[ROLES OF RATIONAL-IRRATIONAL COGNITIVE STYLES IN THE ALPHA RHYTHM REACTIVITY DURING CONVERGENT AND DIVERGENT THINKING].

Changes of the alpha1 and alpha2 rhythms during convergent (addition in the mind) and divergent (heuristic task solving) thinking due to rational and irrational cognitive styles were studied. It is shown that the functional activity of the cerebral cortex during convergent thinking was associated with rational style and presented in parietal low-frequency alpha1 biopotentials whereas during divergent thinking - with the irrational, and this effect was produced by widespread regional and frequency differences of alpha1 and alpha2 oscillations in posterior cortex. The originality of ideas correlated with the alpha desynchronization in the posterior cortex in the persons with high intuition, whereas the persons with low intuition characterized by the alpha synchronization.

[Aging-induced differences in relationships between intelligence and self-assessment of quality of life].

Relationships between a self-assessment of quality of life and level of verbal, figurative and social intelligence in three age groups of students (middle age 63,9±5,8, 32±7,2, and 19,7±1,5 years; 90 % women) are studied. The group of elderly people differed from younger in low values of an integrated indicator physical health according to SF-36 questionnaire, especially - on scales physical and role functioning, and decreased figurative and social intelligence at relative constancy of verbal IQ. The different age-associated forms of interrelation of components of intelligence and quality of life are found: positive correlation between social intelligence and role functioning scores at senior persons; more numerous positive correlations between verbal and figurative intelligence and indicators of quality of life including integrated indicator of mental health in the thirty-year-old group; and positive correlation between verbal intelligence and values on a scale physical functioning, but negative correlations between figurative intelligence and role functioning and between social intelligence and an integrated indicator physical health for the twenty-year-old group.
