Sažetak
A person’s adjustment to the environment depends largely on the cognitive abilities, and not only on the locomotive and sensory abilities. According to this, the principle of the symmetrical function of the both brain hemispheres has been abandoned in favour of another, more developed principle, based on the different function of each of the brain hemispheres. Nevertheless, the situation is totally different in some activities, like in the analyzing the sensory signals that control certain movements that must be performed symmetrically, thus, must be derived from identical nervous sets in each hemisphere. According to this point of view the manifestation of left-handedness can reasonably follow the conception that being left-handed is not a mistake, it is simply a less frequent occurrence that is based on the fact that certain activities are present in one hemisphere and not in the other. In other words, the specialization of one hemisphere depends on the type and the quantity of the information it receives, and on the synaptic surface which gives a privileged role to one hemisphere based on anatomic differentiation. In the light of this experience it is completely wrongful to force a child to switch to the right hand when writing or drawing. The possible consequences of a forceful redirection of the left-handedness in children are usually permanent and manifest themselves in locomotive abilities, speech, and mental development.
