Functional brain asymmetry and the proper name
Keywords: adjustment, long-term weak acoustic stimuli, proper name, functional brain asymmetry
AbstractThere are several published works on the influence of long-term weak acoustic stimuli onto living organisms and their development. In this context, functional brain asymmetry (FBA) parameters were studied in correlation with the proper name. A. R. Luria sensorimotor tests (the dominant thumb when “locking” hands, the dominant eye, the dominant hand when crossing hands (the Napoleon’s pose), the dominant palm when applauding, the dominant ear) were used. With the data collected, we calculated relative difference in the numbers of the “right” and “left” in the group of certain name bearers for each test, %: thumb – (R-L)t, eye – (R-L)e, hand – (R-L)h, palm – (R-L)p, ear – (R-L)e, total for all tests – Σ(R-L), %. 1,136 men and 2,140 women born in 1920–1991 were examined. With the Fisher’s criterion, significant differences were detected in the bearers of various names, p≤0.05÷0.001, as well as the differences by 1–2 FBA parameters in the namesake persons belonging to different generations (born in 1971–1991 – “young” and born in 1920–1970 – “old”), p≤0.05÷0.001. The conclusion was that among the known functions of the proper name there is also an adaptive function.
