It is called laterality to preference that most human beings manifest, although it can also manifest itself in plants and animals, on the one hand of their own body.
Laterality implies a spontaneous preference in the use of organs located, either on the right or left side, such as: arms and legs. Meanwhile, one of the clearest examples of laterality is that of the left-handed, the natural tendency with which some people are born that leads them to use the left hand par excellence.
It should be noted that most human beings are right-handed, showing, therefore, a predominance of the right side and although the causes that cause laterality are not yet fully defined, what is assumed is that the left cerebral hemisphere it controls the opposite side of the body, which also happens to be the predominant side.
But apart from the biological explanation that somehow clarifies the predominance of the right side of the body, there is also a cultural reinforcement that marks the predominance of the right side, because, in the Spanish language, the word sinister (on the left) It is usually used with a negative, pejorative connotation, on the other hand, the opposite occurs with the right, culturally linked to concepts such as rectitude and honesty, among others.
When an individual is forced to use the opposite hand to the one he habitually uses predominantly, it is called forced laterality.
For his part, the ambidextrousIt is an individual who is able to write without any inconvenience and with the same clarity with his two hands, right and left, and who can use both sides of his body with the same skill and predisposition.
Ambidexterity is a rare situation, although, in the long run or in the short, the individual will always end up showing the inclination to one particular side.
And the crossed laterality occurs when a person writes with his left hand but eats and plays sports with his right hand.
