developed. Also, they have symmetrically located speech zones, while in right-handed these 
zones are mainly localized in the left hemisphere. So that left-handers process information 
faster, adapt more easily to the environment and are often talented in a variety of areas. 
These issue was considered by diverse types of scientists and researchers as

others tries to find the main reason of left-handedness and the influence it to the abilities. 
Russian scientist E.I Nikolaev worked on analyzing left-handed children which 
interested me with its detailing this topic. In fact, handedness determines by hand which is 
used to write and to do most of actions. However, he believes that people accidentally use 
different hands to do different actions, wherein one of the hands makes small movements 
while another one makes big and heavy movements. In his opinion handedness is the 
advantage of the right or left hand observed in a person in the strength of dexterity and hand 
speed. If person’s left hand is faster- he is left-handed, if his right hand is faster –right-
handed. In addition Nikolaev underlines people using both hands simultaneously fast to do 
works and these kinds of people are called ambi-dextor. 
Nikolaev also considers three causes of left-handedness: hereditary transmission of 
a trait; intrauterine or birth trauma; influence of environmental factors. The researcher also 
claims that there is no exact evidence that left-handedness can be transmitted from parents. 
Using an example, he describes the research work of scientists who repeatedly tried to 
develop a line of mice, all individuals of which would prefer the left paw. To do this, they 
crossed left-pawed mice, then only left-pawed mice were selected from their offspring, and
