Context and relevance. In recent years, academic stress among high school students has been regarded as a significant risk factor for their well-being and academic achievement, while in the Russian context there is a noted shortage of modern, psychometrically validated methods for its assessment . Objective. The aim of this study is to validate the ...

При всей кажущейся ясности и недвусмысленности понятия «свобода» дать ему исчерпывающую научную дефиницию весьма затруднительно. У каждой отрасли знания свой подход к трактовке этого многоаспектного понятия. В ходе обсуждения, материалы которого вошли в настоящий сборник, свобода рассматривается с позиций философии, социологии, юриспруденции, психологии, нейрофизиологии и т.д.
Участники дискуссии рассуждают о границах свободы воли и субъектности человека, о соотношении свободы и ...

Personality questionnaires do not directly record recurring conduct. Rather, they elicit
task-bounded reports of personality attributions: how respondents characterise themselves
using personality-descriptive content. From this perspective, established associations between
self-esteem and self-reported personality may depend on the evaluative meaning attached to
that content. We tested whether attitudes toward the Big Five traits moderated associations
between self-esteem and corresponding personality reports ...

This study aimed to investigate resting-state neural correlates of math anxiety in high school students using a graph-theoretical approach. Sixty 10th-grade students (35 females; mean age = 16.15 years) participated in the study. Resting-state EEG data were acquired using a 32-channel wireless dry-sensor system (Cognionics Quick-32 series). Math anxiety was assessed using the Abbreviated Math Anxiety Scale. Mean ...

The Liberal Mission Foundation continues to introduce readers to new concepts of democracy and relevant publications. This discussion focuses on the challenges facing democracy in the era of globalization, as addressed in two recent books: *The Backsliders: Why Leaders Undermine Their Own Democracies* by S.C. Stokes (2025) and *Critical Theories and the Postsocialist Challenge: Race, ...

It is generally accepted that the basis of social and legal stability in any society is a consensus on vir tue — the fundamental values of proper behavior, ways of maintaining and reproducing them. And, conversely, the destruction of this consensus is a sign of the loss of stability and divergence of positions of social ...

Hypergraphs provide a natural framework for representing neurophysiological interactions distributed across sets of sensors. A key methodological question is how hyperedges should be defined from frequency-resolved electroencephalography/magnetoencephalography (EEG/MEG) data. We demonstrate a construction strategy in which hyperedges are obtained from canonical coherence (caCOH), an extension of coherence that estimates coupling between multidimensional signal spaces. To ...

This article presents the Russian Language-Monolingual corpus (RusLan-M, v.1.0), a longitudinal multimedia collection of early child speech from two Russian-speaking monolingual children: Tosya (ages 0;10–3;10, 246 recordings) and Yasha (ages 1;04–3;00, 42 recordings). The corpus consists of approximately 41 h (2,454 min.) of video recordings and 35,386 child utterances, available with transcriptions in the CHAT ...

How do we represent sets/ensembles of objects (e.g., apples on a tree) in the visual system? The summary statistics view suggests that the visual system has access only to ensemble summary statistics (the average apple color and its variability). The feature distribution view claims that the visual system has explicit (conscious) access to the entire ...

The perception of a set of objects with variability of features within this group is referred as ensemble perception. The process of rapid visual categorization is the ability to form categorical groups from a set of objects and is based on the mechanism of ensemble perception. The visual system evaluates the variability of features in ...

The article is devoted to the results of a study of the influence of motor activity on the noise reduction mechanism in the perception of an ensemble. The relevance of the problem of studying the influence of motor activity in the perception of an ensemble is determined by the fact that motor activity is a ...

People can rapidly and efficiently categorize the animacy of natural objects. Does this imply that the visual system has an unlimited capacity for processing animacy across the entire visual field? To test this, we generated a set of morphed “animacy continua” between animate and inanimate silhouettes. Observers were shown different ratios of these items (2:1, ...

Recent studies propose that mid-level features could underlie animacy perception. Here we tested whether the ability to estimate ensemble summary statistics for animacy based on high or mid-level features. We used four types of animate and inanimate images (Long & Konkle, 2018): colorful images, greyscale images, silhouettes (contains only recognizable shapes), texforms (unrecognizable images, which ...

It has been shown that multiple objects can be efficiently represented as ensemble summary statistics, such as the average. Recently, Kanaya et al. (2018) demonstrated the amplification effect in the perception of average. Their participants judged the mean size or temporal frequency of ensembles, and they tended to exaggerate their estimates, especially larger set sizes. ...

Prevailing theories of visual working memory assume that each encoded item is stored or forgotten as a separate unit independent from other items. Here, we show that items are not independent, and that the recalled orientation of an individual item is strongly influenced by the summary statistical representation of all items (ensemble representation). We find ...

The knowledge of target features can be used to guide attention in many conjunction searches in a top-down manner. For example, in search for a red vertical line among blue vertical and red horizontal lines, observers can guide attention toward all red items and all vertical items. Items with both features would gain greater activation. ...

We previously showed that people can discriminate multiple intermixed groups of objects based on "segmentability," large gaps between values in feature distributions forming several peaks. Here, we test whether such discrimination is based on local or global sampling. Two arrays of lines of various orientation (O) and length (L) were presented; both had identical feature ...

The visual system can represent multiple objects in a compressed form of ensemble summary statistics (such as object numerosity, mean, and feature variance/range). Yet the relationships between the different types of visual statistics remain relatively unclear. Here, we tested whether two summaries (mean and numerosity, or mean and range) are calculated independently from each other ...

Previous studies have shown that people are good at rapidly estimating ensemble summary statistics, such as the mean size of multiple objects. In the present study, we tested whether these average estimates are based on “raw” retinal representations (proximal sizes) or on how items should appear based on context, such as the viewing distance (distal ...
