Introduction
According to several theories of temperament, it is based on the physiological mechanism consisting of various biological factors. Aim of this study was to examine whether blood groups in the system ABO and Rh are one of this physiological factors.
Methods
The Regulatory Theory of Temperament (RTT) invented by J. Strelau was the theoretical basis of this study. Temperament was measured with the Formal Characteristics-Temperament Inventory (FCB-TI) invented by Strelau. Responders declared their blood groups and their declarations were confirmed by the serological tests. The study included 320 individuals: 161 females and 159 males. They were divided into subgroups according to the blood groups ABO and Rh.
Results
It was found, among other, which in case of such temperamental traits as activity and sensitivity blood groups ABO and Rh really differentiate examined responders.
Discussion
The results are significant only at the level of 4% to 6% of the explained variance but it is sufficient to consider blood type as the one component of the temperament physiological mechanism.
Conclusion
Blood type might be the one of elements of the physiological mechanism of temperament. However, a degree of blood type relationship with temperamental traits seems controversial and requires confirmation in further studies.
