Search for environmental factors affecting temperament traits of young people of the Yakut nationality

For the first time, study of the influence of environmental factors (place of birth - city/village, season of birth, birth order, number of children in the family, smoking addiction, level of stressful situations experienced) on temperament traits in Yakuts (n=237) was carried out. To assess temperament traits - extraversion/ introversion and neuroticism - the Russian version of the questionnaire by G. Eysenck was used. It was found that the peculiarity of the studied sample is a high level of neuroticism: in men - 46%, in women - 72%. When analyzing the associations of temperament traits with various environmental factors, it was found that neuroticism rates in young people correlate with the number of traumatic events experienced in their childhood. In addition to the stress factor, temperament traits may be influenced by the season of birth: in women born in the spring and summer, on average, higher rates of extraversion are observed, and those born in autumn and winter have increased rates of neuroticism.
