Attentional priming does not enable observers to ignore salient distractors
It is commonly assumed that we find targets faster if we know what they look like. Such top-down guidance plays an important role in theories of visual attention. A recent provocative proposal is that effects attributed to top-down guidance instead reflect attentional priming.
Top-down guidance of visual search is an issue of continuous discussions (e.g. Wolfe, Horowitz, 2017). However, it’s still unclear when guidance emerges in the course of individual development, and whether the fronto-parietal brain network, which underpins attentional control, is necessary for the attentional guidance. Although there were a number of experiments studying visual search in children, to our knowledge no study directly confronted conditions, under which adults do and do not demonstrate guided search, in younger populations. In our experiment, we compared feature search, guided conjunction search and unguided conjunction search in 20 young adults (university students, mean age 18.5) and 20 junior schoolchildren (7.5–9.5 years old, mean age 8.5). The two groups performed three randomized blocks of the standard visual search task, searching for a target “fox’s house” among distractor houses and receiving feedback after each trial. The target house differed from distractors only in color (feature search), in color and shape (conjunction search), or was defined as a specific combination of two colors (conjunction search with no possibility of top-down guidance). Set sizes of 4, 7, and 10 stimuli were used, with only a half of the trials containing a target. Our hypothesis was that in adults we would observe top-down regulation of the conjunction search, whereas in children the search besides the feature search condition will be equally inefficient, because of the fron-to-parietal network immaturity (e.g. Astle et al., 2015). Surprisingly, the overall pattern of results in all three conditions was the same in children and adults, with pronouncedly more efficient conjunction search as compared to the unguided search, although children were significantly (and proportionally) slower in all types of search. This allows concluding that top-down attentional guidance is already fully present in junior schoolchildren.
The heterogeneity of our visual environment typically reduces the speed with which a singleton target can be found. Visual search theories explain this via nontarget similarities and dissimilarities that affect grouping, perceptual noise, etc. Here, we show that increasing the heterogeneity of a display can facilitate rather than inhibit visual search for size and orientation singletons when heterogeneous features smoothly fill the transition between highly distinguishable nontargets. We suggest that this smooth transition reduce the “segmentability” of dissimilar items to otherwise separate subsets making the visual system to treat them as a near-homogenous sets opposing to a singleton.
The subject of this article is the debate of Gadamer and Habermas about the nature of critical thinking, the relationship between freedom and authority, the individual and traditions, documented in the book “Hermeneutics and criticism of ideology” (1971). Central to the author is the question: «What understanding of critical thinking would allow us to gain a higher degree of resistance to ideology?» Approaching the answer to this question is carried out as several tasks are successively resolved. First, the author clarifies the meaning and significance of the key concepts of “ideology” and “criticism” in the critical theory of Frankfurt School and philosophical hermeneutics. Thanks to these explanations, becomes clear the basis for the possibility of a productive polemic between philosophical hermeneutics and critical theory. Secondly, in the analysis of the main lines of criticism by Habermas against the hermeneutical project of Gadamer, the author explicates the strengths and weaknesses in the argumentation of the opposing parties. The focus here is the problem of the relationship of critical reflection with prejudice, authority and tradition, the problem of theoretical maturity and methodological support of hermeneutics, the problem of forming a basic consensus of understanding and interaction. Based on a comparative analysis of the arguments and counterarguments of Gadamer and Habermas, the author shows the non-trivial nature of critical thinking and reveals new aspects in understanding the concept of criticism of ideology. The result of the comparative analysis is the idea of an integrative concept of ideology criticism, which allows productive use of the strengths of the critical and hermeneutic approaches, and thereby provide a higher resistance to ideology at the collective and individual levels.

Настоящий ежегодник представляет собой десятый том «Системного мониторинга глобальных и региональных рисков», подготовленный в рамках Программы фундаментальных исследований НИУ ВШЭ. Мониторинг глобальных и региональных рисков – многоаспектное научное направление, включающее в себя комплексное исследование экономических, политических, социальных, а также культурных особенностей развития того или иного региона. На страницах Мониторинга рассматриваются вопросы методологии анализа процессов социально-политической дестабилизации в странах Афразийской макрозоны нестабильности, публикуются результаты количественного анализа, моделирования и прогнозирования процессов социально-политической дестабилизации в странах Ближнего и Среднего Востока, рассматриваются сами дестабилизационные процессы в Афразийской макрозоне нестабильности на страновом и региональном уровне в контексте глобального развития и национальных интересов России.
Мы надеемся, что данный выпуск ежегодника будет полезен как специалистам, так и широкому кругу читателей, интересующихся глобальными процессами, кризисами, прогнозами мирового развития.
Another volume in a series of collective works dedicated to the work of A. N. Ostrovsky, his stage interpretation and reception
The article analyzes the issues of the policy regarding intangible cultural heritage, which is carried out in modern Vietnam. The selection of objects that are recognized as cultural heritage at the national level, as well as being promoted to the List of UNESCO World Heritage Masterpieces, is associated with the specifics of constructing the image of national culture. Despite the obvious positive aspects of the work of protecting national traditions, the theme of culture in Vietnam has the ideological significance, and it affects the authenticity of preserved or restored cultural phenomena. The national myth, which is constructed through cultural heritage policies, comes down to the ideas about the antiquity of the Vietnamese nation and its descent from the Hung Kings, and about the antiquity and continuity of the Vietnamese cultural tradition, which dates back directly to the era of the Hung Kings and carries the features of national identity formed at that time. Such a vision of history and culture is not correct, since the Vietnamese culture developed under the influence of Chinese, and Vietnamese ethnogenetic myths in the form that has survived, bear the imprint of Chinese influence. A special place in the construction of the image of national culture is given to song lore. We believe that actions aimed at enhancing the status of musical folklore have the goal of restoring the traditions of performing folk songs and attracting the interest of youth in this form of activity. We think that the availability of folk songs, the performance of which does not require special skills and special equipment, their potential to turn into mass art makes the promotion of song lore a priority for Vietnamese. Rich and diverse musical folklore is becoming the cornerstone in shaping the image of national culture.
