Human behaviour genetic research has been conducted at the University of Warsaw for more than 15 years. The main focus of this work have been the origins of individual differences in temperament and other personality traits. Other areas of interest include attitudes, risk factors for human health, and posttraumatic stress disorder (PTSD). The majority of the research is conducted using quantitative genetic methods although recently work using molecular techniques has also begun to develop. This article reviews the most important directions and findings of this research.

(Title in Polish - 'Polimorfizm w genie transportera dopaminy (DAT 1) i postrzegalny stopien zagrozenia zycia a zaburzenie po stresie traumatycznym w grupie powodzian'). In this study thye authors examined possible associations between polymorphism in the dopamine transporter gene (DAT 1) and perceived threat of life and PTSD in the group of flood victims aged from 14 to 62. The participants of the study were asked to fill in two questionnaires measuring the intensity of PTSD symptoms. They were also asked to appraise the threat of life during traumatic event. The genotype of the participants were analyzed using PCR method. The authors demonstrated the association between perceived threat of life and the intensity of PTSD symptoms. Additionally, they showed the interaction between the DAT 1 genotype and perceived threat of life with respect to the intensity of PTSD symptoms.

This study has sought to identify the determinants of religious fundamentalism. The following hypothetical determinants were tested: genetic influence, environmental influence, and such psychological variables as anxiety and assumptions about the nature of the social world. It was assumed that trait anxiety and assumptions about the social world are mediators of religious fundamentalism. The study was run on 112 participants (29 women and 83 men) aged from 18 to 28 years; the sample consisted of 19 monozygotic and 37 dizygotic pairs of twins reared together. The results of structural equation modelling showed that religious fundamentalism is mainly determined by environmental influences (38% heritable) whereas trait anxiety and assumptions about the nature of the social world are largely genetically determined (60% heritable). Correlation analysis revealed a positive relationship between trait anxiety and negative social world view but, contrary to the hypothesis, the results of multiple regression analysis suggest that trait anxiety is the only predictor of religious fundamentalism.
