The article describes the results of the study of the emotional well-being of preschool children and its connection with the parental resilience. An empirical study was conducted on the basis of pre-school institutions in Moscow, using diagnostic methods: tests – for parents and teachers; projective tests – for children whose results were analysed using computer statistical methods in the computational methods of statistical data processing. As a result of the study, the signifi cance of the problem of resilience in the context of modern digital environment and the theoretical concept of «emotional well-being of children» and its components are clarifi ed. A set of diagnostic methods for express diagnostics of the child’s emotional well-being in a preschool educational institution has been selected and modifi ed. Two questionnaires were developed (for parents and for teachers) to assess the emotional well-being of preschoolers. A signifi cant relationship was found between indicators: emotional well-being of preschool children and the parental resilience; features of child-parent relations, features of marital relationships. Using factor analysis, three groups of children with different levels of emotional well-being and three groups of parents with different levels of resilience, with children with low, medium and high levels of emotional well-being, are identifi ed and described.

Emblematics in the Viceroyalty of Peru functioned as an intertextual system that established connections between models of emblems already consecrated and the shared use of symbols, Latin phrases and compositions that are related to —but also oppose and divert from— Western symbolic traditions. Hypomnema apologeticum pro Academia Limensi, by jurist Diego León Pinelo (1608-1671), and Tratado de los Evangelios, by the slayer of idolatries and Canon of the Cathedral of Lima, Francisco de Ávila (1573-1647), both published in Lima in 1648, had each front covers that are analyzed based on the visual set they incorporate, which is made up of allegorical images and emblems, and their contexts of production. The vice-regal visual rhetoric reveals that it was not only aimed at exalting monarchical and counter-reformist power and politics, but also at developing the identity of the artists in charge of the engravings. Paradoxically, both images can be considered as a failure on different levels, but also as a triumph within the symbolic struggle of every affirmation of identity whose verb-visual rhetoric remains fixed in memories that many people could decipher.

Functional Stress

The changes in the electrical activity of the brain of boys with different tempo-rhythmic characteristics of speech during functional stress have been studied, namely, a series of flashes of light of a certain frequency – rhythmic photostimulation have been used. The bioelectrical activity of the brain has been studied using a computer electroencephalography system. Also, according to the methodology of zonal distribution of normalized spectral power (SP) of the rhythm of the main frequency of the EEGranges, the particles (in percent) of the normalized SP of electrogenesis in each of the four main ranges (δ, θ, α, β) have been determined. As a result of comparison of the light flashing frequency assimilation among boys in the studied groups, it has been found, that in the group of children with logoneurosis slow rhythms (5 Hz,) lying within the theta-range of the EEG, were better assimilated. The rhythm is assimilated in the low frequency range among the children with logoneurosis. The relative spectral power of theta-rhythm significantly decreased on the EEG of children with tempo and rhythm speech disorder at low-frequency photostimulation in comparison with the corresponding indicators of the background electroencephalogram; the corresponding indicators in the beta-range, anterior and posterior leads in the alpha-rangeincreased. Based on the obtained data, it has been found, that children with logoneurosis have insufficient response to photostimulation. Such data are associated with insufficient inhibitory effect of the cortex on the subcortical structures. The reduced reactivity and functional insufficiency of the activating system of the brain stem have been noted. Neurophysiological mechanisms of logoneurosis are due to the state of insufficient formation of brain structures, which is confirmed by the results of electroencephalography during rhythmic photostimulation. Changes in the tempo and rhythm of speech during logoneurosis of preschool children provoke stress of the brain mechanisms of regulation, which become apparent by special characteristics of the electrical activity of the brain, both at rest and during load.
