psychology students). In the course of the study, we proved the possibility of developing empathy in students with the help of psychological game practices in the educational environment of the university. Conceptualization of the definitions of the phenomena of the emotional sphere of personality functioning in bachelors of the 1st and 2nd years of study was carried out. The effectiveness of the development of game materials was assessed: bingo sheets and emotionally rich dialogues, as a stimulus material for recognizing emotions. A methodological justification for the effective use of gamification technologies in the educational process at the university is given. As a result of the empirical study, the training focus of the developed game «Empati-Bingo» was determined, prospects for improving the stimulus material, the possibilities of diagnosing the level of empathy development in students using game tools were determined. It was revealed that the psychological game «Empati-Bingo» requires a high level of empathy development in its leaders. The accuracy of recognition and determination of emotion can reflect the level of development of the cognitive component of empathy as a component of emotional intelligence. To improve the internal validity of the psychological game, the range of emotions that were proposed to be defined was expanded for the declared constructs of emotion and emotional intelligence: dialogues containing negative emotions were added, some emotionally neutral situations arising in interpersonal interaction were removed, which made the stimulus material more understandable for the game participants.

A question of perspective: Perspective as a feature in stimulus-response binding

ABSTRACT In action control research, stimulus-response binding and retrieval processes are assumed core mechanisms. Stimulus and response features are integrated into event files when they occur together. This event file is retrieved if any feature is repeated. Partial mismatches between current and retrieved episodes cause conflicts, leading to performance costs, while full matches improve performance (the difference between these conditions is known as binding effects). Such binding effects have been found for different stimulus features like colour, shape, or location, using stimulus material that is often kept very simple. In our study, we manipulated the perspective on a real-world three-dimensional distractor stimulus. We found that perspective was bound to the response, independent of stimulus identity. It seems that perspective is treated as a stimulus feature in action control. This result enhances the way we discuss what a feature actually is and how features are bound in event files.

The Impact of Using Doodling in The Educational Environment On the Degree of Learning of Educational Material

Introduction. This article is devoted to the study of doodling as a process of unconscious drawing by students during active thinking activity under experimental conditions. The relevance of the study is conditioned by the expressed public demand for the development and implementation of new methods and technologies in the modern educational process. The novelty of the study lies in the relatively low level of study of this phenomenon to date and the contradictory nature of the available practical data on its effectiveness. Thus, the presented work will help to supplement the still unstable scientific understanding of such a widespread phenomenon as “drawing on the margins”. Objective. To compare the degree of learning of educational material in students when using doodling and the classical method of memorization on the basis of historical text. Materials and Methods. Forty-eight psychology students at SFU, aged 17 to 22 years, 43 of them women and 5 men, were chosen as subjects. The subjects were divided into control and experimental groups, each of which was read a historical text. Then, 30‒40 minutes after the end of the experiment, each group completed the author’s questionnaire of 10 open-ended questions on the listened material. The results of each subject were evaluated by the degree of the completeness of answers and summarized for each group to then find the average value for each and compare. Results. The experimental group, which used doodling techniques, showed noticeably worse learning and reproduction results than the control group. Discussion. The results obtained are partially reflected in the work of other authors who were unable to reproduce the data, showing the advantages of doodling in memorizing information. It can be assumed that the results of the experiment were influenced by the relatively small size of the stimulus material and the morning time of the experiment: the subjects did not have time to tire, so they did not have a natural need for additional methods of attention retention. Perhaps, for this reason, a natural experiment could show better results on the use of doodling than a laboratory experiment. It is alsopossible that this method is only useful for people with certain characteristics. Further experimental studies with other conditions of doodling playback in different educational environments, subjects, and stimulus material are needed to clarify the phenomenon.

Theoretical and Empirical Justifications for The Development of the Questionnaire “Subjective Evaluation of Lukism in Humor”

Introduction. The paper deals with the problem of lookism (discrimination based on appearance) on the example of evaluating humorous posts and memes, which in various social situations can act as triggers of lookism. In order to diagnose sensitivity to Lukism in jokes, we attempted to prepare a basic description of the future structure of the methodology by testing a number of statements obtained by other authors in relation to different types of jokes. The novelty of the study lies in the description of the stages of preparation of the stimulus material, which allows us to study the peculiarities of perception of humor that ridicules the features of appearance and sensitivity to such jokes depending on the respondent’s experience (as a victim or a witness). Objective. To test a number of assumptions that are essential for the development of a questionnaire to examine the subjective evaluation of Lukism in humor. Materials and Methods. The study was conducted in five stages, a total of 410 participants (54 men, 356 women), aged 19 to 46 years, each stage included consideration of different components of perception and evaluation of humor in terms of the perception of it as offensive/containing lukism. Results. At each stage the peculiarities of perception of humorous posts that are distributed in social networks were revealed. It was revealed that the way of design (textual, textual-visual, as well as peculiarities of using different visual components), as well as the personal experience of respondents who faced situations of Lukism and self-assessment of respondents’ appearance influence the perception of a joke as containing or not containing Lukism, as well as the prediction of its assessment by other people as “offensive”. Discussion. Considering memes as complex, multilevel texts of identity, we see in them a significant potential for studying social norms, stereotypes and attitudes about appearance and sensitivity to the assessment of it as “non-standard” and a target for jokes. At the empirical level, we have identified a number of requirements for the selection of jokes to be included in the questionnaire: uniformity of design, use of “swear words”, visual content (images of “realistic people”), etc. An approximate structure of the future questionnaire is also presented.

The effect of sports expertise on the performance of orienteering athletes’ real scene image recognition and their visual search characteristics

As a sport conducted in dynamically changing natural environments, orienteering places high demands on athletes' cognitive processing abilities and visual search efficiency. However, previous studies on orienteering have been primarily limited by the use of fixed stimulus materials on computer screens, which are unable to fully simulate authentic sports scenarios. To better understand the sports expertise of orienteering athletes in terms of their real scene image recognition performance and visual search characteristics, this study recruited 40 orienteering athletes, both experts and novices, as participants. By utilizing eye-tracking technology and setting observation points in real-world scenarios to conduct image recognition task tests, the ecological validity of the experiment was further enhanced. The results showed that the experts demonstrated a high level of accuracy and a short response time, with visual search characteristics including few saccade counts, low fixation frequency, concentrated fixation points, simple and clear fixation paths, and higher visual search efficiency. This study further reveals that long-term specialized training will lead to the formation of a unique cognitive structure related to the specific knowledge and long-term memory required by expert orienteering athletes, thereby promoting the development of expert advantage.

Not All Stroop-Type Tasks Are Alike: Assessing the Impact of Stimulus Material, Task Design, and Cognitive Demand via Meta-analyses Across Neuroimaging Studies.

The Stroop effect is one of the most often studied examples of cognitive conflict processing. Over time, many variants of the classic Stroop task were used, including versions with different stimulus material, control conditions, presentation design, and combinations with additional cognitive demands. The neural and behavioral impact of this experimental variety, however, has never been systematically assessed. We used activation likelihood meta-analysis to summarize neuroimaging findings with Stroop-type tasks and to investigate whether involvement of the multiple-demand network (anterior insula, lateral frontal cortex, intraparietal sulcus, superior/inferior parietal lobules, midcingulate cortex, and pre-supplementary motor area) can be attributed to resolving some higher-order conflict that all of the tasks have in common, or if aspects that vary between task versions lead to specialization within this network. Across 133 neuroimaging experiments, incongruence processing in the color-word Stroop variant consistently recruited regions of the multiple-demand network, with modulation of spatial convergence by task variants. In addition, the neural patterns related to solving Stroop-like interference differed between versions of the task that use different stimulus material, with the only overlap between color-word, emotional picture-word, and other types of stimulus material in the posterior medial frontal cortex and right anterior insula. Follow-up analyses on behavior reported in these studies (in total 164 effect sizes) revealed only little impact of task variations on the mean effect size of reaction time. These results suggest qualitative processing differences among the family of Stroop variants, despite similar task difficulty levels, and should carefully be considered when planning or interpreting Stroop-type neuroimaging experiments.

Исследование линейности цветовосприятия человека в графическом интерфейсе систем управления

The work is aimed at studying the process of human perception of visual information in conditions of interaction with a certain interface. The authors describe experimental research of the linearity of human colour perception in the graphical interface of control systems when observing colour pictograms in a conditional interface. To analyze the mechanism operation of the visual information perception, an information model of visual perception is used. Features of human perception of visual information can be of both an individual nature associated with a specific individual, and an external nature associated with the systemic interference of the operator’s direct interaction with the interface. The paper defines the factors of the study and describes the methodology for preparing stimulus material using the Processing programming language. As a tool for conducting the experiment, a software and hardware complex recording oculomotor activity Eye-tracker SMI RED 250 is used. The importance of creating effective user interfaces for control systems of complex objects and insufficient study of adapting interfaces to the features of human perception of visual information at the perceptual level of awareness determine the relevance of the study. The means of mathematical statistics process the obtained parametric data of the template for examining the stimulus material. The results got in the experiment allow concluding that the mechanism of human visual information perception, when the colour spot brightness decreases, remains sensitive to yellow colour the longest.
