ASSOCIATION BETWEEN DOPAMINE RECEPTOR GENE (DRD4) AND DOPAMINE TRANSPORTER GENE (DAT-1) AND TEMPERAMENTAL TRAITS: EMOTIONAL REACTIVITY AND ACTIVITY

In this study, the authors examined the association between high and low level of activity and emotional reactivity as two temperamental traits and DRD4 and DAT-1 gene polymorphisms in healthy men aged from 18 to 27 lat (M=21.03; SD=2.23). The data analysis performed with PCR method has shown that the DRD4 polymorphism was significantly associated with emotional reactivity (p=0.027), while no significant association in genotype was observed between activity and emotional reactivity and polymorphism in the DAT-1 gene.
