Does Playing Video Games Increase Emotional Creativity?

Emotional creativity (EC), which constitutes a main aspect of the general creativity concept, is often shown to be substantially related to positive emotional experiences, effective motivation, and innovation at the workplace as well as at school. However, little is known about the relationship between emotional creativity and the time people tend to spend playing video games. Nowadays, video games and virtual reality have become an important aspect of public health and psychological research. They constitute a key element of popular culture and generate considerable economic profit as part of the public entertainment industry. Our study is based on the results of an emotional creativity inventory (ECI) survey that was administered at a snowball and convenient sample of 453 respondents (aged 18-60 years, M ± SD: 23.68 ± 6.36; 66.40% women, 20.00% with higher education) from the Czech Republic who were questioned about their habits and the time they devote to playing video games. The sample country was selected as one with a long tradition of homebrew video gaming going back to the 1980s. We employed a set of multinomial regression analyses, which revealed that more time devoted to playing video games is associated with lower emotional creativity, in general, as well as with lower novelty, preparedness, and effectiveness components of emotional creativity. The negative association above was less pronounced for women than for men. Moreover, in a sample containing only women, a longer time devoted to playing video games was associated with the higher novelty component of emotional creativity (the associations with the other two components were not statistically significant for women only). Our findings might considerably contribute to the study of the general overall long-term effect of video games and the use of digital technologies in general on public health.

Research of gnostic functions in the elderly people suffering from dementia

The study was aimed at investigating the features of gnostic functions in the elderly people suffering from dementia. To implement the objectives of the study and to solve the set tasks, the following methods were used: visual gnosis tests (recognition of images, the selection of three subject pictures, selecting parts of a whole, etc.), the acoustic gnosis tests (score and perception of rhythms, recognition of nonspeech sounds), and tactile gnosis tests (tactile identification, Teuber test, Foerster test). When running the visual gnosis tests, the elderly people with the dementia diseases slowly initiated the tasks, made numerous errors, and sometimes could not cope with the tasks at all. Also, the perception integrity disorders, the presence of fragmentation, lack of accuracy, differentiation, preservation of specific objective images-objects, and the violation in the understanding of the spatial arrangement of things were revealed. When performing the auditory-motor coordination tests, the elderly people suffering from dementia needed more time to listen to, they asked for the repeated sound representation, and there were often errors in the rhythmic structure reproduction. When performing the tactile gnosis tests, the elderly people suffering from dementia had difficulties in identifying the subject by touch, in understanding the right and left-sided spatial relationships, and also made errors in recognizing one of the touches when the experimenter touched their hands. Based on the study results, the recommendations have been developed for the preservation and improvement of the existing gnostic functions' disorders in the elderly people suffering from dementia. The recommendations are complex, and they can also be useful for the medical staff whose professional activity is directly related to the elderly people suffering from dementia, their relatives and the persons closest to them.

Genetic variability of 15 autosomal STR loci in Russian populations.

Allele frequencies for 15 STRs (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, THO1, TPOX, and vWA) in the PowerPlex 16 System (Promega Corporation) were assessed in 386 individuals from five Russian urban populations. No significant between-population differences in frequencies and molecular variance of 15 microsatellites were revealed. For all 15 loci, the combined matching probability is 3.19 x 10(-18) and the power of exclusion is 99.99989%.
