In the study presented in the paper, the term passion for computer games and viewing social networks is used as a predictor of computer addiction and, which is not legally defined as addiction, but its blocking effect on the educational activity and productivity of schoolchildren can be stated. The study was carried out in accordance with the ecopsychological model of the formation of subjectivity from the subject of perception to the subject of productive development. The aim was to study the possible links between the passion for computer games and social networks, and such a state of personality, which in everyday consciousness is defined as laziness of schoolchildren. In accordance with the understanding of the formation of subjectivity (the subject of productive development) in the ecopsychological model, the key condition is human activity. We suggested that the lack of activity or passivity of students in grades 8-11 may be a condition for the emergence of excessive enthusiasm for computer games and viewing social networks. Two authors methods were used: Personal characteristics as predictors of abnormal behavior and Laziness or unwillingness to learn, the creation of which is associated with the need to study the intrapersonal causes of passivity or lack of activity in educational activities or the phenomenon of learning laziness in students. The hypotheses are confirmed by the fact that Spearmans correlation coefficients were obtained, showing statistically significant links between computer and social media involvement with all the identified causes of laziness, namely: reduced learning motivation, lack of self-confidence, attitudes that everything does not depend on me, so there is nothing to try, poor health, lack of conscious self-regulation, dissatisfaction with the attitude of teachers. Spearman coefficients from .326 to .421 at p 0.001. In general, the results obtained confirm the theoretical validity of the developed methods and show the validity of their use for psychological and pedagogical support for the development and formation of subjectivity of high school students.

Otoconia are microscopic geometric structures that cover the sensory epithelia of the utricle and saccule (gravitational receptors) of mammals, and the lagena macula of birds. The importance of otoconia for maintanance of the body balance is evidenced by the abnormal behavior of species with genetic defects of otolith. Although a few reports have dealt with otoconia formation, some basic questions remain unanswered. The chick embryo is desirable for studying otoconial formation because its inner ear structures are easily accessible, and its gestational period is short (21 days of incubation).The results described here are part of an intensive study intended to examine the morphogenesis of the otoconia in the chick embryo (Gallus- domesticus) inner ear. We used chick embryos from the 4th day of incubation until hatching, and examined the specimens with light (LM) and transmission electron microscopy (TEM). The embryos were decapitated, and fixed by immersion with 3% cold glutaraldehyde. The ears and their parts were dissected out under the microscope; no decalcification was used. For LM, the ears were embedded in JB-4 plastic, cut serially at 5 micra and stained with 0.2% toluidine blue and 0.1% basic fuchsin in 25% alcohol.

The present study investigated whether a social information processing bias contributes to the inverse association between trait hostility and perceived social support. A sample of 104 undergraduates (50 men) completed a measure of hostility and rated videotaped interactions in which a speaker disclosed a problem while a listener reacted ambiguously. Results showed that hostile persons rated listeners as less friendly and socially supportive across six conversations, although the nature of the hostility effect varied by sex, target rated, and manner in which support was assessed. Hostility and target interactively impacted ratings of support and affiliation only for men. At least in part, a social information processing bias could contribute to hostile persons' perceptions of their social networks.
