Brain mechanisms of persuasion: how 'expert power' modulates memory and attitudes
Human behaviour is affected by various forms of persuasion. The general persuasive effect of high expertise of the communicator, often referred to as ’expert power’, is well documented. We found that a single exposure to a combination of an expert and an object leads to a long-lasting positive effect on memory for and attitude towards the object. Using functional magnetic resonance imaging, we probed the neural processes predicting these behavioural effects. Expert context was associated with distributed left-lateralized brain activity in prefrontal and temporal cortices related to active semantic elaboration. Furthermore, experts enhanced subsequent memory effects in the medial temporal lobe (i.e. in hippocampus and parahippocampal gyrus) involved in memory formation. Experts also affected subsequent attitude effects in the caudate nucleus involved in trustful behaviour, reward processing and learning. These results may suggest that the persuasive effect of experts is mediated by modulation of caudate activity resulting in a re-evaluation of the object in terms of its perceived value. Results extend our view of the functional role of the dorsal striatum in social interaction and enable us to make the first steps toward a neuroscientific model of persuasion.
The article focuses on investigation of personal attitudes toward oppositions of life. This research is following the principles of psychology of personal life attitudes and cultural psychology of personality. Some ways of explication of psychological knowledge about intuitive and reflexive personal attitudes to oppositions from cultural sources are suggested. As a data for hermeneutic analysis, texts of folk tales and Renaissance self-cognition text are provided. Author concentrates on self-developing and self-forming aspects of personal attitude to life oppositions.
Formation of democratic societies of the Western type presupposes appearance on the historical scene of a new strong actor - the bourgeois class: "No bourgeoisie, no democracy" (Barrington Moore). The articulation and defense of vital interests of that class creates a new social space - "the bourgeois public sphere" which helps to make up "counterbalance" to absolutism of a corporate state - a civil society, the core of which is composed by public opinion. In the confrontation between the authorities and society one of the most important roles is played by the press that provides free debate and discussion of generally valid problems, especially economic and political. The recognition of the mass media role was stamped in its characterization in XIII century as "the fourth power". Technological development of the media incredibly expanded its functions, turning journalists into creating informational analogue of reality, saturating daily life with new meanings. Methods of the representation of reality, the specific nature of political influence of journalists - key members of the reflexive elites (Helmut Shelski), are the themes of this article.

The article argues that political texts should be view as both reflecting current social and political reality and cunstructing it at the same time through what can be called biased interpretations. The article analyses a number of language choices in political texts that can lead to construction of biased interpretations and add to creation of so called political myths.
This book addresses a subject that can in the broadest sense be stated as interplay of language and ideology in process of instantiating historical knowledge in texts of political significance. The aim of the present volume is to discuss how history is recontextualized in national political discourse in the framework of two basic strategies of in-group and out-group categorization and biased representation of historical facts. It is contended that such recontextualization leads to what can be described as blending of national political discourse with a nationalistic one.
The evidence for the above contention is provided through linguistic analysis of three chunks of texts.
First, American presidential rhetoric spanning the last 50 years of history was analyzed. This part of the analysis suggests that a productive way to analyze the ‘enemy construction’ strategy seen as one of the key strategies of the discourse of the New World Order is to analyze it in a broader historic perspective, viz. as taking over the same principles, which defined the discourse of the Cold War. The ‘enemy construction’ strategy in both discourses is analyzed as resting on logic of binarism of the classical Us and Them opposition. Thus, it is contended that textual actualization of the ‘enemy’ is the projection of the basic category of the ‘other’ which is perpetuated in the political discourse and gets lexicalized differently depending on the text’s instantiating a particular order of discourse and the ideology informing it.
Second, a chunk of texts produced by those claiming to be professional historians has been addressed to see how national historical discourse is reinstantiated vis-à-vis a newly acquired national identity. An example of such discourse would be texts by Ukrainian historians writing on Great Patriotic War/World War II.
Third, texts of public figures, state leaders among them, instantiating post-Soviet geopolitical situation in the Caucasus, in particular, tension between Armenia and Azerbaijan over Nagorny Karabakh were looked into. The tension aggravated with unresolved conflicts, involvement of both Russia and the USA, results in this material being a valuable source for pinpointing linguistic patterns of historical and political discourse in general and patterns indicative of national historical discourse transforming into nationalistic discourse, in particular.
Discourse analysis is neither meant to substitute historical analysis, nor claims that all historical permutations are of discursive nature solely. Instead, we see the role of discourse analysis in placing a broader question: To what extent that which has really happened is displaced by its recontextualization in discourse, i.e. by its description? Since any conflict is always closely tied with conflicting values the question can be restated as: To what extent in such historical accounts accurate rendition is displaced with evaluation and appraisal? What comes first: the unresolved issues themselves or discursive practice perpetuating those issues? In other words, is it the conflict itself or the conflict of conflicting textual descriptions?
One way or the other, historical representations are not static; they are flexible and more than prone to distortion when values come into play. Reinventing the history to mesh with a new national identity is number one example. A clash of different political perspectives is a clash of different historical descriptions. And in this clash a power-wielding social agent has the power to reinterpret the history that will fit their political narrative with other interpretations outlawed and rendered unhistorical.
In the meantime, the true power of history as a field of study and an academic discipline should be seen in presenting multiple interpretations of phenomena in question with these interpretations being mutually complementary rather than mutually exclusive. In which lies the real power and the mission of all the humanities.
The author considers the term «compensative expertise» and its role in successful language mastering.
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.
The general aim of this thesis is to explore the gendered and classed nature of social work and social welfare in Russia to show how social policy can be a part of and reinforce marginalisation. The overall research question is in what ways class and gender are constructed in Russian social work practice and welfare rhetoric through Soviet legacies and contemporary challenges? In addition, which actors contribute to the constitution of social work values and how this value system affects the agency of the clients? This study focuses on contradictory ideologies that are shaped in discursive formations of social policy, social work training and practice. It is a qualitative study, containing fi ve papers looking at this issue from three different perspectives: policy and institutions, culture and discourse, actors and identity. The data collection was arranged as a purposive–iterative process. The empirical material consists of qualitative interviews with social work practitioners, administrators and clients, participant observations in social services and analysis of documents of various kinds.
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.
Hypoxia of trophoblast cells is an important regulator of normal development of the placenta. However, some pathological states associated with hypoxia, e.g. preeclampsia, impair the functions of placental cells. Oxyquinoline derivative inhibits HIF-prolyl hydroxylase by stabilizing HIF-1 transcription complex, thus modeling cell response to hypoxia. In human choriocarcinoma cells BeWo b30 (trophoblast model), oxyquinoline increased the expression of a core hypoxia response genes along with up-regulation of NOS3, PDK1, and BNIP3 genes and down-regulation of the PPARGC1B gene. These changes in the expression profile attest to activation of the metabolic cell reprogramming mechanisms aimed at reducing oxygen consumption by enabling the switch from aerobic to anaerobic glucose metabolism and the respective decrease in number of mitochondria. The possibility of practical use of the therapeutic properties of oxyquinoline derivatives is discussed.
