Abstract (en)
The lateralization of upper limbs, i.e. the tendency to use one arm
more often in comparison to the other one while performing
unimanual actions is the most obvious example of cerebral
lateralization and it represents a characteristic of human population.
The percentage representation of right-handed persons in comparison
to the left-handed is approximately 90%-10% on the global level. The
representation of left-handed persons is significantly lower than the
right-handed, which was taken as the basis of a lateralization
phenomenon research. For the sake of this research, lateralization is
defined through seven unimanual skills, the performance of which
requires precision. Based on the data analysis, both direction and
degree of lateralization, as well as ipsilateral correlation with other
organs (leg, eye and ear) were defined. The aim of this research was
also to determine the potential correlation of hand lateralization with
the observed phenotypic and cognitive characteristics of examinees,
as well as to predictability of hand lateralization in relation to
observed characteristics. It was concluded that the lateralization
degree is more expressed with the right-handed, as well as with
females. What was also observed was that this characteristic is
stabilized later in life, meaning it is more expressed with older
examinees in comparison to the younger ones. In addition to that, the
higher lateralization degree indicates a more expressed ipsilateral
correlation with the legs, eyes and ears. Hand lateralization is not a
predictor of cognitive process speed, but can be correlated to learning
and thinking styles. The representation of handedness direction in
examinees’ families was observed through three generations of
relatives and it indicates a genetic basis, especially in the cases of a
left-handed mother or left-handedness in the mother’s family. Among
the observed phenotypic characteristics of the examinees (hair and
eye color, ear lobe shape, Darwin’s tubercle, finger overlapping,
irregular articulation of the sound R, diastema), finger overlapping is
the only characteristic that can be correlated to the hand lateralization.
