Brain Responses to Dynamic Facial Expressions: A Normative Meta-Analysis
Identifying facial expressions is crucial for social interactions. Functional neuroimaging studies show that a set of brain areas, such as the fusiform gyrus and amygdala, become active when viewing emotional facial expressions. The majority of functional magnetic resonance imaging (fMRI) studies investigating face perception typically employ static images of faces. However, studies that use dynamic facial expressions (e.g., videos) are accumulating and suggest that a dynamic presentation may be more sensitive and ecologically valid for investigating faces. By using quantitative fMRI meta-analysis the present study examined concordance of brain regions associated with viewing dynamic facial expressions. We analyzed data from 216 participants that participated in 14 studies, which reported coordinates for 28 experiments. Our analysis revealed bilateral fusiform and middle temporal gyri, left amygdala, left declive of the cerebellum and the right inferior frontal gyrus. These regions are discussed in terms of their relation to models of face processing.
The paper reviews contemporary research of group helping behavior - help for some members of outgroup or outgroup as a whole. Various forms of selfish helping (help, contrary to stereotypes, defensive help) and factors of intensity of the helping behavior are analyzed. In conclusion, describes the limitations of existing studies
The paper considers semantic structure of emotion causatives and their interaction with negation, namely, its narrow or wide scope. Emotion causatives are defined as a group of causatives with their specific semantic properties that distinguish them from other groups of causatives. One of those properties concerns their relation with corresponding decausatives, which, unlike causatives, do not license wide scope of negation. There are several factors that enable negation to have scope over the causative element in emotion causatives – their imperfective aspect, generic referential status of the causative NP phrase, agentivity and conativity of the causative. Non-agentive causatives never license the negation of the causative component. Agentive conative causatives license the negation of the causative component more frequently and easily than agentive non-conative causatives, prompting the assumption that in their semantic structures the causative component has different statuses (assertion in the former, presupposition in the latter). It also has different forms for conatives and non-conatives. Conativity vs. non-conativity of emotion causatives is related to the emotion type, with conative synthetic causatives being limited to basic emotions. The greatest degree of conativity and, hence, the assertive status of the causative component characterizes three emotion causatives – zlit’ ‘to make mad’, veselit’ ‘to cheer up’, and pugat’ ‘to frighten’.
Key words: causative, decausative, agentive, conative, intentional, presupposition, assertion, semantic structure, basic emotions
The paper presents corpus-driven semantic analysis of Russian classic elegy introduced in poetic heritage of V. Zhukovsky, E. Baratynsky, and A. Pushkin. Contemporaries criticized classic elegy for eulogizing sadness and disappointment, and even claimed sorrow as a genre feature. This study addresses correlations between common impression of sorrow and actual emotional nominations in lyric of three Russian masters of the classy elegy. Сontrary to all expectations, the most diverse emotional nominations denote joy and happiness, whereas lexemes referring to sorrow and anxiety are less frequent. The analysis also reveals stylistic distinctions between the poets. While emotional nominations of Pushkin's and Zhukovsky's elegies mostly councide, the Baratynsky's elegies demonstrate narrow spectrum of feelings and mostly concentrate around love rather than philosophical meditation and emotional distress.
We analyzed brain functional connectivity using data from a task-based fMRI study of explicit categorization of neutral and emotional faces. During the perception of emotional faces, the correlation of BOLD signal in the right posterior superior temporal sulcus (STS) with other regions of the core face system increased, as compared to neutral faces. Conversely, during the perception of neutral faces, we found an increased correlation of STS and other core face system regions with brain areas outside the core system. The functional connectivity of STS shows lateralization due to the presence or absence of emotional expression. The obtained results support the key role of STS in facial expression recognition.
Meaningful life is emotionally marked off. That’s the general point that Johansen (IPBS: Integrative Psychological & Behavioral Science 44, 2010) makes which is of great importance. Fictional abstractions use to make the point even more salient. As an example I’ve examined Borges’ famous fiction story. Along with the examples of Johansen it provides an informative case of exploring symbolic mechanisms which bind meaning with emotions. This particular mode of analysis draws forth poetry and literature in general to be treated as a “meaningful life laboratory”. Ways of explanation of emotional effect the art exercises on people, which had been disclosed within this laboratory, however, constitute a significant distinction in terms that I have designated as “referential” and “substantive”. The former appeals to something that has already been charged with emotional power, whereas the latter comes to effect by means of special symbolic mechanisms creating the emotional experience within the situation. Johansen, who tends to explain emotions exerted by the art without leaving the semiotic perspective, is drawn towards the “referential” type of explanation. Based upon discussions in theory of metaphor and Robert Witkin’s sociological theory of arts it is demonstrated an insufficient of “referential” explanation. To overcome a monopoly of “referential” explanation of emotional engagement, in particular, in literature, means to break away from the way of reasoning, stating endless references to “something else”, presupposing the existence of something already significant and therefore sharing its effects.
Literature review of modern experimental studies of emotion effects on attention.
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.
