The article presents the results of an experimental pilot study on a domestic sample of undergraduates, the purpose of which was to study the connection between creativity and the lateral dominance of the brain organization. The relevance of the study is dictated by the need to develop creativity at a university as a key skill of the 21st century, taking into account individual resources of creative potential, including cognitive and psychophysiological ones. The results obtained make it possible to assess the validity of identifying the dominant right hemisphere over the left as a predictor of creativity. Empirical data on the dominant hemisphere of the brain were obtained based on the use of three psychomotor tests, and data on the level of creative, divergent thinking were obtained using verbal and non-verbal Torrance subtests. The study involved two independent experimental samples - undergraduates in technical and humanitarian specialties. The division of the total sample according to this criterion is due to the widespread idea that people with predominant imaginative thinking are inclined towards humanitarian professions, and verbal-logical ones - towards technical ones. A comparative analysis of the levels of divergent thinking in right- and left-hemisphere undergraduates in both groups and an assessment of the reliability of differences using Fisher's multifunctional φ*-criterion (angular transformation) were carried out. The verification results in both groups did not confirm at a significant level the statistical hypotheses about the functional significance of the left hemisphere in divergent thinking among undergraduates. Empirical evidence suggests that differences in lateral hemispheric dominance are not a barrier to divergent thinking as a cognitive aspect of creativity.
