The time course of retaining the hierarchical representation in visual working memory
The chapter juxtaposes Veselovsky’s theory of the persistence of forms with the set of critical practices known as New Historicism, and shows that both approaches exclude the possibility of new forms arising. The chapter suggests that both the oblivion of an old form and the rise of the new result from a fundamental shift in perception that occurs within the order of verbal creativity and does not lend itself to a historical-deterministic explanation.
There are two factors influencing on representation of revolutionary events of 1917 in the popular TV-series in the post-Soviet Russia. First, it is the negative revaluation of revolution which took place in public discussions of the 1990th when both the dominating elite, and opposition expressed equally negative relation to this event. Subsequently this position was then developed in historical policy of Vladimir Putin who, though having proclaimed the doctrine of the “total continuity” (connecting pre-revolutionary, Soviet, and democratic values), has been never hiding suspicious attitude toward the October revolution. For mass culture this meant permission to include “dark sides” of the history of revolution in popular narratives, that was impossible during the Soviet period (for example, the facts of cooperation of Bolsheviks with criminals). Secondly, the “popular cultural memory” about revolution created by means of Soviet feature films had paradoxically the contradictory character as well as
initiated a number of reinterpretations of this event in post-Soviet cinema of the 1990-2010th. Soviet films represent revolution as, first of all, a civil war made for the sake of the future, for the sake of a new society and implementation of the revolutionary ideals. “Memory of revolution” in this case was consciously constructed with emphasis on its “validating” function which was necessary for legitimization of the current political situation in the Soviet state. Such films were made generally during the 1930th – 1950th. In the period of the “Thaw” some films proposed different approaches to revolution, and many of them were not permitted to screen until the 1980th. The different film versions of revolution became available for a wide audience beginning from the middle of the 1980th, when the year 1917 was represented as a changeable, illusive and ambiguous “place of memory”. In the article the character and content of TV-representations of revolution created during the post-Soviet period in the context of wider “policy of identity” are analyzed.
Previous research has documented the limited capacity of visual working memory (VWM) for color objects set at 3–5 items. Another line of research has shown that multiple objects can be stored in a compressed form of ensemble. However, existing data is more likely to testify that VWM can store no more than two such compressed units. But the nature of this discrepancy can be methodological: VWM for ensembles was never tested using methods that are applied in the research of VWM for objects. Here we have tested the capacity and precision of VWM for objects and ensembles using two standard methods — change detection and continuous report with a mixture model. We found that VWM for both types of units showed the similar capacity and precision when critical psychophysical parameters, such as foveal density and area are controlled. We also showed that this quantitative similarity between objects and ensembles is provided by a mechanism that represents each ensemble as a holistic VWM chunk as efficiently as it represents any single object.
This article reviews the research in visual working memory (VWM) over the past 20 years. We describe research methodologies in the field and focus on commonly used paradigms such as change detection and continuous report (including the use of mixed models for analysis) that aim to measure the capacity and precision of VWM. We also consider the organization of units of storage in VWM; in particular, we describe feature binding and representing multiple objects as ensemble summary statistics. We review theories that try to explain the nature of VWM limitations: structural theories (slot-based), resource theories, hybrid theories (slot and resource theories), and a recently suggested hierarchical encoding theory. Theories aiming to explain forgetting mechanisms in VWM are reviewed. We also discuss the neural correlates of VWM encoding and storage, as well as neurophysiological models of VWM that are substantially influenced by the mentioned theories.
The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
This article describes the expierence of studying factors influencing the social well-being of educational migrants as mesured by means of a psychological well-being scale (A. Perrudet-Badoux, G.A. Mendelsohn, J.Chiche, 1988) previously adapted for Russian by M.V. Sokolova. A statistical analysis of the scale's reliability is performed. Trends in dynamics of subjective well-being are indentified on the basis the correlations analysis between the condbtbions of adaptation and its success rate, and potential mechanisms for developing subjective well-being among student migrants living in student hostels are described. Particular attention is paid to commuting as a factor of adaptation.
