The purpose of the research was to verify the hypothesis of the effect of climatic environmental conditions of developmental peculiarities of interhemispheric asymmetry and cognitive functions on population level. Some scientists consider that adaptation to extreme climatic conditions of north of Siberia or Alpine regions promote accumulation of left and symmetric signs of asymmetry in populations and in cognitive processes the dominant population sign is visual perception and concrete-aspect schemes of mentality (Arshavsky V.V., 1988; Leutin V.P. et.al., 1997; Tyinalieva B.K., 2003; Yizhikova E.A., 2000).

We examined urban and rural population of preschool and early school age children living in northern and southern regions of Irkutsk region. State and dynamics of interhemispheric asymmetry and high psychic functions were studied applying complex of neuropsychologic methods. Then results of representative samplings of urban and rural children were compared using statistical methods.

We did not find any differences neither in distribution of lateral signs nor in peculiarities of cognitive processes formation. Significant differences in these parameters were revealed at comparison of urban and rural children’s population irrespective of place of living – in the north or in the south. Formation of lateral phenotype and specific features of cognitive processes formation in rural children’s population make it alike northern and Alpine populations that are mostly rural. Thus the obtained results showed no significant differences in formation of interhemispheric asymmetry and development of psychic functions in northern and southern subpopulations of urban and rural children. Probably effect of climatic factors has secondary significance.
