INFLUENCE OF SEROLOGICAL MARKERS OF BLOOD GROUPS UPON THE DEVELOPMENT OF VISUAL MEMORY IN HIGH SCHOOLERS AND STUDENTS

OBJECTIVE: The aim: To investigate the influence of serological markers of blood groups of the AB0 system upon the development of short-term visual memory in high schoolers and students. PATIENTS AND METHODS: Materials and methods: The research involved 13-16-year-old high schoolers (boys) (n = 139) who were involved in various sports: group A - speed and strength sports (n = 74); group B - endurance sports (n = 65). The control group consisted of 13-16-year-old high schoolers (n = 106) and 17-20-year-old students (n = 212) who were not engaged in sports. The study of short-term visual memory was conducted using the "Memory for geometric shapes" method. RESULTS: Results: It was found that high schoolers and students with the 0(I) blood group have the best associative coupling with the properties of short-term visual memory. CONCLUSION: Conclusions: The use of serological markers of blood groups according to the AB0 system is possible in the genetic prediction of the development of visual memory in high schoolers and students. Herewith, the associative coupling is more pronounced in juvenility than in adolescence.
