“…Most correlations are, admittedly, relatively modest. But they are significant enough to allow us, like Hoppe and Kyle (1990), to regard creativity as a crucial factor in psychosomatics and to let the findings elucidate creative characteristics. At the same time, it should be remembered that creativity in most computations presented here encompasses moderate signs (0) besides strong ones (X).…”

“…Low-creative persons are known to use mainly analytical verbal strategies and semantic memory while solving a divergent task, while highly creative subjects use the visuospatial strategy and episodic memory [16,34]. Ample evidence has been obtained for right-hemispheric dominance in creative thinking [26][27][28]. In our study, these findings were confirmed by the maps of coherent connections in the β 2 band: more active involvement of the left hemisphere in DTh was observed (along with a predominantly left-hemispheric location of Coh foci) in GR0, while a stronger interaction of the cortical areas in the right hemisphere was detected for GR1.…”

“…On the basis of comparative examination of commissurotomized patients and healthy subjects, it has been suggested that creativity is caused by simultaneous symbolization of ideas and their imagery in the right hemisphere, accessible to the left hemisphere via the corpus callosum [26]. Thus, the ideas of the righthemispheric dominance do not contradict the known facts of a closer interhemispheric interaction in creative processes.…”

Gender dimorphism is inherent in various cognitive activities, including convergent (CTh) and divergent (DTh) thinking [1,2]; however, features of the functional hemispheric lateralization characteristic of men and women [3][4][5] during solving mathematical (CTh) or creative (DTh) tasks remain unstudied. Considering that gender differences in brain activity have been observed even in the case of equal efficiencies of cognitive performance [5,6], analysis of the frequencyspatial EEG organization during CTh and DTh may be useful for revealing features of the functional interhemispheric interaction in men and women. Guilford [7] proposed the model of DTh for describing the creative type of thinking, implying many solutions of a problem, each of which can be correct, in contrast to CTh, with a single correct solution. Investigation of inter-and intrahemispheric interactions by mapping coherent connections between different cortical areas is of special interest with such models because they offer a possibility of direct observation of convergence or divergence of neuronal connections depending on the test conditions.It is well known that, in general, men perform arithmetic IQ subtests better than women [1,8,9]. However, although a number of articles are concerned with the neurophysiological mechanisms of mathematical operations [10-13], their gender-related features are scarcely considered in these works. At the same time, high specialization of the brain hemispheres during the performance of verbal and spatial tasks has been found in men [4,5]. This fact suggests that convergent processes are more pronounced in men and, consequently, success in solving of mathematical (convergent) tasks by men and women is also associated with genderrelated features of interhemispheric interactions.Analysis of the gender-related features of interhemispheric interactions during DTh (creative thinking) provokes still greater interest. It has been shown that interhemispheric asymmetry is weaker in highly creative than in low-creative subjects [14][15][16][17][18]. At the same time, a closer interhemispheric interaction has been observed in women compared to men [19][20][21]. Consequently, gender differences in hemispheric interaction may be expected for DTh. Indeed, investigation of the cortical mechanisms of creativity has established that the performance of a verbal task in men is associated with an increase in interhemispheric coherence (Coh) between the right posterior and left frontal cortical areas, whereas a stronger connection between the left posterior and right frontal and mediotemporal areas has been observed in women [22]. Analysis of the EEG spatial organization in two α bands has shown that, during composing a story, intrahemispheric Coh in the α 1 rhythm in the left hemisphere increases only in women. Also, Coh increases between the centroparietal sites in Abstract -The gender dependence of inter-and intrahemispheric interactions of neuronal assemblies during convergent (CTh) and divergent (DTh) thinking was studied on ...

“…It is likely that practicing activities such as music, dance, theatre, visual arts, and writing may amplify emotional experiences and facilitate translations of emotions, and thereby reduce alexithymia. Significant relationships between alexithymia and two different aspects of creativity (creative capacity and fantasy proneness) have been described (Fuchs, Kumar, & Porter, 2007;Hoppe & Kyle, 1990). Our own group has studied the relationship between amount of music practice and alexithymia and between dance achievement and alexithymia (Bojner Horwitz, Lennartsson, Theorell, & Ullen, 2015;Theorell et al, 2014), but separate and joint statistical contributions to alexithymia of all the five domains of artistic achievements in one and the same study have not been analysed before.…”

Alexithymia is characterized by deficits in the ability to identify, differentiate, and describe emotions-abilities that are of importance for social interactions, well-being, and, consequently, also for health. The aim of this study was to investigate whether achievements in cultural activities are associated with alexithymia. Participants from the Swedish Twin Registry were 2,279 men and 3,152 women in the ages 27 to 54. Cultural achievement was measured with the Creative Achievement Questionnaire (CAQ) in which participants estimate their achievement in the domains writing, music, visual arts, theater, and dance on a 7-point scale. Alexithymia was measured with the Toronto Alexithymia Score (TAS 20). In sex separated, age, and educationadjusted multivariate analyses, nonpractitioners, amateurs, and professionals in the 5 different CAQ domains were compared with regard to alexithymia scores. For both men and women, achievement in writing and music contributed statistically and independently of one another to a low alexithymia score. In addition, achievement in visual arts contributed independently to low alexithymia score in men and achievement in theatre to low alexithymia score in women. Total creative achievement was calculated as a sum score across domains, and the distribution divided into tertile groups. These groups were compared with regard to alexithymia scores. Large tertile differences were found in both sexes. The results show differences between modalities and cumulative effects of multiple creative achievements.
